How many liters are in 27.6 g of copper phosphate with a molarity of 6.03 ?

Oxidation D) occurs when the electrons are lost from an atom or compound. Oxidation refers to a chemical reaction where there is a transfer of electrons from one substance to another.

During oxidation, the substance that loses electrons is known as the reducing agent while the substance that gains electrons is known as the oxidizing agent. When an atom or compound loses electrons during oxidation, it becomes more positively charged, and this results in a decrease in its negative charge.

For example, when iron rusts, it undergoes oxidation as it loses electrons to oxygen. The iron atoms lose their electrons, and as a result, they become positively charged. This causes the iron compound to have a more positive charge than it did before the oxidation process.

In summary, oxidation occurs when electrons are lost from an atom or compound, which results in a decrease in the negative charge of the compound or atom.

The given statement " William Aston created the mass spectrograph to analyze and separated them, found 218 and found mass and percent abundance of each atoms" is false.

The mass spectrograph was not invented by William Aston. It was actually invented by J.J. Thomson in the early 20th century.

J.J. Thomson's work with the mass spectrograph led to the discovery of isotopes, which are different forms of an element with the same number of protons but different numbers of neutrons. Isotopes have different masses, and the mass spectrograph allowed scientists to separate and analyze them based on their mass-to-charge ratio.

The process of using a mass spectrograph to determine the mass and percent abundance of isotopes is known as mass spectrometry. It involves ionizing a sample, separating the ions based on their mass-to-charge ratio, and detecting the ions to determine their abundance.

Explanation: Gas molecules influence each other only by collision

it is c because canivores eat only meat while herbivores eat only plants so it is most likely a herbivore because it knows flavours that are good for it

A carnivore is more likely to have taste buds for umami flavors so it can taste the flavors of meat, while a herbivore is less likely because plants do not generally have umami flavors. Hence, option B is correct.

One of the five fundamental flavors is umami. It has been characterized as savory and is present in cooked meats and broths. Glutamates and nucleotides, which are plentiful in meat broths and fermented foods, trigger the taste receptors that allow us to detect umami.

Meats, shellfish, fish (including fish sauce and preserved fish like maldive fish, Katsuobushi, sardines, and anchovies), tomatoes, mushrooms, hydrolyzed vegetable protein, meat extract, yeast extract, and cheeses are examples of foods with a strong umami flavor.

Carnivores are eating meat while herbivores are plant eaters. Hence, slight chance for herbivores to taste the umami flavor. Therefore, option B is correct.

Answer:

C. 7.020 x 10^2 g

Explanation:

To convert to scientific notation, move the decimal until there is only one digit greater than 1 and less than 10 before the decimal. In this case, the 7. (Depending on the conversion, you will either move the decimal to the left or right. In this question, you will need to move it left. When you move the decimal left, you inherently think you are moving it in the negative direction, but your final answer will be a positive exponent. The opposite is true for movement in the right direction, leaving a negative exponent in your final answer.)

Then, count the number of places that you moved the decimal from the original number (in this case, you moved it 2 decimal places to the left).

Because you moved the decimal 2 places to the left (-), when you write it in scientific notation, you want to annotate the exponent as the opposite, (+), so that you do not lose the equivalence of the original number (in this case, state it as 10^2 as in choice C).  

Note: Once you do your conversion, you can plug it into your calculator and press "=" to verify that you did not change the number in doing your conversion.

Taking into account the definition of Scientific notation, the correct representation of 702.0 g in scientific notation is option C. 7.020×10² g.

First of all, scientific notation is a quick way to represent a number using powers of base 10. This notation is used to be able to express very large or very small numbers very easily.

In this reaction, H2S is a acid and Ba(OH)2 is a base. When an acid and a base react, they neutralize each other and form water and a salt. In this case, the acid is H2S and the base is Ba(OH)2, so the products of the reaction are water (H2O) and the salt Bas.

The elements in the same column of the periodic table was having a same amount of valence electrons.

define valence electrons ?

A valence electron is an electron connected with an atom in the outer shell that can participate in the production of a chemical bond if the outer shell is not closed. A shared pair originates in a single covalent connection, with both atoms donating one valence electron.

The existence of valence electrons can influence an element's chemical characteristics, such as its valence—whether it can connect with other elements and, if so, how easily and how many times. In this approach, the reactivity of a particular element is strongly reliant on its electrical arrangement. A valence electron can only reside in the outermost electron shell of a main-group element; a valence electron can also exist in the innermost electron shell of a transition metal.

The choice of chemical ingredients in airbags influences their effectiveness in several ways:

Time: Sodium azide ignites faster than ammonium nitrate, decomposing in under 1/25 sec vs. requiring heating to ignite. Sodium azide's faster ignition leads to quicker airbag inflation.

Volume: Sodium azide produces 3 moles of gas from 2 moles of solid, while ammonium nitrate produces 3 moles of gas from 4 moles of solid to achieve the same total moles of gas. Less starting material is needed for sodium azide to produce the same volume of gas.

Amount used: To produce the same volume of gas, half the amount of solid sodium azide (2 moles) is required compared to ammonium nitrate (4 moles). Less ingredient is needed for sodium azide.

Popped/Not inflated: Highly explosive compounds like nitroglycerin are too shock-sensitive and difficult to control, easily popping the airbag before it fully inflates. Sodium azide and ammonium nitrate can be controlled to properly inflate the airbag.

Enough/Inflated perfectly: Advanced airbags with sensors can determine the optimal amount of each chemical to inflate based on occupant size. Multiple stages of inflation are possible for perfect inflation control and cushioning. Single-stage less controlled explosions may over- or under-inflate the airbag.

Data:

Equation 1: General decomposition equation

Equation 2: Decomposition of sodium azide

Equation 3: Decomposition of ammonium nitrate

Sodium azide → 3 moles gas / 2 moles solid

Ammonium nitrate → 3 moles gas / 4 moles solid

Nitroglycerin → 5 moles gas / 4 moles liquid

In summary, the choice of chemical impacts how quickly, how much, and how controllably the airbag inflates. Sodium azide and ammonium nitrate can be optimized and controlled, while nitroglycerin is too volatile. Less material is needed for faster-acting sodium azide. Advanced sensors enable perfectly inflating multistage airbags regardless of the chemical mixture. The data and equations show the mole ratios for each chemical decomposition.

Answer: PV = nRT

A gas at STP... This means that the temperature is 0°C and pressure is 1 atm.

R is the gas constant which is 0.08206 L*atm/(K*mol)

Rearranging for volume

V = nRT/P

The temperature and number of moles are held constant. This means that this uses Boyle's Law. (The ideal gas law could be manipulated to give us this result when T and n are held constant.)

PV = k

where k is a constant.

This means that

P₁V₁ = k = P₂V₂

P₁V₁ = P₂V₂

(1 atm) * (1 L) = (2 atm) * V₂

V₂ = 0.5 L

The new volume of the gas is 0.5 L.

The number of candies each of the grandchild would get is 24, 18 and 16 candies respectively.

Given the following data:

To determine the number of candies each of the grandchild would get:

Note: The candies were distributed to the grandchildren inversely proportional to their ages.

Mathematically, this is given by this expression:

\(Candies \; \alpha\; \frac{1}{Age}\)  ≡ \(C = \frac{k}{A}\)

Thus, the above expression is re-written for all the grandchildren as follows:

\(58 = \frac{k}{6} + \frac{k}{8}+\frac{k}{9}\)

Lowest common multiple (LCM) of 6, 8 and 9 is 72.

\(58=\frac{12k +8k+9k}{72} \\\\58=\frac{29k}{72}\\\\29k =72 \times 58\\\\29k =4176\\\\k=\frac{4176}{299}\)

k = 144.

For the first grandchild:

\(Candy = \frac{k}{6} \\\\Candy = \frac{144}{6}\)

Candy = 24 candies.

For the second grandchild:

\(Candy = \frac{k}{6} \\\\Candy = \frac{144}{8}\)
