Answers
The overall balanced equation for the transformation of bromobenzene to benzoic acid via a Grignard reaction is:
C6H5Br + Mg → C6H5MgBr (Grignard reagent formation)
C6H5MgBr + CO2 → C6H5COOMgBr (Grignard reaction with carbon dioxide)
C6H5COOMgBr + H2O → C6H5COOH + Mg(OH)Br (Acid-base reaction)
Mechanism:
1. Bromobenzene reacts with magnesium to form the Grignard reagent, phenylmagnesium bromide (C6H5MgBr).
2. Phenylmagnesium bromide reacts with carbon dioxide to form magnesium benzoate (C6H5COOMgBr).
3. Magnesium benzoate is hydrolyzed by water to produce benzoic acid (C6H5COOH) and magnesium hydroxide bromide (Mg(OH)Br).

Answers
Answer:
d < c < a < b
Explanation:
The molar mass of a compound is the sum of the atomic masses of all the atoms in its chemical formula. Here are the molar masses of the four compounds you have:
a. SiH4: (1 × 28.09 g/mol) + (4 × 1.01 g/mol) = 32.13 g/mol
b. Co: 58.93 g/mol
c. CH3OH: (1 × 12.01 g/mol) + (4 × 1.01 g/mol) + (1 × 16.00 g/mol) = 32.05 g/mol
d. C2H6: (2 × 12.01 g/mol) + (6 × 1.01 g/mol) = 30.07 g/mol
So, from smallest to largest molar mass, the order is: d < c < a < b.
1 N2H4+ 2 H2O2 = 1 N2+ 4 H2O
if 0.750 mole N2H4 and 0.500 H2O2 are available for the reaction, how many grams of water can be made? (show your work for both problems)
Answers
The mass of water that can be made would be 36.03 grams.
Stoichiometric problemFrom the balanced chemical equation:
1 mole N2H4 produces 4 moles H2O2
0.750 mole N2H4 will produce = 0.750 x 4/1 = 3.000 moles H2O2 (limiting reactant)
0.500 mole H2O2 is used, which is less than the amount produced by N2H4, so it is also a limiting reactant.
Now, we can use the mole ratio between H2O2 and H2O to calculate the moles of water produced:
1 mole H2O2 produces 4 moles H2O
0.500 mole H2O2 will produce = 0.500 x 4/1 = 2.000 moles H2O (limiting reactant)
Finally, we can use the molar mass of water to convert the moles of water to grams:
2.000 moles H2O x 18.015 g/mol = 36.03 g H2O
Therefore, 36.03 grams of water can be made from the given amounts of N2H4 and H2O2.

Calculate the mass percentage composition of nitrogen in acetaminophen, C8H9NO2
Answers
The mass percent composition of nitrogen in acetaminophen is 9.26 %.
The mass percent composition of an element is the percentage of the ratio of the molar mass of that element to the molar mass of the entire compound. Acetaminophen represented as C8H9NO2 is a drug that is used as a pain reliever.
First, we will calculate the molar mass of this compound. For this, we should know the mass of each element present in the compound.
mass of C = 12, mass of H = 1, mas of N = 14, mass of O = 16.
Now, we will calculate the molar mass of acetaminophen
= 12*8+ 1*9+14*1+16*2
= 151 g
Now, we have to calculate the mass percent composition of Nitrogen.
The molar mass of nitrogen = 14g
The molar mass of the entire compound = 151 grams.
Mass percent composition of N = (mm of N ÷ mm of C8H9NO2) ×100
= (14/151) × 100 = 0.0926 × 100
= 9.26 %
Therefore, the mass percent composition of nitrogen in acetaminophen (C8H9N02) is 9.26%.

Answers
The statement is FALSE. Non-ferrous metals can be hardened by heat treatment, although the mechanisms and processes involved may differ from ferrous metals.
Heat treatment techniques such as precipitation hardening can be used to increase the strength of non-ferrous metals. Non-ferrous metals are metals or alloys that do not include iron (or iron allotropes, such as ferrite, etc.) in significant quantities. Non-ferrous metals are employed because they have desired qualities like reduced weight (for example, aluminium), greater conductivity (for example, copper), non-magnetic characteristics, or corrosion resistance (for example, zinc), even though they are often more expensive than ferrous metals. In the iron and steel sectors, several non-ferrous materials are also employed. Bauxite, for instance, is used as a flux in blast furnaces, whereas wolframite, pyrolusite, and chromite are utilised to create ferrous alloys.

What is the mole-to-mole relationship for the reactants?B2H6 + 3O2⟶2HBO2 + 2H2O
Answers
The balanced chemical equation you provided is:
B2H6 + 3O2 ⟶ 2HBO2 + 2H2O
In this equation, B2H6 (diborane) is the reactant on the left side, and O2 (oxygen gas) is also a reactant. According to the coefficients in the balanced equation, the mole-to-mole relationship between B2H6 and O2 is 1:3.
This means that for every 1 mole of B2H6 that reacts, 3 moles of O2 are consumed. Similarly, for every 3 moles of O2 consumed, 1 mole of B2H6 reacts. The coefficients in the balanced equation represent the stoichiometric ratio between the reactants.
Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. In this case, the stoichiometry tells us that the reaction requires a 1:3 ratio of B2H6 to O2 for complete reaction.
Understanding the mole-to-mole relationship is crucial for performing calculations involving reactants and products. It allows us to determine the amounts of substances involved in a chemical reaction and can be used to calculate the theoretical yield of a product or the amount of reactant needed for a desired product yield.

now lets see how evaporation affects concentration. add 10 shakees of solute to 1/2 L of solvent.
Answers
By removing the solvent (in this case, water), evaporation can leave behind the solute and raise the concentration of a solution.
The percentage of the solution that is made up of the solute is one technique to quantify the concentration of a solution. Three methods can be used to calculate this ratio:
(1) the mass of the solution is divided by the mass of the solute;
(2) dividing the volume of the solute by the amount of solution; or
(3) Mass of the solute divided by volume of the solution.
The concentration of the given solution will be increased by adding 10 shakes of solute to 1/2 of solute. The characteristics of the solute and solvent, as well as additional elements like temperature and air conditions, will all have an impact on how much the concentration changes.
The concentration will keep rising if the solution is permitted to evaporate, until there is no more solvent left for the solute to dissolve in.

Answers
The addition of 20 ml of water to a solution of ethanoic acid with a pH of 3 will cause the concentration of H+ ions to decrease, leading to a decrease in the amount of H+ ions present in the solution.
The pH scale is a measure of the concentration of H+ ions in a solution. A pH of 3 indicates a relatively high concentration of H+ ions. When water is added to the solution, it will dilute the ethanoic acid and increase the total volume of the solution. However, since water is neutral and does not contribute H+ ions, the concentration of H+ ions will decrease as the overall volume increases. This results in a decrease in the amount of H+ ions present in the solution. Therefore, the correct answer is d. The concentration of H+ ions will decrease.
