How many different compounds are involved in the reaction shown below?

2 NH3 + H2SO4 → (NH4)2SO4

Answer:

1. All the possible energy transformations that occur with a dishwasher that uses electrical energy are heat energy because the dishwasher uses the electrical energy to heat the water, also electrical energy is transformed into kinetic energy and sound energy the reasoning behind this is that the parts moving inside the dishwasher is causing the sound.

2. Take as an example a light bulb inside a lamp to illuminate a room. When you plug it in a plug and turn it on, light is generated. More precisely, heat (Joule effect) is produced inside the lamp by its internal filament (conductive material) when it passes through the electrical energy, generated by the friction of the atoms that are inside it when it encounters a resistance.

1.Our results indicate that, at higher biodiversity, the impact of acidification on otherwise highly vulnerable key organisms can be reduced by 50 to >90%, depending on the species

2.Positive attitude is sometimes all it takes to turn a bad situation around. On the other side, a bad attitude can take a problem and quickly make it worse. Helps You Make Good Decisions – Anger clouds your judgement. When you let yourself get upset, you impact your ability to make good decisions.

Answer:

abiotic sand sunlight water currents

biotic fish bacteria jellyfish

pretty sure this is right

because biotic is living and abiotic is nonliving

Answer:

39

Explanation:

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

Answer: 90 degrees F

Explanation:

Answer:

8.47 x 10^3

Explanation:

So since we only want 3 sig figs we have to round our last digit up and then it is 10^3 because we moved the decimal place to the left 3 times to get 8.47

Comment if you have any other sig fig questions, happy to answer them!

Explanation:

Your test is over so you don’t need proof

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

Cattle grazing will increase soil erosion as it is removing the soil's vegetation and therefore exposing it more to the wind and rain.

Contour ploughing will help reduce soil erosion. By revolving the soil, and also planting after, but simply contouring can be enough, the capacity to withhold water, breaking its run-off will help contain the soil where it is rather than being pushed and taken away by water.

Deforestation will increase soil erosion by exposing the soil to water run-off and wind.

Hydroseeding can reduce soil erosion more than the sowing of dry seed, for example.

Planting vegetation reduces soil erosion as it creates protection to the soil from the weather and keeps it healthy for soil revolving animals that also contribute to reducing soil.

Answer:

4) Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Explanation:

Mixtures contain different substances with different physical properties, such as boiling point, melting point, solubility, density, and so on. These properties can be used to separate the individual substances in the mixture through various techniques. For example, distillation is a separation technique that relies on differences in boiling points of the substances in a mixture. When a mixture is heated, the substance with the lower boiling point will vaporize first, and it can be collected and cooled to form a pure substance. Similarly, other techniques such as chromatography, filtration, and crystallization also rely on differences in physical properties to separate mixtures.

On the other hand, chemical changes involve the rearrangement of atoms within a substance, resulting in the formation of a new substance with different properties than the original. While chemical changes can be used to synthesize new substances, they are not typically used to separate mixtures.

Answer:spectrum

Explanation:

Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.

So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.

But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.

So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?
