The process where water changes from a liquid to a gas

Looters break a statue into pieces. How do you expect the weathering of pieces of rock to change?

andreyandreev [35.5K]

The statue will weather faster because of more surface area.

If you boiled the water at the top of the mountain would you expect it to boil at 100Degree celsius

pochemuha

Depends on the height of the mountain. At 2500km (7500ft) it might boil-albeit reluctantly-at 100 degrees Celsius, but higher up not so much.

Classify the reactions as endothermic or exothermic....PLEASE HELP ASAP

elena55 [62]

1) Endothermic reactions:

a) The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.

There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).

b) Ammonium chloride dissolved in a beaker of water makes the beaker cold.

Dissolving this salt absorbs heat from beaker.

c) Water separates on hydrogen and oxygen when an electric current is run through it.

Electrolysis of water is the decomposition reaction (heat is required), because from one molecule (water) two molecules (hydrogen and oxygen) are produced. Water is separated into two molecules.

2) Exothermic reactions:

a) Three drops of concetrated sulfuric acid added to 100 milliliters in a beaker makes the beaker hot.

Energy is released, beaker absorbs that heat.

b) Uranium atoms are split to produce nuclear energy.

Nuclear energy is released.

c) Methane and oxygen are combined to produce methanol and heat.

Balanced chemical reaction: 2CH₄ + O₂ → 2CH₃OH + heat.

What can you infer if the fossil of a marine organism is found in an area that is now dry land?

Deffense [45]

Answer:

Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

hope it will help you have a great day bye and Mark brainlist if the answer is correct
