Which is classified as a renewable resource? A. coal B. wind C. oil D. uranium

Answers

Answer 1

Answer: The answer is B) Wind because wind will always be available, while coal, oil and uranium are objects we are digging up. This makes wind a renewable resource, therefore it is better for the environment because we can theoretically never run out of it. This is the reason we are starting to use wind to create energy; we can use it again.

Answer 2

Answer: The answer is obviously B. It is the only one that can continually be renewed without fail.

Consider the following reaction to generate hydrogen gas: Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g) The hydrogen gas is collected by displacement of water at 35.0 °C at a total pressure of 745 torr. The vapor pressure of water at 35.0 °C is 42 torr. Calculate the partial pressure of H2 (in atm) if 353.2 mL of gas is collected over water from this method.

2Na + 2H2O mc012-1.jpg 2NaOH+H2, what mass of Na is required to yield 22.4 L of H2 at STP? (The atomic mass of Na is 22.99 u.)

Answers

46.0g Na

Since 22.4L of anything at STP is one mole, you can use your mole fraction to easily determine the # of moles of Na to produce one mole of H2. In this case, 2 moles of Na yield 1 mole H2, so all you need to do now is convert to grams. (Moles x Molar mass) which is 2 moles Na X 23g . this gives you the answer of 46g of Na.

Which factor is generally responsible for high melting points?

Answers

Strong intermolecular ion-ion forces are responsible for high melting points. Thus the solid state requires close proximity and high order to have high melting point. Hope this answer helps. Good luck!

Answer;

Intermolecular forces.

Explanation;

Melting point is the temperature at which a solid melts or a solid changes to a liquid. In liquids melting point is similar to the freezing point.
Melting point of a substance depends on the molecular composition, force of attraction between molecules and also the presence of impurities.
A strong force of attraction between molecules results in a higher melting point. Such that stronger intermolecular forces results to a higher melting point.
For example, the melting point of ionic compounds is higher due to the strong electrostatic forces joining ions.

Rust on weathered rocks is caused by _____.saltation
oxidation
hydrolysis
abrasion

Answers

Rust on weathered rocks is caused by the process of oxidation. Oxidation is a process of chemical weathering that occurs when oxygen combines with minerals in rocks. rust occurs when oxygen combines with iron in rocks to form the reddish brown iron oxide.

Answer: The correct answer is oxidation.

Explanation:

Rust is a reddish-brown colored compound which is formed by the oxidation of Iron to form ferric oxide. The formula for this chemical compound is $Fe-2O_3$

Oxidation is defined as the reaction in which addition of oxygen takes place.

The reaction for the formation of rust is given by the equation, we get:

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)$

By Stoichiometry,

4 moles of iron metal reacts with 3 moles of oxygen gas to form 2 moles of ferric oxide.

Hence, the correct answer is oxidation.
