Answer:

The correct answer is d. Atoms share one or more pairs of electrons.

Explanation:

In a covalent bond, electrons of the last energy level are shared, to reach the octet (except for the Hydrogen that reaches its stability with 2 electrons). This type of bond occurs between two nonmetallic compounds. Example: H202 (hydrogen peroxide) formed between oxygen and hydrogen.

635 mL of a gas is at a pressure of 8.00 atm. What is the volume of the gas at standard pressure (STP)?

Sveta_85 [38]

The new volume at standard temperature and pressure is 5.08 L.

Explanation:

As per the kinetic theory of gases, the volume occupied by gas molecules will be inversely proportional to the pressure of the gas molecules. This is termed as Boyle's law.

So, pressure∝ $\frac{1}{volume}$

Thus, if two pressure and two volumes are given then,

$P_{1} V_{1} = P_{2} V_{2}\\$

Now, we known the values of P₁ = 8 atm, V₁ = 635 mL, P₂ = 1 atm and V₂ we have to determine. We are considering P₂ = 1 atm, because we have to determine V₂ at standard temperature and pressure. And standard pressure is 1 atm.

$8*635*10^{-3} = 1 *V{2} \\\\V_{2} = \frac{8*635*10^{-3} }{1} = 5.08 L$

Thus, the new volume at standard temperature and pressure is 5.08 L.

The students in Mrs. Smith's class used pH paper to measure the acidity levels between different samples of breakfast drinks. Th

masya89 [10]

Answer:

The most acidic solution had a pH of 3.27.

Explanation:

In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.

If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.

Conversely, the least acidic one had a pH of 3.88.
