Answer:

D

Explanation:

Protons have pretty much nothing to do with reactions, but electrons affect reactions because that is how elements bond. A neutral sodium atom has 11 electrons while a neutral neon atom has 10 electrons, meaning D is correct.

Living things respire to stay alive. In the mitochondria, sugar is combined with oxygen to produce energy, water and carbon diox
olya-2409 [2.1K]

Answer:

C6H12O6 + 6O2 → 6CO2 + 6H2O

Explanation:

Cellular respiration occurs in the mitochondria of cells. It is a process in which  sugar is combined with oxygen to produce energy, water and carbon dioxide. This is the major process by which energy is released in living organisms.

Aerobic respiration involves a series of chemical reactions.  These reactions commence with sugar and oxygen then it produces  carbon dioxide and water according to the reaction equation; C6H12O6 + 6O2 → 6CO2 + 6H2O.

What are Saturn's rings made up of and where are they found?(write like a sentences or two if u can)
Alenkinab [10]

Saturn's rings are made of ice and rock. These pieces vary in size. Some are as small as a grain of sand. Others are as large as a house. The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. They are found around the planet

Use Lewis theory to determine the chemical formula for the compound formed between Sr and N.
mariarad [96]

Answer:

Sr_3N_2

Explanation:

Hello,

In this case, since the Lewis theory is based on the bonds formation between atoms via the valence electrons, we can verify the chemical formula of the compound formed by strontium and nitrogen by noticing that strontium has two valence electrons as it is in group IIA, for that reason, two nitrogens should be available for bonding. Therefore, since nitrogen is in group VA, it is said that three electrons are required to attain the octet (maximum amount bonded electrons), for that reason, three strontiums are should be available for bonding. In such a way, the formula should be:

Sr_3N_2

Regards.

er solutions can be produced by mixing a weak acid with its conjugate base or by mixing a weak base with its conjugate acid. The
liubo4ka [24]

Answer:

You need to add 19,5 mmol of acetates

Explanation:

Using the Henderson-Hasselbalch equation:

pH = pKa + log₁₀ [base]/[acid]

For the buffer of acetates:

pH = pKa + log₁₀ [CH₃COO⁻]/[CH₃COOH]

As pH you want is 5,03, pka is 4,74 and milimoles of acetic acid are 10:

5,03 = 4,74 + log₁₀ [CH₃COO⁻]/[10]

1,95 = [CH₃COO⁻]/[10]

<em>[CH₃COO⁻] = 19,5 milimoles</em>

Thus, to produce an acetate buffer of 5,03 having 10 mmol of acetic acid, you need to add 19,5 mmol of acetates.

I hope it helps!
