Assoli18 [71]3 years ago
6 0
[ H₃O⁺] = 10 ^ - pH

[ H₃O⁺ ] = 10 ^ - 7.30

[ H₃O⁺ ] = 5.011 x 10⁻⁸ M

hope this helps!

28.7 l of propane, c3h8, are consumed in a combustion reaction. how many grams of water are produced?
Travka [436]
The chemical reaction would be:

C3H8 + 5O2 = 3CO2 + 4H2O

For this case, we assume that gas is ideal thus in every 1 mol the volume would be 22.41 L. We calculate as follows:

28.7 L C3H8 ( 1 mol / 22.41 L ) ( 4 mol H2O / 1 mol C3H8 ) ( 18.02 g / mol ) = 92.31 g H2O produced

Hope this answers the question.

Answer:

<u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form  a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)

Therefore, <u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

How do anion formation and valence electrons relate?
sveta [45]

Answer 1: Atoms gain valence electrons to form anions.

Explanation:

Anions are negatively charged species of an ions. Anions are formed when atoms with nearly complete octet gains electrons.

Answer 2: Emission spectrum

Explanation:

When ever electron jumps from higher energy to lower energy level energy is emitted out in the form of light.The wavelength of the light is given as \lambda:

\lambda=\frac{hc}{E} , E = energy, c= speed the light, h= planck constant

Answer 3: Two atoms of silicons could combine by fusion in order to create nickel.

Explanation:

Silicon has atomic number of 14 with atomic mass of 28 u.

nickel has atomic number of 28 with atomic mass of 59 u.

Two different isotopes of silicon atom will fuse together to give nickel.

^{29}Si_{14}+^{30}Si_{14}\rightarrow^{59}Ni_{28}
