Answer:
The answer is
<h2>12,574,750.83 moles</h2>
Explanation:
In order to find the moles of CO2 we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 7.57 × 10^30 molecules of CO2
We have
We have the final answer as
<h3>12,574,750.83 moles</h3>

Answer:
<em>(H30+)= 1x10^-6 M</em>
Explanation:
Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:
1x 10-8 mol/L equals to1x10-8 M
(H3O+) x (OH-) = 1x10^-14
(H30+)x 1x 10^-8 =1x10^-14
(H30+)= 1x10^-14/1x 10^-8
<em>(H30+)= 1x10^-6 M</em>
Answer:
Na + CaSO4 = Na2SO4 + Ca
Explanation:
single displacement (substitution)
Answer: true
Explanation: Electrons orbit the nucleus of an atom the way that planets revolve around the Sun. The electrons are like the planets in the solar system. The sun is like the nucleus in the solar system. The answer to the question is true.
These metallic substances are actually metal salts, which produce luminescent light of different colors when they are dispersed in the air. This light is produced by electrons inside the metal atoms
