The sun’s core is made of solid rock. True or false
1 answer:
Answer:
False
Explanation:
Heres what its made of:
The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.

<u>Answer:</u> The mass of acetic acid that can be produced is 30.24 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
- <u>For acetaldehyde:</u>
Given mass of acetaldehyde = 22.2 g
Molar mass of acetaldehyde = 44 g/mol
Putting values in equation 1, we get:
- <u>For oxygen gas:</u>
Given mass of oxygen gas = 12.6 g
Molar mass of oxygen gas = 32 g/mol
Putting values in equation 1, we get:
The given chemical equation follows:
By Stoichiometry of the reaction:
2 moles of acetaldehyde reacts with 1 mole of oxygen gas
So, 0.504 moles of acetaldehyde will react with = of oxygen gas
As, given amount of oxygen gas is more than the required amount. So, it is considered as an excess reagent.
Thus, acetaldehyde is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
2 moles of acetaldehyde produces 2 moles of acetic acid
So, 0.504 moles of acetaldehyde will produce = of acetic acid
Now, calculating the mass of acetic acid from equation 1, we get:
Molar mass of acetic acid = 60 g/mol
Moles of acetic acid = 0.504 moles
Putting values in equation 1, we get:
Hence, the mass of acetic acid that can be produced is 30.24 grams
