Answer:
The reaction can produce 287 grams of iron(II) carbonate
Explanation:
To solve this question we must find the moles of iron(II) chloride that react. Using the chemical equation we can find the moles of iron(II) carbonate and its mass -Molar mass FeCO3: 115.854g/mol-
<em>Moles FeCl2:</em>
1.24L * (2.00mol / L) = 2.48 moles FeCl2
As 1 mol FeCl2 produce 1 mol FeCO3, the moles of FeCO3 = 2.48 moles
<em>Mass FeCO3:</em>
2.48mol * (115.854g / mol) =
<h3>The reaction can produce 287 grams of iron(II) carbonate</h3>

Yes because what other else can a scientist have
Answer:
759779.6 torr
Explanation:
Initial volume, V₁ = 4001 mL
Final volume, V₂ = 3002 mL
Initial pressure, P₁ = 750.1 atm
We need to find the final pressure at a constant temperature. Let it be P₂. 
We know that,
1 atm = 760 torr
So,
999.71 atm = 759779.6 torr
Hence, there will be 759779.6 torr pressure.
Answer:
If the star has smaller mass than the Sun, it can fuse hydrogen into helium for at least a trillion years. The larger a star, the shorter its life because it fuses hydrogen into helium much more quickly. A star whose mass is more than 20 Suns will run out of hydrogen in only a few hundred million years.
