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>
Answer:
e. 4.847 x 10-19 J
Explanation:
From the given information:
The equation connecting the photon energy and the wavelength is:

where;
= 6.626 * 10 ^{-34} J.s
= 3.00 * 10^8 m/s
wavelength 

To determine the photon energy of violet light

= 4.847 × 10⁻¹⁹ J
I think the molecular formula would be CHO.
