Answer:
CaCO3 (s) → CaO (s) + CO2 (g)
The mass of carbonate that must have reacted was 43.03 grams
Explanation:
CaCO3 → CaO + CO2
Relation between reactant and product is 1:1
Let's apply the Ideal Gas Law to find out the moles of CO2 which were produced.
P . V = n . R . T
1 atm . 23 L = n . 0.082 L.atm/mol.K . 653K
(1atm . 23L) / (0.082 mol.K/L.atm . 653K) = n
0.43 moles = n
0.43 moles of CO2, were produced from 0.43 moles of CaCO3.
Molar weight of CaCO3 = 100.08 g/m
Mass = Molar weight . moles
Mass = 100.08 g/m 0.43 m = 43.03 g
You Would Need A(n) Blacklight Or AKA UV Light
The statement that best describes the relationship difference is most rocks are made out of minerals.
<h3><u>Answer;</u></h3>
F, Br, l
<h3><u>Explanation;</u></h3>
- Astatine is a member of the halogen family, elements in Group 17 (VIIA) of the periodic table.
- It is a highly radioactive element and it is the heaviest known halogen. Astatine is similar to the elements above it in Group 17 (VIIA) of the periodic table, especially iodine.
-
One property of iodine is that it tends to collect in the thyroid gland
