Answer:
6.02 x 10²²molecules
Explanation:
Given parameters:
Mass of CO₂ = 4.4g
Unknown:
Number of molecules in CO₂ = ?
Solution:
To find the number of molecules in the given mass, we have to find the number of moles in the compound first;
Number of moles = 
Molar mass of CO₂ = 12 + 2(16) = 44g/mol
Insert the parameters and solve;
Number of moles = 
= 0.1mol
1 mole of a substance contains 6.02 x 10²³molecules
0.1 mole of CO₂ will contain 0.1 x 6.02 x 10²³molecules
= 6.02 x 10²²molecules
Answer:
True?
Im sorry I have no clue...
The "Imported Asset" refers to the image attached to this answer. And this is a true or false question regarding whether the structure shown is a cyclohexane ring containing two attached methyl groups.
The correct answer is
TRUE. The ring structure is composed of 6 carbons which makes it a cyclohexane, and there are two methyl groups (-CH3) attached to the ring in the 1- and 3-positions of the ring. The full name of this structure is 1,3-dimethylcyclohexane.
Answer:
Complete ionic equation:
2H²⁺(aq) + SO₄²⁻(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + Ca²⁺(aq) + SO₄²⁻(aq)
Net ionic equation:
2H²⁺(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + Ca²⁺(aq)
Explanation:
Chemical equation:
H₂SO₄(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + CaSO₄(aq)
Balanced chemical equation:
H₂SO₄(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + CaSO₄(aq)
Complete ionic equation:
2H²⁺(aq) + SO₄²⁻(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + Ca²⁺(aq) + SO₄²⁻(aq)
Net ionic equation:
2H²⁺(aq) + CaCO₃(s) → H₂O(l) + CO₂(g) + Ca²⁺(aq)
Kg=24,590550 g=24590,550 mg=24590550
