Explanation:
Answer:
Compounds 1 and 2 are not the same
Explanation:
To solve this question we need to find the molecular formula of the compounds converting the mass of each atom to moles. Molecular formula is defined as the simplest whole number ratio of atoms present in a molecula:
Compound 1:
<em>Moles Tin: </em>
5.63g Sn * (1mol / 118.7g) = 0.04743 moles
<em>Moles Cl:</em>
3.37g Cl * (1mol / 35.45g) = 0.09506 moles
Ratio Cl:Sn
0.09506 moles / 0.04743 moles = 2
Molecular formula SnCl₂
Compound 2:
<em>Moles Tin: </em>
2.5g Sn * (1mol / 118.7g) = 0.02106 moles
<em>Moles Cl:</em>
2.98g Cl * (1mol / 35.45g) = 0.08406 moles
Ratio Cl:Sn
0.08406 moles / 0.02106 moles = 4
Molecular formula SnCl₄
Compounds 1 and 2 are not the same because molecular formulas are different.
Answer:
47 L will be the volume STP
Explanation:
Answer: 4.35%
Explanation:
Scientists estimate that the current composition of gases in the Earth's atmosphere has been stable for the last 200 million years or so.
If the Earth was formed 4,600 million years ago then the percentage of her age that the atmosphere has been in its composition is:
= 200 / 4,600 * 100%
= 4.35%
Yep ur right it’s b as it is balanced
