Answer:
1.14 × 10³ mL
Explanation:
Step 1: Given data
- Initial volume of the gas (V₁): 656.0 mL
- Initial pressure of the gas (P₁): 0.884 atm
- Final volume of the gas (V₂): ?
- Final pressure of the gas (P₂): 0.510 atm
Step 2: Calculate the final volume of the gas
If we assume ideal behavior, we can calculate the final volume of the gas using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 0.884 atm × 656.0 mL/0.510 atm = 1.14 × 10³ mL

Answer:
4.90 moles of
will produce (9.8) moles of
,
(4.90) moles of
and
(39.2) moles of 
Explanation:
From the question we are told that
The number of moles of is 
The formation reaction of
is
From the reaction we see that
1 mole of
is formed by 2 moles of
1 mole of
and 4 
This implies that
4.90 moles of
will produce (2 * 4.90) moles of
,
(1 * 4.90) moles of
and
(8 * 4.90) moles of 
So
4.90 moles of
will produce (9.8) moles of
,
(4.90) moles of
and
(39.2) moles of 
adhesion refers to the tendency of unlike molecules to bond with one another
Answer:
Empirical formula is CCl₄
Explanation:
Given data:
Percentage of carbon = 7.70%
Percentage of chlorine = 92.3%
Empirical formula = ?
Solution:
Number of gram atoms of Cl = 92.3 / 35.5 = 2.6
Number of gram atoms of C = 7.70 / 12 = 0.64
Atomic ratio:
C : Cl
0.64/0.64 : 2.6/0.64
1 : 4
C : Cl = 1 : 4
Empirical formula is CCl₄.
