Answer: B
Explanation: since the balloon is getting bigger it would make sense for the volume to increase ( get bigger) when volume increases the pressure decreases
C. the sun is continuously releasing energy.
Answer:
V1 / T1 = V2 / T2
V₁ = 420 mL
T₁ = 210 K
V₂ = ?
T₂ = 250 K
420 / 210 = V2 / 250
V2 = (420 / 210) x 250 = 500 mL
Explanation:
Answer: 800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
Explanation:
Volume of the methyl alcohol = x
Volume of water = y = 200 mL
Volume of the solution ,V = x + y
Volume percentage of solution = 80%
x = 800 mL
800 mL of methyl alcohol should be added to 200 ml of water to make this solution.
Answer:
2Al + 3Cu(ClO3)2 → 2Al(ClO3)3 + 3Cu and
3Ag + Li3PO4 → Ag3PO4 + 3Li
Explanation:
In single repacement reactions, one element is substituted for another to produce a different compound. In the problem, the cation is exchange and the elements produced are:
Al(ClO3)3 and Ag3PO4.
The reactions are:
<h3>2Al + 3Cu(ClO3)2 → 2Al(ClO3)3 + 3Cu</h3>
And:
<h3>3Ag + Li3PO4 → Ag3PO4 + 3Li</h3>
