Answer:
7.22 L
Explanation:
From the question,
Applying Charles law,
V₁/T₁ = V₂/T₂...................... Equation 1
Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin
Make V₂ the subject of the equation
V₂ = (V₁×T₂)/T₁................. Equation 2
Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K
Substitute these value into equation 2
V₂ = (5.00×423)/293
V₂ = 7.22 L
This is true, " To increase acceleration of an object, you reduce its MASS or increase the applied force."
The amount of heat (in calories) needed to raise the temperature is 324.885 calories
<h3>How to determine the temperature change </h3>
We'll begin by obtaining the temperature change. This can be obtained as followed:
- Initial temperature (T₁) = 14 °C
- Final temperature (T₂) = 25 °C
- Change in temperature (ΔT) = ?
ΔT = T₂ - T₁
ΔT = 25 - 14
ΔT = 11 °C
<h3>How to determine the heat (in Calories)</h3>
The amount of heat needed to raise the temperature can bee obtaimedals follow:
- Mass (M) = 33 g
- Change in temperature (ΔT) = 11 °C
- Specific heat capacity (C) of diethyl ether = 0.895 cal/g°C
- Heat (Q) =?
Q = MCΔT
Q = 33 × 0.895 × 11
Q = 324.885 calories
Thus, the amount of heat needed is 324.885 calories

Answer:
Hydrogen-1
Explanation:
Not sure what kind of explanation is needed for your question, because it doesnt specify.
The easiest should be:
Average mass of an element is calculated as the sum of the multiplication of each isotope by its percentage
And the mass of the hydrogen is 1, therefore the more abundant is hydrogen-1
