C. Liquid. The Earth is mostly water, namely ocean water which is liquid.
Answer:
V₂ = 8.36 L
Explanation:
Given data:
Initial volume of gas = 5.00 L
Initial temperature = -50.0°C (-50 + 273 = 223 k)
Final temperature = 100°C (100+273 = 373 k)
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 5.00 L × 373 K / 223 K
V₂ = 1865 L.K / 223 K
V₂ = 8.36 L
Answer: 8 valence electrons
Explanation:
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
I think it might be D or B
And my other two might be A or C
