answer is B
because both sides have equal numbers of atomos
Answer:
The force of gravity is inversely related to the distance the alien is from Earth; this means that force of gravity decreases as the distance between the alien and Earth increases. As the distance between the alien and the surface of the planet increases, the force of gravity decreases.

Answer:
0.79 g
Explanation:
Let's introduce a strategy needed to solve any similar problem like this:
- Apply the mass conservation law (assuming that this reaction goes 100 % to completion): the total mass of the reactants should be equal to the total mass of the products.
Based on the mass conservation law, we need to identify the reactants first. Our only reactant is sodium bicarbonate, so the total mass of the reactants is:
We have two products formed, sodium carbonate and carbonic acid. This implies that the total mass of the products is:
Apply the law of mass conservation:
Substitute the given variables:
Rearrange for the mass of carbonic acid:
Answer:
The answer to your question is below
Explanation:
Data
Volume 1 = V1 = 3000 l
Temperature 1 = T1 = 30°C
Pressure 1 = P1 = 99 kPa
Volume 2 = ?
Temperature 2 = T2 = 16°C
Pressure 2 = P2 = 45.5 kPa
Process
1.- To find the new volume we need to convert the temperature to °K
T1 = 30 + 273 = 303°K
T2 = 16 + 273 = 289°K
2.- Use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve it for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (99 x 3000 x 289) / (303 x 45.5)
-Result
V2 = 85833000 / 13786.5
V2 = 6225.8 l
There are no conversion factor ratios.
