Answer:
This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:
Explanation:
P = 3.00 atm + 2.80 atm + 0.25 atm + 0.15 atm
P = 6.8 atm
3.5 atm = x (6.8 atm)
x = 0.51
Except for the Middle East :)
Answer: 2800 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
Given mass = 5 kg = 5000 g
1 mole of 
produces = 1 mole of 
50 moles of produces =
of
Mass of 
2800 g of is produced from 5.0 kg of limestone.
The sentence best describes the shapes of the moon over the course of about a month is over the course of about a month, the shape of the moon changes from a full circle, to a crescent, and back to a full circle.
<h3>What is full moon?</h3>
The moon when looks like a full circle and having the highest brightness over its life cycle is called the full moon.
The full moon, crescent, half moon or no moon are all the stages of a Moon's lifecycle.
Over a period of 14 days, moon changes from a full moon to no moon. In the another 14 days, no moon changes to full moon. This cycle keeps on going for years and years.
Thus, the sentence best describes the shapes of the moon over the course of about a month is over the course of about a month, the shape of the moon changes from a full circle, to a crescent, and back to a full circle.
