80.5%- The total mass of the compound is 18g (14.5 + 3.5) then divide the mass of magnesium by the total. easy way to remember is- (part/whole) x 100
At a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.
<h3>
Behavior of gases at low pressure and high pressures</h3>
At low pressure, the distance between gas molecules is relatively far apart, but as the pressure of the gas increases, the distances between theses gaseous molecules becomes smaller.
Due to the high pressure the volume occupied by the gas molecules becomes significant compared with the volume of the container.
As a result, the total volume occupied by the gas will be greater than the volume predicted by the ideal gas law.
Thus at a very high pressure, the volume of occupied by a real gas is greater than the volume predicted by the ideal gas law, because the volume of the actual particles is more significant under high pressure.

The type of chemistry that allows the anthropologist to find out the nature of the substance in a mummy's wrap would be analytical chemistry. It is a branch of chemistry which deals with obtaining and processing information pertaining to the composition and the structure of the subject in question. It deals with apparatus and techniques to identify, separate and quantify a substance. It is the science of the determination of a substance and how much is present. By the analytical techniques, the anthropologist could hypothesize what is the substance of the wrap and its physical and chemical properties.
Answer:
The molarity of the new solution is 0.72 M
Explanation:
Step 1: Data given
Volume of the original solution = 360 mL =.360 L
Molarity = 0.87 M
We add 75 mL = 0.075 L
Step 2: Calculate moles
Moles = molarity * volume
Moles = 0.87 M * 0.360 L
Moles = 0.3132 moles
Step 3: Calculate new molarity
The number of moles stays constant
Molarity = moles / volume
Molarity = 0.3132 moles / (0.36+0.075)
Molarity = 0.3132 moles / 0.435 L
Molarity = 0.72 M
The molarity of the new solution is 0.72 M
Answer:
Oxygen is the component of air necessary for life on Earth. All living organisms require it for respiration.
