CaCO₃ → CaCl₂
Ca = 40, C = 12, O = 16, Cl = 35.5
100 →111
3     →  x
x = 3.33g

What is the pressure in a 24.0-LL cylinder filled with 32.7 gg of oxygen gas at a temperature of 319 KK? Express your answer to
Blizzard [7]

Answer:

The pressure in that cylinder = 1.12atm

Explanation:

We use general gas law to calculate it. General gas law is gotten by combining Boyle's law, Charles' law and Avogadro's law. Thus

P = nRT/V

Where n = number of moles

R = the gas constant

T is the Temperature, V is the volume and P is the pressure.

Given: T = 319K, V = 24L, R = 0.0821 L.atm/K.mol

The first step is to find n using

n = mass of O2/molar mass of O2

=32.7/32

=1.0219

Now, using P =nRT/V

P = 1.0219 ×0.0821×319÷24

Therefore P = 1.12atm

How do helpful variations increase in a species over time?
Vladimir [108]

Answer:

through natural selection

Explanation:

Natural selection is the driving mechanism of the evolution of species. Organisms can survive more in an environment if they are capable to adapt the changing environmental conditions. After surviving they are also able to pass their modified trait into their future generations (evolution).

Helpful variations accumulate through natural selection, as the organisms that are better adapted to their environment reproduce offspring with the same variations.

What must break in order for water to change from solid to liquid to gas?
pogonyaev
When changing states, only the intermolecular forces are considered, which, in water's case are hydrogen bonds. In order to go from solid to liquid to gas, the hydrogen bonds between the water molecules must be weakened to a certain degree that allows the molecules to spread further apart in liquids, and must be broken altogether to separate the molecules in order to turn it into gas.
Therefore, the answer is d.

The reason it is not the covalent bonds within molecules (despite the fact that it will turn water into a gas, it’s not water vapour, but hydrogen and oxygen gas) is that when bonds within a molecule are broken, this is called decomposition and it is a CHEMICAL change. Changing states is only a PHYSICAL change.
It is not ionic because water has covalent bonds.
Hydrogen bonds can only occur BETWEEN molecules (intermolecular forces).
Covalent bonds can only occur WITHIN molecules (intramolecular).
