The correct answer is - tropical wet.
The tropical wet climate conditions are the ones that will enable the quickest chemical weathering of the granite, sandstone, and shale. That is due to the constant heat, high humidity, and daily rain pours.
Hope this helps :D
Answer:
A. The number of atoms of each element is the same on the reactant side as the product side.
Explanation:
The equation demonstrates the law of conservation of mass in such a way that the number of atoms of each element is the same on the reactant side as the product side.
According to the law of conservation of mass "matter is neither created nor destroyed in a chemical reaction but they are changed from one form to another".
- By virtue of this, the number of moles of atoms on both sides of the expression must be the same.
To determine the formula mass of beryllium chloride, BeCl₂, we start up with the basis of one mole first.
Basis: 1 mole BeCl₂
To determine the molar mass of BeCl₂, we add up the mass of one mole of beryllium and two moles of chlorine.
1 mol Be = 9 g/mol
1 mol of Cl = 35.45 g/mol
Solving,
molar mass of BeCl₂ = (1 mol Be)(9 g/mol) + (2 mols Cl)(35.45 g/mol)
molar mass of BeCl₂ = 79.9 g
Then, we take into consideration that 1 mol is equal to 6.022 x 10²³ formula units.
formula mass BeCl₂ = (79.9 g/mol)(1 mol/6.022 x 10²³ formula units)
formula mass of BeCl₂ = 1.33 x 10⁻²² g/formula unit
<em>Answer: 1.33 x 10⁻²² g/formula unit</em>
Answer:
The high system pressure and relatively large chlorine molecule size.
Explanation:
Having the expression of the ideal gas, and clearing the pressure, we have:
P = nRT/V
Meanwhile, for a non-ideal gas we have the following equation:
P = (nRT / V-nb) - n2a/V2
In this equation, high pressures and low temperatures have an influence on nonideal gases.
Therefore, at high pressures, the molecules in a gas are closer together and have high intermolecular forces. On the other hand, at low temperatures, the kinetic energy of a gas is reduced, so that the intermolecular attractive forces are also reduced.
