Explanation: Number of moles of water = mass of water/ molar mass.
Molar mass of H2O = (1*2) + 16 = 18.0
Now we only need to calculate the number of moles of water.
The chemical reaction is as follows
CH4 + 2O2 ---> CO2 + 2H2O
From the eqn, the moles of H2O = 2*moles of CH4
Molar mass of CH4 = 12 + 4 = 16. Number of moles of methane = mass/
molar mass. No of moles = 6.4/16 = 0.4. So the number of mole of water = 2* 0.4 = 0.8. We already calculate its molar mass earlier. So mass of water = molar mass * number of moles = 18 * 0.8 = 14.4
Answer:
A base is a substance that can donate a hydroxide ion.

That would be the proton. The number of protons in the nucleus determine which element it is and its properties.
Explanation:
Equation of reaction:
PCl₅ ⇆ PCl₃ + Cl₂
Problem: what direction will the reaction shift towards if PCl₃ is added;
Solution:
According to Le Chatelier's principle "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
If the concentration of PCl₃ is increase, the equilibrium will shift towards the left because it is used up in that direction. More of the PCl₅ will be produced in order for the system to adjust back to equilibrium.
