Answer:
See below.
Explanation:
CH4 + 2 O2 → CO2 + 2H2O
One molecule of methane reacts with 2 molecules of oxygen to produce one molecule of carbon dioxide and two molecules of water.
It is also true if we replace the word molecule by mole.
Answer:
4 moles of HCl are produced.
Explanation:
Given data:
Mass of hydrogen = 4 g
Number of moles of HCl = ?
Solution:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 4 g/2 g/mol
Number of moles = 2 mol
now we will compare the moles of hydrogen and HCl.
H₂ : HCl
1 : 2
2 : 2/1×2 = 4 mol
Thus, 4 moles of HCl are produced.
Bc the time changes that is the answer hoped i helped

Answer: 1) only a salt and water
An acid and base reacts together to undergo neutralization to form salt and water.
where HCl is an acid and NaOH is a base to form salt (NaCl) and water 
.
Answer: 2) The formula of the hydrogen ion is often written as 
.
All acids dissociate in water to give ions.
Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.
Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.
Answer: 4) A conjugate acid base pair transfers hydrogen ion.
Here 
accepts a proton and thus act as a base and the corresponding 
is its conjugate acid.
Answer: 5) Bronsted Lowry acid is a substance that donates protons. Bronsted Lowry base is a substance that accepts protons.
and 
is a acid which accepts proton and thus acts as base to form conjugate acid .
