The most obvious answer for this would be a product i think.
Answer:
Number of mole = 5moles
Explanation:
To find the number of mole of methane,we will use the formula
n = m/ Mm
n - moles
m - mass
Mm - molar mass
Since m - 80g
Let's calculate the molecular weight of CH4
C - 12
H - 1
Mw = 12 + 1 * 4
= 12 + 4
= 16g/mol
n = 80g/16g/mol
n = 5moles
Answer:
C The water accepts a proton from the hydrogen chloride.
Explanation:
The equation given in this question where hydrogen chloride reacts with water is as follows:
HCI + H2O → CI- + H3O+
From this equation, hydrogen chloride (HCl) loses or donates hydrogen ion (H+) or proton to water (H2O), which accepts it to become hydronium ion. Hence, in a nutshell, water (H2O) accepts a proton (H+) from the hydrogen chloride (HCl) in this reaction.
