The following reaction produces ethanoic acid (chacooh) from methanol (ch3oh) and carbon
monoxide
chcooh
ch3oh + co
relative atomie mass: h = 1: 0 = 16; c = 12
calculate the maximum mass of ethanoic acid that can be produced from 160g methanol,
assuming the carbon monoxide is in excess.

Explanation:

We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

M_r:         32                          60

           CH₃OH + CO ⟶ CH₃COOH

m/g:        160

(a) Moles of CH₃OH

(b) Moles of CH₃COOH

(c) Mass of CH₃COOH

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
