A molecule of a compound is composed of at least two types of atoms.
Explanation:
A molecule is defined as when two or more atoms of an element combine together by the bonds by sharing the electrons as O^2 (oxygen molecule)
A compound is a molecule when two different types of atom joined by chemical bonds as covalent, ionic or coordinate bonds as NH^3 ( ammonia)
Answer:
bonding capacity is based on the oxidation number. the pattern throughout families 1-2 and 13-18 is 12343210. depending on wether the elements in a family lose or gain 1-4 valence electrons is what determines the bonding capacity. for example, the elements in family one, or the Alkali family elements, lose one valence electron to become stable. this means the next outer shell has 8 valence electrons and is therefore stable. family two elements lose 2 valence electrons in order to have 8 on the outer shell. family thirteen elements lose 3 valence electrons. family fourteen can either lose or gain their four valence electrons as long as they end up with an outer shell with 8 valence electrons. family fifteen gains 3 valence electrons, 16 gains two, and 17 gains 1. family 18 doesn't lose or gain any since it is already stable. if an element loses valence electrons its oxidation number will be a positive 1,2,3, or 4. if an element gains valence electrons its oxication number will be a negative 1,2,3, or 4. the pattern of oxidation numbers is the same as the bonding capacity and it is +1,+2,+3,+4/-4,-3,-2,-1 or 0. basically if you can find the oxidation number then you can find the bonding capacity

what!!! I don't know whats that u talking about
Answer
find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically
n=m/M is the equation to use to get moles here
30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so
0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm
then divide the actual by the theoretical to get the % yield which is 83.6%
