Answer:

Theoretical 32.04 g

The precent yeild 87. 39 %

Explanation:

Mole of H2 = m/mw = 4/2 = 2 mol

From the equation

1 mol H2 --> 1/2 mol CH3OH

2 mol H2 -->??

So we have 1 mol Ch3oh

Mass of Ch3oh = mole *Mw = 1* 32.04

= 32.04g >>> the theoretically

For percent yeild = actual / theoretical * 100%

( 28.0/32.04) *100% =

87.93%

The reactions that will take place will generate Zinc salts that will taint the food. Excessive levels of these salts can cause sickness, so it is very important to ensure food hygiene standards are met by keeping acidic foods away from damaging materials like zinc that will erode and get into the food.

Use Lewis diagrams to show how electrons are shared to form covalent bonds in compounds wit the following atoms. Write the formu
bixtya [17]
The Lewis structure/diagram for CH2O (aka Formaldehyde) can be written in either of the following ways shown in the picture.
The dots represent electrons in the valence shell of the atom (the outermost shell). The green dots are electrons that belong to the Oxygen atom, the blue belong to the Carbon atom, and the pink belong to the Hydrogen atoms.
Covalent bonds are bonds between atoms where atoms share electrons with each other. Atoms bond because they obey the octet rule ( the rule states that most atoms of main-group elements tend to want 8 electrons in their valence shells). 
Oxygen has 6 valence electrons, Carbon has 4, and Hydrogen has 1. H does not follow the octet rule, but C and O do, so the atoms are arranged in this way so that the O and C atoms have a full octet of electrons in their valence.
