<u>Answer:</u> The volume of oxygen gas required is 3.75 mL
<u>Explanation:</u>
STP conditions:
1 mole of a gas occupies 22.4 L of volume.
We are given:
Volume of ammonia reacted = 3.00 mL = 0.003 L (Conversion factor: 1 L = 1000 mL)
The chemical equation for the reaction of ammonia with oxygen follows:
By Stoichiometry of the reaction:
(4 × 22.4) L of ammonia reacts with (5 × 22.4) L of oxygen gas
So, 0.003 L of ammonia will react with = 
of oxygen gas
Hence, the volume of oxygen gas required is 3.75 mL

Explanation:
Some genetic mutations, like being able to drink milk are beneficial. While others, like sickle cell anemia. I know you didn’t ask, but it’s just for future reference.
Answer:
The moles of KClO3 = 0.052 moles
Explanation:
Step 1: Calculate the pressure of oxygen gas
The oxygen has a total pressure (including water vapour) of 760 mmHg
The pressure of Oxygen = (760 - 26) mmHg
= 734 mmHg of water vapor
Step 2: Calculate the no of moles of oxygen
Using Ideal gas equation
P V = n R T
P = pressure of oxygen in N/m2 ( you should convert 734 mmHg to pascal or N/m2) = 97,858.6 N/m2 or pas
V = 2 litres = 0.002 m3
R = gas constant = 8.31
T= 27oC = 300 K
Applying this equation P V = n R T
97,858.6 x 0.002 = n x 8.31 x 300
n = 0.0785 mol of Oxygen
From the balanced equation
2 KClO 3 ---- 2 KCl + 3 O 2
3 moles of oxygen is produced from 2 moles KClO3
so 0.0785 mole of oxygen will be produced from x
x = (0.0785 x 2 ) / 3
x = 0.052 moles of KClO3
3) - different volumes

Answer:
1) Monochrome
2) Monocot
3) Monosaccharide
4) Monounsaturated
5) Monoxide
Explanation:
The prefix mono or mon is of Greek origin and it means single, lone or one.
From the meaning of the words we can tell that they have something in common:
1) Monochrome: This refers to an artwork, a painting or drawing that has just one color.
2) Monocot: This is a type of flowering plant that has a single embryo and a single cotyledon.
3) Monosaccharide: This is a type of simple sugar that contains one sugar unit that cannot be split.
4) Monounsaturated: This refers to a molecule that contains one double or triple bond.
5) Monoxide: This refers to a form of oxide that contains only one oxygen atom.
From the definitions above, all the words mean having only one or a single item.
That is what they have in common.
