Explanation:
What is the volume of 1. 5 moles of oxygen gas at standard temperature and pressure (STP)? 22 L 34 L 58 L 71 L.
Volume is the quantity of area occupied by any substance in a system and is measured in litres. The volume of oxygen at STP will be 34 L.
What is STP?STP is the standard temperature and pressure of the substance that is used for the calculation of the gases for the comparison.
The moles of oxygen given is 1.5 moles and as we know that 1 mole of gas at STP has 22.4 L of volume then the volume of 1.5 moles containing oxygen will be,
[tex]1.5 \times 22.4 = 33.6 \;\rm L[/tex]
Therefore, option B. 34 L is the volume of 1.5 moles of oxygen at STP.

A gas has a volume of 87.5 L and 8.7 moles. if the amount of moles is increased to 18, what is the volume?
Answer:
V2 = 181
Explanation:
Follow this equation: V1/n1 = V2/n2
V1 = 87.5L
n1 = 8.7
n2 = 18
V2 =?
V1/n1 = V2/n2 (to find V2, switch n2 to the other side)
So it going to be ---> n2×V1/n1 = V2
18×87.5/8.7 = V2
1575/8.7 = V2
181 = V2
So the answer is: 181
Consider this reaction: NH4 HPO42− → NH3 H2PO4− Which is the Bronsted-Lowry acid ? NH4 HPO42- HPO42– H2PO4–.
Bronsted - Lowry acid in the given reaction is NH₄, as it gives H⁺ ion.
What is Bronsted - Lowry acid?According to the theory of Bronsted - Lowry, acids are those substances which gives H⁺ ion or proton in the aqueous medium.
Given chemical reaction is :
NH₄ + HPO₄²⁻ → NH₃ + H₂PO₄⁻
In the above reaction NH₄ is the Bronsted - Lowry acid as it gives H⁺ ion in the reaction and changes to NH₃ which is the conjugate base of NH₄. Whereas HPO₄²⁻ is the Bronsted - Lowry base as it accepts the H⁺ ion to form H₂PO₄⁻ which is the conjugate acid of it.
Hence, option (1) is correct, i.e. NH₄ is the Bronsted - Lowry acid.

Answer:
option (b)
Explanation:
A gases can be compressed much more than a solid or liquid because the particles of a gas are very far apart
Does q for the formation of 1 mol of no from its elements differ from q for the decomposition of 1 mol of no to its elements and what is the relationship between the two qs?.
Answer:
Yes, the Qs for the two reactions are reciprocal.
Explanation:
No, the Qs are the same.
What are decomposition and examples?Decomposition reactions are processes in which chemical species break up into simpler parts. Usually, decomposition reactions require energy input. For example, a common method of producing oxygen gas in the laboratory is the decomposition of potassium chlorate (KClO3) by heat.
How do elements decompose?When bonds in a single chemical compound are broken, it results in it breaking apart to form two or more products. When this happens, it is known as chemical decomposition and it takes place as a chemical reaction.

What do we have to have to be able to determine the number of neutrons?
A. average atomic mass
B. mass number
Answer:
Answer is A :)
Explanation:
Answer:
B. Mass number
Explanation:
In order to gain the number of neutrons you need to subtract the Protons from the atomic mass (also known as the mass number or nucleon number.
For example :
Carbon - protons= 6
Nucleons=12
Therefore carbons neutrons = 6

A 2.0 mol sample of CO(g) and a 2.0 mol sample of H2O(g) are introduced into a previously evacuated 100. L rigid container, and the temperature is held constant as the reaction represented above reaches equilibrium.
CO(g) + H2O (g) CO2(g) + H2(g) Kc = 1.5 x 10^3
Which of the following is true at equilibrium?
For the chemical reaction CO(g) + H2O (g) >>CO2(g) + H2(g) at Kc = 1.5 x 10^3 the solve to discover
CO2= 1.94>>CO= 0.06 is True about the reaction
What is true about the reaction?
Generally, the equation for the Chemical Reaction is mathematically given as
CO(g) + H2O (g) >>>CO2(g) + H2(g)
Therefore
Kc = x .x / ( 2 - x ).(2 - x)
Kc= 1.5 x 103
Kc= x2 / (2-x)2
Where
Kc = 1.5 x 103
x=1.94
In conclusion,
[CO] = [H2O]
CO= 2 - 1.94
CO= 0.06
[CO2] = [H2]
CO2= x
CO2= 1.94

Why is it more comfortable to exercise on a day when the relative humidity is low?
Sweat evaporates quickly at low relative humidity, the amount of water vapor in the atmosphere, so it makes the body feel cooler. If the humidity is high that means there is a lot of water vapor in the air and thus the sweat cannot evaporate and forms pools on our skin making us feel uncomfortable.
