Answer : The moles ratio between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.
Explanation :
The balanced chemical reaction will be,
Mole ratio : It is defined as the ratio of the number of moles of the substances whose ratio is to be calculated.
In a chemical reaction, the stoichiometric coefficients represents the number of moles.
By stoichiometry of the reaction we can say that,
1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia gas.
Hence, the mole ratio of between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.
For instance you have a chemical reaction of N2 + 3H2 -> 2NH3. The number of moles of N2 is 1, H2 is 3 and NH3 is 2. The mole to mole ratio between nitrogen gas and hydrogen gas is 1/3 or 1 is to 3.
We can see here that some common uses of nitric acid:
Nitric acid is a highly corrosive and strong mineral acid. It is a clear or yellowish liquid that is commonly used in various industrial, laboratory, and chemical applications.
In its pure form, nitric acid is a colorless liquid, but it can have a yellowish tint due to the presence of nitrogen dioxide, which forms when nitric acid reacts with air.

Answer: Nitric acid is used in the production of ammonium nitrate and calcium ammonium nitrate which find applications as fertilizers. Ammonium nitrate is also used in the manufacturing of urea ammonium nitrate (UAN) used in fertilizer formulations and also as explosives.

The radioactive isotope of the element with unstable energy in the nucleus is called a radioisotope. Neon with atomic mass 19 particlehas charge +1 and mass 0.
When a radioactive element undergoes decay they emit some types of particles like alpha, beta, or positron particles. The alpha particle has a +2 charge and a mass number of 4.
The beta particle has a -1 charge and a mass number of 0, while the positron has a particle charge of +1 and a mass number of 0.
In the decay of the Neon element, the positron is emitted can be shown as:
Therefore, option 3. atom emits positron particle.

Answer: The correct answer is option 3.
Explanation: There are three types of particles that are emitted when a radioisotope undergo decay process:
1. Alpha particle: This particle is emitted when a radioisotope undergoes alpha decay process. The charge on the particle is +2 and mass number is 4.
2. Beta-particle: This particle is emitted when a radioisotope undergoes beta-minus decay process. The charge on the particle is -1 and mass number is 0.
3. Positron particle: This particle is emitted when a radioisotope undergoes beta-plus decay process. The charge on the particle is +1 and mass number is 0.
For the given options undergoing decay processes:
Option 1:
It emits beta-particle.
Option 2:
It emits beta-particle.
Option 3:
It emits positron-particle.
Option 4:
It emits alpha particle.
Hence, the correct option is Option 3.
B) oxygen, glucose
C) carbon dioxide, oxygen
D) oxygen, carbon dioxide
The answer is C) carbon dioxide, oxygen.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
So lets eliminate some answers:
Oxygen can not convert itself to glucose and plants don't take in oxygen so this answer is automatically eliminated
Plants take in carbon dioxide and convert it to oxygen basically how humans breath but inverted, not the other way around.
Glucose naturally is not found in the atmosphere in the first place so if a plant were to survive is would have to be in a glucose enriched environment which is very uncommon meaning it would be very rare to be a living functional plant that can photosynthesize. So this is checked off the list!
So we are now left with one sentence that would make sense
Plants take in carbon dioxide meaning the first section of this answer is right and they release oxygen which is also correct therefore this statement is valid and is the correct answer
Hope this helped (:

Answer:
D. 27 13 Al
Explanation:
13 protons means atomic number 13. The periodic table says element 13 is aluminum (Al). 27 is the atomic mass, made up of 13 protons (1 each) and 14 neutrons (also 1 each) for a total of 27 atomic mass.
Answer:
[H⁺] = 10⁻¹²
It could be the strongest base.
Explanation:
The base is considered to be of highest strength if it has least hydrogen ion concentration or high hydroxide ion concentration.
Generally a stronger base gives more hydroxide ion concentration.
the relation between hydrogen ion and hydroxide ion concentration is
[H⁺][OH⁻]= 10⁻¹⁴
[OH⁻] = 10⁻¹⁴ / [H⁺]
a) [H⁺] = 10⁻⁹
[OH-] = 10⁻⁵
b) [H⁺] = 10⁻¹¹
[OH-] = 10⁻³
c) [H⁺] = 10⁻¹⁰
[OH-] = 10⁻⁴
d) [H⁺] = 10⁻¹²
[OH-] = 10⁻²
This the highest concentration of hydroxide ion in the given choices so it could be the strongest base.
