Answer:
0.67moles
Explanation:
The balanced equation of the chemical reaction given in this question is:
N2 + 3H2 → 2NH3
According to this equation, 3 moles of hydrogen gas (H2) produces 2 moles of ammonia gas (NH3)
Therefore, 1 mole of hydrogen gas (H2) will produce;
= 1 × 2/3
= 2/3
= 0.6666
= 0.67moles of ammonia (NH3)

cellular respiration than yeast that is given less sugar?
Answer:
True
Explanation:
Cellular respiration is a metabolic pathway that allows cells to take apart food molecules and use their atoms as an energy source. This pathway takes electrons from food molecules and transfers them to oxygen, has energy transferred to ATP and arranges molecules into water, carbon dioxide and waste.

Microorganisms have a major role in maintaining soil biodiversity. They recycle nutrients in ecosystems and decompose organic matter in soil. Organic matter contains dead and living plant and animal materials. Microorganisms convert these materials into simpler compounds that maintain soil quality and help with plant growth.
Which solution could best help to restore or increase microorganisms and soil biodiversity?
A.
adding manure or compost to the soil
B.
spraying chemical weed-killers and fertilizers on the soil
C.
removing all ground-covering plants from the soil
D.
adding sewage containing synthetic materials to the soil
Answer:
A i think
Explanation:
The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.
What are microorganisms?A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
“Microorganisms are minute organisms that are invisible to the normal eye.” Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.
Given options are-
A. adding manure or compost to the soil
B. spraying chemical weed-killers and fertilizers on the soil
C. removing all ground-covering plants from the soil
D. adding sewage containing synthetic materials to the soil
Therefore, The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

Explanation:
However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results. The two explanations work like different languages that express the same thing.

How do the mass number and atomic change as a particle goes through beta decay
Answer:
The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

A. Body systems are like computer programs that have to communicate with each
other in order to make the computer work.
B. Body systems are like runners in a marathon who each run alone and don't need the
other runners to finish the race.
C. Body systems are like machines with many different moving parts.
D. Body systems are like individual parts of one big story.
Answer:
the answer would be b
Explanation:
the body sytsem needs to depend on eah other in order to work
Body systems are like runners in a marathon, who each run alone and don't need the other runners to finish the race, is not a good way to describe a body system, hence option B is correct.
How body systems work together?Your digestive tract takes nutrients and water from the food you eat in to your body. The body's cells receive oxygen, water, and nutrients through your circulatory system.
Your skin, excretory system, and respiratory system all function to remove wastes from your cells.
Your body's many systems depend on one another to function properly. While your heart's muscles require oxygen from your lungs to beat, your respiratory system depends on your circulatory system to distribute the oxygen it collects.
Therefore, option B is correct.

molecular mass meaning in chemistry?
Answer:
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
Explanation:
The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Hence why Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
What is the formula for pH?
Answer:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

Explanation:
what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)
In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
What is balanced equation ?A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.
Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.
The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars
Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
