The mass of ammonia that would be produced is 312.5 g
First, we will write a balanced chemical equation for the reaction
The balanced chemical equation for the reaction is
3H₂(g) + N₂(g) → 2NH₃(g)
This means
3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia.
First, we will determine the number of moles of each reactant present
For Hydrogen (H₂)
Mass = 83.6 g
Molar mass = 2.016 g/mol
Using the formula
[tex]Number\ of\ moles = \frac{Mass}{Molar\ mass}[/tex]
Number of moles of H₂ present = [tex]\frac{83.6}{2.016}[/tex]
∴ Number of moles of H₂ present = 41.468254 moles
For Nitrogen (N₂)
Mass = 257 grams
Molar mass = 28.0134 g/mol
∴ Number of moles of N₂ present = [tex]\frac{257}{28.0134}[/tex]
Number of moles of N₂ present = 9.174181 moles
Since,
3 moles of hydrogen gas reacts with 1 mole of nitrogen gas to produce 2 moles of ammonia
Then,
27.522543 moles of hydrogen gas will react with the 9.174181 moles of nitrogen gas to produce 18.348362 moles of ammonia
∴ 18.348362 moles of ammonia will be produced during the reaction
Now, for the mass of ammonia that would be produced
From the formula
Mass = Number of moles × Molar mass
Molar mass of ammonia = 17.031 g/mol
Mass of ammonia that would be produced = 18.348362 × 17.031
Mass of ammonia that would be produced = 312.49095 g
Mass of ammonia that would be produced ≅ 312.5 g
Hence, the mass of ammonia that would be produced is 312.5 g

What evidence is there to support the theory that strong nuclear force is greater than electromagnetic force?
A: Electrons are attracted to protons.
B: Protons repel other protons.
C:The nucleus holds the protons together.
D:Protons and neutrons are attracted to each other.
Answer:
The electromagnetic force is a long range force which acts of charged particles. Like charges repel and unlike charges attract. ... The strong nuclear force is very short range and can only bind adjacent protons and neutrons. The electromagnetic force is long range.

If you weighed the atoms that appear on the reactant side of the equation, would they have the same mass as the atoms that appear on the product side?
Answer:
Yes,they will have the same mass.
Explanation:
According to law of conservation of mass:
'Mass can neither be destroyed nor be created during a chemical reaction'
In a balanced chemical reaction :
Total numbers of atoms on the reactants side are always equal to the total numbers of atoms on the product side.
Total mass of the atoms on the reactant side of the equation is always equal to the total mass of atoms on the product side.
For example:
Number of atoms on reactant side =
=(2)2 Hydrogen atoms + (1)2 Oxygen atoms = 6 atoms
Number of atoms on the product side =
=(2)((2 Hydrogen atoms) + (1 Oxygen atoms)) = 6 atoms
Mass of of reactants = (2)(number of hydrogen atoms)(mass of hydrogen atom) + (1)(number of oxygen atoms)(mass of oxygen atoms)
= (2)(2)(1u)+(1)(2)(16u) = 36u
Mass of products = 2((number of hydrogen atoms)(mass of hydrogen atom)+(number of oxygen atoms)(mass of oxygen atom))
= 2((2)(1u)+(1)(16u)) = 36u
Mass of of reactants = Mass of products = 36u

Answer: It will increase the rate of reaction
Explanation:
An increase in enzyme or substrate concentration will increase the rate of reaction.
What is an enzyme?An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.
Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off.
The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme.
Hence, an increase in enzyme or substrate concentration will increase the rate of reaction.

how does a phenol red-containing solution look if co2 level is low?
Answer:
The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.
Explanation:
is this correct
A phenol red-containing solution with low CO2 level will appear red.
Phenol red is a substance that serves as an indicator. It changes in colouration in response to the acidity or alkalinity of solutions.
In acidic solutions, phenol red turns yellow while the colour is red in basic solution.
Solutions with high CO2 levels are acidic while those with little to no CO2 concentrations are basic.
Thus, in a low CO2 solution, phenol red will turn red and the solution will generally appear red.

VELOCITY IS THE SPEED AND DIRECTION OF MOVEMENT
Explanation:
velocity
reason: The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

What type of bond if formed between the atoms of this type of compound
Answer:
The main component are electrons.
A chemical bond is any attractive interaction that keeps atoms short. This interaction can be directional as the bond between two atoms within a molecule, or non-directional as the electrostatic interaction that keeps the ions of an ion crystal in contact. It can be strong like the two previous examples, or weak as van der Waals interactions that are dipolar in nature.
Many models exist to describe these interactions. For example, the chemical bond between two atoms within a molecule can be described with the Lewis model or with a quantum model, like the theory of molecular orbitals. In both cases, the origin of the interaction is a sharing of electrons between the two partner atoms of the chemical bond.
There are three types of chemical bonds: single bonds, double bonds, and triple bonds. Indeed, the type of chemical bond depends on the number of electrons shared between the bound atoms:
* Simple bonds have 2 shared electrons.
* Double bonds have 4 shared electrons.
* Triple bonds have 6 shared electrons.
This number of electrons shared between the atoms depends on the electronic structure of these atoms and thus on the rules of the byte and the duet.

A scientist studying the properties of two different gases recorded this data. If the scientist wants to study gas samples A and B at
standard temperature and pressure (STP), what must she do before continuing experimentation?
Answer:
C. Decrease the pressure of Gas A and increase the temperature of Gas B.
Explanation:
The values for standard temperature and pressure (STP) are zero degrees Celsius and one atmosphere. Since the temperature of gas A is higher than zero degrees, it will have to be reduced. Since the pressure of gas B is less than one atmosphere, it will have to be increased.
