Answer:
6 moles
Explanation:
Take a look at the balanced chemical equation for this synthesis reaction

Notice that you have a
1
:
3
mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.
So, if you have
2
moles of nitrogen taking part in the reaction, you will need

<span>The ball will be subject to potential and kinetic energy at this point in time as it is still rising away from the ground and not yet subject to the pull of gravitational force. The potential energy will account for the forces occurring due to change in relative position of the ball during its flight while kinetic energy will account for the energy derived by its motion.</span>
Answer:
coordination number
Explanation:
Coordination number -
In a crystal lattice , the number of atoms that are surrounded to a particular atom , is referred to as the coordination number of the crystal.
In the field of crystallography and chemistry , it is also called the ligancy.
In coordination chemistry , the number of ligands attached to the central metal atom is also known as the coordination number of the coordination compound.
Hence, from the given statement of the question,
The correct term is coordination number.
Answer:
Initial temperature, T1 = 15°C
Explanation:
Given the following data;
Initial volume, V1 = 250 mL to Liters = 250/1000 = 0.25 L
Final temperature, T2 = 30°C
Final volume, V2 = 0.5 L
To find the initial temperature T1, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
Making T1 the subject of formula, we have;
Substituting into the formula, we have;
<em>Initial temperature, T1 = 15°C</em>
Answer:
B.) and D.)
Explanation:
A.) is incorrect because the reaction technically never stops if the system remains in tact. Rather, there is just an equal amount of forward and reverse reactions occurring. This means that the overall concentrations of the reactants and products stays the same.
B.) is correct because when the concentrations of the reactants and products remain unchanged, then equilibrium is reached.
C.) in incorrect because, at this point, the concentrations of the reactants are still decreasing and the products are still increasing. If point 2 is specifically referencing the intersection of the lines, this cross symbolizes equal concentrations of the reactants and product. Keep in mind that equal concentrations does not equal equilibrium.
D.) is correct because a reaction moving forward means that mostly product is being created. In other words, the concentration of the product should be increasing. Meanwhile, the concentration of the reactants decrease because they are being used to create the product. As seen in the graph, the product (H₂O₂) is rapidly increasing in concentration. Meanwhile, the concentrations of the reactants (O₂ and H₂O) are decreasing as they would in a forward reaction.
