Answer:
1. Molality.
2. Concentration.
3. Percent by mass.
4. Mole fraction.
Explanation:
Molarity is the measurement by which the number of moles is measured by a solute. The solution here is one liter respectively.
Concentration is the product which is emerged when the amount of the solute is divided by the amount o the solvent or solution.
Mole fraction refers to the number of component moles divided by the number of the solution moles.
Boyle's law gives the relationship between pressure of a gas and volume.
It states that at a constant temperature the pressure of gas is inversely proportional to volume of gas.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are given on the left side and parameters for the second instance are given on the right side of the equation.
substituting these values in the equation
6.21 atm x 3.17 L = 5.57 atm x V
V = 3.53 L
new volume is 3.53 L
<span>At room temperature and atmospheric pressure, nothing happens when the two gasses are mixed. However, at high temperature and pressure (450C, 200atm), in the presence of an iron oxide catalyst, the production of ammonia is thermodynamically advantageous.</span>
Answer:
Is this math? Cause as a fourth grader, I can do Algebra, but not this.
Explanation:
Answer: 
Explanation:
Heat of reaction or enthalpy change is the energy released or absorbed during the course of the reaction.
It is calculated by subtracting the enthalpy of reactants from the enthalpy of products.
= enthalpy change = ?
= enthalpy of products
= enthalpy of reactants
For the given reaction :
