Answer:
The reaction will proceed to the left to attain equilibrium.
Explanation:
The question is missing but I guess it must be about <em>how the reaction will proceed to attain equilibrium.</em>
First, we have to calculate the partial pressures using the ideal gas equation.
Now, we have to calculate the reaction quotient (Qp).
Since Qp > Kp, the reaction will proceed to the left to attain equilibrium.
<h3><u>Answer;</u></h3>
<em>-49 °C</em>
<h3><u>Explanation and solution;</u></h3>
- Considering the fact that, the specific heat capacity of aluminum is 0.903 J/g x C, and the heat of vaporization of water at 25 C is 44.0 KJ/mol.
Moles water = 0.48 g / 18.02 g/mol
=0.0266 moles
<em>Heat lost by water</em> = 0.0266 mol x 44.0 kJ/mol
=1.17 kJ => 1170 J
<em>But heat lost =heat gained</em>
<em>Therefore;</em> Heat gained by aluminium = 1170 J
1170 = 55 x 0.903 ( T - 25) = 49.7 T - 1242
1170 + 1242 = 49.7 T
T = 48.5 °C ( 49 °C <em>at two significant figures)</em>
<em>Hence</em>, final temperature = 49 °C
Answer:
Enzyme Active Site and Substrate Specificity
There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule.
He answer in here is b.7.5 cubic meters. We know this when we do the following calculation:
<span>(10 m^3) x (1 / 1.5) x ((32 + 273) / (273)) = 7.5 m^3
</span>

Explanation:
Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.
Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.
Differences:
Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.
• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.
• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.
• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.
