Answer:
189.5
Explanation:
its very very very very easy
Answer:
1. Exothermic reaction
2. Is being released
3. The energy comes from the change in energy between reactants and products
Explanation:
The reaction is producing energy. A reaction that produce energy is called a <em>Exothermic reaction.</em>
<em />
As the energy is produced, the energy is being <em>released.</em>
<em />
As you can see in the image, the energy of the reactants is higher than the energy of the products. This change of energy in the chemicals produce the production of energy as heat.
10. is C or gas and 11. is B liquid.
Answer:
4000 L
Explanation:
Step 1:
Data obtained from the question. This include the following:
Initial volume (V1) = 2000 L.
Initial temperature (T1) = 100 K.
Initial pressure (P1) = 100 kPa.
Final temperature (T2) = 400 K.
Final pressure (P2) = 200 kPa.
Final volume (V2) =..?
Step 2:
Determination of the new volume of the gas.
The new volume of the gas can be obtained by using the general gas equation as follow:
P1V1/T1 = P2V2/T2
100 x 2000/100 = 200 x V2/400
Cross multiply to express in linear form.
100 x 200 x V2 = 100 x 2000 x 400
Divide both side by 100 x 200
V2 = (100 x 2000 x 400)/(100 x 200)
V2 = 4000 L
Therefore, the new volume of the gas is 4000 L
