Answer:
A) boiling point higher than expected vapor pressure lower than expected.
Explanation:
When water is introduced with heat it vaporize at a temperature of 100 degree centigrade. When hydrochloric acid is added to the water its boiling point of water increases slightly. The difference in the boiling point is due to the presence of heavier molecules in acid.
A is the answer for this question
Answer:
a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.
Explanation:
Hello,
In this case, combustion at the automobiles' motors is not complete since gasoline usually has a considerable nitrogen oxides content (NOx) which is highly toxic when giving off from the cars. For that reason, recent advancements have shown platinum-rhodium-based catalytic converters have the capacity to catalyze the conversion of nitrogen oxides to elemental nitrogen and oxygen which are nontoxic. For that reason, answer is a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.
Regards.
Answer:
En CNPT un mol de cualquier gas ocupa 22,4 litros
Entonces hay que multiplicar
2.5 x 22.4 litros y eso es igual a 56 litros de gas metano
PD: CO2 es dióxido de carbono, metano es CH4
Answer:
The energy required is 8660.96 J.
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). This heat is given by the expression:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
- C= 4.18
- m= 74 g
- ΔT= Tfinal - Tinitial= 47 C - 19 C= 28 C
Replacing:
Q= 4.18 *74 g* 28 C
Solving:
Q= 8660.96 J
<u><em>The energy required is 8660.96 J.</em></u>
