Answer: A. 11
Explanation: The balance equation is:
C7H16 + 11 O2 => 7CO2 + 8H2O
This is a combustion reaction where a hydrocarbon reacts with oxygen gas to form CO2 and H2O.
Answer:
- 1.22KJ
Explanation:
First we put down the equation of the reaction;
NH4Cl(s)<-------->NH3(g) + HCl(g)
The equilibrium constant K is obtained from;
K= P(NH3) × P(HCl)
Where;
P(NH3)= pressure of ammonia
P(HCl)= pressure of hydrogen chloride gas
Pure solids and liquids are not included in the equilibrium constant expression. This is because they do not affect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1. Remember that the activity, a, of any solid or liquid in a reaction is equal to 1. Hence [NH4Cl]= 1
K= 1.03 × 1.18 = 1.22
∆G° = -RTlnK
R= 8.314 JK-1mol-1
T= 465°C +273= 738K
K= 1.22
lnK= ln(1.22)= 0.19885
∆G= -(8.314 ×738 ×0.19885)
∆G= -1220.1 J
∆G= -1.22×10^3 J
∆G= - 1.22KJ
Answer:
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. Hope this helps, mark as brainliest please!
