Explanation:
2CO (g) + O2 (g) → 2CO2 (g) ∆H = –566.0 kJ exothermic
2SO2(g) + O2(g) <=> 2SO3(g). Delta H = -198.2 kJ/mol. exothermic
Answer:
Hey mate.....
Explanation:
This is ur answer......
<em>While sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water.</em>

Answer:
9
Explanation:
let f(x)= x-7 be equation i
let g(x)= x^2 be equation ii
Substitute x-7 as x in equation 2
implies gf(x) = (x-7)^2=(x-7)(x-7)
substitute x=4 implies
gf(x) = (4-7)(4-7)=(-3)(-3)=9
Explanation:
Air bags help lessen injuries in an automobile crash is application of Boyle's law:
Boyle's law states that at constant temperature, the volume of given mass of a gas is directly proportional to the pressure changes.
According to this law, the volume of the air bag will increase. The bag will become bigger as a result of decrease in the gas pressure in the bag.
The bag was packed with gases under high pressure and their volume decreases appreciably. After a collision, pressure reduces and the gas expands.
helium balloon decreases in size when you put it into a freezer
A can of spray paint will explode if tossed into a fire
Both are application of Charles's law:
According to this law "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
The helium balloon decreases in size because the temperature is lowered. The particles will keep tending towards a state of rest.
A can spray paint explodes because the gas in it will keep expanding as the temperature increases in a fire.
