Explanation:
1) Boyle's Law: This law states that pressure is inversely related to the volume occupied by the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
- When the size of the chamber is increased the volume occupied the gas will increase with which pressure exerted by the gas will decrease down.
- When we press the inflated balloon the pressure on the gas is increased with which volume of the occupied by the gas inside the balloon decreased.
2) Charles' Law: This law states that volume occupied by the gas is directly related to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
- The size of the balloon deceases because the in winters the temperature decreases with which volume of the gas present in the balloon also decreases.
- When the flexible closed container is heated the temperature of the gas inside the container increases with which the volume occupied by the gas in the container will increase resulting in expanding of container.
3) Avogadro's Law: This law states that volume occupied by the gas is directly related to the number of moles of the gas at constant pressure and temperature.
(At constant temperature and pressure)
When we blow air into the balloon the umber of air particles increases with which the volume of the gas inside the balloon also increases resulting in increase in size of the balloon.
Answer:
The heat of reaction -1.9 kilo Joules.
Explanation:
Volume of the hydrogen peroxide solution = 50.0 mL
Volume of the ferric nitrate solution = 10.0 mL
Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL
Heat capacity of the mixture = c = 4.18 J/g°C
Change in temperature of the mixture = ΔT = 7.47°C
Heat absorbed by the mixture = Q
Heat release due to reaction = -Q'
-Q' =Q (law of conservation of enrage)
Q'= -Q = -1.9 kJ
The heat of reaction -1.9 kilo Joules.
Answer:
i believe it's c but I'm not one hundred percent sure
Explanation:
Answer:Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.
Explanation:
B this is because the forms of matter are solid liquid and gas. L m k if this is correct
