Answer:
Explanation:
In the equivalent mass measurement , one gram equivalent of metal produces 11200 mL of hydrogen gas .
11200 mL hydrogen gas is produced by 1 gram equivalent of gas at STP
11200 mL hydrogen gas is produced by 20 g of gas at STP
80 mL hydrogen gas is produced by 20 x 80 / 11200 g of gas at STP
= 142.85 mg .
= 140 mg . ( rounded to 2 sig figures )

Answer: Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of 
and a pressure of 15200 kPa
Explanation:
According to ideal gas equation:
P = pressure of gas = 15200 kPa =150 atm (1kPa=0.0098atm)
V = Volume of gas = 47 L
n = number of moles = ?
R = gas constant =
T =temperature =
Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of and a pressure of 15200 kPa
Answer:
Yes it is a scientific model because it is an outlook of a winter outlook and winter is a season and a type of weather and weather is meteorology and meteorology is a type of science so yes it is a scientific model.
Explanation:
Answer:
When light passes from one transparent medium to another, the rays are bent toward the surface normal if the speed of light is smaller in the second medium than in the first. The rays are bent away from this normal if the speed of light in the second medium is greater than in the first.
