0 degrees Celsius and 1 atmosphere.
Noble gases are tough to isolate because they do not react with any thing so it is tough to isolate them
Answer:
The amount of sunlight and rainfall in different climates determines the climate temperature and humidity hence the majority of the factors of a climate
Explanation:
The climate of a place is its average weather condition, such as the temperature, snow and rainfall, wind etc. The factors that determines the climate of a region includes the amount of sunlight received, the height above sea level etc
The amount of sunlight determines the amount of heat energy received at a location and hence the temperature of the climate
The amount of rainfall will determine how wet or cold a place as well as the dissipation of the energy from the sun.
Therefore, the amount of sunlight and rainfall in different climates determine the climate temperature and humidity and other dependent climate factors.
Explanation:
We have to find the number of moles of N₂ that are present in a sample that has a volume of 40.0 L at STP.
STP means Standard Conditions of Temperature and Pressure. These conditions are 273.15 K and 1 atm. We know that 1 mol of N₂ will occupy 22.4 L. We can use that ratio to find the answer to our problem.
1 mol of N₂ = 22.4 L
moles of N₂ = 40.0 L * 1 mol/(22.4 L)
moles of N₂ = 1.79 mol
Answer: 1.79 moles of nitrogen are present.
C The total mass of the reactants equals the total mass of the products
