Answer:
John Dalton, an English chemist, meteorologist, and physicists, was best known for his development of the modern atomic theory
Explanation:
Answer:
3.0002 moles
Explanation:
Data Given:
mass of NO₂ = 138.01 g
No. of moles NO₂ = ?
Solution
To find mass of sample mole formula will be used
mole formula
no. of mole = mass in grams / molar mass
Molar mass of NO₂ = 14 + 2(16)
Molar mass of NO₂ = 14 + 32 = 46 g/mol
Put values in above equation
no. of mole = 138.01 g / 46 g/mol
no. of mole = 3.0002 moles
no. of mole of NO₂ = 3.0002 moles
Answer:
A balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This means that total mass on the reactant side is equal to the total mass on the product side.
A warm front is also defined as the transition zone where a warmer air mass is replacing a cooler air mass
Dew point: The point at which air saturated with water vapor produces condensation which forms dew.
