Answer:
the nucleus is called the mass number and, expressed in amu, is approximately equal to the mass of the atom
Explanation:
N₂ : limiting reactant
H₂ : excess reactant
<h3>Further e
xplanation</h3>
Given
mass of N₂ = 100 g
mass of H₂ = 100 g
Required
Limiting reactant
Excess reactant
Solution
Reaction
<em>N₂+3H₂⇒2NH₃</em>
mol N₂(MW=28 g/mol) :
mol H₂(MW= 2 g/mol) :
A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactans become a limiting reactants
From the equation, mol ratio N₂ : H₂ = 1 : 3, so :
N₂ becomes a limiting reactant (smaller ratio) and H₂ is the excess reactant
U can assume that riding the bus is a faster way to get to school because it is capable of a faster speed than a bicycle
Answer:
D. severe weather events would occur more often
Explanation:
If the average global temperatures on Earth increased, there are high chances of severe weather events occurring more often
- Weather events are devastating in nature.
- Examples are hail, blizzards, Lightning and thunderstorm
Increase in average global temperatures can result in these disasters.
When global temperatures increases, polar ice will melt and sea levels will increase.
This will cause storms in coastal areas and flooding.
