I would pick "<span>Unsaturated hydrocarbons are very reactive." This is because while unsaturated hydrocarbons are indeed more reactive than their saturated counterparts, they still do require some energy, called activation energy, to be overcome before the reactions occur.</span>
Answer:
Mass of 
produced = 32 g
Explanation:
Calculation of the moles of 
as:-
Mass = 82.4 g
Molar mass of = 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-
2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms 
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of produced = 32 g</u>
Answer:
A
Explanation:
I would assume A because it says in the problem statement that chooses aluminum because he is worried that composite will suddenly fail... therefore he would use aluminum because it would bend before breaking and therefore show warning.
Explanation:
When an electron absorbs the light it jumps from its lower energy state towards the higher energy state. This known as absorption.
When an electron come backs from higher energy to lower energy level energy is released emitted out in the form of light. This is known as emission.
1) n = 3 to n = 5 ,This transition will be absorption.
2) n = 1 to n = 3 ,This transition will be absorption
3) n = 3 to n = 2 ,This transition will be emission.
4) n = 2 to n = 1 ,This transition will be emission.
Ummmmmmm im not sure wat ur asking
