CaO + H2O → Ca(OH)2
the number of O atom on the left side is 1 and on the right side 2 so,
we put 2H2O instead of H2O
CaO + 2H2O → Ca(OH)2
now we have to put 2Ca(OH)2 instead of Ca(OH)2 to make H atoms equal on both sides 4
CaO + 2H2O → 2Ca(OH)2
now we have to put 2CaO instead of CaO to make Ca atoms equal on both sides 2 atoms.
∴ the final balanced equation is:
2CaO + 2H2O → 2 Ca(OH)2
∴ the coefficients are 2 2 2
Yes. A mixture can be made up of just elements without the use of a compound, you can also just use compounds in a mixture without any elements
Explanation:
Thermosetting plastic are made up of long chain of molecules which are cross-linked and can be moulded into different shape and size.
Answer: Heyo Kenji Here! Here's your answer- Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.
Explanation: Hope this helps!
Have a nice day!

Answer:
Percentage of first isotope = 69.152 %
Percentage of second isotope = 30.848 %
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope:
Let % = x %
Mass = 62.9296 amu
For second isotope:
% = 100 - x % (Since, there are only two isotopes)
Mass = 64.9278 amu
Average mass = 63.546 amu
Thus,
Solving,
1.9982 x = 138.18
Thus,
<u>Percentage of first isotope = x = 69.152 %</u>
<u>Percentage of second isotope = 100 - x % = 30.848 %</u>
