Using the formula 2n² put in the value of n which is 4
the answer is 2×4² which is 2×16
The answer is 32.
this is the maximum no of electron acceptable into the electron shell.
Please mark me as brainliest.
Answer:
The answer is True
Explanation:
This is because they are equivalent and have same number of bit.
I'm not sure if what this question is asking but ill be assuming that the average molecular mass is required. An assuming that the abundance of each isotope is 50% the average molecular mass is 69.82 amu.
Answer:
15.6 times longer is 15.625 times
Explanation:
the first one is 2.5 bigger, and then if you use that length on the area you can just cube 2.5
The largest number of molecules is the same as the largest number of moles of this molecules
to calculate the number of moles you have to divide the mass by the molar mass
molar masses:
CO2: 44,01 g/mol
CH4: 16,04 g/mol
CBr4: 331,63 g/mol
CHBr3: 252,73 g/mol
largest nº of mol= 100/(the smallest molar mass possible)
= 100/16,04
=6,23 moles
all other molecules would be smaller than 6,23 moles because the molar mass is so high.
The answer is B : 1<span>00 g of ch4</span>
