The mechanics of a power plant that generally uses nuclear energy in order to generate electricity lies in the principle of nuclear fission between radioactive atoms. In addition, among its major arguments on why it is still a matter of ethical issue is because of the intensive maintenance it requires for the disposal of its radioactive wastes.
From the given chemical equation we see that 43 kcal of
energy is needed for every 2 moles of NO. First let us calculate the moles of
NO with a molar mass of 30 g/mol.
moles NO = 112 g / (30 g/mol) = 3.73 mol
So the total heat absorbed is:
heat = (43 kcal / 2 mol) * 3.73 mol
<span>heat = 80.195 kcal</span>
Answer:
The answer is b. Carbon Tetrachloride
Explanation:
Let's discard the other options:
a. It couldn't be carbon chloride because there are four (4) chloride ions in the molecular formula. The molecular formula for the carbon chloride must be CCI. So, this answer is wrong
c. It could be monocarbon tetrachloride because there are 4 chloride ions and 1 carbon ion, but it's not necessary to use the prefix "mono" because there is just one carbon ion in the formula. In that way, when we mention carbon in the name, there is implicit that there is just one carbon atom in the formula. So, this answer could be ok, but isn't the best.
d. It couldn't be calcium chloride because there isn't any calcium ion or atom in the formula. The molecular formula for the calcium chloride must be CaCI. So, this answer is wrong
Answer:
Number of moles = mass/molar mass
Explanation:
Given data:
mass of Al = 11 g
Moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of aluminium is 27 g/mol
Now we will put the values in formula.
Number of moles = 11 g/ 27 g/mol
Number of moles = 0.41
The number of moles in 11 g Al are 0.41 mol.
it is located at the origin so A
hope this helped ^_^
