Answer:
0.59 mol Na2CO3
Explanation:
M(Na2CO3) = 2*23.0 + 12.0 + 3*16.0 = 106 g/mol
63 g Na2CO3 * 1 mol Na2CO3/106 g Na2CO3 = 0.59 mol Na2CO3
Answer:
Explanation:
Hello,
By applying the Dalton's law, we can compute the partial pressure of the helium has:
Now, solving for the partial pressure of the helium gas we get:
On the other hand, the mass of the helium gas is computed via the ideal gas equation in terms of the helium's mass:
Best regards.
Magnesium is in the second group in the periodic table, which means that its outer shell is an s-orbital which contains 2 valence electrons.
Hydrogen also has an s-orbital as an outer shell but it only contains 1 valence electron. The electron dot diagram would look like this:
H· ·Mg· ·H
Each hydrogen shares one electron with magnesium and the magnesium shares one of its electrons with each hydrogen resulting in two covalent bonds.
H:Mg:H and this gives us the compounds MgH₂
<span> The nuclear reactor powers plants to inhale heats that are needed to create/produce steam- (a gas that comes from liquid at its boiling point) The process is called fission. Fission entails the splitting on atoms in the nuclear reactor.

Here is your answer
Ru(MnO4)2
We know that
valency of Ru=2
Valency of permanganate(MnO4)= 1
So, on combining the two
Ru(MnO4)2 is obtained by transferring of electrons.
