Explanation:
I think the answer is this for a better check mass- mass ratio in stoichiometry lesson
Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
Answer:
This question is so confusing, I'm sorry
<span>Xenon has 8 valence electrons, each hydrogen atom has 1, therefore you have 8+4=12 valence electrons. 8 electrons are used to make 4 bonds between the Xe atom and the 4 hydrogen atoms. That leaves 12-8=4 left over electrons, which will occur in two lone pairs of electrons on the center xenon atom. There are 4 bonding pairs and two lone pairs of electrons and they will be arranged in an octahedral arrangement around the center atom, with the lone pairs across the molecule (180 degrees from each other). The resulting molecular structure will be square planar.</span><span>

61g/mol
Explanation:
The empirical formula of compound is its simplest formula. It shows the simplest ratio by which the atoms are combined.
In the formula C₄H₁₀O₄
we have:
4 moles of carbon 10 moles of hydrogen 4 moles of Oxygen;
4 : 10 : 4
The simplest ratio can be obtained by dividing through by the highest common factor which is 2;
4/2 10/2 4/2
2 5 2
the empirical formula is C₂H₅O₂
The formula mass is the sum of the atomic weights;
C₂H₅O₂ = (2 x 12) + (5x1) + (2x 16) = 24 + 5 + 32 = 61g/mol
