Answer: 17.6×10^-3g of CO2
Explanation:
We first look at the stoichiometry of the balanced reaction equation. One mole of methane produces one mole of carbon dioxide. Hence 16g of methane yields 44g of carbon dioxide. If we now composed this with the given 6.40×10^-3g of methane as shown in the solution attached, we obtain the answer stated above.
We know that there are 760 mmHg per 1 atm. So in order to make this conversion, we need to set up the multiplication to cancel out the atm and leave mmHg on top. Let's set that up now and solve:
So by using this conversion factor, we are able to determine that
0.600 atm = 456 mmHg.
Answer:
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³
Explanation:
Anion:
Anion are formed when an atom gain the electrons.
Representation:
The anion of an atom is showed by adding the number of electrons gained by atom with negative sign as superscript on the symbol of an atom.
Cation:
Cation is formed when an atom lose the electron.
Representation:
The cation of an atom is showed by adding the number of electrons lose by an atom with positive sign as superscript on the symbol of an atom.
A sulfur ion with a charge of -2 = S⁻²
An iron ion with a charge of +3 = Fe⁺³
A chlorine ion with a charge of -3 = Cl⁻³

hmmmmmmmmmmmmmmmmmmm
Explanation:
not sure tbh, ask ur teacher unless someone else helps you!
Answer:
D 86.8%
Explanation:
Two bromines mole wt = 2 * 79.9 = 159.8 gm (from periodic table)
Mg = 24.3 gm
159.8 / ( 159.8 + 24.3) = .868 = 86.8 %
