Question

Hi tutors, can I have a request to answer this all without me separating those questions, coz I'm saving my post question/ask an expert for my other questions. hope u understand thank you.

Show your solution to the correct number of significant figures. Use your own
periodic table to solve for molar mass.
1. Potassium nitrate when exposed to heat decomposes to potassium oxide
and gaseous nitrogen and oxygen:
4KNO,(s) → 2K,0(s) + 2N,(g) + 50,(g)
To produce 28.3 g of oxygen, how many (a) moles of KNO, and (b) grams
of KNO, must be heated?
2. Striking a match stick on the matchbox involves the reaction of potassium
chlorate and red phosphorus with the following equation:
10 KCIO, (s) + 3P, (s)→3P,0,, (s) + 10 KCI (s).
How much of each reactant will be needed to produce 105.8 g of
tetraphosphorus decaoxide (P,0,0)?
3. What mass (in grams) of fluorine gas is needed to react completely with
17.8 g of elemental sulfur, S, to form sulfur hexafluoride SF?
S, (g) + 24F, (g)→8 SF, (g)
