What mass of sulfur must burn to produce 3.42 L of So2 at STP

1 answer:

7 0

Number of moles SO2 :

1 mol SO2 -------- 22.4 L ( at STP )
? mol SO2 --------- 3.42 L

1 x 3.42 / 22.4 => 0.152 moles of SO2

Therefore:

Molar mass SO2 => 64.066 g/mol

1 mole SO2 ---------- 64.066 g
0.152 moles SO2 ---- ( Mass of SO2)

Mass of SO2 = 0.152 x 64.066 / 1

Mass of SO2 = 9.738 g

So, you need to have same ammount of atoms on the left and on the right side of the equation. You need to count the ammount of attoms of every substance on the left, and make sure that on the right side the ammount is same. For example in the 1st one it’s 6Sn+2P4=2Sn3P4, so that you have 6atoms of Sn on the left and 6 atoms of Sn on the right, same with the P

18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the

MAXImum [283]

Answer: The chemical reaction for the synthesis reaction is given below.

Explanation:

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:

$A+B\rightarrow AB$

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

$2Ca(s)+O_2(g)\rightarrow 2CaO(s)$

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.
