Answer:
4HCl(g) + O₂(g) → 2Cl₂(g) + 2H₂O(g)
Explanation:
In order to find the equation we should state:
The reactants → Hydrogen chloride (HCl) and oxygen (O₂)
The products → Chlorine gas (Cl₂) and water gas (H₂O)
The balanced equation is:
4HCl + O₂ → 2Cl₂ + 2H₂O
It is a redox reaction, where the oxygen reduces to make water, and the chloride is oxidized to produce elemental chlorine.
Answer:
6.2g of NaBr are produced
Explanation:
The reaction of HBr with NaOH occurs as follows:
HBr + NaOH → NaBr + H2O
<em>Where 1 mole of each reactant produce 1 mole of NaBr</em>
To solve this question we need to find the moles of each reactant using their molar mass. With moles we can find limiting reactant and the moles (And mass) of NaBr produced, as follows:
<em>Moles HBr -Molar mass: 80.9119g/mol)-</em>
4.9g * (1mol/80.9119g) = 0.0606 moles HBr
<em>Moles NaOH -Molar mass: 40g/mol-</em>
3.86g * (1mol/40g) = 0.0965 moles NaOH
As the reaction is 1:1 and the moles of HBr < Moles NaOH, the limiting reactant is HBr and moles of NaBr produced are 0.0606 moles.
The mass of NaBr (Molar mass: 102.894g/mol) is:
0.0606 moles * (102.894g/mol) =
<h3>6.2g of NaBr are produced</h3>
Answer:
Ca^+2
Explanation:
Hence, the correct option is A.
Answer:
There are produced 6.72 g
Explanation:
This is the reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
1 mol of glucose reacts with 6 moles of oxygen, to make 6 moles of dioxide and 6 moles of water
Molar mass of CO₂ = 46 g/m
Moles CO₂ = 10.3 g/ 46g/m = 0.224 moles
Ratio is 6:1
6 moles of CO₂ are made from 1 mol of glucose
0.224 moles of CO₂ are made from (0.224 . 1)/6 = 0.0373 moles of glucose
Molar mass glucose = 180.15 g/m
Mass glucose = moles . molar mass
0.0373 m . 180.15 g/m = 6.72 g
