Answer:
Mass of barium sulfate = 8.17 g
Explanation:
Given data:
Mass of sodium sulfate = 4.98 g
Mass of barium sulfate produced = ?
Solution:
Na₂SO₄ + Ba(NO₃)₂ → BaSO₄ + 2NaNO₃
Moles of sodium sulfate:
Number of moles = mass/molar mass
Number of moles =4.98 g / 142.04 g/mol
Number of moles = 0.035 mol
Now we will compare the moles pf sodium sulfate and with barium sulfate.
Na₂SO₄ : BaSO₄
1 : 1
0.035 : 0.035
Mass of barium sulfate:
Mass = number of moles × molar mass
Mass = 0.035 mol ×233.4 g/mol
Mass = 8.17 g
Answer:
it is calcium and bromine
Explanation:
this is because they are both ionic compounds
<u>Answer:</u>
<u>For a:</u> The reaction is a type of synthesis reaction.
<u>For b:</u> The reaction is a type of double displacement reaction
<u>For c:</u> The reaction is a type of combustion reaction.
<u>Explanation:</u>
The given chemical reaction is:
The above reaction is a type of synthesis reaction because calcium and bromine are combining in their elemental state to form a calcium bromide compound.
The given chemical reaction is:
The above reaction is a type of double displacement reaction because here exchange of ions takes place.
The given chemical reaction is:
The above reaction is a type of combustion reaction because a hydrocarbon is reacting with oxygen gas to produce carbon dioxide and water molecule.
Answer:
23.20% Na, 4.26% H, 18.41% C, and 54.13% O.
