Answer:
2. Products; FeCl2 and H2S
Reactants; FeS and HCl
3. a) 36g of water
b) 64g of oxygen
Answer:
they use symbols to represent land features.
Explanation:
25 cm x 12 cm x 13 cm => 3900 cm³
1 cm³ = 1 mL , therefore: 3900 x 1 => 3900 mL
hope this helps!
Answer:
H₂S + Cl₂ —> S + 2HCl
Explanation:
? + Cl₂ —> S + 2HCl
To balance the equation above, we must recognise what atoms are present in the products.
The products contains S, H and Cl.
Thus, S, H and Cl must also be present in the reactants.
Considering the equation given above, we can see clearly that H and S is missing in the reactants.
H and S together as a compound is expressed as H₂S.
Now, we shall input H₂S into the equation to obtain the complete equation. This is illustrated below:
? + Cl₂ —> S + 2HCl
H₂S + Cl₂ —> S + 2HCl
Next, we shall verify to see if the equation is balanced.
There are 2 atoms of H on both sides of the equation.
There are 2 atoms of Cl on both sides of the equation.
1 atom of S exist on both sides of the equation.
Thus, the equation is balanced.
