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.
N2 + 3 H2 >> 2 NH3
moles NH3 = 11.50 g /17.0307 g/mol=0.6753
the ratio between H2 and NH3 is 3 : 2
moles H2 needed = 0.6753 x 3/2 =1.013
mass H2 = 1.013 mol x 2.106 g/mol=2.042 g
Answer:
50
Explanation:
so you'll have to apply Newton's 2nd law which is F=ma and then substitute the values that you already have in the question as in, the force is 200 and you'll have to find the acceleration by working it out which is 4m/s² and then find the mass by dividing 200 by 4 so the actual mass is 50kg ✌️❤️
