The answer is 20N as when the object is accelerating at 3 m/s2 it as a force of 10N applied to it so to get to 6m/s2 3(x2) = 6 so 10(x2) = 20
The balanced equation for the reaction between Ba(OH)₂ and HCl is as follows;
Ba(OH)₂ + 2HCl ---> BaCl₂ + 2H₂O
stoichiometry of Ba(OH)₂ to HCl is 1:2
the number of HCl moles that have reacted - 0.2452 mol/L x (20.00 x 10⁻³ L)
number of HCl moles reacted = 0.004904 mol
2 mol of HCl reacts with 1 mol of Ba(OH)₂
therefore 0.004904 mol of HCl reacts with - 1/2 x 0.004904 mol of Ba(OH)₂
number of Ba(OH)₂ moles in 18.15 mL - 0.002452 mol
Therefore number of Ba(OH)₂ moles in 1000 mL- 0.002452 mol /(18.15 x 10⁻³ L)
molarity of Ba(OH)₂ is = 0.1351 M
Answer:
The mass of zinc sulfide produced is 
Explanation:
From the question we are told that
The mass of zinc is 
The mass of sulfur is 
The molar mass of
is a constant with value 65.39 g /mol
The molar mass of
is a constant with value 32.01 g/mol
The molar mass of
is a constant with value 97.46 g/mol
The reaction is

So from the reaction
1 mole of
react with 1 mole of
to produce 1 mole of 
This implies that
65.39 g /mol of
react with 32.01 g/mol of
to produce 97.46 g/mol of 
From the values given we can deduce that the limiting reactant is sulfur cause of the smaller mass
So
0.250 g of
react with 0.250 of
to produce
of 
So


Thus the mass of the mass of zinc sulfide produced is
