Ok so this all boils down to Newton's second law
Force = mass X acceleration
so the force = 10 X 3 = 30N
Answer:
B. Cu (s) +Ni(NO3)2 (aq) - 2CuNO3 +Ni (s)
Explanation:
the above reaction is a substitution reaction
Steel is an alloy and consists of more than one element (mainly iron and carbon), therefore steel is a mixture.
Answer:
Oxidation number:
3*1+ oxidation number of J+2*-2= -1
Oxidation number of J = 0
Moles= mass\ relative formula mass(Ar)
moles of zinc= 7.9/30= 0.263
so we have 0.263 moles of zinc, and you need twice the amount of chlorine so therefore 0.526moles of chlorine= 0.526x 17=8.942g of chlorine
i cba to work the rest out but the most reasonable answer is 0.24 mol however if you need to use working outs, use the formula i provided earlier
