m/sec is the unit of velocity.
Explanation:
The displacement is a vector quantity. It is a measure difference between the end and start point of a moving object.
The displacement of an object is measured in metres, kilometers, centimeter or inches. But the SI unit of displacement is always converted to metres.
The time may be in minutes, hours or second, but the SI unit of time is sec
velocity with respect to displacement is defined as rate at which displacement changes with time.
from the formula :
velocity=diplscement/time
= m/sec
So the SI unit of velocity is m sec
Cu ions reduced to cu and Al oxidized to Al ions is the answer. copper ions is right hand side of the E.M.F cell where reduction take place and is reduced to copper metal. Al metal is at left hand side of the E.m.f cell where oxidation take place and is oxidized to Al ions
The answer is A because if you place the first two numbers 1 and 3
Au=2
S=3
H=6
It has to equal to the product so then you put in the last two numbers 2 and 3
Au=2
S=3
H=6
Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.
