Answer:
Acceleration is :
a = 2.89 m/s2
Explanation:
Acceleration : It is the change in the velocity of the object per unit time.
The object starts from the rest , so the initial velocity of the object is zero.
Initial velocity , u = 0
Final velocity = 100 km/h
Change the velocity to m/s because[ time unit is in second(9.60 s)]
1 km = 1000 m
1 hour = 60 x 60 sec = 3600 sec




v = 27.78 m/s
u = 0 m/s
time = 9.60 s
The acceleration"a" is calculated using :




An alpha particle is identical to a helium atom that has been stripped of its two electrons
Answer: 1.98 g
Explanation:
To calculate the moles :
The balanced given equation is:
According to stoichiometry :
4 moles of
will produce = 2 moles of
Thus 0.22 moles of
will produce=
of
Mass of
Thus 1.98 g of water is produced along with 5.0 L of
at STP
Answer:
See explanation
Explanation:
A limiting reactant is the reactant in a reaction that is done reacting first, because there are less moles of it than are needed for a full reaction with the other compound or compounds.
