The car's velocity after 5s : 10 m/s
<h3>Further explanation</h3>
Given
velocity=v=72 km/h=20 m/s
time=t = 5 s
acceleration=a = -2 m/s²
Required
velocity after 5s
Solution
Straight motion changes with constant acceleration
vf=final velocity
vi = initial velocity
Input the value :
The car is decelerating (acceleration is negative) so that its speed decreases
The balanced chemical reaction is:
<span>2SO2 + O2=2SO3
</span>
We are given the amounts of the reactants to be consumed in the reaction. These amounts are the starting point for the calculations.
5.0 L SO2 ( 1 mol / 22.4 L ) = 0.2232 mol SO2
3.0 L O2 <span> ( 1 mol / 22.4 L ) = 0.1339 mol O2
From the chemical reaction, the mole ratio of the reactants 2:1. Therefore, the limiting reactant is SO2.
</span><span>0.2232 mol SO2 ( 1 mol SO3 / 2 mol SO2) ( 22.4 L / 1 mol ) = 2.4998 L SO3</span>
Answer:
Sodium chloride will conduct electricity only when it is in a liquid state or in solution, this is because the ions are free to move in this state, allowing them to carry charge and conduct electricity

hope this helped you learned this in 5th grade
Can u try putting this in english please
