When the chemical response is balanced, the mass of the reactant is equal to the mass of the reactant.
<u>Grounded on the law of Conservation of Mass</u>
We balance the chemical equation since tittles aren't destroyed in the process and the mass is conserved. The mass of the reactant is equal to the mass of the product. No new titles are created or destroyed, there was only rearrangement or regrouping of tittles. This also means the number of titles of rudiments in both the product and reactant is equal.

Answer:
Scalar Quantity
Explanation:
A scalar has only magnitude, while a vector quantity has magnitude and direction.
An example of a vector would be 5m/s West.
Answer:
∆PE = 749.7 J
At 0.9 m high, PE = 793.8 J
At 1.75 m high, PE = 1543.5 J
Given:
Circumference = 2 m
Angular speed, ω = 1 rev/s = 2π radians/s
If the radius is r, then
2πr = 2
r = 1/π m
The linear (tangential) speed is
v = rω
= (1/π m)*(2π rad/s) = 0.5 m/s
Answer: 0.5 m/s
It works by you putting leverage on one side makes more force go to the other side so if you put a crowbar in between a door and you push on one side the other will push the opposite side with more force<span />
