Answer:
Explanation:
we know that number of moles=mass(in grams)/molar mass
for the mass of oxygen the equation becomes
mass=number of moles*molar mass
They can be differnt shape or one must weight more then the other one
The speed of light is (2.998x108/3.00x109) meters per second = 300,000 kilometers per second.
Answer:
Decomposition
Explanation:
The equation 2 H₂O₂ → 2 H₂O + O₂ is an example of a decomposition reaction. During decomposition, a compound breaks down into two or more products under the favorable conditions, without combining with other reagents.
However, the reaction can be catalyzed using a suitable catalyst.
Answer:
0.5m/s²
Explanation:
Given parameters:
Mass to be pushed = 300kg
Force = 150N
Unknown:
Acceleration = ?
Solution:
To solve this problem, we need to apply newtons second law of motion which is expressed below:
F = m a
F is the force
m is the mass
a is the acceleration
150 = 300 x a
a = 0.5m/s²
