Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus, the concentration of NaOH is, 0.336 M
Answer:
<h3>The answer is 280 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 70 kg
acceleration = 4 m/s²
We have
force = 70 × 4
We have the final answer as
<h3>280 N</h3>
Hope this helps you
The answer to this question is approximately equal to 57.8
It’s A and D have a good day!!
Answer:
No.
Explanation:
When mass is destroyed, it has to have been transformed into something else. Otherwise that would violate the Law of Conversion of Mass. In this case, the wood converted some of its mass in chemical energy to thermal (or heat) energy.
