Answer : The concentration of the NaOH solution is, 0.738 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 the NaOH solution is, 0.738 M
The data gotten from ice cores could scientists tell the about future climate change.
Answer:
Actual velocity of the ping-pong ball= 5 m/s
Explanation:
velocity of ping pong ball because of the shot gun= 4 m/s North
velocity added to the ping-pong ball due to the wind=3 m/s
These velocities are perpendicular to each other. so we use Pythagoras theorem to find the resultant velocity of the ping- pong ball
so the actual velocity of the ping-pong ball =V= √4²+3²
V= √25
V= 5 m/s

The combustion of the fatty acid called stearic acid has the the complete equation; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
<h3>What is combustion?</h3>
The term combustion has to do with the burning of a substance in air. For organic compounds, we get carbon dioxide and water as the products.
Thus, for the combustion of the fatty acid called stearic acid, the complete equation is; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
