Answer:
Climate changes and earthquakes are B.effects of evolution
Explanation:
Climate change consists of variations in the state of the weather and earthquakes (earth tremors) are due to the movement of tectonic plates. Both have existed since the formation of the Earth, due to a variety of natural circumstances, of man (for example, global warming generates climate change).
Answer:
Explanation:
Carbon dioxide is a chemical compound that consists of two oxygen atoms and one carbon atom. … Carbon Dioxide (CO2) is a gas with a molecular structure composed of two oxygen atoms and one carbon atom. It is an important greenhouse gas because of its ability to absorb infrared wavelengths.
Gaseous
The atoms are taking up the volume of the entire container
Answer:
P4 + 5O2 --> 2P2O5
2C2H6 + 7O2 --> 4CO2 + 6H2O
Explanation:
<u>Answer:</u> The concentration of KOH solution is 1.215 M
<u>Explanation:</u>
For the given chemical equation:

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 KOH.
We are given:

Putting values in above equation, we get:

Hence, the concentration of KOH solution is 1.215 M
