Answer:
The answer is option a. The evaporation of water from the skin
Explanation:
An endothermic reaction is any synthetic reaction that retains heat from its environment. The ingested energy gives the enactment energy to the reaction to happen.
No new bonds formed, no bonds broken in this example. water molecules go from liquid to vapour (gas ), intermolecular bond exist between polar (-OH) molecules and energy is required to break these bonds during the change from liquid to gas. So, it is endothermic .
Remaining three above examples are exothermic. combustion of gas releases energy(exothermic). burninig of the candle exothermic because the energy released from the oxygen into carbon dioxide and water.oxidation of iron also exothermic
Yes, because if you have a flower and it reproduces then there's a HIGH chance that the next flower will be the same color because of traits! <span />
I believe the answer would be a.
The partial pressure of carbon dioxide is 75 torr.
<h3>What is Dalton's theory?</h3>
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
- Total pressure of mixture = 825 torr
- Partial pressure of Nitrogen = 600 torr
- Partial pressure of oxygen = 150 torr
- Partial pressure of carbon dioxide = ?
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.
