Endothermic reactions<span>. An </span>endothermic reaction occurs <span>when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the </span>reaction<span> takes in energy, therefore there is a temperature decrease in the surroundings.</span>
Answer:
C
Explanation:
1atm=760torr
X=250torr
Cross multiply
760torrX=250torr*atm
Divide both sides by 760torr
X=250torr*atm/760torr
X=0.32895atm
X=0.329atm
Option C is collect
Hemoglobin with bound carbon dioxide and hydrogen ions is carried in the blood back to the lungs, where it releases the hydrogen ions and carbon dioxide and rebinds oxygen. Thus, hemoglobin helps to transport hydrogen ions and carbon dioxide in addition to transporting oxygen.
