A student listed the following characteristics of a hydronium ion: 1) is attracted to negatively charged ions, 2) contains two hydrogen atoms, 3)
contains one oxygen atom, 4) is formed as a result of the dissociation of an H2O molecule. Which statement is incorrect?
A. 1
B. 2
C. 3
D. 4

the answer is c

explanation:

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
