Main Answer:
Given data:
Initial Pressure P1 = 570 mm hg
Initial Volume V1 = 2270 ml
Final Pressure P2 = ? mm hg
Final Volume V1 = 1250 ml
According to the ideal gas equation,
PV = constant.
P1V1 = P2V2
P2 = P1V1/V2
P2 = (570 x 2270) / 1250
P2 = 1035.12 mm hg
The final pressure at volume of 1250 ml is 1035.12 mm hg.
Explanation:
What is ideal gas equation ?
The ideal gas equation is as follows:
PV = nRT
where P = Pressure
V = Volume
n = number of moles of gas
R = Universal gas constant
T = Temperature
This ideal gas equation provides the macroscopic particles behavior of the gas. At this condition, the particles of the gas, won't be attract or repel each other. It is consider as the stable condition.

C. arteries, veins, capillaries
Answer:
A. Protons are positive and carry a charge of +1
B. Neutrons are neutral so carry a charge of 0
C. Electrons are negative and carry a charge of -1
Using an example like Christmas lights, I would say yes because normally a lot of them would go out if one light is broken.
In a chemical reaction, the atoms of the starting species called reactants rearrange to form new substances which are the products of the chemical reaction. The identities of the atoms involved in the reaction remain the same. Their number also stays the same before and after the reaction
