Answer:
I'd probably say both. It physically changes because it creates CO2. It chemically changes because they are basically working together for the atoms to rearrange and creates a chemical reaction.

Answer:
animals and other living things
Explanation:
All living organisms have been classified and grouped into a hierarchical system of classification. Kingdom is the highest level in this system comprising of 6 other levels. However, there are different kingdoms that harbors different organisms. The kingdoms are: animalia, plantae, protista, monera, fungi etc.
However, among other kingdom of organisms, organisms in the Kingdom Animalia are the only ones that possesses muscle tissues etc. This shows a contrast between animals and other living things.
Answer:
The resulting pressure is 2.81 atm
Explanation:
According to Dalton's Law of Partial Pressure, each of the gases (A and B) will exert their pressure independently. If we use Boyle's Law to calculate the pressure of each of the gases separately we have:
Pressure of gas A:
p1V1 = p2V2
p1 = 2.4 atm
V1 = 722 mL
V2 = 722 + 169 = 891 mL
p2 =?
Clearing p2:
p2 = (p1V1)/V2 = (2.4*722)/891 = 1.94 atm
Pressure of gas B:
p1 = 4.6 atm
V1 = 169 mL
V2 = 169+722 = 891 mL
p2=?
Clearing p:
p2 = (4.6*169)/891 = 0.87 atm
Dalton's expression for total partial pressures is equal to:
ptotal = pA + pB = 1.94+0.87 = 2.81 atm
Answer:
P1 =4 atm
T1= 20°C
P2=1 atm
T2=?
According to Gay-Lussac's Law or Third Gas Law,
P1T2=P2T1
4×T2=1×20
T2= 20/4
T2= 5°C
Answer At 5°C temperature does a gas at 1.00 atm !
