Answer:
The answer is True
Explanation:
I got it right on my quiz, hope this helps!
Food is made up of organic (carbon-containing) molecules that contain chemical bonds between their atoms that act as energy storage units. In addition to using the energy in food to fuel life processes, organisms construct larger organic molecules, such as proteins, DNA, and fats (lipids), using the atoms from food molecules.
What is glucose ?
The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.

Answer:
An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge.

Answer:
We should fill the acetylene tank to a pressure of 100 atm
Explanation:
Step 1: Data given
Volume tank 1 = 7.00 L
Tank 1 is filled with oxygen and has a pressure of 125 atm
Volume tank 2 = 3.50 L
Step 2: The balanced equation
2 C2H2 + 5 O2 → 4 CO2 + 2 H2O
Step 3: Calculate the pressure of acetylene
p(oxygen) * V(Oxygen) = n(Oxygen) * R * T
p(Acetylene) * V(Acetylene) = n(Acetylene) * R * T
We can assume both tanks are at the same temperature, so we can write this as followed:
p(Oxygen)* V(Oxygen) / p(Acetylene)*V(Acetylene) = n(Oxygen) / n(Acetylene)
⇒with n(Oxygen) / n(Acetylene) = 5/2
⇒with p(Oxygen) = 125atm
⇒V(Oxygen) =7L
⇒V(Acetylene) = 3.5L
⇒ this gives us: (125 * 7) / (P(Acetylene) * 3.5) = 5/2
p(Acetylene) = 100 atm
We should fill the acetylene tank to a pressure of 100 atm
