Answer: (1) Inhales (breathes in) Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. (1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
Alkene is the group of hydrocarbon molecules that contains at least one double bond. So, A, C and D would be named ending with -ene.
Electrical to chemical energy
Explanation:
If the batteries in a flashlight are rechargeable, the energy conversion that would take place to recharge the battery is from electrical to chemical energy.
- A battery is an electrochemical cell in which chemical reactions produces electrical currents.
- This is a typical energy conversion from chemical to electrical energy.
- When such batteries are to be recharged, the revere process is followed.
- Electrical energy are used to drive chemical reactions.
- This in turn makes the battery recharged and on its own, it can further chemical reactions to produce electrical energy.
- During charging, the potential of the battery increases.

Answer:
repelled
Explanation:
like charges repel one another
Answer:
2.8M
Explanation:
The following data were obtained from the question:
Volume of stock solution (V1) = 40mL
Molarity of the stock solution (M1) = 7M
Volume of diluted solution (V2) = 100mL
Molarity of diluted solution (M2) =?
Using the dilution formula, we can easily find the molarity of the diluted solution as follow:
M1V1 = M2V2
7 x 40 = M2 x 100
Divide both side by 100
M2 = (7 x 40)/100
M2 = 2.8M
Therefore, the molarity of the diluted solution is 2.8M
