Carbon Dioxide is formed when two oxygen atoms chemically combine with a carbon atom. The term that will best describe carbon dioxide is a compound. That will make the correct answer D.
<u>Answer:</u> The amount of water required to prepare given amount of salt is 398.4 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 0.16 M
Given mass of manganese (II) nitrate tetrahydrate = 16 g
Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol
Putting values in above equation, we get:
Volume of water = Volume of solution = 398.4 mL
Hence, the amount of water required to prepare given amount of salt is 398.4 mL
a specific hypothesis to test with a controlled experiment
Answer:
c. the heart
all the rest actually will excrete, the heart is in a closed system so contributes to excretory organs but doesn't actually do it barring an accident
