During nuclear fission, great amounts of energy are produced from____.
Answer: Out of all the options presented above, the one that completes the statement and makes it true, is answer choice D) very small amounts of mass. Nuclear fission power does not produce carbon and also produces 12% of the world's power.
I hope it helps, Regards.
Answer: The correct answer is C) carbon dioxide; calcium.
Explanation:
Carbonated soft drinks contain big concentrations of carbon dioxide, which is the bubbles that we see and feel. When these drinks are included regurly in the diet, the carbon dioxide levels are increased; and according to several studies high carbon dioxide values are related with bone loss.
Additionally, calcium is known for being an important nutrient for both formation and maintenance of bones, so inadequate intake of calcium in the diet results in a bone loss.
Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.
<h3>What is meant by a mass fraction?</h3>
Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.
The formula for a mass fraction (w) is given as,
Mass fraction (w) = mass ÷ total mass
Given,
Mass of chlorine = 35.453 grams per mole
The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole
Substituting and solving the values above as
w = mass of chlorine ÷ total mass of calcium chlorate
w = 35.453 ÷ 206.98
w = 0.171
Therefore, the mass fraction of Cl in calcium chlorate is 0.171.
