The gas can be decomposed to yield 2.09 parts by mass of uranium for every 1 part by mass of fluorine.If the relative mass of a uranium atom is 238 and the relative mass of a fluorine atom is 19, <span> the number of fluorine atoms that are combined with one uranium atom. is 6</span>
Ok percent error is abs(calculated-actual)/actual(100%)
So 1.5/96 *100%
Answer:
Using solar energy, hydroelectric energy and wind are major ways of conserving natural resources. Trees and other organic energy sources are traditional sources of renewable energy. Forests can be replanted and hemp and other organic materials such as ethanol can be used to preserve natural resources.
Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
<u>Answer:</u> The volume of stock solution of calcium chloride required is 10 mL.
<u>Explanation:</u>
A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.
To calculate the amount of solute needed, the formula used is:
....(1)
where,
are the concentration and volume of stock solution of calcium chloride
are the concentration and volume of diluted solution of calcium chloride
Given values:
Plugging values in equation 1:
Hence, the volume of stock solution of calcium chloride required is 10 mL.
