Answer:
386.75 grams
Explanation:
You can use dimensional analysis to help you solve for this question
1. set up a proportion
<u> x grams</u>
4.25 mol x x mole
2. to find the amount of grams/mol that are in NiS we find the gram formula mass (mass of all the atomic masses of each element)
Ni- 59 grams
S- 32 grams
add these together and you get 91 g/mol
3. now plug in the values and multiply across
<u> 91 grams </u>
4.25 mol x 1 mole
when you multiply across this is equal to 386.75 grams

Answer: You need a control group because......
Explanation: You need a control group in order to study if there is any difference in behavior between two groups when an external stimulant is introduced.
Answer:In order for a molecule to have polarity it must have an electronegativity difference of 0.5-1.7. There is polarity within sucrose because of oxygen-hydrogen and oxygen-carbon. Oxygen-hydrogen is polar because a electronegativity of 1.2 is created (O=3.4 H=2.2-----> 3.4-2.2=1.2); this is a polar molecule.
Explanation:
By hot springs, fumaroles and geysers.
