Answer:
The voltage delivered by a primary battery is unrelated to its size.
Po, (218, 84) - Alpha Particle (4, 2) = (218 - 4, 84 - 2) = <span>(214 , 82)</span>
(214 , 82) - 2Beta = (214, 82 - 2*(-1)) = (214 , 84)
Polonium has atomic number of 84.
So answer = Polonium-214
The constant variable is the math problems, the dependent variable is the calculators, and the independent variables are the students
Element Oxidized: S (S^(2-) --> S⁰)
Element Reduced: N (N^(5+) --> N(2+))
Oxidizing Agent: HNO3
Reducing Agent: H2S
Answer:
3.918 mol Al
Explanation:
To convert between moles and grams, you have to use the molar mass of the substance. The molar mass of aluminum is 26.98 g/mol. You use this as the unit converter.
Round the number to the lowest number of significant figures; 3.918 mol Al
