A & C.
much debated nuclear power plants uses nuclear fission power stations, with uranium-235 as the source if fission. It is "non-renewable" according to the Energy Information Administration.
burning wood is also a non-renewable energy source
Answer:
1 At 0C° KNO3 is least soluble
2 Approximately 65 grams
3 About 30 grams
4 yes it increases at the same rate can be explained by straight line graph
Explanation:
Significant figures are numbers that are not 0s, but they are included if they are between two numbers:
There are three significant figures, 304
Hope this helps! :)
Answer:
Explanation:
Given that:-
Moles of K = 1.10 moles
Moles of Te = 0.55 moles
Moles of O = 1.65 moles
Taking the simplest ratio of the moles of the elements as:-
K : Te : O
1.10 : 0.55 : 1.65
2 : 1 : 3
Empirical formulas is the simplest or reduced ratio of the elements in the compound. So, the empirical formula is:-
Answer:
77%
Explanation:
First we <u>convert 3.0 g of cyclohexanol (C₆H₁₂O) to moles</u>, using its <em>molar mass</em>:
- Molar mass of C₆H₁₂O = 100.158 g/mol
- 3.0 g ÷ 100.158 g/mol = 0.030 mol
Then we <u>convert 1.9 g of cyclohexene (C₆H₁₀) to moles</u>, using its <em>molar mass</em>:
- Molar mass of C₆H₁₀ = 82.143 g/mol
- 1.9 g ÷ 82.143 g/mol = 0.023 mol
Finally we <u>calculate the theoretical yield</u>:
- 0.023 mol / 0.030 mol * 100% = 77%
