Explanation:
Electrons are negatively charged. So it has a -3 charge.
amount of charge producing a field (direct)
the distance from the charge (inverse)
Answer:
Molecular formula: C₂H₄O₂
Empirical formula: CH₂O
Explanation:
40 % C, 6.72 % H and 53.29 % O states the centesimal composition of the compound. These data means that in 100 g of compound we have x grams of a determined element.
We divide the mass by the molar mass of each:
40 g / 12 g/mol = 3.33 moles of C
6.72 g / 1 g/mol = 6.72 moles of H
53.29 g / 16 g/mol = 3.33 moles of O
We can determine rules of three to get, the molecular formula.
In 100 g of compound we have 3.33 moles of C, 6.72 moles of H and 3.33 moles of O; therefore in 60 g (1 mol) we must have
- (60 . 3.33) / 100 = 2 moles of C
- (60 . 6.72) / 100 = 4 moles of H
- (60 . 3.33) / 100 = 2 moles of O
Molecular formula is C₂H₄O₂
Empirical formula has the lowest suscripts; we divide by two, so the empirical formula is CH₂O
Since the choices are not listed, it would be difficult to identify what is really the answer. The best I could do is to list some of the environmental consequences of the use of nuclear energy. This type of energy is said to have the lowest impact on the environment since it does not have eany emission that would cause air pollution, its waste is isolated from the environment and would only need a small amount of area of land. Although it has the lowest impact, it would still have an effect on the environment. One would be the amount of radiation that will be emitted when a meltdown would happen. This would affect not only the environment but all of the living things including humans. Also, it could cause eutrophication from the wastes. <span />
Answer:
2 C Atoms
Explanation:
When you have coefficient of 2 next to a compound element, it indicates there are 2 of each compound element. In the compound element, there is one C Atom, and 2×1 is 2.
