Answer:

Nuclear reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide during operation. However, processes for mining and refining uranium ore and the production of reactor fuel all require a large amount of energy. Nuclear plants create more jobs than other forms of energy. 7 They create 0.5 jobs for every megawatt hour of electricity produced. This is in comparison to 0.19 jobs in coal, 0.05 jobs in gas-fired plants, and 0.05 in wind power. As a result, new gas-fired power plants were built from 1992 to 2005. an Advantages of nuclear energy Low-cost energy. Although building nuclear power plants has a high initial cost, it's relatively cheap to produce energy from them and they have low operating cost.

If you burn 46.6 g of hydrogen and produce 416 g of water, how much oxygen reacted

Bond [772]

Answer:

369.4 g.

Explanation:

The chemical reaction of reacting hydrogen with oxygen to produce water is:

H₂ + 1/2 O₂ → H₂O.

From the law of conservation of mass states that the mass does not destroyed or created from nothing but it can converted from from to another one.

The mass of the reactants = the mass of the products

∴ The mass of hydrogen + the mass of oxygen = the mass of water.

∴ The mass of oxygen = the mass of water - the mass of hydrogen = (416.0 g) - (46.6 g) = 369.4 g.

6) A 14.5 g sample of sodium chloride reacts with excess fluorine gas according to

Ann [662]

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 10.42 g.

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 8.81 g.

The given parameters;

mass of the sodium chloride, = 14.5 g
2NaCl(s) + F2(g) → 2NaF(s) + Cl2(g)

In the reaction above, we can deduce the following;

molecular mass of 2Nacl = 2(58.44) = 116.88 g

molecular mass of 2NaF = 2(42) = 84 g

molecular mass of Cl2 = 71 g

The mass of sodium fluoride produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 84 g of NaF

14.5 g of NaCl ------------------- ?

$= \frac{84 \times 14.5}{116.88} \\\\= 10.42 \ g$

The mass of chlorine gas produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 71 g of Cl2

14.5 g of NaCl ------------------- ?

$= \frac{14.5 \times 71}{116.88} \\\\= 8.81 \ g$
