Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Although renewable energy sources, like wind and solar power, are important resources for a country’s energy mix, only nuclear power is capable of producing large amounts of electricity 24 hours a day, 365 days a year.

For safety precaution which regards to employees, several federal agencies—the US Nuclear Regulatory Commission (NRC), the U.S. Environmental Protection Agency and the U.S. departments of Energy and Transportation—establish radiation protection regulations for U.S. nuclear plants based on internationally recognized scientific studies.

For the safety precaution of power plants itself, The NRC monitors plant performance according to three strategic areas: reactor safety, radiation safety and security.

Consider the following electronegativity values:
luda_lava [24]

Answer: option C. HF

Explanation: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. Fluorine is more electronegative than hydrogen so the electrons in the bond are more closely associated with the fluorine atom than with the hydrogen atom.

What is the density of object A? Does it sink<br> or float in water?
Oksana_A [137]

Answer:

~1.5 g/cm3 and it does NOT float in water.

Explanation:

If you look at the graph, Object A weighs ~6 grams and is ~4 cm3 in volume

Density = Mass/Volume

So 6 grams/4 cm3 = 1.5 g/cm3

Water has a density of 1 g/cm3 and because Object A density is higher than that of water, it sinks.

PLS HELP: CHEMISTRY
user100 [1]

Answer:

3.59x10^21 molecules

Explanation:

1mole of a substance contains 6.02x10^23 molecules.

Therefore, 1mole of C8H18 will also contain 6.02x10^23 molecules

1mole of C8H18 = (12x8) +(18x1) = 96 + 18 = 114g.

1mole (i.e 114g) oh C8H18 contains 6.02x10^23 molecules.

Therefore, 0.68g of C8H18 will contain = (0.68 x 6.02x10^23)/114 = 3.59x10^21 molecules

Balance the equation for the reaction in which sodium oxide reacts with water to form sodium hydroxide.
tensa zangetsu [6.8K]

Answer:

➢ \: Balance \:  the  \: equation \:  for \:  the  \: reaction \\  in \:  which \:  sodium  \: oxide \:  reacts  \\ with  \: water \:  to \:  form  \: sodium \:  hydroxide.

⇒ We have Na2O + H2O --> NaOH. We have 2 sodiums and 2 oxygens and 2 hydrogens on the left side, but only one of each on the right side.

Sodium Oxide + Water → Sodium Hydroxide

⇒ Na2O + H2O → 2NaOH .

Sodium oxide is used in ceramics and glasses. Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution.
