No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)

6 0

Explanation:

Number of moles are defined as the mass divided by molar mass.

Mathematically,       No. of moles = \frac{mass}{\text{molar mass}}

It is given that mass is 55.98 g and molar mass of CF_{2}Cl_{2} is 120.91 g/mol.

Therefore, calculate the number of moles as follows.

              No. of moles = \frac{mass}{\text{molar mass}}

                                   = \frac{55.98 g}{120.91 g/mol}

                                   = 0.462 mol

Thus, we can conclude that there are 0.462 moles present in 55.98g of CF_{2}Cl_{2}.

Hello, I need some help writing a paragraph about the water cycle! If u can write a paragraph EXPLAINING the water cycle i would
Serhud [2]

Answer:

The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. Hope this helps, mark as brainliest please!

Deuterium is the isotope of hydrogen of mass number 2, with a proton and a neutron in its nucleus. The chemistry of deuterium is
s344n2d4d5 [400]

Answer:

True

Explanation:

We know that the zero-point-energy of a C-D system is quite lower than the zero point energy of the C-H bond so the C-D bond is stronger.

Kinetic isotope effect refers to the change in the rate of reaction owing to a change of one of the atoms of the reactants by replacing it with one of its isotopes.

Since we know that the C-D bond is stronger than the C-H bond, when we replace hydrogen with deuterium in a reaction's rate determining step we experience a little lag in the rate of reaction. This is referred to as the kinetic isotope effect in physical organic chemistry.

Why are some elements no longer found on earth
Iteru [2.4K]

Answer:

A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".

Explanation: hope that helps
