8 0
Answer is: there is 1,368·10²⁵ atoms of carbon.
N(C₃H₈) = 4,56·10²⁴.
From molecular formula: in one molecule of propane there is three atoms of carbon:
N(C) = 3 · 4,56·10²⁴.
N(C) = 1,368·10²⁵.

Which of the following is true: A. Gamma rays are too dangerous to be used in a medicinal way. B. Gamma radiation is used common
ratelena [41]

Answer:

D

Explanation:

Gamma radiation penetrates the cell wall of prokaryotic organisms such as bacteria and can inhibit their metabolic functions as well as destroy their DNA.

Debunking the other answers:

A is incorrect as Gamma radiation is used in the treatment of cancer via radiotherapy.

B is incorrect as Gamma rays are too small and would just penetrate any smoke particles.

C is incorrect because Gamma rays are used to disinfect food products to prevent food borne illness. Irradiation is safe to use on food and does not make it radioactive.

Thus, D is correct.

If the decomposition of a sample of k c l o 3 kclox3 produces 3. 29 g of o 2 ox2 , what was the mass (g) of the original sample?
____ [38]

The mass (g) of the original sample after decomposition is 8.3983 g.

A decomposition reaction can be described as a chemical reaction wherein one reactant breaks down into or extra merchandise.

explanation:

Reaction          2KClO₃ ⇒ 2KCl + 3O₂

moles               2               2            3

molar mass    122.55        74.55    32

Given, Mass of O₂ = 3.29g ⇒ moles of O₂

                                            =  (3.29/32) = 0.1028

3 moles of O₂  produced by 2 moles of KClO₃

Therefore, 0.1028 moles of O₂  produced by (2*0.1028/3) = 0.06853 moles of Kclo₃

Mass of KClo₃ in original sample is = moles * molar mass

                                                        = 0.06853 * 122.55

                                                       = 8.3983 g

A decomposition response occurs whilst one reactant breaks down into or extra merchandise. this may be represented through the general equation: XY → X+ Y. Examples of decomposition reactions consist of the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Considering how small atoms are, what are the chances that at least one of the atoms exhaled in your first breath will be in you
STatiana [176]

The answer is very probable because of how incredibly small atoms are

Very probable because of how incredibly small atoms are the chances that at least one of the atoms exhaled in your first breath will be in your last breath.

Hydrogen and oxygen always react in a 1:8 ratio by mass to form water. early investigators thought this meant that oxygen was 8 times more massive than hydrogen.

If you say that something is probable, you mean that it is likely to be true or likely to happen.

Everything around us is made up of really tiny molecules. However, such molecules are constructed from much smaller atoms. Then, even smaller protons, neutrons, and electrons are used to build those atoms. Quarks, which are even smaller particles than protons, make up protons.

The smallest unit of substance that may be disassembled without ejecting any electrically charged particles is the atom. The smallest piece of substance that displays an element's distinctive qualities is an atom. As a result, the atom serves as the basic unit of chemistry.
