4 neutrons that are produced along with the Zn and sm. The complete final equation is:  ²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n

<h3>What atomic mass?</h3>

Atomic mass, the quantity of matter contained in an atom of an element.

1) In the left side of the transmutation equation appears:

²³⁵U + ¹n →

Deleting the atomic number (subscript to the left) because the question does not show them as it is focused on a number of neutrons.

2) The right side of the transmutation equation has:

→ \;^{72}Zn+\;^{160}sm +?

3) The total mass number of the left side is 235 + 1 = 236

4) The total mass number of Zn and sm on the right side is 160 + 72 = 232

5) Then, you are lacking 236 - 232 = 4 unit masses on the right side which are the 4 neutrons that are produced along with the Zn and sm.

The complete final equation is:

²³⁵U + ¹n → \;^{72}Zn+\;^{160}sm + 4 n

1.) You have 4.2 moles of magnesium (Mg). How many atoms of magnesium do you have?
NNADVOKAT [17]
1) N = 4,2 moles
M = 24,31 u
m = N x M
= 4.2 x 24.31 = 102.102 kg


2) m = 54.9 grams = 0.0549 kilograms
M (Na) = 22.99 u
N (moles) = m / M
N = 0.0549 / 22.99 = 2.4 x 10^-3 moles

I don’t know if it helped you a bit :)

When reacted with elemental chlorine at room temperature, liquid phosphorous trichloride (PCl3) is converted to solid phosphorou
Sergeu [11.5K]

PCl₅ reacts upon contact with water to launch hydrogen chloride and supply phosphorus oxides. the primary hydrolysis product is phosphorus oxychloride     PCl₅ + H₂O ========>  POCl₃ + 2HCl.

Phosphorus trichloride appears as a colorless or slightly yellow fuming liquid with a pungent and irritating odor resembling that of hydrochloric acid. Causes severe burns to skin, eyes and mucous membranes.

Divide the mass of the material through its molar mass. The molar mass of a substance is the mass in grams of 1 mole of that substance. This mass is given via the atomic weight of the chemical unit that makes up that substance in atomic mass units.

One mole is described as the amount of substance containing as many number one entities atoms, molecules, ions, electrons, radicals, and lots of others. As there are atoms in 12 grams of carbon - 12(6. 023×10²³. The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
