<h3>What is a monatomic ion?</h3>

An ion with only one atom is referred to as a monatomic ion or simple ion. A polyatomic ion is one that has more than one atom, even if they are all from the same element.
The metal (cation) in a type I binary ionic combination only produces one kind of ion. Metals that form multiple ions, or ions with various charges, are found in type II ionic compounds.
The term "monoatomic," which combines the words "mono" and "atomic," refers to a single atom.
A monatomic gas is a gas in which atoms are not bonded to one another. This term is typically used to describe gases.
When compared to polyatomic gases, the thermodynamic behavior of a monatomic gas is far more straightforward.

Polonium-218 undergoes beta decay, converting a neutron into a proton. Then the daughter isotope undergoes another beta decay, a

sergij07 [2.7K]

Answer: $^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$ is the correct equation for beta decay.

Explanation:

When a beta particle, that is, $^{0}_{-1}e$ is emitted in a radioactive decay then it is known as beta decay.

Therefore, beta decay of Polonium-218 is as follows.

$^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$

Therefore, we can conclude that $^{218}_{84}Po \rightarrow ^{218}_{85}At + ^{0}_{-1}e$ is the correct equation for the given beta decay.

Calcium carbonate forms limestone, one of the most common rocks on Earth. It also forms stalactites, stalagmites, and many other

max2010maxim [7]

Answer: $CaCO_3(s)\rightarrow CaO(s)+CO_2(g)$ , 0.533 L

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$CaCO_3(s)\rightarrow CaO(s)+CO_2(g)$

According to avogadro's law, 1 mole of every substance occupies 22.4 L of volume at STP.

Number of moles = $\frac{\text {given mass}}{\text {Molar mass}}$

moles of calcium carbonate = $\frac{2.38g}{100g/mol}=0.0238mol$

As 1 mole of calcium carbonate produces = 22.4 L of carbon dioxide at STP

Thus 0.0238 moles of calcium carbonate produces = $\frac{22.4 L}{1}\times 0.0238=0.533L$ of carbon dioxide at STP

The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of Ba3N2 req

a_sh-v [17]

Answer:

c 3 mol of Ba(OH)₂ and 1 mol of Ba₃N₂ should be interchanged

Explanation:

Ba₃N₂ + 6H₂O → 3Ba(OH)₂ + 2NH₃

n/mol: 9.2

$\text{Moles of Ba$_{3}$N}_{2} = \text{9.2 mol Ba(OH)}_{2} \times \dfrac{\text{1 mol Ba$_{3}$N}_{2}} {\text{3 mol Ba(OH)}_{2}}= \text{x mol Ba$_{3}$N}_{2}$

They want to find moles of Ba₃N₂, so that should be in the numerator of the conversion factor,

Moles of Ba(OH)₂ should be in the denominator to cancel the units in 9.2 mol Ba(OH)₂,

How do atoms and elements differ from each other?

strojnjashka [21]

Answer:

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
