92 U 232 92 U 238

In these uranium samples the electron and protons are the same = 92

but in first isotope the neutrons are =232-92=140

in case of second the neutrons are =238-92=146

now you can answer this question !

The answer is;  They each have the same number of protons

All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234.

Which type of nuclear decay is the radioactive isotope fe2659 likely to undergo?
jekas [21]

Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.

Fe_{26} ^{59} → Co_{27} ^{59} +\beta_{1}  ^{0}

It can be seen that after the beta minus decay Fe changes into Co.

In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.

Neutron-rich nuclei often decay by producing both an electron and an antineutrino.

Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

List the five characteristics a substance must have to be a mineral. Explain why coal and a glass marble are not minerals.
Bumek [7]
- Naturally occurring
- Inorganic
- Solid
- Definite chemical composition
- Ordered internal structure
A mineral has to be naturally occurring. Coal is not a mineral because it is carbon-based and comes from fossilized plants. Glass is non-crystalline solid.

Red mercury (II) oxide decomposes to form mercury metal and oxygen gas according to the following equation: 2HgO (s) 2Hg (l) + O
diamong [38]

hey there!:

2HgO (s) =>  2Hg (l) + O2 (g)

2 moles of HgO decompose to form 2 moles of Hg and 1 mole of O2 according to the reaction mentioned in the question.

So 4.00 moles of HgO must give 4 moles of Hg and 2 moles of O2 theoretically.

603 g of Hg = 603 / 200.6 = 3 moles

Percent yield = ( actual yield / theoretical yield) * 100

= ( 3/4) * 100

= 75 %

Hope this helps!

The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.
