Answer:

C) isotopes of the same element

Explanation:

An isomer is molecule with the same atoms as other but with a different distribution (position, optic, spacial, geometrical, etc).

This applies to molecules and not to atoms. (options A and B can't be)

The isotopes are two atoms of the same element (equal proton number) but with different mass number. This is the case of I-131 and I-133. SO option C is correct.

Also, I-131/Xe-131 and I-133/Cs-133 are two pairs of isobars (two atoms of different elements with the same mass number).

Isotopes are two atoms with the same number of protons, but a different number of neutrons. Because they have the same number of proton they are atoms of the same element, but with different masses.
so, the answer is c.
i hope this will help you

A radioactive nucleus emits a beta particle, then the parent and daughter nuclei are

Nana76 [90]

Answer:

isobars

Explanation:

How?

A radioactive nucleus emits beta particle(Like uranium,radium)
So the mass numbers are same for daughter nuclei .
They have different atomic numbes .

So they are isobars

Approximately how many moles of chlorine make up 1.79 × 1023 atoms of chlorine?

e-lub [12.9K]

1.2*10^24# atoms of chlorine

Explanation:
Chlorine gas (#Cl_2#) has two atoms of elemental chlorine in a molecule, so:
#1# mol of #Cl_2# have #6*10^23# molecules of #Cl_2#
#1# molecule of #Cl_2# have #2# atoms per molucule
Then #2*6*10^23 = 1.2*10^24# atoms of chlorine in a mol of chlorine gas

The table shows the number of reactants and products present during two separate chemical reactions.

finlep [7]

Answer:

Chemical reaction B, because the product is a compound

Explanation:

A synthesis or combination reaction is that reaction that involves combination of two or more reactants to form a single product. The two or more reactants are often elements that chemically combine to form a single compound.

In this question, two chemical reactions are involved in which chemical reaction A has 1 reactants and 3 products while chemical reaction B has 2 reactants and 1 product. Based on the explanation above, the reaction B correctly identifies the synthesis reaction because the single product is a compound.

Write the net ionic equation for the reaction between hydrocyanic acid and potassium hydroxide. Do not include states such as (a

eimsori [14]

Answer:

The net ionic equation is as follows:

HCN(aq) + OH-(aq) ----> H20(l) + CN-(aq)

Explanation:

The reaction between Hydrocyanic acid, HCN, and sodium hydroxide is a neutralization reaction between a weak acid and a strong base.

Hydrocyanic acid being a weak acid ionizes only slightly, while sodium hydroxide being a strong base ionizes completely. The equation for the reaction is given below:

A. HCN(aq) + NaOH-(aq) ----> NaCN(aq) + H2O(l)

Since Hydrocyanic acid is written in the aqueous form as it ionizes only slightly and the ionic equation is given below:

HCN(aq) + Na+(aq)+OH-(aq) ----> Na+(aq)+CN-(aq) + H2O(l)

Na+ being a spectator ion is removed from the net ionic equation given below:

HCN(aq) + OH-(aq) ----> H20(l) + CN-(aq)
