Answer:

The removal of one or more electrons from a neutral atom results in a cation.

Explanation:

When you remove electrons from a neutral atom, the atom becomes more positive. Electrons have a negative charge and the protons inside of the nucleus have a positive charge. When electrons are removed, the positive charges from the protons outweigh the negative charges. This results in a positively charged atom, called a cation.

it takes 60 days for 1024 grams of element XY to decay to 32 grams. what is the half life of element XY

KonstantinChe [14]

Answer:

The half life of element XY is 12 days

Explanation:

Given:

Time taken for 1024 grams to decay into 32 grams = 60 days

To Find:

The half life of element XY = ?

Solution:

The Half life is calculated by

$N = N_0 (\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}$

$t_{\frac{1}{2}}$ = $\frac{t}{log_{\frac{1}{2}}( \frac{N(t)}{N_0})}}$

Substituting the values,

$t_{\frac{1}{2}}$ = $\frac{60}{log_{\frac{1}{2}}( \frac{32}{1024})}}$

$t_{\frac{1}{2}}$ = $\frac{60}{log_{\frac{1}{2}}(0.03125)}}$

$t_{\frac{1}{2}}$ = $\frac{60}{5}$

$t_{\frac{1}{2}}$ = 12

PLEASE! :( Two aqueous solutions of AgNO3 and NaCl are mixed. Which of the following diagrams best represents the mixture? For s

-BARSIC- [3]

Answer:

NaCl + Ag(NO₃) --> Na(NO₃) + AgCl

Explanation:

Chemical equation:

NaCl + Ag(NO₃) --> Na(NO₃) + AgCl

The given reaction represent the double displacement reaction. Anion and cation of both reactant exchange with each others.

The anion of sodium chloride(Cl⁻) combine with cation of silver nitrate Ag⁺ and NO₃⁻ combine with Na⁺.

The third equation is correct while others are in correct.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD
