Answer:

When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion

Some compounds are described as binary compounds what does this mean

zubka84 [21]

Answer:

It means these compounds are only made up of two elements.

Explanation:

Binary compounds:

The compounds which are made up of the atoms of only two elements are called binary compounds.

For example:

The following compounds are binary:

HCl

H₂O

NH₃

HCl is binary because it is composed of only hydrogen and chlorine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.

water is also binary because it is also made up of only two elements hydrogen and oxygen.

While all polyatomic compounds are not binary. for example,

H₂SO₄

It is made up of hydrogen, sulfur and oxygen. There are three elements are present in this compound. So, it is not binary compound.

Are the following solutions acidic, basic, ot neutral.

Slav-nsk [51]

Answer:

1) Basic

2) Basic

3) Acidic

Explanation:

pH of a solution is a measure of the H3O+ ions in the solution and hence reflects its acidity.

$pH = -log[H3O+]$

Solutions are classified as acidic, basic or neutral based on the pH range

-pH < 7, acidic

- pH = 7, neutral

- pH > 7, basic

1) [H3O+] = 2.5*10^-9M

$pH = -log[H3O+]=-log[2.5*10^{-9}]=8.60$

Since pH > 7, solution is basic

2)[OH-] = 1.6*10^-2M

$pOH = -log[OH-]=-log[1.6*10^{-2}]=1.80$

pH = 14 - pOH = 14 - 1.80 =12.2

Since pH > 7, solution is basic

3) [H3O+] = 7.9*10^-3M

$pH = -log[H3O+]=-log[7.9*10^{-3}]=2.10$

Since pH < 7, solution is acidic
