Write a balanced nuclear equation for the alpha decay of titanium-45.
schepotkina [342]

Explanation:

20984Po→20582Pb+42α

4520Ca→4521Sc+0-1e+00ν

Explanation:

The alpha decay of polonum-209, which consists of the emission of an alpha particle, will leave behind the atom of a different element.

Notice that the identity of the element changes after the decay. This means that you're dealing with a nuclear transmutation, a process that converts an atom of a given element into an atom of a different element.

What is the noble gas configuration for telleurium
Maru [420]

[Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.

<h3>What is telleurium?</h3>

Tellurium is a noble gas element that is non-reactive in nature due to complete outermost shell. It has atomic number of 52 which means that it has 52 number of electrons.

So we can conclude that [Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.

Wear _______________________ when handling batteries, because they can explode or leak.
Basile [38]

The answer is: b. Safety glasses and acid-resistant gloves.

Battery acid (sulfuric acid) has pH = 0.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).  

Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.
