In this equation, what should be the coefficients of the reactants and products?
Strike441 [17]

Answer:

C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2

Explanation:

An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.

The unbalanced reaction:

I₂ + O₂ -----> I₄O₉

<u>Reactants</u>: 2 iodine, 2 oxygen

<u>Products</u>: 4 iodine, 9 oxygen

The balanced equation:

4 I₂ + 9 O₂ -----> 2 I₄O₉

Reactants: 8 iodine, 18 oxygen

Products: 8 iodine, 18 oxygen

Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.

The three types of nuclear radiation in increasing order of penetrating power are ____.
cricket20 [7]

Answer:

The three types of nuclear radiation in increasing order of penetrating power are ____.

alpha, beta, gamma

Explanation:

Alpha Ray: This has the least penetrating power because the particles produced during decay are large in  quantity but they have a very low energy which dosent alow them to move far through space because the are ususally blocked.

Beta ray : they have more penetrating power than alpha rays because they a bit higher in energy and quantity {size}

Gamma Ray;  this has the most penetrating power. they are highly powerful  waves but do little at ionization of other atoms or molecules.  it penetrates through molecules very easily due to its size and energy.

In the periodic table, the elements that are adjacent to the "stair step" are called _____. actinide series nonmetals metalloids
yawa3891 [41]

Answer:-

Metalloids

Explanation:-

The stair step line is a line in the periodic table that divides the metals on one side and the non metals on the other side. So the elements which lie on the stair step line must have properties in between those exhibited by the metals and those by the non metals.

Such elements we know are called metalloids. Thus In the periodic table, the elements that are adjacent to the "stair step" are called metalloids.
