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.

What is silicons reactivity level

egoroff_w [7]

Answer:

this is your answer

Explanation:

Silicon, like carbon, is relatively inactive at ordinary temperatures; but when heated it reacts vigorously with the halogens (fluorine, chlorine, bromine, and iodine) to form halides and with certain metals to form silicides.

What information is needed to determine the amount of moles in 1.6g of HCL?

alukav5142 [94]

Answer:

Molar mass and Mass

Explanation:

The relationship between mass and number of moles is given as;

Number of moles = Mass / Molar mass

Mass = 1.6 g

Molar mass of HCl = ( 1 + 35.5 ) = 36.5 g/mol

Number of moles = 1.6 g / 36.5 g/mol

Number of moles = 0.0438 mol

Soil is a renewable resource if properly maintained. Which of the following helps to maintain healthy soil?

brilliants [131]

C. crop rotation

Explanation:

Crop rotation is a farming practice that is commonly used to maintain a healthy soil.

This practices helps to conserve and appropriate a soil for the best use.

During crop rotation, different crop species are planted during a growing season. The patterns are designed to cultivate both crops that replenish and deplete the nutrients in soil.

Through this the fertility of the soil is sustained all year round.

This helps to avoid the use of pesticides on crops.

When the following equation is balanced, what is the coefficient for CaCl2 ?

USPshnik [31]

To know if an equation is balanced you need to check and see how much of each molecule is on either side of the arrow. Right now you have 1-Ca, 2-H, 2-Cl on the left side of the arrow and 1-Ca, 2-Cl, and 2-H on the right side too. Because all the molecules are equal on both sides this means that the equation is balanced. So in front of the CaCl2 there is an assumed coefficient of 1. The answer is 1.
