Why is knowing the density of water important to us? Give a reasonable answer
Ahat [919]
Measuring density is very important for many different industries because the density measurement will help determine the characteristics of a material, for example, whether the material will float or sink. Knowing the density of a material helps in determining the mass and volume of a material, all of which are extremely important measurements in all industries.

How many moles are in 187.54 grams of magnesium chlorate?
Svetlanka [38]

Hey there!

Magnesium chlorate: Mg(ClO₃)₂

Find molar mass.

Mg: 1 x 24.305 = 24.305

Cl: 2 x 35.453 = 70.906

O: 6 x 16 = 96

------------------------------------

                      191.211 g/mol

We have 187.54 grams.

187.54 ÷ 191.211 = 0.9808

There are 0.9808 moles in 187.54 grams of magnesium chlorate.

Hope this helps!

Which best explains what happens to the carbon atoms in carbon dioxide during photosynthesis?A They are incorporated into molecu
Mademuasel [1]

Answer:

A They are incorporated into molecules of sugar.

Explanation:

Photosynthesis is the metabolic process whereby sugar molecules are synthesized by plants in the presence of sunlight (light energy). For this process to occur, carbon dioxide (CO2) and water (H2O) are needed as reactants from external sources. Hence, the photosynthetic equation is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

According to this question, the carbon atoms in carbon dioxide are incorporated into sugar molecule (glucose). It takes 6 carbon atoms to produce one glucose molecule (C6H12O6). This process involves series of reaction in the light-independent stage of photosynthesis to occur.
