Answer:

A) increase Ph B) incorporated ions: Na⁺ and ClO⁻

Explanation:

Bleach is the regular name for sodium hypochlorite (NaClO). This salt is basically composed by the cation sodium (Na⁺) and anion hypochlorite (ClO⁻), and when dissolved in water, this salt makes Ph goes above 7, this is, a basic Ph (will be increased) - have in mind that, a Ph below 7 is acid, and a Ph above 7 is basic)

This will occur since, when ClO⁻ is dissolved in water:

ClO⁻ + H2O → HClO + OH⁻ according to this reaction, the hydroxyl anion will increase the Ph of the water

Finally, when dissolving bleach in water, you will be incorporating ions Na⁺ (sodium) and ClO⁻ (hypochlorite)

What is the mass of snow (in tons) on a 150.0ft by 45.0 ft flat roof after a 6.0 inch snowfall? Assume that 11 inches of snow is

Aneli [31]

6 inches of snowfall would be equivalent to 6/11 inches of water or 6/132 feet. So the volume of the equivalent amount of water on the roof is 150 ft. x 45 ft. x 6/132ft. = 306.8 cubic feet.
Since there are 907185 grams in a ton and 28316.8 mL in a cubic foot, 1.00 g/mL is equivalent to 0.0312 tons/cubic foot
Multiplying the two results gives 9.58 tons of snow.

The process of fermentation involves chemical reactions that convert solid glucose (C6H12O6) into aqueous ethanol and carbon dio

e-lub [12.9K]

Answer:

C6H12O6 —> 2C2H5OH + 2CO2

Explanation:

The equation for the reaction is given below:

C6H12O6 —> C2H5OH + CO2

We can balance the equation above as follow:

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

Now the equation is balanced.

KonstantinChe [14]

Answer:

avogadro's constant

Explanation:

this is the fixed number of the atoms in the molecule of an element

avogadro's law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules

that is all gases with same temperature and pressure will always have equal numbers of molecules
