Its pH is constant which is neither acid or base
Igoryamba3 years ago
7 0
The answer is 7.

Since pH values are made up of 14 numbers, and the smaller the number is, the more acidic a substance is, and the larger the pH value is, the more alkaline the substance is. So, the median number of the pH scale is 7. 

We can easily test the pH value of simple substances (liquid the best) by using pH paper, which you can easily get in drugstores, or pH meter, where you should be able to find in most laboratories. You'll have a chart to match with and you should get the value of 7 if it's pure water that you're testing.

Which of the following affects cell potential?
Slav-nsk [51]

Answer:

the standard cell potential value

Explanation:

For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.

However, from Nernst's equation;

Ecell= E°cell - 0.0592/n log Q

Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.

How would you describe the following chemical reaction?
GREYUIT [131]

Answer:

B

Explanation:

The normal way to express an energy reaction is to put the energy on the left. Then you can make a rule.

  • If the energy on the left is plus then the reactants require energy. The reaction is endothermic -- energy is taken from the environment.
  • If the energy is minus when it is on the left. then the reactants give up energy. The reaction is exothermic and energy is given to the environment.

2CO(g)+O2(g) - energy --> 2CO2(g)

Exothermic

What is the<br> mass of 1.82<br> moles of<br> Lithium<br> carbonate?
frutty [35]

Answer:

244.76

Explanation:

The weight of grams by 1.82 moles of lithium carbonate would be: 134.481438 So we need to use this equation to find mass by grams m × g = ms Where m is for moles, g for grams, and ms for mass. So now we need use this equation: 1.82 × 134.481438 = ? 1.82 × 134.481438 = 244.75621716 244.75621716, rounded-up (to the nearest-tenths place) is 244.76. So now you have it! The mass of 1.82 moles of lithium carbonate is 244.76!
