I think its evaporate
Explanation:
because when the heat absorbed the chemicals evaporate
Answer:
A positive ion has more protons than electrons and a negative ion has more electron ions
So the answer is
A positive ion has less electrons and a negative ion has more electrons
Answer:
The balanced chemical equation is given as:
Explanation:
When potassium hydroxide reacts with phosphoric acid it gives potassium phosphate and water as a products.
The balanced chemical equation is given as:
According to reaction, 3 moles of potassium hydroxide recats with 1 mole of phosphoric acid to give 1 mole of potassium phosphate and 3 moles of water.
Answer:
The answer is B or A
Explanation:
All the other ones don't work
Answer:
Explanation:
Hello,
In this case, we can consider the n-propanol as the solute (lower amount) and the t-butanol as the solvent (higher amount), for which, initially, we must compute the moles of n-propanol (molar mass = 60.1 g/mol) as shown below:
Since the molality is computed via:
Whereas the mass of the solvent is used in kilograms (0.0130g for the given one). Thus, we compute the resulting molality of the solution:
Or just:
Best regards.
