Answer:
Stirring will help cool a hot drink because it speeds up the process of convection by bringing the hottest liquid at the bottom to the top
Explanation:
Answer:
Option A
Explanation:
Addition of too much of solvent will make the solution dilute due to which the crystals will not form. Hence option D is incorrect
On the other hand adding a minimum amount of boiling solvent will give a saturated solution for recrystallization. Hence, option A is incorrect
Addition of cold solvent will lower the rate of formation of crystals. Hence, both option B and C are incorrect
Answer: if the temp of the ground water from a seismic vent is actually 30 celcius then it would totally have enough energy to heat to room temperature which is close to half that temperature
you could simply pump the water through a forced air system and the air would absorb heat energy from the water that is circulated through and the air would leave warmer than when it came in. it doesn't need to be increased by 30 degrees celcius, that is likely the sticking point for him
Explanation:
Answer:
12.78
Explanation:
pOH= -log(0.0600) = 1.22184875
pH= 14-1.22184875 = 12.78
Answer:
The answer is
<h3>1.204 × 10²⁴ atoms of B</h3>
Explanation:
To find the number of entities of a substance given it's number of moles we use the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 2.0 moles
We have
N = 2 × 6.02 × 10²³
We have the final answer as
<h3>1.204 × 10²⁴ atoms of B</h3>
Hope this helps you
