Answer:
24 a 2.85
Explanation:
HCl is a powerful acid so it completely ioniz in water
Answer:
1.43*10 to the power of -10
Explanation:
Since 1.43*10 to the power of -10 is nothing else but
1.43/10¹⁰ which is equal to the number in the question
It is not 10¹⁰ because it will increase the number of zeros to the right
but we need to increase it towards the left
Hope this helps
She will most likely observe that the temperature
does not change during melting because the heat absorbed is used to overcome
intermolecular forces rather than to increase the kinetic energy of the
particles if she measures the temperature of the water in the beaker.
Answer:
0.0226
Explanation:
Given data:
Mass of water = 0.406 g
Molar mass of water = 18.0 g/mol
Number of moles = ?
Solution:
Number of moles = mass/ molar mass
Number of moles = 0.406 g / 18.0 g/mol
Number of moles = 0.0226 mol
The answer with out units and three significant figures is 0.0226. In this value the significant figures are 226.
The Answer is D Why Because<span> clearly, including a scenario of the second and third steps as proof!!</span>
