Answer:
<h2>2.57 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
volume = final volume of water - initial volume of water
volume = 22.76 mL - 15.35 ml = 7.41 mL
We have the final answer as
<h3>2.57 g/mL</h3>
Hope this helps you
Answer : The correct option is, 12.40
Explanation : Given,
Concentration of ion = 0.025 M
First we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH of a solution is, 12.40
Answer:
The numbers of moles in 20.0g of NaOH:
n= = = (moles)
While voltage does pose a threat, it's mostly the current that causes damage. There must be voltage available to motivate electrons to flow through a victim. Resistance to current causes (in the case of the victim being human or having flesh) burnt tissues, muscles freezes, and fibrillates hearts.
Answer: Non-polar covalent bond
Explanation: If two atoms have no difference between their electronegativity charges, they will form nonpolar covalent bonds. This means that the electrons will be shared with the same intensity.
