When peroxide is swallowed, it generates oxygen bubbles in the stomach. Drinking higher concentrations of hydrogen peroxide can be very dangerous because it can cause tissue burns.
<u>Answer:</u> The volume of concentrated solution required is 42 mL
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated solution
are the molarity and volume of diluted solution
We are given:
Putting values in above equation, we get:
Hence, the volume of concentrated solution required is 42 mL
Answer:
Properties of Metals:
- Shiny
-Malleable
-Good Conductors of electric current
- Good conductors of heat
Properties of Non-metals:
- Dull
- Not Malleable
- Bad conductors of electric current but good electric insulators
- Poor conductors of heat
Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.
Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons. ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
Electrons per shell: 2, 8, 5
hope this helps x
would love to have brainliest! :)
