Answer:
It's more like abnormal tissue growth
Explanation:
consider it like a cancer.
When phenol is heated with zinc dust benzene is obtained.
The object with more volume is the inflated balloon
Explanation:
Volume is about how much space an object or material occupies; in this context, if the inflated balloon has the double size of the bag of marbles then the balloon has more volume because this is occupying more space.
Moreover, the volume should not be confused with other factors such as mass or weight because it is likely the marbles weight more but this does not imply the marbles have more volume. Also, the balloon contains gas and gases tend to expand and occupy more space, which does not occur with solids such as marbles because these have a defined volume.
Answer:
350.64g
Explanation:
So first you must know that M is mol/L
Next solve the problem using dimensional analysis
2L NaCl (3 mol/L) = 6 mol NaCl
After you got the number of moles you should look at your periodic table to find the molar mass
I see that it's 58.44g/mol
Use dimensional analysis again!
6 mol (58.44g/mol) = 350.64g
Don't forget to make me brainliest!
<u>Answer:</u> The density of unknown material is 7.2 g/mL
<u>Explanation:</u>
We are given:
Volume of water already in the container, = 22 mL
Volume of water rise in the cylinder, V = 27 mL
Volume occupied by unknown material =
To calculate density of a substance, we use the equation:
We are given:
Mass of unknown material = 36.0000 g
Volume of unknown material = 5 mL
Putting values in above equation, we get:
Hence, the density of unknown material is 7.2 g/mL
