A piece of metal weighing 267.0 g is placed in a graduated cylinder containing 229.0 mL of water. The volume of water now reads

densk [106]

Answer:

9.368g/mL

Explanation:

The density is defined as the mass of a compound in a determined volume.

Based on Archimedes' law, the volume of the piece of metal is the difference between the volume of the water + the inmersed piece - the original volume of water. That is:

Volume of the metal:

257.5mL - 229.0mL = 28.5mL

As the mass of the metal is 267.0g; its density is:

Density:

267.0g / 28.5mL =

When 2,2-dimethylbutane is subjected to free-radical chlorination, ________ distinct monochlorinated products are possible and _

malfutka [58]

Answer:

See the explanation

Explanation:

In this case, we have to remember that in the monochlorination products we only have to add one "Cl" with this in mind, we can have several options.

a) 1-chloro-2,2-dimethylbutane

b) (R)-3-chloro-2,2-dimethylbutane

c) (S)-3-chloro-2,2-dimethylbutane

d) 1-chloro-3,3-dimethylbutane

Additionally, from these 4 molecules, we will have 2 enantiomers. (R)-3-chloro-2,2-dimethylbutane and (S)-3-chloro-2,2-dimethylbutane.

See figure 1

I hope it helps!

What can be categorized as a use of plasma in technology

Pachacha [2.7K]

Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it: solids becomes liquid, and liquids becomes gaseous. If even more energy is supplied to a gas, it is ionized and goes into the energy-rich plasma state, the fourth state of matter.ore than 99% of the visible matter in the universe is in the plasma state.
