Answer:

D

Explanation:

The statement in the question above gives the statement of the law of conservation of matter. The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.

This particular law is talking about the indestructible nature of matter. Whatever form of matter we have presently was as a result of the fact that it was converted to from one initial form. It is this fundamental law that guides the operation of a wide number of scientific operations. Things like reaction between substances to form entirely or partially new substances are guided by these fundamental laws of nature

How many moles are there in 24.0 grams of FeF3
Sphinxa [80]

Hey there!:

Molar mass FeF3 = 112.84 g/mol

Number of moles  = mass of solute / molar mass

Number of moles = 24.0 / 112.84

Number of moles = 0.212 moles of FeF3


Hope that helps!

Which tiny, round “factory” puts together protein and is often found in the endoplasmic reticulum?
hodyreva [135]
<span>In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, and protein combine to form a nucleoprotein called a ribosome. The ribosome serves as the site and carries the enzymes necessary for protein synthesis. They are often takes the shape of small round particles attached in the endoplasmic reticulum. The ribosome attaches itself to m-RNA and provides the stabilizing structure to hold all substances in position as the protein is synthesized. Several ribosomes may be attached to a single RNA at any time.  <span> </span></span>

A sample 0. 100 moles of a gas is collected at at stp. What is the volume of the gas in liters?
andrew11 [14]

A sample 0. 100 moles of a gas is collected at at STP . 2.24 is the volume of the gas in liters.

The STP means standard temperature and pressure.

At STP,

Temperature = 0 °C =273 K

Pressure = 1 atm

We get value of volume by using ideal gas equation,

PV = nRT

  • P is the pressure of the gas = 1 atm
  • V is the volume occupied by the gas = ?
  • n is the number of the moles = 1 mole
  • T is the temperature of the gas = 273 K or  0 °C
  • R universal gas constant = 8.31 J/ mole × K

Calculation,

Since, one mole of a gas occupy 22.4 L volume at STP

So, for 0.1 mole volume occupy = 22.4L × 0.1 mole/1 mole =  2.24L

To learn more about volume at STP,
