The movement of fluid materials caused by density differences
Dovator [93]
This movement is known as convection or convection currents. This occurs due to the fact that warmer fluid is of lower density than colder fluid. This causes warmer fluid to rise and colder fluid to sink. This creates circulatory currents within the body of the fluid.

These traits describe either a chemical or a nuclear reaction. Which statements describe a nuclear reaction? Check all that appl
Ugo [173]

The statements that describe a nuclear reaction are may involve a change in total mass, involve very high-energy changes, and involve changes in nuclides when decay takes place.  

There are two kinds of nuclear reactions, that is, fission and fusion. Fusion involves the fusion of two light atoms into a heavier atom, while fission involves the splitting of an unstable isotope (with a high mass number) into stable elements of lower mass number, which vary in features from the parent atoms. Both the reactions discharge huge concentration of energies in the process.

What is the concentration in molarity of S2O32- (aq) in a solution prepared by mixing 150 mLmL of 0.149 MM Na2S2O3 (aq) with eno
Artist 52 [7]

Answer:

0.0890 M

Explanation:

Since the concentration of KCl is irrelevant in this case, the concentration of Na2S2O3 can be determined using a simple dilution equation:

C1V1 = C2V2, where C1 = 0.149 M, V1 = 150 mL, V2 = 250 mL

C2 = 0.149 x 150/250

                    = 0.089 M

To determine the concentration of  S2O32- (aq), consider the equation:

Na_2S_2O_3  => 2Na^+_{(aq)} + S_2O^2^-_3_{(aq)}

The concentration of Na2S2O3 and S2O32- (aq) is 1:1

Hence, the concentration in molarity of S2O32- (aq) is 0.089 M.

To 3 significant figures = 0.0890 M

What is the empirical formula of a compound containing carbon, hydrogen, and oxygen in the ratio 14:42:84?
Alexxandr [17]
<h3>Answer:</h3>

D. CH₃O₆

<h3>Explanation:</h3>
  • We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84

We are supposed to determine the empirical formula of the compound;

  • We need to know what is an empirical formula;
  • An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.

In this case;

The ratio of C : H : O is 14 : 42 : 84

  • Note, this is not the simplest ratio.

But we can simplify further to get the simplest whole number ratio;

  • Therefore, 14 : 42 : 84  is equal to 1 : 3 : 6
  • Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
  • Therefore, the empirical formula of the compound is CH₃O₆
