Concentrated hydrochloric acid is an aqueous solution that is 34.70 % HCl. The density of the solution is 1.19 g/mL. What mass o

The mass of HCl that is contained in the solution is 147 g HCl

Why?

To find the mass of HCl we have to apply what is called a conversion factor. In a conversion factor we put the units we don't want at the bottom, and the ones we want at the top.

For this question, we want to go from liters of solution to mass of HCl, and the conversion factor is laid out as follows:

0.356Lsolution*\frac{1000mL}{1L}*\frac{1.19 g solution}{1 mL solution}*\frac{34.70 g HCl}{100 g solution}=147 g HCl

Have a nice day!

52. Classify each compound as ionic or molecular. If it is ionic,
Darina [25.2K]

Answer:

Explanation:

1...............

CoCl₂ is an ionic compound

CF₄ is molecular

BaSO₄ is an ionic compound

NO is molecular

An ionic compound is a compound which forms between a metal and non-metal. It involves the formation of a bond between two ions of significant electronegative difference. It results from the electrostatic force of attraction between two atoms in which one has lost an electron(metal) and the other that has gained an electron(non-metal).

     CoCl₂ is an ionic compound

     BaSO₄ is also ionic

A molecular compound is formed as a result of covalent bonds between atoms. This is due to the fact that the two atoms have similar electronegativities and would both pull the shared electrons closely. Most molecules are usually formed this way.

      CF₄ and NO are both molecular compounds

2...... The ionic compounds are the ones containing metals:

         In CoCl₂ the metal is Co, cobalt

             BaSO₄ has Ba

 Co is a transition metal. Transition elements are known to have various oxidation states. This implies that they can form more than one type of ion. The oxidation number of Co are -1, 0, +1, +2, +3 and +4

 Ba will only form one type of ion as an alkaline earth metal. It has an oxidation state of +2 only. It will only form one type of ion.

Bad White [126]

Independent variable: calculators, computers

Dependent variable: speed

3 constants: seat, atmospheric condition, and time.

Control: none

<h3>What are variables</h3>

Variables are of different types in experiments. They can be:

  • Independent: a variable that is supplied by the researcher and which can be tweaked among different experimental groups to produce different outcomes.
  • Dependent: variables whose value is dependent on the kind of independent variable supplied by the researcher. It is the actual variable that is measured during the course of experiments.
  • Constant: all other variables that are kept the same among experimental groups.

Thus, in this case, the independent variable will be the calculator or computer/calculator combination given to the two groups.

The dependent variable will be the speed at which each group finished solving the math problems.

The constant variable will be all other variables supplied to the two groups.
