Analyze the data and determine the actual concentration of calcium chloride in the solution. Show all calculations and report in

% wt/v concentration.
Known; Mass of CaCl2 present in original solution, based on actual yield= 1.77g moles
CaCl2 present in original solution, based on actual yield= 1.77g/molar mass of CaCl2=1.77g/110.98g/mol=0.016 moles
Total Volume of solution =V, which is 80ml

Answer:

2.21% wt/v

Explanation:

The mass/volume percentage, %wt/v, is an unit of concentration used in chemistry defined as 100 times the ratio of the mass of solute in g (In this case, CaCl2 = 1.77g) and the volume of solution in mL = 80mL

The %wt/v of this solution is:

%wt /v = 1.77g / 80mL * 100

%wt/v = 2.21% wt/v

Alex787 [66]

Answer:

About bonding

Explanation:

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bond.

Given a magnesium value of 4.5mg/dL, what is the result in SI units?
DaniilM [7]

Answer:

4.5x10^{-5}\frac{kg}{L}

Explanation:

Hello!

In this case, since the density in the international system of units is given in terms of kg for the mass and L for the volume, we need to perform a process of units conversions from mg and dL to kg and L as show below:

4.5\frac{mg}d{L}*\frac{1kg}{1x10^6mg}  *\frac{10dL}{1L} \\\\4.5x10^{-5}\frac{kg}{L}

Best regards!

Gerald's science teacher mixed room temperature samples of hydrochloric acid and sodium hydroxide in a large beaker. The solutio
shutvik [7]

Answer: Option (D) is the correct answer.

Explanation:

The chemical reaction equation will be as follows.

      HCl + NaOH \rightarrow NaCl + H_{2}O

This means a new substance has been formed and a chemical change has taken place.

A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.  

For example, A + B + Heat \rightarrow AB

On the other hand, a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.  

For example, C + D \rightarrow CD + Heat is an exothermic reaction.

Thus, we can conclude that in the given situation the beaker most likely felt warm because a chemical reaction was producing a new substance.
