What mass of kcl in grams must be added to 500 ml of a 0. 15 m kcl solution to produce a 0. 40 m solution.
iren [92.7K]

91.4 grams

91.4 grams of kcl in grams must be added to 500 ml of a 0. 15 m kcl solution to produce a 0. 40 m solution.

C = mol/volume

2.45M=mol/0.5L

2.45M⋅0.5L = mol

mol = 1.225

Convert no. of moles to grams using the atomic mass of K + Cl

1.225mol * \frac{39.1+35.5}{mol}

mol=1.225

=1.225 mol . \frac{74.6g}{mol}

=1.225 . 74.6

=91.4g

therefore, 91.4 grams of kcl in grams must be added to 500 ml of a 0. 15 m kcl solution to produce a 0. 40 m solution.

Methane is a gas at room temperature and pressure. Explain why this is the case.
Sveta_85 [38]

Answer:

hope it helps ❤

Explanation:

Methane only has london dispersion forces since it is nonpolar. London dispersion force is the weakest intermolecular force, so the forces between its molecules will be weak. This leads to a low boiling point that is lower than room temperature, which makes it a gas at room temperature.

Metals bond with halogens to form colorless metal halides. During an experiment, bromine water was added to a solution of potass
Anvisha [2.4K]

Answer:

Bromine displaced iodide to form iodine

Explanation:

In this experiment, liquid bromine was allowed to react with a solution of potassium iodide.

Initially, we had a colorless KI solution which was mixed with light orange Br_2. If we add a light orange solution to a colorless solution, liquid bromine will get diluted and we'll see a slight decrease in its color intensity, however, if no reaction takes place, no color change will occur.

In the experiment, however, we examine a formation of a deep brown solution. Remember that iodine solution would form a brown solution.

As a result, bromine displaced iodide anion from potassium iodide:

2~KI~(aq) + Br_2~ (l)\rightarrow 2~KBr~(aq) + I_2~(aq)
