Answer:

The reactants and products determine the type of chemical reaction. If there are more products than reactants, then it is a decomposition reaction. If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.

Answer:

The information of properties of the reactants and substrate that produces provide information about the type of reaction and also helps in classify the chemical reaction.

If there are fewer reactants than the products the reaction is classified as a decomposition reaction. If oxygen is present in the reaction as a reactant it is a combustion reaction. A synthesis reaction occurs if the reactants are more than the products. A single replacement reaction occurs when one ion replaces another.

Other than these reactions there are some other reactions that can be classified with knowing reactants and products.

What is an indicator? What does it tell you about solutions?

Sophie [7]

Answer:

Explanation:

The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.

An example of a solid solution is copper true or false

garik1379 [7]

This is false, because copper is an element.
To be solution, it has to have at least 2 different substances. Solid solution of metals is often called alloy.

In an experiment, a student dissolves 56.3g of MgCl2 in 0.12kg of solvent. What is the molality of this solution? Show your work

Kazeer [188]

<u>Answer:</u> The molality of magnesium chloride is 4.93 m

<u>Explanation:</u>

To calculate the molality of solution, we use the equation:

$Molality=\frac{m_{solute}}{M_{solute}\times W_{solvent}\text{ in kg}}$

Where,

$m_{solute}$ = Given mass of solute $(MgCl_2)$ = 56.3 g

$M_{solute}$ = Molar mass of solute $(MgCl_2)$ = 95.2 g/mol

$W_{solvent}$ = Mass of solvent = 0.12 kg

Putting values in above equation, we get:

$\text{Molality of }MgCl_2=\frac{56.3}{95.2\times 0.12}\\\\\text{Molality of }MgCl_2=4.93m$

Hence, the molality of magnesium chloride is 4.93 m
