<u>Answer:</u> The balanced chemical equation is written below.

<u>Explanation:</u>

Double displacement reaction is defined as the chemical reaction in which exchange of ions takes place.

AB+CD\rightarrow CB+AD

The chemical equation for the reaction of potassium iodide and mercury (II) chloride follows:

2KI+HgCl_2\rightarrow HgI_2+2KCl

By Stoichiometry of the reaction:

2 moles of potassium iodide reacts with mercury (II) chloride to produce 1 mole of mercury (II) iodide and 2 moles of potassium chloride

Hence, the balanced chemical equation is written above.

A force of 25 newtons is exerted over an area of 50 square meters. Calculate
snow_lady [41]

Answer:

the pressure exerted in pascals is 0.5 Pa

Explanation:

The computation of the pressure exerted in pascals is shown below:

As we know that

Pressure = force ÷ area

= 25 ÷ 50

= 0.5 Pa

Hence, the pressure exerted in pascals is 0.5 Pa

We simply applied the above formula so that the correct pressure could come

Space shuttle tiles, sandstone, and the glass in quartz halogen lamps are all made out of the same stuff: silicon dioxide. Why d
tankabanditka [31]

Answer:

Explained

Explanation:

The bond angle between the Si-O-Si is 145° .But this can also vary between 100° and 170°,  It is because of which the changes in properties is happening. Bond angles can affect the hybridization, lone pair repulsion and electronegativity.

Thus , Space shuttle tiles, sandstone, and the glass in quartz have different properties and are used according to their property.

Which statement is true?
MissTica

Answer:

The correct answer is in an exothermic reaction the energy of the product is less than the energy of the reactants.

Explanation:

Exothermic reaction is a type of reaction that generates heat.As a result in case of an exothermic reaction the energy of the reactant is more than the energy of the product.

       That"s why the enthalpy change in an exothermic reaction is always positive .
