Answer:

Particles of objects have both kinetic and potential energy. Because particles are constantly in motion, they have kinetic energy. These particles are arranged in specific ways in different objects. Therefore, they also have potential energy.

How many grams of nano3 remain in solution at 20 ∘c?

Amanda [17]

<span>the table say that at 20 degree celcius 88.0g of NANO3 will remain dissolved in 100 gm of H2O so at 20 degree celcius 80.0g of H20 will dissolve (88.0g)x(80g/100g)=70.4g of NANO3 so at 20 degree celcius 86.3g-70.4g= 15.9 gram of NANO3 will come out of solution.</span>

Select the properly written and balanced equation for the following chemical reaction: Sodium metal and an aqueous solution of m

Setler [38]

Answer: $2Na(s)+MgI_2 (aq)\rightarrow 2NaI(aq)+Mg(s)$

Explanation: The chemical reaction is written by writing down the chemical formulas of the reactants on the left hand side and the chemical formulas of products on the right hand side separated by a right arrow.

This is a single displacement reaction in which a more reactive element displaces the less reactive element from its salt solution. Thus sodium is more reactive than Mg and thus displaces it from $MgI_2$ .

$2Na(s)+MgI_2 (aq)\rightarrow 2NaI(aq)+Mg(s)$

The number of atoms of each element must be same on both sides of the reaction so as to follow the law of conservation of mass. Thus the equation is balanced.
