How does the difference in the mass of the ball affects the changes in the distance of the object
beks73 [17]

Answer:

In very simple words ,

As the weight increases the gravitational force acting on the ball increases and thus it effects the change in the distance of the ball as the ball will fall very close to its initial distance if it has more mass and shall go far if the mass is less .

Sodium permanganate and iron(III) chloride are both dissolved in a beaker of water. In a double displacement reaction, two new p
Nastasia [14]

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

<u>Explanation:</u>

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

AB+CD\rightarrow CB+AD

When sodium permanganate reacts with iron (III) chloride, it leads to the production of sodium chloride and iron (III) permanganate.

The chemical equation for the reaction of sodium permanganate and iron (III) chloride follows:

3NaMnO_4(aq.)+FeCl_3(aq.)\rightarrow Fe(MnO_4)_3(s)+3NaCl(aq.)

By Stoichiometry of the reaction:

3 moles of aqueous solution of sodium permanganate reacts with 1 mole of aqueous solution of iron (III) chloride to produce 1 mole of solid iron permanganate and 3 moles of aqueous solution of sodium chloride

Hence, the balanced chemical equation is written above.

A student dissolves 0.0688 mol of sodium hydroxide in water to make a 0.250 L solution. What is the molarity of the solution?
den301095 [7]
Number of moles = 0.0688 moles of NaoH

volume = 0.250 L

Molarity = moles of solute / volume ( L )

M = 0.0688 / 0.250

M = 0.28 M
