A car covers a distance of 22.75 km in 17.04 minutes. Use dimensional analysis to calculate its speed in meters/second. Do not e

kati45 [8]

The speed of the car = 22.25 m/s

<h3>Further explanation</h3>

Given

A distance of 22.75 km

Time = 17.04 minutes

Required

The speed (in m/s)

Solution

Speed is the ratio of distance per time

Can be formulated :

v = d/t

v= speed, m/s

d=distance=m

t=time,s

Input the value :

$\tt v=\dfrac{22.75~km}{17.04~minutes}\times \dfrac{1000~m}{1~km}\times \dfrac{1~minute}{60~second}\\\\v=\boxed{\bold{22.25~m/s}}$

Initial Activity- What mass of solute will dissolve in 100g of water at the following temperatures?

pantera1 [17]

The mass of solute will dissolve in 100g of water at the following temperatures will be 153 gms, 40 gms, 70gms simultaneously.

<h3>How dissolution of solute is affected by temperature ?</h3>

On increasing temperature the amount of solute for dissolution decreases.

It is independent of the nature of solute.

Hence,

KNO₃ at 70degree = 153 gms
NaCl at 100 degree = 40 gms
NH₄Cl at 90 degree = 70gms

Answer: $3Ag^+(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)$

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolytes and are represented in the form of ions.

The complete ionic equation will be:

$3Ag^+(aq)+3NO_3^-(aq)+Fe^{3+}(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)+Fe^{3+}(aq)+3NO_3^-(aq)$

Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

In this equation, $Fe^{3+}$ and $NO_3^-$ are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be:

$3Ag^+(aq)+3Cl^-(aq)\rightarrow 3AgCl(s)$
