A block is pulled 0.90 m to the right in 2.5 s.
Blizzard [7]

The block’s average speed : 0.36 m/s

<h3>Further explanation</h3>

Distance is the length traveled by an object within a certain of time .  

Average speed = total distance/total amount of time ,

Can be formulated :

\tt avg.s(speed)=\dfrac{\Delta D}{\Delta t}

ΔD= total distance

Δt= total time

A block is pulled 0.90 m to the right in 2.5 s :

ΔD= total distance = 0.9 m

Δt= total time = 2.5 s

The block’s average speed :

\tt avg.s=\dfrac{0.9}{2.5}=0.36~m/s

When solutions of silver nitrate and sodium chloride are mixed, silver chloride precipitates out of the solution according to th
kipiarov [429]

The concentration of the sodium chloride would be 0.082 M

<h3>Stoichiometric calculations</h3>

From the equation of the reaction, the ratio of AgCl produced to NaCl required is 1:1.

Mole of 46.6 g AgCl produced = 46.6/143.32 = 0.325 moles

Equivalent mole of NaCl = 0.325 moles.

Molarity of 0.325 moles, 3.95 L NaCl = mole/volume = 0.325/3.95 = 0.082 M
