lilavasa [31]

<h3>Answer:</h3>

= 633,600 Inches

<h3>Explanation:</h3>

Speed refers to the rate of change in distance traveled by a body in motion.

It is the ratio of distance to time taken.

It is calculated by;

Speed = Distance ÷time taken

Therefore;

Distance = Speed × time

In this case;

Time taken = 12 minutes ( but 1 hr = 60 mins)

Thus, t = 0.2 hours

Speed = 50.0 miles/hour

Thus;

Distance = 50.0 miles/hr × 0.2 hours

= 10 miles

But, we are require to give the distance in inches;

1 mile = 63360 Inches

Therefore;

10 miles = 10 × 63360 Inches

= 633,600 Inches

The equation for density, d, is

ss7ja [257]

Answer: The density of substance is $3.38g/cm^3$

Explanation:

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of substance = 61.6 g

Volume of substance = $18.2cm^3$

Putting values in above equation, we get:

$\text{Density of substance}=\frac{61.6g}{18.2cm^3}\\\\\text{Density of substance}=3.38g/cm^3$

Hence, the density of substance is $3.38g/cm^3$

Predict the following product(s) of the following reaction? F2 + KCI →

slega [8]

Answer:

${ \rm{F _{2(g)} + 2KCl _{(aq)} → { \bold{2KF _{(g)} + Cl_{2(g)} }}}}$

Explanation:

» The prediction is 98% correct because single displacement reaction type is highly possible.

This is because Fluorine has is more electronegative than Chlorine in Potassium Chloride. So, it strongly displaces Chlorine from the solution hence forming Chlorine gas.

» The 2% of wrong prediction maybe because of wrong reactant measurements following mole concept chemistry.

If you are asked the observation,

Observation » A green yellowish gas is formed.

This gas is Chlorine gas (Cl2)
