# A car travels with a speed of 91.4 kilometers per hour (km/hr). Convert this speed to meters per second (m/s). Show your work.Round your final answer to three significant figures.Type your answer...

25.3889 m/s

Explanation:

We can simply write 91.4km/hr as,

91.4km

1 hr

=91400m

60 s × 60 s

=91400m

3600 s

= 25.3889 m/s

Which factor is likely to impact the possible number of compounds?

The correct answer is the tendency of all the elements to react with every other element.

Explanation:

A component in which two or more elements are bonded chemically leads to the production of a compound. A compound refers to a pure component as it comprises elements that are in their pure state. The formation of a compound takes place when the elements react with each other based upon their reactivity.

For example, the element chlorine is deficient of one electron and the element sodium exhibits one additional electron. Thus, chlorine easily reacts with the sodium in order to obtain stability. Therefore, the formation of sodium chloride takes place. Hence, it can be concluded that the tendency of all the elements to react with every other element is the condition, which is possible to influence the probable number of compounds.

the impact of possible number of compounds is the ability of all elements to react with every other atoms

When 282 gr of glycine are dissolved in 950 gr of a certain mystery liquid, the freezing point of the solution is 8.2 C less than the freezing point of pure. Calculate the mass of iron(III) chloride that must be dissolved in the same mass of to produce the same depression in freezing point. The van't Hoff factor for iron(III) chloride in X. Be sure your answer has a unit symbol, if necessary, and round your answer to significant digits.

Explanation:

Depression in freezing point is given by:

= Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte like glycine)

= freezing point constant = ?

m= molality

Weight of solvent = 950 g = 0.95 kg

Molar mass of glycine = 75.07 g/mol

Mass of glycine added = 282 g

Thus freezing point constant is

2)

= Depression in freezing point

i= vant hoff factor = 4 (for )

= freezing point constant =

m= molality

Weight of solvent = 950 g = 0.95 kg

Molar mass of = 162.2 g/mol

Thus mass of iron(III) chloride that must be dissolved in the same mass of to produce the same depression in freezing point is
