<span>There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution.  MOlality is expressed as moles per kg solution. 

5.25 mol H2SO4 / kg solution ( 1 kg / 1000 g ) ( 1.266 g / mL ) ( 1000 mL / 1L ) = 6.6 M H2SO4</span>

A trucker is driving from New Jersey to California to make a delivery of couches. He forgets to adjust the pressure of his tires
aniked [119]

Answer:

<u>Gay-Lussac's law.</u>

Explanation:

According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is <em>directly</em> proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.

Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.

Which substance is an Arrhenius base?<br> (1) CH3OH (3) LiOH<br> (2) CH3Cl (4) LiCl
Nana76 [90]
According to Arrhenius Theory of acids and bases, an Arrhenius base produces OH-.

Among the four options, (3) LiOH is the correct one because it can separate into Li+ and OH- when being put in water.

Hope this helps~

Assuming that the bath contains 250.0 g of water and that the calorimeter itself absorbs a negligible amount of heat, calculate
Anvisha [2.4K]

Answer:

-3272     kJ/mol

Explanation:

Given and known facts

Mass of Benzene = 0.187 grams

Mass of water = 250 grams

Standard heat capacity of water = 4.18 J/g∙°C

Change in temperature ΔT = 7.48°C

Heat

=250 * 4.18 * 7.48\\=7816.6 \\=7.82

Heat released by benzine is - 7.82 kJ

Now, we know that

0.187 grams of benzene release = -7.82  kJ heat

So, 1 g benzine releases

\frac{ -7.82 }{0.187}\\= -41.8

kJ/g

0.187 * \frac{1}{78.108}=0.00239 mol C6H6

Heat released

= \frac{-7.82}{ 0.00239}

=-3272     kJ/mol
