In Europe gasoline is often sold in liters. If a typical fill-up requires 11 gal of gas, how many liters are necessary?
egoroff_w [7]

Answer:

41,64 liters

Explanation:

In order to change the units we need to know the equivalence of said units.

1 gal of gas equals to 3,78541 liters.

We can use cross-multiplication in order to convert it into liters:

\frac{1 gal}{3.78541 L} = \frac{11 gal}{X}  \\\\X= \frac{3.78541 L x 11 gal}{1 gal}

A typical fill-up requires 41,64 liters.

One isotope of a metallic element has the mass number 67 and 37 neutrons in the nucleus. The cation derived from the isotope has
Nuetrik [128]
No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28

Zinc will have 30 protons and 28 electrons. So, it will have +2 charge

Symbol - Zn^+2

Place the following in order of increasing molar entropy at 298 K.
Genrish500 [490]

Answer:

SO < CO2 < C3H8

Explanation:

Entropy refers to the degree of disorderliness of a system. The standard molar entropy of a substance refers to the entropy of 1 mole of the substance vunder standard conditions.

The molar entropy depends on the number of microstates in the system which in turn depends on the number of atoms in the molecule.

C3H8 has 11 atoms and hence the highest number of microstates followed by CO2 having three atoms and least of all SO having only two atoms.
