the cost of gas is given as:

$0.95/gallon

the average of car is

20miles / gallon

The distance of trip is 420 miles

Thus the gas consumed for the trip is

Gas consumed = miles covered / car average

gas consumed = 420 / 20 = 21 gallon

The cost of gas will be = total gas consumed X price of each gallon

the cost of gas = 21 X $0.95 =$19.95

Answer : The cost of gasoline for a 420-mile trip is, $19.95

Solution :

As, 20 mile distance covered by 1 gallon of gas

So, 420 mile distance covered by $\frac{420}{20}=21gallon$ of gas

Now we have to calculate the cost of gasoline.

As, 1 gallon of gas cost = $0.95

So, 21 gallon of gas cost = $\$0.95\times 21=\$19.95$

Therefore, the cost of gasoline for a 420-mile trip is, $19.95

What type of reaction is BaCl2 + Na2SO4 → 2NaCl + BaSO4?

maria [59]

Answer:

Double Displacement reaction

Explanation:

BaCl2 + Na2SO4 → 2NaCl + BaSO4

Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.

What is used to determine the number of each atom in an ionic formula

ladessa [460]

Answer:

The charge carried by each ion (oxidation state of each atom)

Explanation:

If we have an ionic compound and we want to write its formula, we must first know the magnitude of charge on each ion (shown as oxidation state of the atoms involved) because the magnitude of charge on each ion is eventually crisscrossed and gives the subscript (number of atoms) for each atom in the formula.

For instance, let us write the formula of calcium bromide. Ca has a charge of +2 while Br has a charge of -1. If we exchange the charges and ignore the signs such that the crisscrossed charges form subscripts we can now write; $CaBr_{2}$ .
