2 answers:

8 0

To name an ionic compound, you simply need to find the names of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.

Explanation:

Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion.

A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on

vlada-n [284]

Answer:

281s

Explanation:

Given parameters:

Speed of the scooter = 1.45min per mile

Fuel economy of engine = 85miles per gallon

Quantity of fuel = 145mL

Unknown:

Time of travel with the volume of fuel given = ?

Solution:

To solve this problem, we need to find the distance the fuel will last.

Rate of fuel consumption by the engine = 85miles per gallon

Convert 145mL to gallons;

3785.41mL = 1 gallon

145mL will therefore give $\frac{145}{3785.41}$ = 0.038gallons

So;

Distance covered = 85miles per gallon x 0.038gallons = 3.23miles

From;

Rate of travel = $\frac{time }{distance}$

Time = rate of travel x distance = 1.45 minutes per mile x 3.23miles

Time = 4.7min

1 min = 60s

4.7min = 4.7 x 60 = 281s

According to the big bang theory, which statements are accurate about how the universe came to be? Check all that apply.

asambeis [7]

The term Big Bang defines that the Universe has expanded from the ancient hot and thick primary situation at some fixed time in the past.

Big Bang theory refers to the origin of the Universe. In the beginning, universe is very heavy and small hot ball of matter. It was a point no bigger than the head of a pin when all the things squished with each other and universe is expanded with huge explosion of energy. Due to expansion, it is cooled and results in the formation of Stars and galaxies. After sometime, atoms formed like helium and hydrogen.

Thus, statement (1), (3) and (4) is correct whereas statement (2) and (5) is incorrect.
