What is speed? If you walk 3 kilometers in 30 minutes, what is your average speed in kilometers per hour? Compare and contrast i
Mrrafil [7]

Answer:

See explanation

Explanation:

distance = 3 kilometres

time = 30 minutes or 0.5 hours

speed = distance/time = 3/0.5 = 6 Kmhr-1

Average speed is given by total distance covered divided by the total time taken while the instantaneous speed is the speed of an object at a particular instant or moment in time. Average speed refers to the whole journey while instantaneous speed refers to a particular point or instant in the journey.

distance= x

time = 3 hours

speed = 50 miles per hour

speed = distance/time

distance = speed * time

distance = 3 * 50

distance = 150 miles

How many moles are in 89 liters of water vapor?
Brut [27]

Answer:

4 moles

Explanation:

A mole is equal to 6.02214076 × 1023 of any chemical unit (atoms, molecules, ions)

To find number of moles in 89 litres of water vapor use the following formula:

1 mole = 22.4 L

That is 1 L = \frac{1}{24} mole

Volume of water vapor = 89 litres

Therefore,

Number of moles in 89 litres = \frac{89}{24}=3.7 ≈ 4 moles

Write the full symbol for the isotope of oxygen having 8 neutrons.​
Helen [10]

Answer:

Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O → 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ 18O Oxygen - 18 (aka 18O → 8 protons + 10 neutrons; a “heavy” oxygen).
