1. How many liters are there in one cubic meter?

1 liter

100 liters

1000 liters

10 liters

2. If the equilibrium constant (K_eq) for a reaction is significantly greater than 1,
what can be inferred about the concentrations of products and reactants at
equilibrium?

The concentrations of products and reactants are equal.

The reaction has not reached equilibrium.

The concentration of reactants is much greater than that of products.

The concentration of products is much greater than that of
reactants.

3. Which is the correct equation for converting a Celsius temperature to the
Fahrenheit scale?

ºF = 1.8ºC − 32

ºF = 1.8ºC + 32

ºF = 32ºC − 1.8

ºF = 32ºC + 1.8

4. What is the equivalent of one kilogram in grams?

, 1000 grams

1 gram

10 grams

100 grams

5. Celsius to Fahrenheit is calculated by?

(5/9 + 32) + °C

(5/9 * °C) + 32

(9/5 * °C) + 32

6. One liter is equal to:

1,000 mililiters

1,000 miligrams

1,000 micrograms

1,000 milimeters

7. If the Celsius temperature is known, then the Kelvin temperature can be
found using the equation:

K= C/273.15

K= C-273.15

K= C+273.15

K= C x 273.15

8. What is the formula used to convert a temperature from Celsius to
Fahrenheit?
