where
A₀ and A_t are the amounts at t = 0 and t
k is the rate constant
2. Calculate the half-life
The soup water would turn into soap.
Answer:
C) As a gas is heated, the pressure decreases.
Explanation:
From the choices given, the statement that "as a gas is heated, the pressure decreases is false".
When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.
- Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
- When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
- Thus, they take up even more space allowing volume to increase appreciably.
Answer: All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.

Air can be separated into its components by means of distillation in special units. So-called air fractionating plants employ a thermal process known as cryogenic rectification to separate the individual components from one another in order to produce high-purity nitrogen, oxygen and argon in liquid and gaseous form.
