A change in the state of matter is caused if enough _____ is added to or removed from an object.​

Every unicellular organism prospers by executing metabolic activities.

Metabolic activities encompass the set of chemical reactions essential for sustaining life.

Explanation:

Different metabolic pathways maintain an organism's viability. Various metabolic activities occur in all living organisms.

These include processes like cellular respiration, reproduction, excretion, and digestion. Each living cell engages in these activities to survive.

Organisms acquire the energy necessary for these activities through food consumption.

Answer:

Ir(NO2)3

Explanation:

The molar mass is 330.2335, in case that's also required.

Result: 1.68 L of liquid nitrogen is generated during the gas liquefaction process.

Clarification:

This process involves transforming gaseous nitrogen into its liquid form.

The two states possess distinct densities, thus occupying varying volumes; however, the mass remains constant.

Step 1: Calculate the mass of nitrogen gas

Let’s determine the mass of nitrogen gas associated with 297 L.

The density formula is:

With a density of nitrogen gas at 4.566 g/L and a volume of 297 L, we can compute the mass of nitrogen gas as follows:

Using these values yields:

The mass of nitrogen gas calculates to be 1356 g.

Step 2: Derive the volume of liquid nitrogen from the mass obtained

The mass for liquid nitrogen remains the same.

With the density of liquid nitrogen at 809 g/L, we can substitute this into our formula to find the volume of liquid.

Therefore, the volume of liquid nitrogen is 1.68 L.

Answer: The Answer is A.

Explanation:

The energy of a photon is directly related to its electromagnetic frequency, meaning it is inversely related to the wavelength. A higher frequency results in greater energy for the photon. Conversely, a longer wavelength corresponds to lower energy levels.

A secondary alkyl halide would be characterized by having a carbon atom connected to two other carbon atoms, with bromine attached to that carbon.

Therefore, bromo-hexane qualifies as a 2-degree or secondary alkyl halide
