If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume
Liula [17]

Answer:

<h3>The answer is 200 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}\\

From the question

mass = 150 g

density = 0.75 g/cm³

We have

volume =  \frac{150}{0.75}  \\

We have the final answer as

<h3>200 cm³</h3>

Hope this helps you

An aluminum cation is smaller than the aluminum atom because it has fewer occupied energy levels. True false
butalik [34]

The molecules or atoms that are formed by gain or loss of one or more valence electrons are said to be ions.

When atom loss one or more valence electrons, results in formation of cation whereas when atom gain one or more valence electrons, then formation of anion occurs. Cations carry positive charge and anions carry negative charge.

In general, cations are smaller than the neutral atoms from which they are formed and anions are larger than the neutral atoms.

As cations are smaller than the related neutral atoms because the valence electrons are lost which are farthest away from the nucleus. After that, taking more electrons distant from the cation results in reduction of radius of the ion.

Thus, aluminium cation consist of few electrons which results in fewer occupied energy levels by the electrons further results in reduction of radius i.e. smaller size.

Hence, given statement is true i.e. aluminium atom is larger than the aluminium cation as cation has fewer occupied energy levels.

What cellular component is responsible for energy production and metabolic processes?
AlekseyPX

The cellular component responsible for energy production and metabolic processes is mitochondria.

What is Mitochondria?

A double-membrane-bound organelle known as a mitochondrion is found in the majority of eukaryotic organisms. The majority of the cell's adenosine triphosphate, which is then used as a source of chemical energy throughout the cell, is produced by mitochondria using aerobic respiration.

Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, mobility, and equilibrium, ATP is used as the main energy source in turn.
