The relative mass of an electron is 1/1840 the mass of a C-12 atom. Hence, option B is correct.

<h3>What is an electron?</h3>

An electron is a negatively charged subatomic particle.

An electron is very small, about 1/1,837th the mass of a proton. Atomic Weights Atomic mass of an atom is expressed in atomic mass units (amu) which are approximately 1.66 X 10^{-24} grams. A more conventional way of expressing the mass of an atom is Atomic Weight.

Atomic mass units are expressed relative to the atomic mass unit of an unbound neutral carbon-12 atom.

Hence, the relative mass of an electron is 1/1840 the mass of a C-12 atom.

Lab 2: paper chromatography of organic dyes<br> Picture of questions below.
Anika [276]

Answer:

The three primary colors used when mixing dyes or paints are red, yellow, and blue. Other colors are often a mixture of these three colors. Try running a chromatography test again with non-primary-color markers, like purple, brown, and orange.

Explanation:

<h3><em>Mixtures that are suitable for separation by chromatography include inks, dyes and colouring agents in food. ... As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out.</em></h3>

What happens to the glucose molecule during the process of cellular respiration? (5 points)
Dmitry [639]

The correct answer is option a, that is, it gets broken down.  

A set of metabolic reactions and procedures, which occurs in the cells of organisms to transform biochemical energy from nutrients into ATP, and then discharge waste components is known as cellular respiration. At the time of cellular respiration, a molecule of glucose gets dissociated slowly into water and carbon dioxide. With it, some of the ATP is generated directly in the reactions, which transform glucose.

Which type of change must occur to form a compound? (1) chemical (3) nuclear(2) physical (4) phase?
Leya [2.2K]
Let's go through each of the answers and think about why they work or don't work. 

Chemical forms compounds. 

Nuclear changes the element completely. We're going to use the sun as an example. The sun is in a state of plasma. It's really hot and has all these particles hitting into each other. The nucleus' of atoms are hitting into each other forming larger elements. It's real crazy. Nuclear is not correct. 

Physical cannot form a compound.
