<span>Given the same conditions of temperature and pressure the noble gas He will diffuse most rapidly. </span>He is the smallest noble gas and so it can diffuse (pass through) membranes the easiest.It is colorless, odorless, tasteless, non-toxic chemical element.
Correct answer:A
Answer:
1. some thing that has matter is an apple, a person,a table. things that does 2.not Light.,Sound.,Heat.Energy.Gravity.Time.A Rainbow.Love.
3. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
4.A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products!
5.Precipitate: In chemistry, a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid. In meteorology a precipitate is liquid or solid water (rain, snow, etc.) falling from the sky.
6.n simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.
hope this help plz give me a thxs and brainlyest and a five star thx and you welcome let me know if this helped
Explanation:
Answer:
There can be a number of chemical processes by which a compounds can be broken down into simpler substances. The most common and wide-spread of such processes is Catabolism. Along with anabolism, catabolism make up the metabolism process for living organisms.
Answer:
<h2>The answer is 28.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of table = 12 cm³
density = 2.35 g/cm³
The mass of the table is
mass = 2.35 × 12
We have the final answer as
<h3>28.2 g</h3>
Hope this helps you
