Answer:
energy that is transmitted in the form of electromagnetic waves.
Explanation:
Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
Answer:
The volume of the gas decreases also in a 21% based on the Avogadro's law
Explanation:
Based on Avogadro's law, the volume of a gas is directely proportional to the amount of moles of gas when temperature and pressure remain constants.
The formula is:
V1 / n1 = V2 / n2
<em>Where V is volume and n are moles in 1, initial state and 2, final state of the gas.</em>
<em />
At beginning, V1 = 100%, n1 = 100%,
As the chemist removes 21% of the gas, 79% of moles remain = n2.
Replacing:
100% / 100% = V2 / 79%
V2 = 79%, that means:
<h3>The volume of the gas decreases also in a 21% based on the Avogadro's law</h3>
No. Changing of color is a physical change.
<h3><u>Answer;</u></h3>
Cellulose
<h3><u>Explanation</u>;</h3>
- Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
- <em><u>It is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
- <em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very strong.</u></em>
- The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.
Answer:
i) ciclobutano
ii) 3-etil-4-metil ciclopenteno
Explanation:
Toda la idea de la nomenclatura IUPAC es permitir que la estructura de la sustancia se derive de su nombre y viceversa.
La nomenclatura IUPAC es un sistema universalmente aceptado para nombrar compuestos químicos.
los nombres de los compuestos enumerados son;
i) ciclobutano
ii) 3-etil-4-metil ciclopenteno
