Answer:

A. The liquid propane in a gas grill burns in a flame.

Explanation:

Chemical changes is the change which occur when the substance combines with the another to form a completely new substance.

Considering Options B, C and D, the identity of each specie is not changed but the state is changed and thus, these are physical changes.

<u>On the other hand, Option A, when propane is being burnt in the flame , it changes to gas and its identity is lost. Thus, is a chemical change.</u>

List two non-metal elements that combine with three hydrogen atoms to satisfy the octet rule
viva [34]
  • Nitrogen as in NH₃.
  • Phosphorous as in PH₃.
<h3>Explanation</h3>

Hydrogen is in group 1. It is one electron away from the next noble gas element. It would form one single covalent bond when it bonds to nonmetals.

A nonmetal atom will gain three extra electrons when it bonds to three hydrogen atoms. For the molecule to be stable, that nonmetal atom should be three electrons away from the next noble gas element. Each of the atoms in question should contain 8 - 3 = 5 valence electrons when neutral. Which column on a periodic table contains such elements?

During the process of _____, gas loses heat and changes into a liquid.
Fantom [35]
<span>Condensation takes place when gas molecules lose heat and kinetic energy. The warmer molecules are the faster they move. Gas molecules move very quickly and have a lot of kinetic energy and heat energy. As the gas molecules lose heat they also lose kinetic energy. As the molecules slow down they move closer together to form liquids.</span>

Select the correct answer from each drop-down menu. carbon is found in all living organisms. the constant flow of carbon on eart
Nady [450]

The continuous cycling of carbon in the earyh is known as the carbon cycle.

<h3>What is the carbon cycle?</h3>

The carbon cycle is a cycle which explains the various processes by which carbon is recycled between the atmosphere and the earth.

The constant flow of carbon on earth through organisms and the air is known as the carbon cycle. Plants absorb carbon from the atmosphere in the form of carbon dioxide. They use it for respiration and food production.

Animals consume plants, transferring carbon along the food chain.

Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.

Carbon enters back into the atmosphere in the form of carbondio dioxide.

Therefore, the continuous cycling of carbon in the earth is known as the carbon cycle.
