What is a Latin word that means 'coal'?
It depends upon the situation. For there are two known equivalents in ancient, classical Latin for the English word 'coal'. A piece of coal is a piece of glowing carbon, or of charred wood. The Latin word pruna refers to the live coal, and the word carbo to burning or burned wood.
What two chemicals react to form a new substance?
An example of two chemicals that react to form a new substance is hydrogen and oxygen combining to form water. This chemical reaction is a synthesis reaction where the two reactants combine to create a new compound with different properties.
A solid product that may form when chemicals in two liquids react?
A precipitate is a solid product that may form when chemicals in two liquids react. It is insoluble and falls out of solution as a result of the chemical reaction.
What are the chemicals called when they are mixed?
a solution is two substance mixed together
What are the two chemicals that form after coal and oil are burned?
Water and Carbon dioxide?
Which fossil fuel could supply energy needs for about two hundred years but is linked to acid rain?
Coal is a fossil fuel that could supply energy needs for about two hundred years but is linked to acid rain. When coal is burned, it releases sulfur dioxide and nitrogen oxides, which can react with water vapor in the atmosphere to form acids that fall back to Earth as acid rain.
What is a chemical change in your own words?
A chemical change is a process by which one or more chemicals become different chemicals. So, burning is a classic example of this. Methane, when burned, combines with oxygen to form water and carbon dioxide. Two chemicals become two other chemicals. In comparison, in a physical change the chemical identity remains the same even though physical attributes change. If I saw a piece of wood in half, the wood has changed, but it is still wood. I just have two pieces instead of one.
When two or more atoms bond and share electrons what do they form a compound?
A new form of chemicals

What a two or more substances that are combined chemically?
Two or more substances which can chemically react form new chemicals after the reaction.1. If these chemicals react they form new compounds.2. Without a chemical reaction they form a mixture.Read more: What_is_two_or_more_substance_are_combined

What two chemicals form the outer parts of the model DNA?
The two chemicals that form the outer parts of the DNA molecule are deoxyribose sugar and phosphate groups. These molecules form the backbone of the DNA double helix structure, with the nitrogenous bases positioned in between them.
What is the greenhouse effect and two chemicals that can cause it?
The Greenhouse effect is when all of the carbon is burned off and rises up, the atmosphere traps the heat in, which is one reason for global warming
What are the chemicals called when they are mixed?
a solution is two substance mixed together
