How does changing the ratio of nitrogen atoms and oxygen atoms change the compounds?
Changing the ratio of nitrogen and oxygen atoms can result in different compounds being formed. For example, nitrogen dioxide (NO2) and nitric oxide (NO) are both nitrogen-oxygen compounds with different ratios of N to O atoms. Changing this ratio can affect the properties of the compounds, such as their reactivity and toxicity.
Is iron rust physical change or chemical change?
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.
A change that produces matter with a different composition than the original matter is what?
This is a chemical change.
What is the most important quiestion to ask to determine whether a change is physical or chemical?
The most important question to ask is whether the change results in a new substance being formed. Physical changes involve a change in appearance, state, or size of a substance without forming a new substance. Chemical changes involve a reaction that results in the formation of new substances with different chemical properties.
What process uses electricity to seperate organic compounds?
Electrolysis is a process that uses electricity to separate organic compounds by passing an electric current through a solution containing the compounds. This results in the compounds being broken down into their individual components based on their electrochemical properties.
What type if change results in a new substance being formed?
chemical
Is rotting a physical or chemical change?
Rotting is a chemical change. It involves the decomposition of organic matter through biochemical processes, where complex substances break down into simpler compounds, often facilitated by microorganisms. This transformation results in new substances being formed, which distinguishes it from a physical change that does not alter the chemical composition of the material.
Can a compound be formed by chemical processes such as combusion?
Definitely, yes. In fact all compounds may be thought of as having been formed by chemical processes, one these processes being combustion. And combustion almost always results in the formation of chemical compounds. For example, if you burn the metal magnesium in oxygen the compound magnesium oxide is formed.
What is a chemical that increases the rate of reaction with out being part of the compounds being formed?
This substance is called catalyst.
Is bleaching tiles a physical or chemical change?
Bleaching tiles is primarily a chemical change. This process involves the application of bleach, which reacts with stains and discoloration on the tiles, breaking down the compounds causing the discoloration. Unlike a physical change, which only alters the appearance without changing the chemical composition, bleaching results in new substances being formed as the original stains are chemically altered.
What is the differences and similarities of a compound and a mixture?
Both are formed from atoms. A compound cannot be divided in atoms by physical procedures.The mixture being formed from compounds can be divided in compounds by physical procedures.

What kind of change occurs with a new substance being formed?
Chemical change.
What happens when you boil gold in a lye?
When you boil gold in lye, it can react with the lye to form various gold compounds. The presence of lye can change the physical and chemical properties of gold, potentially leading to different colors or compounds being formed depending on the specific conditions of the reaction.
