What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
What is the first phase change that is most likely to occur as the pressure on nitrogen gas is increased and its temperature is decreased?
Condensation
What are some evidences that a chemical change occur?
Some physical signs are color change, bubbling, and rapid temperature reduction.
What causes matter to be in a solid liquid or gas state?
Generally the temperature of the material. Pressure can change the temperatures at which transformations occur.
What are the symptoms which show that the change is chemical?
1.Precipitation forms 2.Bubbles of gas appear 3.Colour changes occur 4.Temperature occurs 5.Change in volume occurs
What change of state occur when water changes to gas?
gas
Where in the respiratory system does gas change occur?
in the alveoli
When chlorine gas is separated from sodium chloride gas which change will occur physical or chemical?
It is a chemical change.2NaCl --> 2Na + Cl2
What happens when water evaporates to vapor?
A change of phase occur, from liquid to gas.
What must be transfered for any change of state to occur?
Energy must be transferred for any change of state to occur. A change of state is the same as a change of phase and there are four states that include liquid, solid, plasma, and gas.
What macronutrient does not occur as a gas?
Phosphorous does not occur as a gas
How does change occur from gas to liquid?
A change will occur if the gas evapourates. The moiture of the air will turn it into a liquid. If you boil a kettle and hold your hand just above the spout of it you will find that your hand becomes wet because the steam has hit your hand and turned into liquid. This is called condesation.

What gas helps decay to occur?
Any gas helps decay to occur.

What chemical compound forms when you heat Iodine?
Heating iodine sublimation occur: this is a direct change from solid to gas.
What are some evidences that a chemical change occur?
Some physical signs are color change, bubbling, and rapid temperature reduction.
