What are the factors which determine a chemical change?
Change in colour, mass and state(ie liquid, gas or solid)
Give three things you might see if a chemical reaction takes place?
There are many observations that may occur when a chemical reaction takes place. Some of the things are:- Change of colour, change of temperature change of state. These can be observed by the features below There might be a change in colour when mixing the reactants; the vessel in which the reaction is taking place might get warm on the outside or cold depending on the type of reaction. There may be effervescence or fizzing with gas production; a precipitate may form.
How does change of state take place?
for a state change to happen it must lose or gain or loose kinetic energy
What observations does not indicate that a chemical change has occurred a. change of state b. formation of a precipitate c. absorption of energy d. release of a gas?
acually the answer depends on the nature of chemical reaction under consideration and depending on the reaction, there are two possible answers: a change of state and absorption of energy.
What change of state takes place when something sublimesfrom?
It is the phase change from a liquid to a gas.

What are the requirements for a liquor license at a guest house?
These regulations change from location-to-location and state-to-state. You must contact your state's liquor control agency to determine the requirements.
Determine how energy is related to change in state?
Energy is used to do work against in separating the mutually attracive atoms or molecules from each other to change them from solid into liquid and from liquid into gaseous state.
What type of change is a state of matter?
physical... the matter itself does not change. That would imply that a chemical change is taking place
Does your employer have to notify you if they change the day you get paid on?
Not that I am aware of - although you may check with your state Department of Labor to determine if there are any state laws regarding this.
How do you determine the statute of limitations if you have moved?
That depends on many circumstances. Typically the laws of the place the event took place are key. But, leaving the state often tolls that limit.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
How do you change a covenant in a homeowners association?
Review your governing documents to determine the process by which your covenants can be amended. There is no standard, and the guidelines vary by state.
