What changes the rate of a chemical reaction or allows a chemical reaction to occur?
Heat?
In a beaker sugar is dissolved in water and then the water is heated and evaporates The sugar is recovered and heat is again applied Vapor is released and the material in the beaker changes from?
In a beaker, sugar is dissolved in water, and then the water is heated and evaporates. The sugar is recovered, and heat is again applied. Vapor is released, and the material in the beaker changes from white to black. What must you know to determine if a chemical change occurred? CO2 (carbon dioxide) CuO (oxidized copper) H2O (distilled water) H2O2 (hydrogen peroxide) NaCl (sodium chloride)
How can people tell the chemical reaction in a beaker?
Mostly by means of colour change and heat dissipated from the beaker...
Does a high specific heat allow water to heat slowly cool slowly or both?
the right answer is heat slowely
What will cause heat to flow slowly?
Interatomic separation causes heat to flow slowly. As there will be time involved in transferring heat at a gap.
How do you heat a beaker of water?
With a heat source, slowly so as to not shatter the beaker.
What changes occur if you burn a piece of charcoal?
the heat will generate
What are temperature changes that occur even though heat is not added or subtracted?
Temperature changes that occur without any heat addition or subtraction is defined as internal energy. Another term for this occurrence is adiabatic change.

What is used to heat a beaker?
a heater
How do you create a solution?
Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
How do you heat a liquid to 90 degrees?
if your in a lab, put water in a beaker, place the beaker on a tripod and heat with Bunsen burner, (use thermometer to measure
Describe the process of condensation When does condensation occur?
It occurs when a gas changes into a liquid. Heat is given off.
What are some changes that occur when a sedimentary rock changes into a metamorphic rock?
To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.

Can you heat a beaker over a Bunsen burner?
If you want to
