Chemistry A
This is a type of change. When two solutions are mixed together, they become fizzy and change colour.
What is Chemical Change?
This type of particle is positively charged.
This is the unit for current.
What is Ampere?
This type of material allows electrons to flow easily.
What is a Conductor?
This type of celestial objects and planets both orbit around the Sun.
What is Asteroid?
Hydrogen gas is an example of this type of chemical matter.
What is an element?
What is Viscosity?
You can charge a metal-leaf electroscope in this way without contact.
This happens if you connect both ends of an energy source without a load.
What is Short Circuit?
An example of this type of planet supports a ring system and is made of gas.
What is an Outer Planet?
A phosphorus atom has this number of valence electrons.
What is 5?
This type of bond holds Na+ and Cl- together.
What is Ionic Bond?
When charging the electroscope by having it in contact with a negatively charged balloon, this is the resultant net charge of the electroscope.
What is Negative?
When you perform the Ohm's Law experiment and plot the data with voltage on y-axis and current on x-axis, this is the supposed shape of the line of best fit.
What is Linear?
This is home to planet Earth and countless stars and other planets. A black hole is believed to exist at its centre.
What is the Milky Way Galaxy?
This is the name of this chemical: CCl4
What is Carbon Tetrachloride?
An element from this group likes to form ions with -1 charge.
What is Group 17?
When a 2.0-Ohm resistor and a 4.0-Ohm resistor are connected in parallel, in a circuit powered by a 3.0-V battery, this is the current passing through the 2.0-Ohm resistor.
This measures the rate of flow of charges through a conductor.
What is Current?
There are approximately 63000 astronomical units (AU) in 1 light year (ly). This many AUs is equivalent to 2.5 ly.
What is 157500?
This is the chemical name for PbO2.
What is Lead(IV) Oxide?
This is the chemical formula when X2+ and Y3- are combined chemically.
X3Y2
All light bulbs are 1 Ohm. What is the equivalent resistance when two light bulbs are in series, connected in parallel with another set of three light bulbs in series?
What is 1.2 Ohms?
The efficiency of a light bulb is 60%. The light bulb is powered by a 3.0-V battery and 200-mA current passing through. This amount of light energy is given off by the light bulb every minute.
What is 21.6 J?
This type of celestial object consists of ice and dust.
What is a Comet?
