SPS2 Bonding
This is the chemical name for AlF3.
What is aluminum fluoride?
This level ranging from 0 to 14 can be tested with litmus paper.
What is pH?
This wave property gets bigger when a wave carries more energy.
What is amplitude?
An electromagnet's strength can be increased by increasing this.
What is the current, voltage, potential difference, number of coils, number of batteries, OR the size of the core?
In this state, the particles are vibrating in place.
What is a solid?
To write the formula for a binary ionic compound one crosses these down to make subscripts.
What are charges?
This solution contains hydroxide ions (OH-), tastes bitter, and has a pH of 8.
What is a base?
A tractor-trailer truck is driving down the road with its horn blowing.
This is the phenomenon that changes the frequency of the horn if the truck is moving toward or away from you.
What is the Doppler Effect?
As an ambulance drives toward a person, the person hears this kind of pitch.
What is increased or highere?
In colder temperatures, gas particles move at this pace.
slower or faster
What is slower?
This type of bond occurs between a metal that loses its valence electrons and a nonmetal that gains valence electrons.
What is ionic?
This type of solution is created when you add sugar to your Gatorade and shake it until no more will dissolve.
What is a saturated solution?
A gazelle is faster than a lion. In a race, this animal will reach the finish line first, having a lower time.
What is the gazelle?
This is when a wave passes through an opening and spreads out.
What is diffraction?
This law states that matter cannot be created or destroyed.
What is the law of conservation of matter or mass?
These all have this type of bond.
CO2
C6H12O6
H2O
What is covalent?
The rate of dissolution can be changed by adjusting the agitation, size of solute particles, and temperature. This, however, is the only way to change the solubility.
What is changing the temperature?
Two people use different simple machines (ramp and a pulley) to lift the same mass to the same height. Their work done is ( the same / different ) and their mechanical advantages are ( the same / different ).
What are "the same" and "different"?
This wave phenomenon happens when a wave enters a new medium, changes speed, and bends.
What is refraction?
When a reaction has equal numbers of all elements in the reactants and products.
What is balanced?
The names for P2O5 and N4O6.
What are diphosphorus pentoxide and tetranitrogen hexoxide?
You take a sugar cube and crush it into granulated sugar. This is what happened to the total surface area.
What is increased?
True or False:
This question can differentiate between mechanical and electromagnetic waves:
"Does the energy of the wave change with the frequency?"
What is true?
This is the order from slowest sound to fastest sound for these three situations:
1. We see a bolt of lightning and later we hear the thunderclap. ⚡
2. A person is listening with his ear against the rail for an oncoming train. 🚉
3. Navy ships use sonar (sound wave navigation and ranging) to detect submarines. 🚢⚓
What are 1,3, and 2?
gas slowest, liquid, solid is the fastest transmission of sound
Inside a pressure cooker, the temperature doubles. this happens to the pressure.
What is doubles?
