A teacher asks students to make a model of a transform plate boundary. The
students use blocks to represent tectonic plates and slide the blocks past each
other in the directions of the arrows as shown.
Transform Plate Boundary
Plate
Plate
Which event can the student best demonstrate with their model?
Answer:
C Earthquake
Explanation:
I just took this test and it’s on Quizizz
The event which best describes the model is an Earthquake. Earthquake is
formed when two plate boundaries collide with each other.
The plate boundaries colliding results in them being stuck. Pressure then
builds up between them which results in the plates breaking loose as time
goes on.
The movement that results from the plates breaking loose is what results in
an earthquake being experienced.

I need chemical properties of matter that can be classified.
Answer:
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

Answer:
20 g of copper (II) oxide, CuO
Explanation:
The balanced equation for the reaction is given below:
CuO + 2HCl —> CuCl₂ + H₂O
From the balanced equation above,
1 mole of CuO reacted to produce 1 mole of CuCl₂.
Next, we shall determine the number of mole of CuO needed to produce 0.25 mole of CuCl₂. This can be obtained as follow:
From the balanced equation above,
1 mole of CuO reacted to produce 1 mole of CuCl₂.
Therefore, 0.25 mole of CuO will also react to produce 0.25 mole of CuCl₂.
Finally, we shall determine the mass of 0.25 mole of CuO. This can be obtained as follow:
Mole of CuO = 0.25 mole
Molar mass of CuO = 64 + 16
= 80 g/mol
Mass of CuO =?
Mole = mass /Molar mass
0.25 = mass of CuO /80
Cross multiply
Mass of CuO = 0.25 × 80
Mass of CuO = 20 g
Therefore, 20 g of copper (II) oxide, CuO is needed for the reaction.
True or False: Potential and kinetic energy are fixed and do not convert between the two types. *
10 points
Answer:
false
Explanation:
According to the law of conservation of energy, energy can neither be created nor destroyed but can be converted from one form to another. Hence, the given statement is true.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of energy is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

How many moles are 5.55x10^25 atoms of Mg
Answer:
[tex]\boxed {\boxed {\sf About \ 92.2 \ moles \ of \ Magnesium}}[/tex]
Explanation:
To convert from atoms to moles, we must Avogadro's number:
6.022*10²³This number tells us the amount of particles (atoms, molecules, etc.) in 1 mole of a substance. In this case, it is atoms of magnesium in 1 mole.
6.022 *10²³ atoms Mg / 1 mol mgNow, let's set up an expression using:
[tex]\frac {6.022 * 10^ {23} \ atoms \ Mg}{ 1 \ mol \ Mg}[/tex]
Multiply this by the given number of atoms.
[tex]5.55*10^{25} \ atoms \ Mg *\frac {6.022 * 10^ {23} \ atoms \ Mg}{ 1 \ mol \ Mg}[/tex]
Flip the fraction so the atoms of magnesium can cancel.
[tex]5.55*10^{25} \ atoms \ Mg *\frac { 1 \ mol \ Mg }{6.022 * 10^ {23} \ atoms \ Mg}[/tex]
[tex]5.55*10^{25} *\frac { 1 \ mol \ Mg }{6.022 * 10^ {23}}[/tex]
Multiply and condense this into 1 fraction.
[tex]\frac { 5.55*10^{25} \ mol \ Mg }{6.022 * 10^ {23}}[/tex]
[tex]92.1620724 \ mol \ Mg[/tex]
The original measurement had 3 significant figures, so our answer must have that many as well. For the number we calculated, that is the tenth place. The 6 in the hundredth place tells us to round the 1 to a 2.
[tex]92.2 \ mol \ Mg[/tex]
It is about 92.2 moles of magnesium.

The original phase and final phase of a substance are shown. Phase Transition Original Phase Final Phase Solid Liquid What most likely happened during the phase transition?
Answer:
The question appears to speak to the process between Liquid and Solid phases of a substance and seeks to resolve what happened in between.
The short answer is that the solid melted.
Explanation:
Melting is the process of a solid becoming fluid. When the reverse happens, (that is a liquid being solid), is called solidification. There is a temperature at which substances take their liquid form. That temperature is called the melting point. The melting point of ice (that is the temperature at which it starts to turn back to water) for instance is 32 °F.
According to the mechanics of melting, the internal energy of the solid increases, because of exposure to heat and or pressure usually through the application of heat or pressure, which increases the substance's temperature to the melting point.
Cheers
Answer:
Explanation:
the other guy who answered must be retded cause melting isnt even a choice.
