Explanation:
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.

Answer:
Magnesium hydroxide has 3 unique elements.
Explanation:
Long story short, 2 is the balancing compound in structure to make up hydroxide, therefore 1 compound would be left to create Mg(2O)H.

Cyanobacteria use the process of
to produce energy, and oxygen is given off as a waste product.
Answer:
Photosynthesis utilizes water as an electron donor in cyanobacteria in general and creates oxygen as a by-product, although some can even use hydrogen sulfide, a process that occurs among other photosynthetic bacteria, such as purple sulfur bacteria. Carbon dioxide is reduced via the Calvin cycle to form carbohydrates.

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:
1.39 × 10²³ molecules of CaCl₂
Explanation:
Given data:
Number of moles of CaCl₂ = 0.23 mol
Number of molecules = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
0.23 mol × 6.022 × 10²³ molecules / 1mol
1.39 × 10²³ molecules

How many kilo joules of heat are required to the decompost 1.96 mol Nah I 3(s)
Heat required = = 126.42 kJ
Further explanationGiven
1.96 mol NaHCO₃(s)
Required
Heat needed
Solution
Reaction( decomposition of Baking soda (NaHCO₃) :
2NaHCO₃ (s) + 129 kJ ⇒ Na₂CO₃ (s) + H₂O (g) + CO₂ (g)
For 2 mol NaHCO₃ , heat needed = 129 kJ
conversion factor :
[tex]\tt \dfrac{129~kJ}{2~mol}[/tex]
So for 1.96 mol :
= 1.96 mol x (129 kJ/2 mol)
= 126.42 kJ

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.
