Answer:
Magma becomes rock after the heating process has settled.
Explanation:
Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.
The rock cycle explains the formation and breaking of the three forms of the rocks through various modes. The magma becomes rocks and magma again through the heating and cooling process.
What is magma?Magma has been the semi-hot liquid that is present in the mantle in the lithosphere of the earth. They have very high temperatures and can push through the crust in the form of volcanic eruptions.
The magma changes its form from semi-liquid to rocks and back to magma again through the rock cycle. The hot molten magma pushes through the crust, cools, and then forms rocks. These rocks after many years start melting at higher temperature or get deep down the mantle where it converts to semi-liquid again.
Therefore, the rock cycle converts the magma.

Answer:
Ans => C => 43.3%
Explanation:
2CO + O₂ => 2CO₂
Given 1g CO = 1g/28g·mol⁻¹ = 0.036 mol CO
b/c coefficient of CO = coefficient of CO₂ => moles CO₂ = 0.036 mol = 0.036mol x 44g/mol = 1.57 gCO₂ (theoretical yield)
%Yield = (actual yield/theoretical yield) x 100% = (0.68g/1.57g) x 100% = 43.3%

Marissa uses her bicycle to do a morning paper route. Starting at her home, she travels 3 km North, then 1 km East, then 3 km North, and lastly 1 km West. She completes the root in 1.5 hours. a. What is your displacement in regards to her home?
b. What is her velocity?
a. displacement = 6 km
b. velocity = 4 km/h
Further explanationGiven
a morning paper route
Required
displacement
velocity
Solution
Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
a. Since we only consider the starting point and the end point, we just need to add up the distances to the north
3 km + 3 km = 6 km
b. Velocity = displacement changes with time
[tex]\tt v=\dfrac{d}{t}=\dfrac{6~km}{1.5}=4~km/h[/tex]

What number of cations is present in 1.17g of sodium chloride ?
Answer:
1.2 × 10^22 atoms.
Explanation:
Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.
Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mole = mass/molar mass
Mole = 1.17/58.5
Mole = 0.02moles
Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.
In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+
0.1204 × 10^23 atoms
1.2 × 10^22 atoms of Na+ (cation)

How is a carbon atom different from a hydrogen atom?
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
The carbon atom different from a hydrogen atom, because the atomic number of hydrogen is 1 . The atomic mass number of hydrogen is also one. For the carbon atom, the atomic number is 6, and the atomic mass number of carbon is 12.
What is an atomic number ?The term atomic number is defined as the number of a chemical element in the periodic system. The elements are arranged in order of increasing number of protons in the nucleus.
The atomic number is situated at the upper left, or number of protons. In the middle is the letter symbol for the element. Atomic number is equal to the proton number or the number of protons found in the nucleus of every atom of that element.
Thus, Carbon atom is a chemical element with the symbol C and atomic number 6. Whereas hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron and its symbol is H.

. A skydiver jumps from an airplane and opens his parachute. At some point during his fall, the downward force of gravity on the skydiver is equal to the upward force of drag on the parachute. Which of the following best describes the skydiver's motion at this point? The skydiver is gaining speed downward. The skydiver is moving at a constant speed. The skydiver is decreasing in speed.
The upward drag and downward force is equal for the skydiver when he jumps down from the plane. Thus, he experiences a constant speed through out his motion.
What is gravitational force?Gravitational force is a kind of force by which a body attracts other objects into its center of mass. Force exerted by the body depends on the mass and distance to it.
Earth pull every objects into its surface by gravitational fore of attraction. For moving body the the gravitational force acting downward have an acceleration due to gravity.
The skydiver experiences a force upward by the drag of a the parachute. When this force becomes equal to the downward fore of gravity, then his speed will be constant thus, no gain or lose for speed.

The term "alchemy" refers to early pseudoscientific attempts to transform common
elements into more valuable elements (such as lead into gold), For one kind of atom to
become another kind of atom, which particle(s) of the atom need to be expelled or gained?
Proton
Electron
Neutron
Quantum Particles
Answer: The correct answer is option B. electron.
Explanation:
There are 3 subatomic particles:
Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.Protons: They carry positive charge and are present inside the nucleus of an atomNeutrons: They does not carry any charge and are present inside the nucleus of an atom.An atom forms an ion, when it looses or gains an electron.
When an atom looses electron, it form a positive ion known as cation.When an atom gains electron, it form a negative ion known as anion.Hence, the correct answer is option B. electron.
The particle(s) of the atom that is needed to be expelled or gained in an alchemy process which involves transformation of one element into valuable elements or atom to another is B:Electron.
Alchemy can be regarded as branch of philosophical and protoscientific tradition that is traceable to China, and Europe. In the process of transformation of one element to another useful element or compounds , there is usually transfer of electron.Electronegative element like chlorine usually gain electron and are anion, while electropositive elements like potassium will loose electron( cation) all involves the transfer of electron.
Therefore, option B is correct.
