1. Four (4) is a coefficient found in which of the following
chemical formula?
a. 4KCN
b. 3K2PO3
C. 6(NH4)2PO4
d. 2KNO3
Answer:
a. 4KCN
Explanation:
Four is a coefficient found in the chemical formula 4KCN.
KCN is potassium cyanides.
A coefficient is a number that is written before a chemical compound. It is usually used to balanced reaction expression.
Chemically such numbers indicate the number of moles or volume of that specie.
Since KCN is the only compound with 4 before it, so, the solution is KCN

Which of the following describes a covalent bond?
Answer:
It is the sharing of electrons between atoms with an electronegativity difference below 1.7.
Explanation: Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond.
Answer: Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.
Explanation: A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

Answer:
C. the relative molecular mass of the compound
Explanation:
Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. To determine an empirical formula, the relative molecular mass of the composition of its elements can be used to mathematically determine their ratio.

Beryllium oxide is heated.
What is the chemical reaction equation?
Answer:
BeO
Reaction of beryllium with air
However, powdered beryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be3N2. Beryllium oxide is more normally made by heating beryllium carbonate. 2Be(s) + O2(g) → 2BeO(s)
Does the atomic number of an element equal the number of neutrons in an atom of that element?
Answer:
no
Explanation:
the atomic number the just the number below the symbol of the element as well as proton number or electron number, however if u want to work out the neutron number you have do mass number (which is on the top of the symbol) substact atomic number/proton number
Explain the origin of plate material (including the ocean floor and continents)
Answer:
the process involves plates being dragged into the mantle at certain points and moving away from each other at others, in what has been dubbed 'the conveyor belt'.
Plate tectonics depends on the inverse relationship between density of rocks and temperature.
At mid-oceanic ridges, rocks are hot and their density is low, making them buoyant or more able to float. As they move away from those ridges they cool down and their density increases until, where they become denser than the underlying hot mantle, they sink and are 'dragged' under.
But three to four billion years ago, Earth's interior was hotter, volcanic activity was more prominent and tectonic plates did not become cold and dense enough to spontaneously sank.
The movement of the seafloor away from spreading ridges caused by topographic variations (the ridge is a topographic high) and density changes in the crust (density increases as newly-formed crust cools and moves away from the ridge).
What is the origin of plate movement?The movement of the seafloor away from spreading ridges caused by topographic variations (the ridge is a topographic high) and density changes in the crust (density increases as newly-formed crust cools and moves away from the ridge).Geologists have discovered a new theory for the origin of plate tectonics. Researchers believe it was triggered by the spread of early continents and then evolved into a self-sustaining process.The continental crust is made up of granitic rocks, which are composed of relatively lightweight minerals like quartz and feldspar. The oceanic crust, on the other hand, is made up of basaltic rocks, which are much denser and heavier.To learn more about : Seafloor

Describe two patterns in the periodic table?
Answer:
Patter 1: Ionization Energy Decreases going down a group
Pattern 2: Ions tend to gain/lose the least amount of electrons
Take oxygen, for example. Oxygen has 8 electrons. To become like a noble gas it could either gain two to become like neon or it could lose six to become like helium. So what will oxygen do—gain two or lose six? As a general rule, atoms will gain or lose the fewest number of electrons possible.

Explanation:
Will is learning about a new kind of plastic used to make models. He learns that infrared light is absorbed by the plastic, X-ray light is transmitted through the plastic, and visible light is reflected off the plastic. Will wonders if the plastic will melt if he shines the lights on it. Can light cause the plastic to melt? Why or why not? Does it matter what type of light he shines on the plastic?
Answer: Yes, I think light can cause the plastic to melt, as long as the energy from the light is absorbed by the plastic.
Explanation:
Visible light will not melt the plastic because the energy does not pass through the plastic, it reflects off ensuring that the plastic does not absorb the energy. X-ray light is transmitted through the plastic, unlike the visible light, but the energy still isn't absorbed by it. The infrared light is the only one left, it is absorbed by the plastic allowing it to change and melt the material, unlike the visible and x-ray lights.
The plastic will melt if the energy from the light is absorbed by the plastic.
What are Electromagnetic radiations?These are forms of electromagnetic waves which propagate through space
and carry electromagnetic radiant energy. Examples include:
X-rayVisible lightInfrared etcVisible light and X-ray light won't melt the plastic as a result of the energy
not being absorbed whereas in the case of Infrared lights, the energy is
absorbed which will led to the melting of the plastic.
