is CuO a covalent or ionic bond?
The electronegativity is less than 1.7, which would make it a covalent bond. But I am still not sure..
Answer:
it would be ionic
copper forms a cation and oxygen forms an anion
those charges represent the e-s that are transferred during bonding
oxygen is -2 so will accept 2 e-s to achieve noble gas configuration

Which of the following is an example of an adaptation that might be useful in the grassland? HELP ME PLS
A. an insect looking like a tree branch
B. an animal having a heavy coat of fur
C. an animal having large feet so it can walk on the snow
D. an animal being the color of brown grass and dust
Answer:
D
Explanation:
In the grassland pretty warm so the heavy fur coat wouldn't help, there is no snow in the grassland so the big feet for walking on snow also wouldn't help, its the grassland where trees are more scarce so not A, but there is a lot of grass and dust so being able to blend in would help.
Answer:
D
Explanation:
AN animal this color can camouflage and it can help them so they will not be eaten by there predators

Which of the following has the smallest atomic radius?
a B
b Al
c F
d N
e Ga
Answer:
c. F
Explanation:
As you go top to bottom down a column of the periodic table, atomic radius increases.
As you go left to right across a period of the periodic table, atomic radius decreases.
Knowing this trend, that means that the smallest atomic radius would be located in the top right of the periodic table. The closest element to that point is fluorine, or answer C.

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.
What is metal ?A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.
These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.
The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.
Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

______ meters = 177 millimeters
Answer:
117 millimeters = 0.117 meters
Explanation:
This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.

Answer:
What substance changed physically under all three condition? Copper Wire
What substance changed chemically under all three condition? Steel Wool
What evidence indicates a chemical reaction is occurring? New gases are produced; A phase change has occurred; A color change
Select the three answers that are examples of a chemical reaction. The mixing of an acid and base shows an increase in temperature; after baking bread there is a new odor or smell; when hair is bleached it changes to a lighter color
Which data supports this inference? Baking soda dissolving; A gas formed, creating bubbles
Which experiment best shows evidence of energy being released in a chemical reaction? Heat and light are given off when paper is burned
Which experiment likely resulted in the formation of a precipitate? Two solutions are mixed together and a yellow solid forms
The BEST evidence for a chemical reaction is the formation of a new substance.
Explanation:
2. When heat and light are being given off, energy is being released. Paper burning is a chemical reaction b/c when paper is burnt, it is a new substance and the act can't be undone.
3. When a yellow solid forms, that solid is the participate.
4. You will for sure have a chemical reaction if a new substance is created.
5. Copper wire changed physically b/c the copper wire can be returned to its original condition in all of these situations and no new substance was formed. Steel Wool changed chemically b/c it can't be returned to its original state under any condition and new substances were formed every time.
6. New substances formed indicate a chemical reaction. A color change also is an indication of a chemical reaction.
7. When a substance can't be turned into its original position or a new substance is produced, a chemical reaction occurred.

What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)
Answer:
the mass of 8.03 mole of NH3 is 136.51 g
Explanation:
The computation of the mass is shown below:
As we know that
Mass = number of moles × molar mass
= 8.03 mol × 17 g/mol
= 136.51 g
Hence, the mass of 8.03 mole of NH3 is 136.51 g
We simply multiplied the number of moles with the molar mass so that the mass could come

Which statement can be applied to an atom of neon?
A The atom has the same electron arrangement as Cl– ion.
B The atom has two more electrons than an atom of oxygen.
C The atom has the same number of outer electrons as an atom of helium.
D The atom has the same number of electrons as a Ca2+ ion.
Answer:
B. The atom has two more electrons than an atom of oxygen.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
This ultimately implies that, an [tex] O^{2-} [/tex] atom contains the same number of electrons as an atom of neon.
Hence, a neon atom has two more electrons than an atom of oxygen.
Additionally, Neon is used in lighting advertising displays.
