Answers
Answer:
1) 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.
2)A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
3)Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.

The melting of a glacier is an example of the interactions among which of Earth's spheres? geosphere, troposphere, cryosphere atmosphere, geosphere, cryosphere atmosphere, asthenosphere, biosphere hydrosphere, asthenosphere, atmosphere
Answers
Answer:
The melting of a glacier is an example of interaction among;
Hydrosphere, asthenosphere, atmosphere
Explanation:
The melting of a glacier is an example of the interactions among the Earth's cryosphere and hydrosphere
The cryosphere is described as the portions on Earth where water appears in solid (frozen) form such as glaciers, frozen grounds, snow covered land, sea ice, ice sheets, river ice, ice caps, etc.
The hydrosphere is all the forms water on a planet including, ice, liquid water and water vapor, therefore, the cryosphere is a part of the hydrosphere
The geosphere comprises the Earth's interior, including the asthenosphere, which is fluid and hot and therefore spread heat through both conduction and convection to the hydrosphere that raises the ocean temperatures and lead to glacier melting
The green house effect in the atmosphere results in global warming that raises the average temperature of the Earth which in turn raises the temperature of the oceans and the troposphere, resulting in melting of a glacier
Therefore, the melting of a glacier is an example of interaction among the hydrosphere, asthenosphere, and, atmosphere

In the above figure, what type of bond is formed?
metallic
ionic
covalent
nonpolar
Answers
Answer:
It is an covalent bond.
Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.

What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)
Answers
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

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.
