Why is magnesium malleable?
Answer:
It is an Alkaline Earth Metal
Explanation:
Metallic bonding results from the delocalization of electrons from the parent metal atom so that positive ions are conceived to swim in a sea of electrons. This view of metallic bonding accounts for the malleability, and ductility of metals, as well as their properties of thermal and electrical conduction.

A group of students conducted an experiment to find out what happens to the force of magnetism between two magnets as the distance between them increases. They used the equipment you see in the illustration. They
placed spacers between the magnet in the cup and the magnet on the post to increase the distance between them. They used washers as units to measure how much force it took to pull the two magnets apart.

Answer:
1. The organism becomes ill or may die.
2. Pathogens.
Explanation:
(1) When an organism fails to maintain homeostasis, the organism typically becomes ill, and they will die if homeostasis cannot be re-achieved.
(2) A pathogen is a virus that can cause diseases.
Consider the reaction Upper A u (upper O upper H) subscript 3 plus upper H upper I right arrow upper A U plus upper I subscript 2 plus upper H subscript 2 upper O.. Label the half-reactions as oxidation (use "O") or reduction (use "R"). 2 upper i right arrow upper I subscript 2 plus 2 e superscript minus. Upper A u superscript plus 3, plus 3 e superscript minus right arrow upper A u.
Answer:
2I- ---> I2 + 2e- = O
Au+3 + 3e- ---> Au = R
Explanation:
The first loses electrons, so it is Oxidized, and the second one gains electrons, so it is Reduced. (Also I just did this and saw the answers were O and R respectively)
Answer: o, r

what two subatomic particles have to be different in order to have an ion?
A)Protons and electrons
B)Protons and neutrons
C)Neutrons and electrons
Answer:
A)Protons and electrons
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
when an atom lose or gain the electron ions are formed and number of protons and electrons no longer remain the same.
For example:
An atom of sodium when lose one electron it form positive ion. The number of electrons became 10 and number of protons remain 11.
Na → Na⁺ + 1e⁻

Copper sulfate, when it is dissolved in water, has a blue color. When steel wool is mixed with a copper sulfate solution, the steel wool disappears, a brownish solid forms, and the color of the solution changes from blue to green.
Choose one answer that gives the best evidence that a chemical reaction took place.
A. The color change from blue to green happens in nature.
B. The disappearance of the steel wool shows that a new substance has formed.
C. The solid precipitate is a waste product in the reaction.
D. Energy is lost in this reaction like all other reactions.
Which answer did you choose? Explain your reasoning.
Answer:
A. The color change from blue to green happens in nature.
Explanation:
The color change is an indicator of a chemical reaction that has occurred. Although color changes are not necessarily good diagnostic tool to measure if a chemical reaction has occurred or not.
In this reaction, color changes is quite an effective tool Chemical changes usually involves the formation of a new product from the chemical reaction. Also, the steps are not easily reversible.For this reaction, color change is the most appropriate signal for a chemical change.The evidence that shows that a chemical reaction has taken place is the disappearance of the steel wool shows that a new substance has formed.
The electrochemical series is arrangement of elements in order of decreasing reactivity. It is important to note that the elements that are high up in the electrochemical series can displace the elements that are lower in the series from their aqueous solution.
Steel contains iron which lies above copper in the electrochemical series hence a chemical change occurs when steel dissolves in the copper solution.
Hence, the evidence that shows that a chemical reaction has taken place is the disappearance of the steel wool shows that a new substance has formed.

What happens to rock during subduction please help I will give you Brainlyest
Answer: Here is the answer!! :)
Explanation:
A subduction zone is a region of the earth's crust where one tectonic plate moves under another tectonic plate; oceanic crust gets recycled back into the mantle and continental crust gets created by the formation of arc magmas. ... This water lowers the melting point of mantle rock, initiating melting.

1. What are the reactants? What are the products? Use the reaction below (2pts)
Na + Cl2 → NaCl
2. Why do chemical reactions need to be balanced? (2pt)
3. In order to balance the following reaction, I need to add more Chlorine atoms to the product side. Would the highlighted answer be a correct way of adding more Chlorine atoms? Why or why not? (2pt)
Balanced: Na + Cl2 → NaCl2
4. Given the following reactions, what does the coefficient 2 represent for 2KI? (2pt)
Cl2 + 2 KI → 2 KCl + I2
Answer:
the reactants are na and cl2 the products is the combination nacl --the law of conservation of matter keeps reactions balanced. No you would not be adding more atoms that is what the first combo is. The coefficient 2 stands for 2 atoms of KL

If the concentration of Sn2+ in the cathode compartment is 1.10 M and the cell generates an emf of 0.22 V , what is the concentration of Pb2+ in the anode compartment?
Answer:
[Pb] = 1.1*10^-8
Explanation:
The Eo values of the half cell reaction of the following are
Pb2+ + 2e- ==> Pb . . .Eo = -0.13 V
Sn2+ + 2e- ==> Sn . . .Eo = -0.14 V
Sn+2 is at cathode(reduction)compartment and Pb+2 is at anode(oxidation) compartment.
the overall reaction will be
Pb ==> Pb2+ + 2e- (oxidation) Eo = +0.13 V
Sn2+ + 2e- ==> Sn (reduction) Eo = -0.14 V
----------------------------------------------------------------------
Pb + Sn2+ ==> Pb2+ + Sn Eo cell = -0.01 V
Qcell = [Pb+2] / [Sn+2] ( pure Sn , Pb do not appear in Q
Ecell = Eo -0.059/n* logQ
0.22 = -0.0.1 - 0.059/2 logQ
0.23 = -0.0295logQ
LogQ= -7.796
Q = 10^-7.796≈ 1/10^8
[Pb+2] / [Sn+2] = 1/10^8
[Pb] = 1.1*10^-8

Answer:
The waxy substance is warm.
The waxy substance is less dense than the surrounding liquid.
Convection is occurring.
Explanation:
Convection involves heat transfer by the actual movement of the particles of a substance.
When the wax is heated, the waxy substance becomes warm and rises in the lamp. The warm waxy substance is less dense than the surrounding liquid, this process of rising and falling is as a result of convection occurring in the lava lamp.
Answer:
The person above (or below) me is correct, the answer is:
B.) The waxy substance is warm.
C.) The waxy substance is less dense than the surrounding liquid.
E.) Convection is occurring.
