Answer:
Cl2 acts as an oxidizing agent
Explanation:
The balanced equation is
Cl2+NaOH⟶NaCl+NaClO3+H2O
Cl2 acts as a reactant in this chemical reaction
Cl2 receives one electron and thus reduces itself from Cl2 to 2 Cl−. This indicates that 2Cl- will oxidize some other element and hence Cl2 act as an oxidizing agent.
List the following elements from increasing electronegativity: boron, magnesium, calcium, chlorine, argon
Answer:
The list of elements from increasing electronegativity: Calcium < magnesium < chlorine < argon < boron.
Explanation:
In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.
Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.

When are atoms considered stable?
when they have satisfied the law of conservation of mass naturally or through bonding to obtain
full valence shells
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
when their valence electrons have "fallen" back to ground state through bonding
Answer:
when they have satisfied the octet rule naturally or through bonding to obtain full valence shells
Explanation:
Generally, most atoms of an element are unstable because they have a void in their electron shell to fill, hence, they need to react with other elements to fulfil this task of octet.
Octet rule states that atoms of elements engage in reactions to form compounds so they can have eight (8) valence electrons in their shell. Noble gases e.g argon, neon etc. are elements that have naturally satisfied this octet rule by possession of 8 valence electrons in their shell. Other elements that do not have this naturally becomes reactive and enter bonding with other atoms to obtain full valence shells.
Which of the following equations is balanced?

Answer:
4Na + O2 - 2Na20Is the balanced equations .
How can you provide a better explanation of what was happening that made the pie pans fly off the Van de Graaff generator?
Answer:
Due to repulsion.
Explanation:
Repulsion among electrons is responsible for fly off the pie pans from the Van de Graaff generator. When the globe of the generator charges up, the charge will move to the top part of the pie tin. The top region of pie tin accumulates charge and since it is not fixed at one place like upper half of the globe itself, it will be repelled by electrostatic forces between electrons that leads to fly off so we can say that similar charge of electrons is responsible for this fly off.
What is the [OH-] in a solution that has a pH = 9.23? *
O 1.7x10^5
O 8.2x10^-9
1.7x10^--5 M.
Answer: 1.7x10^-5
Explanation:
pH + pOH = 14
14 - pH = pOH
14 - 9.23 = 4.77
pOH =4.77
[OH-] = 10^-pOH
= 10^-4.77
= 1.698243x10^-5
= 1.7x10^-5

What is the molarity of a solution which contains 0.80 mol of HCl in 250mL of
solution?
Answer:
3.2M HCl Solution
Explanation:
Molarity = moles of solute / volume of solution expressed in liters
moles of solute = 0.80 moles HCl
volume of solution = 250 ml = 0.250 Liter
Molarity (M) = 0.80 moles HCl / 0.250 Liters = 3.2M HCl Solution

Explanation:
Students investigating chemical reactions conducted the experiment you see here. An antacid tablet was dropped into a plastic bag containing 10 ml distilled water at 22oC. The bag was immediately zipped closed and the chemical reaction proceeded until completion. Based on your knowledge of chemical reactions, choose all of the statements below would apply?
A) the tablet completely disappeared.
B) The total mass at the completion of the experiment is 16.72g.
C) The mass of the products is slightly less than the mass of the reactants.
D) A decrease in the mass of the products in the result of the production of a gas.
E) Evidence of a chemical reaction includes the production of something new: a gas
Answer: B and E
Explanation:
The chemical reactions are all around us. Here for the given reaction the tablet completely disappeared and evidence of a chemical reaction includes the production of something new: a gas. The correct options are A and E.
A chemical reaction is defined as the reaction in which the bonds are broken within the reactant molecules and the new bonds are formed within the product molecules. In a chemical reaction the compounds interact to form new substances called products.
In a chemical reaction, a chemical change must occur which is generally observed with precipitation, heat formation, etc.
Thus the correct statements are options A and E.

A 2.25 mol sample of oxygen occupies 1.80 L at 25.0°C. What volume will
it occupy with 3.7 moles?
Answer:
2.96 L
Explanation:
We apply the Ideal Gases Law to determine this:
P . V = n . R . T
Firstly we need to know the pressure for the 2.25 moles
P . 1.80L = 2.25 mol . 0.082 L.atm/mol.K . 298K
(We convert T°C to T°K, 25°C + 273 = 298K)
P = (2.25 mol . 0.082 L.atm/mol.K . 298K) / 1.80L
P = 30.5 atm
So now, we apply the pressure value for the new conditions:
30.5 atm . V = 3.7 mol . 0.082 . 298K
V = (3.7 mol . 0.082 . 298K) / 30.5atm = 2.96 L
What type of reaction is this?
Answer:
Decomposition

"Reduce, reuse, recycle." Give examples of how one or more of
these ideas can be applied to the issues and practices of hydraulic
fracturing for the acquisition of shale gas.
Answer:
Examples of how the ideas can be applied to the issues and practices of hydraulic fracturing for the acquisition of shale gas are;
Reuse; The produced water in obtained from oil and gas well production are reused for fracking, drilling, and if the water is good enough, it can be used for farming
Reduce; The use of recycled brine and water in drilling and fracking process reduces the application of freshwater in the those processes and reduces pollution of natural water sources
Recycle; Recycling involves creating products from waste. In the hydraulic fracturing process approximately 13 percent of the water produced and the flowback water are recycled to be used more than once thereby reducing the net consumption of freshwater
Explanation:
In hydraulic fracturing, also known informally as fracking, is the drilling method used in oil and gas well development process that makes use of water sand and chemical injection through the well bore to open and widen cracks in the bedrock formations in the areas around the wellbore.

Explanation:
A student measures out 5 mL of calcium chloride solution into a small container and 5 mL of sodium carbonate solution in another small container. The total mass of both chemicals and the containers they are in is 15.5 g. When the student combined the two clear liquids, a gooey, cloudy precipitate formed. What would the total mass of the products and the two containers be after this reaction took place?
Answer:
15.5g
Explanation:
"The total mass of both chemicals and the containers they are in is 15.5 g." After a chemical reaction, by conservation of mass, the total mass of the products and the two containers after reaction is the same at 15.5g.
Answer:
15.5
Explanation:
in a chemical reaction, mass is conserved
so mass after reaction = mass before reaction = 15.5 g
