Prove this reaction is a redox reaction
3 Mg + 2 FeCl3 +2 Fe + 3 MgCl2
Your answer should include the half equations
Answers
Answer:
because Redox means two words:reduction and oxidation
reduction is when oxygen is taken from a substance while oxidation is the addition of oxygen to a substance..Magnesium displaces chlorine from iron(fe)because it is more reactive than iron
and iron gives chlorine to magnesium because it's less reactive.This is due to their position on reactivity series.
Explanation:
This is called displacement reaction where by A most reactive metal remove a substance from a less reactive metal and form up a salt
and in this case the salt formed in the reaction is 3MgCl

what is the final equation?
_ Na+Cl 2 -> _NaCl
Answers
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2

Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answers
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.

Answers
Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]
For the given chemical reaction:
[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]
The expression for [tex]K_p[/tex] in terms of gaseous is written as:
[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answers
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Which set up would correctly complete the work for determining how many moles of NaOH will be produced if 10.5 grams of water (H2O) is used?
Answers
Answer:
B: 2 mol NaOH/2 mol H2O
Explanation:
The reaction equation is;
H2SO4 + 2NaOH = Na2SO4 + 2H20
Now, to know how many moles of NaOH will be produced for 10.5 grams of water (H2O) used, and since the molar mass of H2O is 18.02 g/mol and number of moles attached to H2O and NaOH in the reaction are both 2 we will have;
10.5g H2O × 1 mol H2O/18.02 g H2O × 2 mol NaOH/2 mol H2O
Thus correct answer is option B
true or false, when something heats up, new energy is created, and when something cools down, energy is destroyed.

Answers
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.

How many grams of carbon dioxide would 6.0E25 molecules be?
Answers

4383.28 g
Explanation:
First we'll need to convert molecules into moles, we can do so using Avogadro's number:
6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 molesThen we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:
99.62 moles CO₂ * 44 g/mol = 4383.28 g
