Answer:
1.2kg or 1200kg
Explanation:
F = ma
net force = 1,800
m = ??
a = 1.5m/s^2
m = F/a = 1,800/1.5 or 1,800 x 10/1.5 x 10
= 18,000/15 = 1,200kg or 1.2kg
Thanks
The mass is protons + neutrons
the number is protons/electrons
This is an incomplete question, here is a complete question.
The reduction of iron(III) oxide to iron during steel-making can be summarized by this sequence of reactions:
;
;
The net reaction is:
;
Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K be sure you use their standard symbols.
Answer : The equilibrium expression will be:
Explanation :
The intermediate reaction are:
(1) ;
(2) ;
The net reaction is:
;
Now we are multiplying reaction 1 by 3 and reaction 2 by 2 and then adding both the reaction we get the net reaction.
(1) ;
(2) ;
If the equation is multiplied by a factor of '2' or '3', the equilibrium constant will be the power of 2 or 3 of the equilibrium constant of initial reaction.
If the equations are added then the equilibrium constant of the reactions will be multiplied.
Thus the equilibrium expression will be:
Answer:
See attached picture.
Explanation:
Hello,
In this case, accounting for the IUPAC rules for the nomenclature of ketones, for the given name the structure is shown on the attached picture wherein the methyl is seen at the fourth carbon and the carbonyl at the second one in the 7-carbon chain.
Best regards.
Answer:
All the statements are correct but "all chemical reactions can be classified as one of the five general types".
Explanation:
Hello,
In this case, I assume you are looking for the wrong statement as long as the following ones are correct and matches with the foundations of chemical reactions:
- The only way to determine the products of a reaction is to carry out the reaction. This is clear, because after the chemical reaction is done, one identifies the products.
- Complete combustion has occurred when all the carbon in the product is in the form of carbon dioxide. This is clear due to a 100% conversion.
- A single reactant is the identifying characteristic of a decomposition reaction. All decomposition reactions have only one reactant which breaks into less complex species.
So the wrong statement is:
- All chemical reactions can be classified as one of five general types. This is wrong because there are four widely known chemical reactions: synthesis, decomposition, simple displacement and double displacement.
Best regards.
