what is excess reagent
Answer:
We are commonly asked to find the extra reactants in a chemical equation. We can find it after balancing the equation and seeing the amount of moles that are present for each substance. Hence in chemistry and thermodynamic reactions it is the extra reactants that are not used up during the combustion process and therefore is excess of a said element.There are also limiting reagent which is the substance that limits the amount that can react and can be produced in a chemical reactionRate positively and give brainlist
The limiting reagent in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
why is excess reagent used:
A good way to ensure that one reactant fully reacts is to use an excess of the other reactant. This is financially efficient when one of the reactants is very cheap. When one reactant is in excess, there will always be some left over.
how do you find the excess reagent:
The reactant that produces a lesser amount of product is the limiting reagent. The reactant that produces a larger amount of product is the excess reagent. To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given
The number of tickets sold on Saturday for the school play was 175 percent of the ticket sales on Friday. If 400 tickets were sold on Friday, how many tickets were sold on Saturday?
Answer:

What is the length of the hypotenuse?
Answer:
50ft
Step-by-step explanation:
use the Pythagorean theorem 14 squared + 48 squared equals 2500 square root of 2500 equals c squared the square root of 2500 is 50
Answer:
50
the Pythagorean theorem states that the hypotenuse of a triangle squared is equal to the sums of the other 2 sides squared.
it can be expressed as so:
c^2=a^2+b^2
therefore
c^2=14^2+48^2
C^2= 196+2304
c^2=2500
square root of 2500 is 50
50=the hypotenuse.

If R is the midpoint of TS, TR = 5x - 12, and RS = 3x + 8, find TS.
Answer:
5x -12 = 3x +8 (set the two = each other because they are the same length)
2x- 12= 8 (subtract 3x from both sides)
2x = 20 (add 12 to both sides)
x=10 (what x= for both expressions)
5(10) -12 (plug it into the first one to see what the length is and to see they're =
50 - 12 ( I already multiplied, now subtract)
38 (what the length of TR is)
3(10) +8 (plug it in again but into the other expression)
30+8 (multiply and add)
38 (the two have the same answer, so the x-value is correct.)
38+38= 76 (add the lengths of RS and TR and you get the length of TS)
Step-by-step explanation:
I hope this helps :)
Applying the segment addition theorem, the value of TS is: 76
Given:
TR = 5x - 12
RS = 3x + 8
If T is the midpoint of TS, therefore we would have the following equation:
TR = RS
Plug in the expressions5x - 12 = 3x + 8
Add like terms together5x - 3x = 12 + 8
2x = 20
Divide both sides by 2x = 10
TS = TR + RS (segment addition theorem)
SubstituteTS = 5x - 12 + 3x + 8
Plug in the value of xTS = 5(10) - 12 + 3(10) + 8
TS = 50 - 12 + 30 + 8
TS = 76

Solve: -1/2x +2=-x+7
Answer:
x = 10
Step-by-step explanation:
-1/2x + 2 = -x + 7
multiply by 2 so that -1/2x becomes -x
(-1/2x + 2 = -x + 7)2
-x + 4 = -2x + 14
subtract 4 from both sides
-x = -2x + 10
add -2x to both sides
x = 10

Answer:
k = -1
Step-by-step explanation:
Subtract 10 and simplify. We choose this value so the constants on the right add up to give 0.
3 -10 = 3 + 7k + 7 -10
-7 = 7k
Divide by 7.
-7/7 = 7k/7
-1 = k

1. Fiona Wolfe regular pay is $9 an hour and time-and-a-half for anything over 40 hours. Last week she worked 46 hours at her full-time job. She also worked 7 hours last week at a part-time job that pays $11 an hour. What total gross pay did she earn last week from both jobs?
Answer:
$518
Step-by-step explanation:
The total gross payment = full-time payment + part-time payment
Given that:
She worked 46 hours for her full-time payment and time-and-a-half for anything and she is being paid $9 per hour;
and also worked for 7 hours for her part-time payment and she is being paid $11 per hour and time-and-a-half for anything
Then, the total gross payment = $46(9 1/2) + $7(11 1/2)
The total gross payment = $46(9.5) + $7(11.5)
The total gross payment = $437 + $80.5
The total gross payment = $517.5
The total gross payment ≅ $518

How many solutions does 46x– 23 = 46x + 23 have
Answer:
no solution
Step-by-step explanation:
Let's first try to solve this.
Notice that there is a 46x term on both sides, so we can subtract both sides by 46x, leaving us with:
-23 = 23
Well... this is a false statement: -23 does not equal 23.
Thus, this as no solution.
Answer:
No solutions found
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
46*x - 23 - (46*x + 23) = 0
Equations that are never true
Solve : -46 = 0
This equation has no solution.
A non-zero constant never equals zero.
