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

Solve the equation 8(3x - 6) = 6(4x + 8). Does the equation have one solution, no solution, or infinitely many solutions? Explain. ( worth two point, answer and explanation)
⠀⠀⠀⠀
Equation have No solutions
⠀⠀⠀⠀
______________________
⠀⠀⠀⠀
➤ How to solve ?⠀⠀⠀⠀
For solving such problems we need to recall equations .
⠀⠀⠀⠀
When the value of two variable comes equal and zero in an equation then that equation is said to have infinitely many solutions . If the value of a variable have any particular constant then the equation is said to have one solution . If the value of of any variable comes undefine then the equation is said to have no solution .
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
⠀⠀⠀⠀
SolutiOn :➠ 8( 3x - 6 ) = 6(4x + 8 )
➠ 24x - 48 = 24x + 48
Now, we will bring the variable on left hand side and constants on right hand side
➠ 24x - 24x = 48 + 48
➠ 0 = 48 + 48
➠ 0 = 96
As we can see the equation have end with a undefined value the equation have no solutions
➠ No Solutions

Write the first five terms in the arithmetic sequence. f(n + 1) = f(n) – 19, f(1) = 34
Answer:
34, 15, -4, -23 and -42
Step-by-step explanation:
We are to find the first five sequence
when n = 1
f(2) = f(1) - 19
f(2) = 34 - 19
f(2) = 15
when n = 2
f(2+1) = f(2) - 19
f(3) = f(2) - 19
f(3) = 15 - 19
f(3) = -4
when n = 3
f(3+1) = f(3) - 19
f(4) = f(3) - 19
f(4) = -4 - 19
f(4) = -23
when n = 4
f(4+1) = f(4) - 19
f(5) = f(4) - 19
f(5) = -23 - 19
f(5) = -42
Hence the first five terms in the arithmetic sequence are 34, 15, -4, -23 and -42

A number line going from negative 1 to positive 1 in increments of 1. There are 5 equal spaces between each number. Select all the statements that are true. –1 is less than Negative StartFraction 4 Over 5 EndFraction. –0.3 is less than One-fifth. 0.6 is greater than 1. 0 is greater than –0.5. Negative three-fifths is equal to –0.6.
Answer:
–1 is less than Negative StartFraction 4 Over 5 EndFraction
Step-by-step explanation:
Number line from - 1 to + 1 in Increment of 1 ; with 5 equal spaces between each number ;
–0.3 is less than One-fifth
0 is greater than –0.5
Negative three-fifths is equal to –0.6
Number line :
-1 to 0 to 1
-1, - 0.8, - 0.6, - 0.4, - 0.2, 0, 0.2, 0.4, 0.6, 0.8, 1
–1 is less than Negative StartFraction 4 Over 5 EndFraction : - 1 < - 0.8 (true)
–0.3 is less than One-fifth : - 0.3 < 0.2 (true)
0.6 is greater than 1 ( false)
0 is greater than –0.5 (true)
Negative three-fifths is equal to –0.6; - 0.6 = - 0.6 ( true)

Step-by-step explanation:
The average daily maximum temperature in Cyprus is 21.85 degrees Celsius in the average daily minimum temperature is -4.7 degrees Celsius is the average daily maximum temperature is blank Celsius higher than the average daily minimum temperature
Answer:
26.55°C
Step-by-step explanation:
21.85 + 4.7
Average maximum daily temperature = 21.85°C
Average minimum temperature = - 4.7°C
The average daily maximum temperature is x°C higher than the average daily minimum temperature ;
x = (maximum temperature - minimum temperature)
x = (21.85 - (-4.7))°C
x = (21.85 + 4.7)°C
x = 26.55°C
Hence, The average daily maximum temperature is 26.55°C higher than the average daily minimum temperature

A horse at rest takes 60 breaths every 5 minutes. At this rate, in how many
minutes would the horse take 300 breaths?
1. 12 minutes
2. 25 minutes
3. 240 minutes
4. 3,600 minutes
Answer:
The correct answer is B. 25 minutes.
Step-by-step explanation:
Here, we know that a horse takes 60 breaths every 5 minutes. We need to find how many minutes it takes a horse to take 300 breaks. First, let's see how many times 60 can go into 300.
300 ÷ 60 = 5
Now, let's multiply this by 5.
5 x 5 = 25
Therefore, the answer is B. 25 minutes.
Hope this helps! :)
