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 reaction

Answer:
x = 5
y = 2
Step-by-step explanation:
-3x + 3y = -9
3y = 3x - 9
Equation 1. <em><u>y = x - 3</u></em>
-3x + y = 7
Equation 2. <u><em>y = 3x + 7</em></u>
So, put number 1 equation to number 2's y :
x - 3 = 3x + 7
x -3x = 7 + 3
-2x = 10
2x = 10
x = 10/2
x = 5
And, put x, which is 5 , to the any equation to figure out the y.
This time, I'll use equation number 1.
y = 5 - 3
y = 2
Answer:
Olivia typed speed per minutes is 54 words
Step-by-step explanation:
Given:
Olivia typed 36 word in 2/3
Solution:
By Unitary method, calculate the speed of typing by Olivia as-
2/3 Minutes → 36 Words
1 Minutes → 36 ÷(2/3) Words
1 Minutes → 36x3÷2 Words
1 Minutes → 54 Words
Therefore Olivia typed speed is 54 word.
Answer:
(a) $2,375.
(b) $2,875.
Step-by-step explanation:
We have been general admission to The American Museum of Natural History is $19.
(a). To find the total cost of tickets for a group of 125 students, we will multiply 125 by $19.


Therefore, the total cost of 125 tickets would be $2,375.
(b). We have been given that the group also purchases IMAX movie tickets for an additional $4 per student.
The total cost of one ticket would be the cost of museum ticket plus movie ticket that is
.
The new total cost of 125 tickets would be 125 times $23.


Therefore, the new total cost of 125 tickets would be $2,875.
Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s
