The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches tha

t can be made from a set number of ingredients.
Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 52
slices of bread and 69
slices of cheese.

Answer:

Cheese will be limiting reactant.

Explanation:

In given question it is stated that two slices of breads are required for one sandwich. The total bread slices available are 52. we divide the 52 by 2 to determine the number of sandwich which could made from 52 slices.

52/2 = 26

26 sandwich could be made from 52 bread slices.

The amount of cheese required for one sandwich is 3 slices. The available slices of cheese are 69.

69/3 =  23

we can see that only 23 set of slices of cheese are available while bread slices are available for 26 sandwiches. so we can make only 23 sandwiches from given quantity of ingredients. The 6 slices or 3 set of bread will left, because cheese is limited.

What is the energy of a single photon of blue light with a wavelength of 488 nm (488 × 10-9 m)?
Vinvika [58]
E = hf

c = speed of electromagnetic wave, c ≈ 3 * 10⁸ m/s, 
Planck's constant h = 6.63 *10⁻³⁴ Js

h = Planck's constnat,  Frquency, f = c/λ = (3*10⁸)/(488*10⁻⁹)

E = hf

E = hc/λ

E = (6.63 * 10⁻³⁴ * 3 * 10⁸) /(488 * 10⁻⁹)

Energy, E ≈ 4.0758 * 10⁻¹⁹  Joules.

A compound 21.20% nitrogen 6.06% hydrogen 24.30% sulfur and 48.45% oxygen. Write the empirical formula and name the compound?
egoroff_w [7]

Greetings!

<h3>To find the empirical formula you need the relative atomic mass of each element!</h3>

N = 14

H = 1

S = 32.1

<h3>You can simply change the percentages into full grams</h3>

N = 12.20

H = 6.06

S = 48.45

<h3>Then you use this to find the Number of moles = amount in grams / atomic mass</h3>

N = 12.20 ÷ 14 = 0.8714

H = 6.06 ÷ 1 = 6.06

S = 48.45 ÷ 32.1 = 1.541

<h3>Then divide each number of moles by the smallest value:</h3>

N = 0.8714 ÷ 0.8714 = 1

H = 6.06 ÷ 0.8714 = 6.9 ≈ 7

S = 1.541 ÷ 0.8714 = 1.76 ≈ 2


So that means that there are 1 Nitrogen, 7 hydrogen, and 2 sulfur. This means the empirical formula would be:

NH₇S₂

How do protons determine element identity
Butoxors [25]

Answer:

The number of protons also determines the identity of the element. ... Since the atom is electrically neutral, the number of electrons must equal the number of protons.
