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 44 slices of bread and 69 slices of cheese.

Answer:

Slices of bread will limit the number of sandwiches that can be made.

The quantity of ingredient in excess remains is 3 slices of cheese.

Step-by-step explanation:

The reagent that is present in less amount in the reaction mixture is called limiting reagent. It gets exhausted at the end of the reaction. Limiting reagent governs the formation of products.

Given:

2 slices of bread with 3 slices of cheese consists of 1 sandwich.

It can also be written as:

1 slice of bread with 3/2 slices of cheese consists of 1/2 sandwich.

Or,

1 slice of bread with 1.5 slices of cheese consists of 0.5 sandwich.

44 slices of bread with 1.5*44 slices of cheese consists of 0.5*44 sandwich.

So,

44 slices of bread by using 66 slices of cheese, 22 sandwiches can be made.

Since, we have 69 slices of cheese and we have to use only 66 slices of cheese. It is present in excess.

<u>So, slices of bread will limit the number of sandwiches that can be made.</u>

<u>Also, the quantity of ingredient in excess remains is 3 (69-66) slices of cheese.</u>

Si una galleta de chocolate aporta un aproximado de 150 kcal y un viaje en bicicleta se quema por media hora se que mas 340 kcal
Elanso [62]

Answer:

Una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Step-by-step explanation:

De acuerdo con este problema, la cantidad de calorías que se quema es directamente proporcional al tiempo de viaje en bicicleta. Si sabemos que una galleta aporta 150 kilocalorías, entonces 5 galletas equivalen a 750 kilocalorías.

Por regla de tres simple calculamos el tiempo requerido para quemar 750 kilocalorías:

x = 30\,min \times \frac{750\,kcal}{150\,kcal}

x = 150\,min

Es decir, una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Anybody know number 11??
PIT_PIT [208]

The property shown in #11 is the Associative Property of Addition.

In short, the associative property of addition states that no matter how an additive expression is grouped, the quantity will turn out the same. In this case, the answer is going to be equal whether you decide to add 5 and 8 first or 8 and 11 first.

5 men take 45hours to build a wall.how long will it take 9men working at the same wall?​
Karolina [17]

Answer:

<u>25 hours</u>

Step-by-step explanation:

It takes 5 men 45 hours to build a wall.

So, if no. of men increases by 1.8 [∴ 5 x 1.8 = 9],

then time taken reduces by that same amount.

=> 45 hours / 1.8

=> 45 / (9/5)

=> 45 x 5 / 9

=> 5 x 5

=> <u>25 hours</u>

Which statement describes the translation of y = −one half (x − 2)2 − 2 from standard position?
kaheart [24]
A quadratic in vertex form can be represented as

y = a(x-h)^{2} +k

a represents reflection over the x-axis, and a vertical stretch or compress 
- is reflection and a fraction (1/2) represents a compression.

-h represents a shift of that many units to the right (-2 shifts to the right  two units)

k represents a shift up or down (-2 is shifting down 2 units_

Reflected over the x-axis, Vertically compressed by a factor of 1/2, shifted 2 units to the right, and shifted 2 units down
