Which sentence best uses a split infinitive to clearly emphasize the message of safe driving? Before getting behind the wheel, y

ipn [44]

Young drivers must remember to always turn off cell phones before getting behind the wheel.

A split infinitive is often occurs when other words come between the two parts of the infinitive.They may look informal and result in confusion.

Split infinitive in a sentence can be handled by the rearrangement of the the sentence so that nothing is between the two parts of the infinitive.

Conclusively, we can say that split infinitive sometimes look informal and may result in confusion but it can be handle by rearranging the sentence.

Which pair shows equivalent expressions? mc019-1. Jpg mc019-2. Jpg mc019-3. Jpg mc019-4. Jpg.

Lubov Fominskaja [6]

A mathematical pair that is <u>equivalent</u> to the given expression $(4+6i)^2$ is -20 + 48i.

<u>Given the following expression:</u>

$(4+6i)^2$

To determine a mathematical pair that is equivalent to the given expression:

In this exercise, you're required to solve for a mathematical expression that is equivalent to the given expression. Thus, we would simplify the expression by applying the perfect-square trinomial.

<h3>The perfect square trinomial.</h3>

Mathematically, the perfect-square trinomial is given by this expression:

$(a+b)^2=a^2+2ab +b^2$

Comparing the expressions, we have:

a = 4

b = 6i

Substituting the values, we have:

$(4+6i)^2=4^2+2(4)(6i) +(6i)^2\\\\(4+6i)^2=16+48i +36i^2$

<u>Note:</u> $i^2$ = -1

Simplifying further, we have:

$(4+6i)^2=16+48i +36(-1)\\\\(4+6i)^2=16+48i -36\\\\(4+6i)^2=-20+48i$

if 45.4 grams of no and 12.1 grams of h2 react, what is the largest amount of ammonia that can be formed? the final answer shoul

meriva

Taking into account the reaction stoichiometry and limiting reagent, 25.73 grams of NH₃ are formed if 45.4 grams of NO and 12.1 grams of H₂ react.

<h3 /><h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

2 NO + 5 H₂ → 2 NH₃ + 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

NO: 2 moles
H₂: 5 moles
NH₃: 2 moles
H₂O: 2 moles

The molar mass of the compounds is:

NO: 30 g/mole
H₂: 2 g/mole
NH₃: 17 g/mole
H₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

NO: 2 moles× 30 g/mole= 60 grams
H₂: 5 moles× 2 g/mole= 10 grams
NH₃: 2 moles× 17 g/mole= 34 grams
H₂O: 2 moles× 18 g/mole= 36 grams

<h3>Limiting reagent</h3>

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

<h3>Determination of limiting reagent in this case</h3>

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 10 grams of H₂ reacts with 60 grams of NO, 12.1 grams of H₂ reacts with how many mass of NO?

$mass of NO=\frac{12.1 grams of H_{2}x 60 grams of NO }{10 grams of H_{2}}$

mass of NO= 72.6 grams

But 72.6 grams of NO are not available, 45.4 grams are available. Since you have less mass than you need to react with 12.1 grams of H₂, NO will be the limiting reagent.

<h3>Largest amount of ammonia formed</h3>

Using the amount of limiting reaction, the following rule of three can be applied: if by reaction stoichiometry 60 grams of NO form 34 grams of NH₃, 45.4 grams of NO form how much mass of NH₃?

$mass of NH_{3}= \frac{45.4 grams of NOx34 grams of NH_{3}}{60 grams of NO}$
