Answer:The perimeter of the rectangle is $\frac{47}{3} inch$ or 15.66 inch.

Explanation:

Length of strip (I) = $2\frac{1}{2} inch=\frac{5}{2}inch$

Length of strip (II) = $5\frac{1}{3} inch=\frac{16}{3} inch$

According to question two strips of length $1 inch$ and two strips of lenght $\frac{5}{3} inch$ is used in making rectangle:

Perimeter of rectangle = Sum of all sides of rectangle

Perimeter of rectangle = $\frac{5}{2} inch+\frac{5}{2} inch +\frac{16}{3} inch+\frac{16}{3} inch=\frac{47}{3} inch$

The perimeter of the rectangle is $\frac{47}{3} inch$ or 15.66 inch.

Using the mmoles of (35)-2,2,-dibromo-3,4-dimethylpentane calculated earlier and the molecular weight of the product (962 g/mol)

Sedbober [7]

Answer:

The yield of the product in gram is $\mathsf{{w_P}=0.26 \ gram}$

Explanation:

Given that:

the molecular mass weight of the product = 96.2 g/mol

the molecular mass of the reagent (3S)-2,2,-dibromo-3,4-dimethylpentane is 257.997 g

given that the millimoles of the reagent = 2,7 millimoles = $2.7 \times 10^{-3} \ moles$

We know that:

Number of moles = mass/molar mass

Then:

$2.7 \times 10^{-3} = \dfrac{ mass}{257.997}$

$mass = 2.7 \times 10^{-3} \times 257.997$

mass = 0.697

Theoretical yield = (number of moles of the product/ number of moles of reactant) × 100

i.e

Theoretical yield = $\dfrac{n_P}{n_R}\times 100\%$

where;

$n_P = \dfrac{w_P}{m_P}$ and $n_R = \dfrac{w_R}{m_R}$

Theoretical yield = $\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%$

Given that the theoretical yield = 100%

Then:

$100\% =\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%$

$\dfrac{w_P}{m_P}=\dfrac{w_R}{m_R}$

${w_P}=\dfrac{w_R \times m_P}{m_R}$

where,

$w_P$ = derived weight of the product

$m_P =$ the molecular mass of the derived product

$m_R =$ the molecular mass of the reagent

$w_R$ = weight in a gram of the reagent

${w_P}=\dfrac{w_R \times m_P}{m_R}$

${w_P}=\dfrac{0.697 \times 96.2}{257.997}$

$\mathsf{{w_P}=0.26 \ gram}$

The 2 in the formula AgS is a<br>1. coeffcient<br>2. subscript<br>3. superscript<br>4. binomial

ludmilkaskok [199]

Answer:

Subscript, or B

Explanation:

<em>AgS is the equation for the chemic reaction of Silver + Sulfur, since the subscript of 2 goes by the g in the equation, this would equal subscript.</em>

<em />

<em>Remember subscripts are located at the BOTTOM of a coefficient and superscripts are located at the TOP of a coefficient.</em>

Is the distilled water/acidic/basic/netural?

SVEN [57.7K]

Distilled water is neutral, because the H+ and OH- ions are balanced. Litmus is a natural acid-base indicator extracted from a type of lichen.

if you had 16 tiles and each tile cost 80 cents how much change would you dmget back if you paid with 2 100 bills

olasank [31]

16 tiles x 0.80 = $12.80

If you have two 100 dollar bills, you have 200 dollars.

$200 - $12.80 = $187.20
