A calibration curve was created to determine the quantity of protein in a solution. The calibration curve has the form of a stra

ight line with the equation A = 0.0182 x +0.007 where A is the corrected absorbance of the solution and x is quantity of protein in the solution in units of micrograms (μg). Determine the quantity of protein in a solution that has an absorbance of 0.207. A blank solution has an absorbance of 0.050 .

Answer:

(a) 10 quantities of protein

(b) 2 quantities of protein

Explanation:

Given

A = 0.0182 x +0.007

Solving (a):

Solve for x when A = 0.207

Substitute 0.207 for A

A = 0.0182 x +0.007

0.207 = 0.0182x + 0.007

Solve for 0.0182x

0.0182x = 0.207 - 0.007

0.0182x = 0.200

Solve for x

x = 0.200/0.0182

x = 10.989010989

<em></em>x = 11<em> (Approximated)</em>

Solving (b):

Solve for x when A = 0.050

Substitute 0.050 for A

A = 0.0182 x +0.007

0.050 = 0.0182x + 0.007

Solve for 0.0182x

0.0182x = 0.050 - 0.007

0.0182x = 0.043

Solve for x

x = 0.043/0.0182

x = 2.36263736264

<em></em>x = 2<em> (Approximated)</em>

Why factory waste should be neutralized before disposing it into the water bodies?
Fudgin [204]

Explanation:

Factory wastes are usually acidic and they pose serious environmental challenges.

If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.

On land, the acid can enter into the soil and prevent plant growth.

Acid discharge can enter the groundwater system and render it unfit for use.

Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.

What are the 4 different types of bonds and how are they formed?
miv72 [106K]

There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.

To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:

Covalent is followed by ionic, hydrogen, and van der Waals.

andrezito [222]

1) list givens and convert if necessary

C₁ = 3.50 mol/L

V₁ = 0.550 L

C₂ = ?

V₂ = 0.275 L

2) rearrange formula

C_{1}V_{1}=C_{2}V_{2}\\\\C_{2}=\frac{C_{1}V_{1}}{V_{2}}

3) solve

C_{2}=\frac{(3.50\ mol/L)(0.550\ L)}{(0.275\ L)}

C₂ = 7.00 mol/L
