Answer: 36.3 ml

Explanation:

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

n_1 = basicity H_2SO_4 = 2

M_1 = molarity of H_2SO_4 solution = 0.51 M

V_1 = volume of  H_2SO_4 solution = ?

n_2 = acidity of KOH = 1

M_1 = molarity of KOH solution = 0.36 M

V_1 = volume of  KOH solution = 103 ml

Putting in the values we get:

2\times 0.51\times V_1=1\times 0.36\times 103

V_1=36.3ml

Therefore, volume of H_2SO_4 required is 36.3 ml

Luis is helping his parents paint a border around the walls of a room. He uses a stencil to repeat the same design on each wall
iren [92.7K]

Answer:

Polymerization.

Explanation:

Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.

Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.

In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.

Polymerization is given by the chemical formula;

nA -----> A(n).

In this scenario, Luis uses a stencil to repeat the same design on each wall to form one long grapevine with a bunch of grapes every foot along its length.

Hence, the type of chemical reaction this best model is polymerization because it involved repeating the same design (monomers) to form a long grapevine with a bunch of grapes (polymers).

A slice of Swiss cheese contains 41 mg of sodium.
larisa86 [58]

Answer:

a. 41 mg equals 0.041 grams.

b. 41 mg equals 0.0014462 ounces

c. 41 mg equals 9.039*10⁻⁵ pounds

Explanation:

You know that a slice of Swiss cheese contains 41 mg of sodium.

a. What is this mass in grams?

Knowing that 1 mg = 10⁻³ g, you can apply the following rule of three: if 1 mg equals 10⁻³ g or 0.001 grams, 41 mg will be equivalent to how much mass in g?

mass=\frac{41 mg*0.001 g}{1 mg}

mass= 0.041 grams

<u><em> 41 mg equals 0.041 grams.</em></u>

b. What is this mass in ounces?

Knowing that 1 mg = 3.5274 * 10⁻⁵ ounces, you can apply the following rule of three: if 1 mg equals 3.5274 * 10⁻⁵ ounces, 41 mg will be equivalent to how much mass in ounces?

mass=\frac{41 mg*3.5274*10^{-5}ounces }{1 mg}

mass= 1.4462*10 ⁻³ ounces= 0.0014462 ounces

<u><em>41 mg equals 0.0014462 ounces</em></u>

c. What is this mass in pounds?

Knowing that 1 mg = 2.20462 * 10⁻⁶ pounds, you can apply the following rule of three: if 1 mg equals 2.20462 * 10⁻⁶ pounds, 41 mg will be equivalent to how much mass in pounds?

mass=\frac{41 mg*2.20462*10^{-6}pounds }{1 mg}

mass= 9.039*10⁻⁵ pounds

<u><em>41 mg equals 9.039*10⁻⁵ pounds</em></u>
