Aluminum is often used in the structure of light-weight bicycle frames. How many
Brilliant_brown [7]

Answer:

The first thing that you need to do here is to figure out the mass of the sample.

To do that, you can use its volume and the fact that aluminium is said to have a density of

2.702 g cm

−

3

, which implies that every

1 cm

3

of aluminium has a mass of

2.702 g

.

What property of water molecules allows water to dissolve many substances
hodyreva [135]

Answer:

Its high polarity

Explanation:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.

A mixture of 18 % 18% disinfectant solution is to be made from 16 % 16% and 23 % 23% disinfectant solutions. How much of each so
jeka94

Answer: 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.

Explanation:

According to the dilution law,

C_1V_1+C_2V_2=C_3V_3

where,

C_1 = concentration of ist disinfectant solution = 16 %

V_1 = volume of pure acid solution = x gallons

C_2 = concentration of another disinfectant solution= 23%

V_2 = volume of another acid solution= (28-x) gallons

C_3 = concentration of resulting disinfectant solution = 18 %

V_1 = volume of resulting acid solution = 28 gallons

16\times x+23\times (28-x)=18\times 28

x=20galllons

(28-x) = (28-20) = 8 gallons

Thus 20 gallons of 16% and 8 gallons of 23% solution is usedfor 28 gallons of the 18 % solution.
