Cylinder with a mass of 12g has a radius measuring 2cm and height of 6cm what is its density

lakkis [162]

Answer:

Given:

m = 12 g, the mass of the cylinder

r = 2 cm, the radius of the cylinder

h = 6 cm, the height of the cylinder.

Calculate the volume, V, of the cylinder.

V = πr²h

= π*(2 cm)²*(6 cm)

= 75.398 cm³

By definition,

density = mass/volume.

Therefore,

density = m/V

= (12 g)/(75.398 cm³)

= 0.159 g/cm³

= 0.16 g/cm³ (nearest hundredth)

Answer: 0.16 g/cm³

A student was comparing the solubility of equal amounts of table salt and table sugar at different temperatures.The table below

Mama L [17]

The sample that has the highest solubility is THE FIRST SAMPLE [TABLE SUGAR NO 1].
Solubility refers to the quantity of a solute that will dissolve in a given volume of solvent at a given temperature and pressure. The question above tells us that equal amounts of sugar and table salts were used. But looking at the table given in the question, you will see that sample 1 has the highest amount of solute that dissolve, that is 80, the rest of the samples have values that are lower than that.

Elza [17]

Answer:

Explanation:

Oleic acid originates from an unsaturated fatty acid with 18 carbon atoms and one double bond, which can be found in olive oil and many other vegetable and animal oils and fats. Its economic importance includes the production of soap making and cosmetics etc.

The line-bond structure of the given oleic acid in the question can be found in the attached below.

Predict the precipitate that will be formed in the following reaction:<br> NaF(aq) + AgNO3(aq) →

netineya [11]

The precipitate that will be formed : AgF

<h3>Further explanation</h3>

One indication of the double displacement reaction is the precipitation reaction

Solubility Rules:

• 1. soluble compound

All compounds of Li +, Na +, K +, Rb +, Cs +, and NH4 +

All compounds of NO₃⁻ and C₂H₃O₂⁻

Compounds of Cl−, Br−, I− except Ag⁺, Hg₂²⁺, Pb²⁺

Compounds of SO₄²⁻ except for Hg₂²⁺, Pb²⁺, Sr²⁺, Ba²⁺

• 2. insoluble compounds

Compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ +

Compounds of OH− except Compounds of Li +, Na +, K +, Rb +, Cs +, NH₄⁺, Sr²⁺, and Ba²⁺

Reaction

NaF(aq) + AgNO₃(aq) →NaNO₃(aq)+ AgF(s)

From the solubility rules above, it has been shown that the salts of the Ag⁺ cations are insoluble salts
