Answer:
The metal is Tin (Sn)
Explanation:
The following data were obtained from the question:
Mass of metal = 32.56 g
Volume of water = 14.78 mL
Volume of water + metal = 20.44 mL
Next, we shall determine the volume of the metal. This is illustrated below:
Volume of water = 14.78 mL
Volume of water + metal = 20.44 mL
Volume of metal =..?
Volume of metal = (Volume of water + metal) – (Volume of water )
Volume of metal = 20.44 – 14.78
Volume of metal = 5.66mL
Next, we shall determine the density of the metal.
Density of a substance is defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance is expressed as:
Density = Mass / volume
With the above formula, we can obtain the density of the metal as follow:
Mass of metal = 32.56 g
Volume of metal = 5.66mL
Density =.?
Density = Mass /volume
Density = 32.56g/5.66mL
Density of the metal = 5.75g/mL
Comparing the density of the metal with standard density of elements, the metal is Tin (Sn)
Dilution of the solution can be calculated by the formula of the molarity and volume. The initial volume of 2.50 M solution was 30 mL.
<h3>What is the relationship between molar concentration and dilution?</h3>
Molar concentration or the dilution factor is in an inverse relationship and with an increase in the dilution, the molarity of the solution decreases.
Given,
Initial molarity = 2.50 M
initial volume = ?
Final molarity = 0.750 M
Final volume = 100.0 ml
Substituting values in the formula:
Therefore, 30 mL was the initial volume of the solution before it was diluted.

Answer:
A
Explanation:
Nitrogen is an atom made up of 7 electrons.
To draw the orbital energy level diagram, let us write the orbital notation of the atom;
7 electrons of Nitrogen:
1s² 2s² 2p³
So,

Answer:
The majority of chemical processes are reactions that occur in solution. Important industrial processes often utilize solution chemistry. "Life" is the sum of a series of complex processes occurring in solution. Air, tap water, tincture of iodine, beverages, and household ammonia are common examples of solutions.Turpentine as a solvent are used in the production of paints, inks and dyes. ↔Water as a solvent is used in the making of food, textiles, soaps and detergents. ↔Alloys are solid solutions that are used in the manufacture of cars, aerospace and other vehicles.Household cleaners like bleach are solutions, they help us to make our houses clean. Beverages such as fizzy drinks, mineral water and tea are solutions. In hydroponics, the roots of plants are immersed in solutions containing dissolved mineral salts.
Answer:
3–methyl–2–butanol
Explanation:
To name the compound, we must:
1. Identify the functional group.
2. Give the functional group of the compound the lowest possible count.
3. Locate the longest continuous carbon chain. This gives the parent name of the compound.
4. Identify the substituent group attached.
5. Give the substituent group the lowest possible count.
6. Combine the above to get the name of the compound.
Now, let us obtain the name of the compound.
1. The functional group of the compound is Alcohol i.e —OH.
2. The functional group is located at carbon 2.
3. The longest continuous carbon chain is carbon 4 i.e butane. But the presence of the functional group i.e OH will replace the –e in butane with –ol. Therefore, the compound is butanol.
4. The substituent group attached is methyl i.e CH3.
5. The substituent group is located at carbon 3.
6. Therefore, the name of the compound is:
3–methyl–2–butanol.
