The insects have been defined as the most successful arthropods. There are far more species in the class Insecta than in any other group of animals. The insects are the only invertebrates with wings.

What are insects?

The insects play a very important role in the web of the life in every environment. Their jobs include pollinating flowering plants, since it is the source of food for insectivorous animals and it assist in the decomposition of plants and animals.

The two different methods which help to identify the species of the insects from the eggs on human remains are by using a small paint brush dipped in water and the other way is by using the forceps.

The study of insects and their life cycle are found to be important for the forensic entomologist. This is because it could set a timeline on when the crime is happened. The life cycle of a blowfly starts as an egg and then goes to be maggots.

a. An undesirable constituent of air​

Answers

Complete Question:

Give one word for the following.

a. An undesirable constituent of air

b. The constituent of air that helps in burning

c. The thick layer of air surrounding the earth

d. Carbon dioxide does not support this process​

Answer:

a. Pollutant.

b. Oxygen.

c. Atmosphere.

d. Combustion.

Explanation:

a. Pollutant: an undesirable constituent of air. Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances known as pollutants. Some examples of pollutant are carbon monoxide, nitrogen dioxide, ozone, etc.

b. Oxygen: the constituent of air that helps in burning. Oxygen is an element that aids in the combustion (burning) process because it is an oxidizing agent.

c. Atmosphere: the thick layer of air surrounding the earth. It comprises of nitrogen, oxygen, carbon dioxide, argon and other gases in very small proportion.

d. Combustion (burning): Carbon dioxide does not support this process but it is an end product of the process.

Combustion can be defined as an exothermic chemical reaction between physical substances, usually in the presence of oxygen and hydrocarbons to produce heat, light and carbon.

What mass of iron is formed when 240 g of iron(III) oxide reacts completely with carbon monoxide?

Answers

Answer:

168 g

Reaction:

[tex]Fe_{2}O_{3} + 3 CO >>> 2 Fe + 3CO_{2}[/tex]

Explanation:

First we need to figure out what is the formula mass (Mr) of Fe2O3 (Iron(III) oxide).

The atomic mass of Fe=56, O=16

Mr= 56+56+16+16+16=160 g/mol

We can now figure out the moles of the iron:

240/160 = 1.5 mol

Then we need to find the ratio to make Fe.

In the reaction, we know that 1 mole of Fe2O3 can make 2 moles of Fe. So 1.5 moles of Fe2O3 can make 3 moles of Fe.

And then we need to find the mass of the Fe.

3×56=168 g.

Hence 168g of the iron is made after the reaction.

If water is added to 145 mL of a 0.55 M KOH solution until the volume is 250 mL, what will the molarity of the diluted solution be?

Answers

Answer:

0.319 M

Explanation:

M1V1 = M2V2

M1 = 0.55M

V1=145 mL = 0.145 L

V2 = 250mL = 0.250L

M2 = M1V1/V2=0.55x0.145/0.250 = 0.319 M

what happens when bromine water is added to ethane and ethene​

Answers

Answer:

Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction is known as electrophilic addition.

Explanation:

Ethene will readily react with bromine, so the colour of the bromine water changes from red-brown to colourless. Bromine atoms will add across the double bond in ethene to produce just one product; 1,2-dibromoethane.

a 31 g sample of a compound that contained only

Answers

The question is incomplete, the complete question is;

A 31 g sample of a compound that contains only the elements C,H and N is completely burned in O2 to produce 44.0 g of CO2, 45.0 g of H2O, and 92.0 g of NO2. Determine the empirical formula of the compound.

Answer:

CH5N2

Explanation:.

Mass of C = 44.0g/44.0 g/mol = 1 mol * 1 = 1 mole of C

Mass of H = 45.0 g/18 g/mol = 2.5 moles * 2  = 5 moles of H

Mass of N = 92.0 g/46 g/mol = 2 moles * 1 = 2  moles of N

Dividing through by the lowest mole ratio;

1/1, 5/1, 2/1

1 : 5 : 2

Hence the empirical formula is;

CH5N2

Answer: [tex]5.60\times 10^{23}[/tex] molecules of carbon dioxide are produced

Explanation:

The balanced chemical equation is:

[tex]2C_2H_6(g)+7O_2 (g)\rightarrow 4CO2(g)+6H_2O(g)[/tex]

[tex]\text{Moles of water}=\frac{\text{given molecules}}{\text{Avogadros number}}=\frac{8.45\times 10^{23}}{6.023\\times 10^{23}}=1.40moles[/tex]

Accoding to stoichiometry:

6 moles of water are produced along with = 4 moles of carbon dioxide

Thus 1.40 moles of water are produced along with = [tex]\frac{4}{6}\times 1.40=0.93[/tex] moles of carbon dioxide

A sample of oxide iron weighing 2.40g was heated in a stream of hydrogen until it was completely converted to the metal. If the metal weighed 1.68g. What is the formula of the iron oxide? (Fe=56, O=16)

Answers

Answer:

Fe₂O₃

Explanation:

To solve this question we must find the moles of Iron in 1.68g. With the difference of the masses we can find the moles of oxygen. The formula will be obtained with the ratio of both amount of moles:

Moles Fe:

1.68g * (1mol / 56g)  =0.03moles

Moles O:

2.40g-1.68g = 0.72g * (1mol/16g) = 0.045moles

The ratio O/Fe is:

0.045moles / 0.03moles = 1.5 moles. this ratio is obtained if the formula is:

Fe₂O₃

Answers

Answer: [tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and are present in an aqueous state and represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

 The complete balanced ionic equation will be:

[tex]2Fe^{3+}(aq)+6Cl^-(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+6Cl^-(aq)+2Fe(s)[/tex]

 In this equation, [tex]Cl^-[/tex] are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be:

[tex]2Fe^{3+}(aq)+3Mg(s)\rightarrow 3Mg^{2+}(aq)+2Fe(s)[/tex]
