Consider the following diagram of a chemical reaction.
A series of four increasingly more complex chemical structures. The first diagram shows that when heat is applied to R single bond O single bond O single bond R, it creates 2 R single bond O with 1 electron dot. The next structure brings in more complex structures and other atoms, such as H and C. This process continues until the final molecule has a long chain of six starting with R O and ending with C with a single electron dot. There are four single side chains, 3 P h and 1 H.
What is the product that is formed in this reaction?
a polymer
a monomer
an alkyl halide
a carboxylic acid

A chemist working for Udensi industries wants to create a new ink for tattoos and cosmetics. Determine the theoretical yield of iron (ll) sulfide if the chemist uses 22.5 grams of iron ? Type of rxn : AD , SR, DR , D Type of calculation : mol to mol ; mol to mass ; mass to mols mass to mass Fe S8--> Fes
Answer:
35.36 g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
8Fe + S₈ —> 8FeS
Next, we shall determine the mass of Fe that reacted and the mass of FeS produced from the balanced equation. This can be obtained as follow:
Molar mass of Fe = 56 g/mol
Mass of Fe from the balanced equation = 8 × 56 = 448 g
Molar mass of FeS = 56 + 32 = 88 g/mol
Mass of FeS from the balanced equation = 8 × 88 = 704 g
SUMMARY:
From the balanced equation above,
448 g of Fe reacted to produce 704 g of FeS.
Finally, we shall determine the theoretical yield of FeS as follow:
From the balanced equation above,
448 g of Fe reacted to produce 704 g of FeS.
Therefore, 22.5 g of Fe will react to produce = (22.5 × 704)/448 = 35.36 g of FeS.
Thus, the theoretical yield of FeS is 35.36 g
17.5 mL of 0.1000M NaOH was required to neutralize 25.0 mL of HCl. What was the molarity of the HCl?
Answer: The molarity of [tex]HCl[/tex] is 0.07 M
Explanation:
According to the neutralization law,
[tex]n_1M_1V_1=n_2M_2V_2[/tex]
where,
[tex]n_1[/tex] = basicity [tex]HCl[/tex] = 1
[tex]M_1[/tex] = molarity of [tex]HCl[/tex] solution = ?
[tex]V_1[/tex] = volume of [tex]HCl[/tex] solution = 25.0 ml
[tex]n_2[/tex] = acidity of [tex]NaOH[/tex] = 1
[tex]M_1[/tex] = molarity of [tex]NaOH[/tex] solution = 0.1000 M
[tex]V_1[/tex] = volume of [tex]NaOH[/tex] solution = 17.5 ml
Putting in the values we get:
[tex]1\times M_1\times 25.0=1\times 0.1000\times 17.5[/tex]
[tex]M_1=0.07M[/tex]
Therefore, molarity of [tex]HCl[/tex] is 0.07 M

Answer:
446 mmHg
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 871 mmHg
Partial pressure of He (Pₐ) = 281 mmHg
Partial pressure of N₂ (P₆) = 144 mmHg
Partial pressure of O₂ (P꜀) =?
The partial pressure of O₂ can be obtained as follow:
Pₜ = Pₐ + P₆ + P꜀
871 = 281 + 144 + P꜀
871 = 425 + P꜀
Collect like terms
P꜀ = 871 – 425
P꜀ = 446 mmHg
Therefore, the partial pressure of O₂ in the mixture is 446 mmHg

Answer:
decomposition reaction.
Explanation:
It is a decomposition reaction as potassium chlorate compound breaks to form potassium chloride and oxygen. This reaction requires heat as source of energy to break down the compound so it is endothermic in nature.
Why are the relative and absolute ages of fossils important to scientists?
Answer Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. ... Relative dating places events or rocks in their chronologic sequence or order of occurrence. Absolute dating places events or rocks at a specific time.: Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.With absolute age dating, scientists determine the absolute age of a rock in millions of years before present rather than just the age of the rock relative to the rock units around it. This information helps geologists develop more precise geological history models for the rocks and regions they study.

What is the concentration of chlorine in ppm, in a 2.0L sample of pool water that contains 5.2mg of chlorine. How do I do this problem
Answer: 2.6 ppm
Explanation: ppm is parts per million, also 1:1000 000.
It means 1 mg in 1000 000 mg is same as 1 mg in 1000 g
Assume 2.0 litres weighs 2.0 kg = 2000 g
In one litre there is 2.6 mg Cl. You get a proportion 2.6 mg :1000 g
The concentration of chlorine is 2.6 ppm.
What is concentration?Concentration can be calculated in terms of Parts per million, or ppm, that is a measurement of dissolved solids in solution expressed as a ratio of the count of parts of solids/solute to one million parts of total volume.
The concentration can be calculated by using the formula:
C = m / v
where, C is concentration, m is mass and v is volume.
Calculation of concentration is shown as:
By using the formula, C = m / v
Put the values of m = 5.2 mg and v = 2 L in concentration formula.
C = 5.2 mg / 2 L
C = 2.6 ppm
Therefore, the concentration of solution will be 2.6 ppm.
