Complete question: Luisa likes to drink water from a plastic bottle. She knows the bottles were formed from synthetic polymers that were created in a chemical reaction. She also knows that synthetic materials can cause problems. Which statement explains the kind of problem that can develop from using synthetic materials such as plastics?
a) plastics have changed the way people use materials
b) plastics have made the lives of people easier
c) plastics have contributed to more pollution
d) plastics have made more work for people
Answer: The correct statement is plastics have contributed to more pollution. Option C.
Explanation:
Synthetic polymers are commonly called plastics. These are referred to as synthetic materials which can be softened by heat or pressure and then moulded into any desirable shape like the the plastic bottle Luisa drank from.
The raw materials for the manufacture of plastics are readily and cheaply available for the refinement of crude oil through series of chemical reactions. They are made by polymerization of monomers which are derived from petrochemicals.
Although they are used in producing materials used daily, it has contributed to more pollution over the years. POLLUTION is the release of chemicals or substances through man's activities, into the environment which causes harm to both man and the environment.
Plastics have contributed to more pollution because most plastics are non- biodegradable and cannot be broken down by microbial action into simple inorganic forms. Therefore, they cause severe land pollution problems since they are not easily disposable. Also is poses a major problem to the world supply of crude oil as it's limited. This is as a result of heavy dependence on crude oil which provides petrochemicals that is the bulk of the raw materials needed for making plastics.

Answer:
50 mL; 7
Explanation:
By looking at the graph, the boundary point where the solution turns from acidic to basic appears at approximately 50 mL.
Because this is a titration between a strong acid and strong base, the pH of the equivalence point is always 7 (aka neutral).

Answer:

Explanation:
The formula mass of a compound/molecule is calculated by summing the atomic masses of each individual atom in that compound or molecule.
According to this question, the gram-formula mass of CO2 is given as 44g i.e. by adding 12g of C and 2 × 16g of O. 3CO2 means that 3 moles of the same CO2 molecule.
To find the gram-formula mass of 3 moles of CO2, the following formula is used:
Since 1 mol of CO2 contains a formula mass of 44g
3 moles of CO2 (3CO2) will contain 3 × 44g = 132g of CO2.
A light bulb has a resistance of 96.8 Ω. What current flows through the bulb when it is connected to a 120 V source of electrical energy?
Answer:
I = 1.23 A
Explanation:
Given that,
The resistance of the lightbulb, R = 96.8 Ω
Voltage, V = 120 V
We need to find the current flows through the lightbulb. Let the current be I. We can use the ohm's law to find it i.e.
[tex]V=IR\\\\I=\dfrac{V}{R}\\\\I=\dfrac{120}{96.8}\\\\I=1.23\ A[/tex]
So, the current flows through the bulb is 1.23 A.

What method can be used to separate benzoic acid and potassium carbonate
Answer:
To separate the components, a water wash may be attempted to remove benzoic acid, but benzoic acid is not particularly water-soluble due to its nonpolar aromatic ring, and only small amounts would be extracted into the aqueous layer
The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method
Benzoic acid is slightly soluble in cold water but becomes more soluble as the temperature of water is increased. Water wash separation method is a methodology used for the selective removal of unwanted compounds in a mixture.
Separation method based on solubility water wash methodprecipitationThe separation of benzoic acid and potassium carbonate is based on the solubility differences between Benzoic acid and potassium carbonate when dissolved in a solvent ( water ) therefore the water wash separation method is the most effective method.
Hence we can conclude that The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method.

24g of methane were burned in an excess of air. What mass of water would be produced in the reaction assuming complete combustion?Use the information below to answer the question.
Answer:
54g of water
Explanation:
Based on the reaction, 1 mole of methane produce 2 moles of water.
To solve this question we must find the molar mass of methane in order to find the moles of methane added. With the moles of methane and the chemical equation we can find the moles of water produced and its mass:
Molar mass CH₄:
1C = 12g/mol*1
4H = 1g/mol*4
12g/mol + 4g/mol = 16g/mol
Moles methane:
24g CH₄ * (1mol / 16g) = 1.5 moles methane
Moles water:
1.5moles CH₄ * (2mol H₂O / 1mol CH₄) = 3.0moles H₂O
Molar mass water:
2H = 1g/mol*2
1O = 16g/mol*1
2g/mol + 16g/mol = 18g/mol
Mass water:
3.0moles H₂O * (18g / mol) =

Sn + 2 H2SO4 → SnSO4 + SO2 + 2 H2O If 219.65 grams of SnSO4 are produced, how many moles of H2SO4 were reacted?
Answer:
2.05moles
Explanation:
The balanced chemical equation in this question is as follows;
Sn + 2H2SO4 → SnSO4 + SO2 + 2H2O
Based on the above equation, 2 moles of H2SO4 reacted to produce 1 mole of SnSO4
However, the mass of SnSO4 produced is 219.65 grams. Using mole = mass/molar mass, we can find the number of moles of SnSO4 produced.
Molar mass of SnSO4 where Sn = 118.7, S = 32, O = 16
= 118.7 + 32 + 16(4)
= 150.7 + 64
= 214.7g/mol
mole = 219.65/214.7
mole = 1.023mol
Therefore, if 2 moles of H2SO4 reacted to produce 1 mole of SnSO4
1.023 mol of SnSO4 produced will cause: 1.023 × 2/1
= 2.046moles of H2SO4 to react.
At what point will potential energy be the highest? The object has a mass of 5 kg
Explanation:
Given that,
The mass of the object, m = 5 kg
We need to find the maximum potential energy. When the height of the object is maximum it will have the maximum potential energy.
The attached figure shows that the maximum height is 25 m. The formula for the potential energy is given by :
[tex]P=mgh\\\\P=5\times 9.8\times 25\\\\P=1225\ J[/tex]
So, when the height is 25 m, the object will have the highest potential energy.
