Part A: What changes does sugar undergo when heated in a spoon over the flame?
Select one:
A. A physical change, then a chemical change
B. Two physical changes
C. Two chemical changes
D. A chemical change, then a physical change
Part B: What evidence from the experiment and data table best supports your answer to Part A? Use information from the stimulus material and your knowledge of science to support your answer. In your answer, be sure to:
Desribe the evidence that supports your answer to Part A.
Provide your reasoning why that evidence supports your answer to Part A.
Answers
Answer:
part a=A. A physical change, then a chemical change
part b:evidence
without physical change any sorts of chemical change do not take place.
for example: when sugar is heated on spoon the physical change takes place in sugar .sugar starts to form liquid from solid.
Answer:
Part A. C would be your answer I think
Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar's atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.

What is the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml?
Answers
Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = molarity of stock [tex]CuSO_4[/tex] solution = 2.5 M
[tex]V_1[/tex] = volume of stock [tex]CuSO_4[/tex]solution = 5 ml
[tex]M_1[/tex] = molarity of diluted [tex]CuSO_4[/tex] solution = ?
[tex]V_1[/tex] = volume of diluted [tex]CuSO_4[/tex] solution = 750 ml
Putting in the values we get:
[tex]2.5\times 5=M_2\times 750[/tex]
[tex]M_2=0.017[/tex]
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M

how does a decrease in potential energy during a chemical rwaction relate to the temperature of the surroundings
Answers
Answer: If the potential energy of the reaction system decreases, then kinetic energy in the surroundings increases and the temperature of the surroundings rises
Explanation:
The decrease in the potential energy results in an increase in the temperature of the system and surroundings.
Mechanical energy has been described as the sum of the kinetic and the potential energy in the system. With the increase in the potential energy, there has been a decrease in the kinetic energy and vice versa.
The decrease in the potential energy results in an increase in the kinetic energy of the system. The kinetic energy has been termed as the energy of performing work. The rise in the kinetic energy results in an increase in the work done in the system and there has been an increase in the temperature of the system.
Thus, the decrease in the potential energy results in an increase in the temperature of the system and surroundings.

If 0.332 mol of zinc reacts with excess lead(IV) sulfate, how many grams of zinc sulfate will be produced in the reaction?
Answers
Answer:
53.6 g
Explanation:
Step 1: Write the balanced equation
2 Zn + Pb(SO₄)₂ ⇒ 2 ZnSO₄ + Pb
Step 2: Calculate the moles of ZnSO₄ produced from 0.332 moles of Zn
The molar ratio of Zn to ZnSO₄ is 2:2. The moles of ZnSO₄ produced are 2/2 × 0.0332 mol = 0.0332 mol.
Step 3: Calculate the mass corresponding to 0.332 moles of ZnSO₄
The molar mass of ZnSO₄ is 161.44 g/mol.
0.332 mol × 161.44 g/mol = 53.6 g

Which of the following statements best defines the actual yield of a reaction?
Select one:
a. The amount of product measured after a reaction
b. The ratio of measured yield over theoretical yield
c. The ratio of measured yield over stoichiometric yield
Answers
Answer: A) The amount of product measured after a reaction
A statement which best defines the actual yield of a reaction is "The amount of product measured after a reaction" Hence, Option (A) is correct
What is yield of any reaction?Yield of any chemical reaction gives idea about the amount of product that is produced by the chemical reaction between reactants.
Actual yield gives idea about the how much yield of any product will be produced in the given chemical reaction by using the stoichiometry of the reaction.
Therefore, A statement which best defines the actual yield of a reaction is "The amount of product measured after a reaction" Hence, Option (A) is correct

Why do not all rock types contain fossils?
Excessive heat and pressure can destroy fossils.
Fossils can only be created in certain places around the world.
Fossils cannot be created near volcanoes.
Fossils are too large to be found in igneous and metamorphic rocks.
Answers
Answer:
Igneous rocks form from molten rock, and rarely have fossils in them. Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions. Generally it is only sedimentary rocks that contain fossils.

Answers
Answer: Because They fall back to earth in the form of rain, sleet, hail, snow and dust. Most acid rain is caused by humans in the form of burning of fossil fuels. A very small percentage of acid rain is caused by natural causes such as volcanoes or wildfires.Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air.
