2.What does it mean when a wave's amplitude increases?
A.Its frequency also increases. incorrect answer
B.It's moving through a denser medium. incorrect answer
C.Its wavelength gets longer. incorrect answer
D.It's carrying more energy.
Answers
Answer:
D. is the answer thankyiu
D. When a wave's amplitude increases, it means that the wave is carrying more energy.
What is amplitude?Amplitude refers to the maximum displacement of particles or the maximum height of a wave from its resting position.
As the amplitude increases, the wave becomes more intense, and it carries a greater amount of energy. This increase in energy does not affect the frequency or wavelength of the wave. The frequency of a wave refers to the number of complete oscillations it makes per unit of time, and the wavelength is the distance between two corresponding points on the wave.

A solution of Cuso, is labelled 1.743 M. How much Cuso, in grams, must be used to make
1.4957 liter of solution?
Select one:
O a. 416.1
Ob. 0.007301
O c. 166.6
Od. 129.2
Answers
Answer:
Option A. 416.1 g.
Explanation:
Data obtained from the question include the following:
Molarity = 1.743 M
Volume = 1.4957 L
Mass of CuSO4 =..?
Next, we shall determine mole of CuSO4 present in the solution.
This is illustrated below:
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole /Volume
With the above formula, we can obtain the mole CuSO4 present in the solution as follow:
Molarity = 1.743 M
Volume = 1.4957 L
Mole of CuSO4 =..?
Molarity = mole /Volume
1.743 = mole of CuSO4 /1.4957
Cross multiply
Mole of CuSO4 = 1.743 x 1.4957
Mole of CuSO4 = 2.607 moles
Finally, we shall convert 2.607 moles of CuSO4 to grams.
This can be obtained as follow:
Molar mass of CuSO4 = 63.55 + 32.06 + (16x4) = 159.61 g/m
Mole of CuSO4 = 2.607 moles
Mass of CuSO4 =..?
Mole = mass /molar mass
2.607 = mass of CuSO4 /159.61
Cross multiply
Mass of CuSO4 = 2.607 x 159.61
Mass of CuSO4 = 416.1 g
Therefore, 416.1 g of CuSO4 is needed to prepare the solution.

Explanation: Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.
The magnification of a light microscope can be found by multiplying the power of the eyepiece by the power of the objective lens. Calculate the magnifications of a microscope that has an 8X eyepiece, and 1OX and 40X objectives.
Answers
For the 10X objective:
Total magnification = Eyepiece magnification x Objective magnification
Total magnification = 8X x 10X
Total magnification = 80X
So the total magnification for the combination of the 8X eyepiece and the 10X objective is 80X.
For the 40X objective:
Total magnification = Eyepiece magnification x Objective magnification
Total magnification = 8X x 40X
Total magnification = 320X
So the total magnification for the combination of the 8X eyepiece and the 40X objective is 320X.
Answer: For 10X objective =80X
For 40X objectives =320 X
Explanation: The magnification of a light microscope can be computed by multiplying the power of the eyepiece by the power of the objective lens.
For the 10X objective = power of eyepiece × power of objective lens= 8X × 10X
= 80X
For the 40X objective = power of eyepiece × power of objective lens= 8X × 40X
= 320X

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Answers
Answer:
Explanation:
1- Cathode 2- copper electrolyte solution usually (CuSO4) 3- Cu half cell 4- bulb (when lighted, shows the current is flowing) 5- Zn half cell 6- Zn electrolyte solution 7- connecting wires 8- anode (Zn) 9-salt bridge
2- the copper-(Cu) electrode is the cathode and the zinc-(Zn) electrode will be the anode. This is because the cathode is negatively charged (while Cu is positively charged, so it attracts) and the anode is positively charged (while Zn will be negative)
3- the electrons flow from the anode, where oxidization takes place, to the cathode, where reduction reactions take place.
That's the best i can do. Hope it helps.
Answer:
Explanation:
• Label all parts (1–9), including the solutions in each beaker and the connecting tube.
1. Copper strip
2. Cu2+(aq) (copper electrolyte solution or copper nitrate)
3. Cathode compartment
4. Light bulb
5. Anode compartment
6. Zn2+ (aq) (zinc electrolyte solution or zinc nitrate)
7. The connecting wires or the external circuit
8. Zinc strip
9. Salt bridge
• Label which cell is the cathode and which cell is the anode. Include the charge on each strip.
The copper strip is the cathode and the zinc strip is the anode. The anode is positively charged and the cathode is negatively charged. This is because the cathode attracts a positive charge and the anode attracts a negative charge.
• Show, or describe in detail, the flow of electrons.
The atoms from the zinc strip are oxidized into zinc ions, (the anode is where oxidation occurs). The electrons in the anode then travel through the wire to the copper strip. The electrons then merge with the copper ions in the solution creating copper metal (the cathode is where reduction occurs).
• Describe what type of electrochemical cell is pictured. Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.
This is a voltaic or galvanic cell. It works by using spontaneous oxidation-reduction reaction to generate electricity.

Answers
Answer:
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Reactants are the starting materials, while products are the end result of the reaction. All chemical reactions are accompanied by a change in entropy.
In general, chemical reactions can be classified as either redox reactions or non-redox reactions. In redox reactions, there is a transfer of electrons between reactants. In non-redox reactions, there is no electron transfer. All exothermic reactions are redox reactions, while endothermic reactions may be either redox or non-redox.
