How do magnetic stripes show the history of Earth's magnetic field?
A. As you move away from an ocean ridge, the rocks get older.
B. As you move away from a coast, the rocks get younger.
C. As you move down through the seafloor, rocks get older.
D. As you move eastward along a continent, rocks get older.
Answers
The way that magnetic stripes show the history of the Earth's magnetic field is A. As you move away from an ocean ridge, the rocks get older.
What do magnetic strips show of Earth's history ?By looking at how our planet's magnetic field changes throughout time, scientists may estimate the age of the seafloor. A geomagnetic reversal is the periodic reversal of the currents in the liquid core that generate the Earth's magnetic field. Throughout Earth's history, this has occurred frequently.
When researchers examined the seafloor's magnetic characteristics, they found normal and reversed magnetic stripes of varying widths. These magnetic patterns are symmetrical on both sides and parallel to the mid-ocean ridges.
Away from midocean ridges, they observed that the age of the bottom became progressively older.

B) Generating electricity from a coal-fired power plant
C) Generating electricity from a nuclear power plant
D) Generating electricity from a solar panel system
Answers
Hello!
The answer to this question is: D) Generating electricity from a solar panel system.Thank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!
Have an amazing day.
The energy transformation which produces electricity and is least likely to
negatively impact the environment is generating electricity from a solar
panel system.
Generating electricity from solar panel involves the use of solar energy from
the sun to generate electricity . This type of energy doesn't emit any type of
harmful radiation or release toxic compounds into the atmosphere which
makes it the least likely to negatively impact the environment.
Other options emit any type of harmful radiation or release toxic compounds
into the atmosphere which makes option D the most appropriate.

Calculate the number of milliliters of 0.440 M KOH required to precipitate all of the Fe2+ ions in 187 mL of 0.692 M FeSO4 solution as Fe(OH)2. The equation for the reaction is: FeSO4(aq) + 2KOH(aq) Fe(OH)2(s) + K2SO4(aq)
Answers
Answer:
588.2 mL
Explanation:
FeSO₄(aq) + 2KOH(aq) → Fe(OH)₂(s) + K₂SO₄(aq)First we calculate how many Fe⁺² moles reacted, using the given concentration and volume of FeSO₄ solution (the number of FeSO₄ moles is equal to the number of Fe⁺² moles):
moles = molarity * volume187 mL * 0.692 M = 129.404 mmol Fe⁺²Then we convert Fe⁺² moles to KOH moles, using the stoichiometric ratios:
129.404 mmol Fe⁺² * [tex]\frac{2mmolKOH}{1mmolFeSO_4}[/tex] = 258.808 mmol KOHFinally we calculate the required volume of KOH solution, using the given concentration and the calculated moles:
volume = moles / molarity258.808 mmol KOH / 0.440 M = 588.2 mLI GIVE BRAINLIEST IF YOU ANSWER!

How many moles of carbon are there in 5 g of carbon?
Answers
Answer:
0.416666667
Explanation:
number of moles= mass of sample ÷ molar mass
=5÷12
=0.41666667
The number of moles of carbon are there in 5 gram of carbon is 0.41 moles.
How do we calculate moles from mass?Moles of any substance will be calculated by using the mass by following the below equation:
n = W/M, where
W = given mass of carbon = 5g
M = molar mass of carbon = 12g/mol
On putting values, we get
n = 5 / 12 = 0.41 moles
Hence required moles of carbon is 0.41 moles.

Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earth’s spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle. Large poster board Markers, crayons, or colored pencils Scissors Glue or tape Student Guide (continued) Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.

C. The sum of the voltages of the half-reactions is negative.
D. The sum of the voltages of the half-reactions is positive.
Answers
Answer:
D. The sum of the voltages of the half reactions is positive.
Explanation:
It's correct on apeex
The statement, that describes the redox conditions will produce a spontaneous reaction is "the sum of the voltages of the half-reactions is positive."
What is spontaneous reaction?A spontaneous reaction is one that favors the creation of products under the conditions of the reaction. It can move in a specific direction without being propelled by an external source of energy. If the standard electrode potential for the redox reaction is positive, the reaction is spontaneous.
If [tex]E^{0}[/tex] (redox reaction) is positive, the reaction will move onward (spontaneous). The redox conditions will cause a spontaneous reaction, and the sum of the half-reaction voltages is positive. Hence the correct option is D.
