Which metal reacts spontaneously with NiCl2(aq)?
A) Au(s)
B) Cu(s)
C) Sn(s)
D) Zn(s)
Answer:
THE answer IS B)cu(s)
Explanation:
HOPE ITS HELP
The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.
What is reactivity series?Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.
According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au
So, zinc will replace the nickel atom from NiCl₂ solution.
Hence option (D) is correct.

Why does the border between light and dark on the Moon change location?
We only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.
What is solar system?Solar system is defined as the Sun's orbiting objects are confined by gravity to one system. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system.
The terminator is the line on the moon that divides day from night. The moon's surface is in a twilight state along the terminator line, which is where the twilight zone is frequently referred to as. The sun is either rising or setting on the moon along this line.
Thus, we only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.

Explain why higher temperature in a substance does not mean the substance has more thermal energy?
Answer:
Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures.
Explanation:
If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature is measured with a thermometer.

A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42
Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42
Newtons. With what force does the scale push back up against her feet?
Answer:
The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it have taken? (In seconds)
Answer:
36
Explanation:
It would have taken 36 s for John to cover the distance.
Average speed is defined as the total distance travelled divided by the total time taken.
Average speed = Total distance / total timeTo obtain the answer to the question, we'll begin by calculating the time taken to cover the distance (3150 m) in each case.
Case 1:Average speed = 350 m/min
Total Distance = 3150 m
Time 1 =?Average speed = Total distance / total time
350 = 3150 / Time 1
Cross multiply
350 × Time 1 = 3150
Divide both side by 350
Time 1 = 3150 / 350
Time 1 = 9 mins
Multiply by 60 to express in seconds
Time 1 = 9 × 60
Time 1 = 540 sCase 2:Average speed = 375 m/min
Total Distance = 3150 m
Time 2 =?Average speed = Total distance / total time
375 = 3150 / Time 2
Cross multiply
375 × Time 2 = 3150
Divide both side by 375
Time 2 = 3150 / 375
Time 2 = 8.4 mins
Multiply by 60 to express in seconds
Time 2 = 8.4 × 60
Time 2 = 504 sFinally, we shall determine how much sooner it would have taken John to travel at 375 m/min. This can be obtained as follow:
Time 1 = 540 s
Time 2 = 504 s
Difference in Time =?Difference = Time 1 – Time 2
Difference in time = 540 – 504
Difference in time = 36 sTherefore, it would have taken John 36 s if he had travelled at an average speed of 375 m/min.

ugh help i have to write a 1 -page essay for my honors sci class
and i have no clue how to its over Photosynthesis but we have to have answer to these questions in it to :(What is photosynthesis? What role does the Sun play in the interaction of energy during photosynthesis? What forms of energy conversion occur? What form does the chemical energy take? What gas do plants release as a result?): so i have no clue how to write it .?.?.?.?.?.?
.
Answer:
1 . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
2. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
3.Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.
4 . Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.
