What is one effect of the uneven heating of Earth caused by the Sun? (Answer with a 5 sentence paragraph)

Chemistry
1 answer:
Papessa [141]3 years ago
7 0

Answer:

Albedo

Explanation:

Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather. The cause of this is the reflectiveness of the surface of the Earth at that point (the albedo) and the angle that the sun's rays strike it at. A field covered with snow and ice is going to be much more reflective than a black top asphalt parking lot. As such the parking lot absorbs much more shortwave radiation from the sun and gets much warmer.

The work done depends upon the --------------applied and the -------------- produced​
Deffense [45]

Answer:

The work done depends upon the <u> Force</u> applied and <u>Displacement</u> produced.

Explanation:

Definition: Work is said to be on a body only if a force acting on it causes a displacement in its direction .

In other words we can say it is the product of force and displacement

Formula:

Work = Force\times Displacement\ cos \theta

Unit:

The unit of work is Joule.

So, work depends on the force applied and the displacement caused by the applied force.

If force is applied and there is no displacement, then work is 0 .

Example: Pushing a wall does no work.

Work is positive if force applied and displacement is in same direction.

Work is negative if force applied and displacement is in opposite direction.

Can chopper be changed to gold? Explain​
Firlakuza [10]

Answer:

A team of Chinese researchers have turned cheap copper into a new material “almost identical” to gold, according to a study published in peer-reviewed journal Science Advances on Saturday. The fast-moving ionized particles blasted copper atoms off the target.

Number of Mg(OH)2 formula units in 7.40 moles of Mg(OH)2.
-Dominant- [34]
The answer is 4.45 × 10²⁴ units.

To calculate this, we will use Avogadro's number which is the number of units (atoms, molecules) in 1 mole of substance:
6.02 × 10²³ units per 1 mole

So, we need a proportion:
If 6.02 × 10²³ units are in 1 mole, how many units will be in 7.40 moles:
6.02 × 10²³ units : 1 mole = x : 7.40 moles

After crossing the products:
1 mole * x =  7.40 moles * 6.02 × 10²³ units
x = 7.40 * 6.02 × 10²³ units
x = 44.5 × 10²³ units = 4.45× 10²⁴ unit

2C2H2(g)+5O2(g)=4CO2(g)+2H2O(g)
balandron [24]

The volume of ethyne, C₂H₂ required to produce 12 moles of CO₂ assuming the reaction is at STP is 134.4 L

<h3>Balanced equation</h3>

2C₂H₂(g) + 5O₂(g) --> 4CO₂(g) + 2H₂O(g)

From the balanced equation above,

4 moles of CO₂ were produced by 2 moles of C₂H₂

<h3>How to determine the mole of C₂H₂ needed to produce 12 moles of CO₂</h3>

From the balanced equation above,

4 moles of CO₂ were produced by 2 moles of C₂H₂

Therefore,

12 moles of CO₂ will be produce by = (12 × 2) / 4 = 6 moles of C₂H₂

<h3>How to determine the volume (in L) of C₂H₂ needed at STP</h3>

At standard temperature and pressure (STP),

1 mole of C₂H₂ = 22.4 L

Therefore,

6 moles of C₂H₂ = 6 × 22.4

6 moles of C₂H₂ = 134.4 L

Thus, we can conclude that the volume of C₂H₂ needed for the reaction at STP is 134.4 L
