This is an incomplete question, the complete question is given below.

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.  Match the reactants with the products.

copper sulfate + oxygen

copper oxide

zinc sulfate + copper

aluminum chloride + copper

copper + water

copper sulfate + zinc  →

aluminum + copper chloride  →

copper oxide + hydrogen  →

copper + oxygen  →

Answer :

Copper sulfate + Zinc → Zinc sulfate + copper

Aluminium + Copper chloride → Aluminium chloride + copper

Copper oxide + Hydrogen → Copper + Water

Copper + Oxygen → Copper oxide

Explanation :

As we know that chemical reaction is a reaction in which two or more than two substances or reactants are reacted to give two or more than two different products.

According to the question:

  • Copper sulfate + Zinc → Zinc sulfate + copper

This reaction is a single replacement reaction in which zinc is more reactive than copper and zinc displaces copper from its salt to give products.

  • Aluminium + Copper chloride → Aluminium chloride + Copper

This reaction is a single replacement reaction in which aluminium is a more reactive element than copper and aluminium displaces copper from its salt to give products.

  • Copper oxide + Hydrogen → Copper + water

This reaction is a single replacement reaction in which hydrogen displaces less reactive metals from their oxide to form water and the metal.

  • Copper + Oxygen → Copper oxide

This reaction is a synthesis reaction in which two different atoms or molecules combine to form single compound.

Consider three scenarios in which a particular box moves downward under the pull of gravity :
luda_lava [24]

Answer:

1. True  WA > WB > WC

Explanation:

In this exercise they give work for several different configurations and ask that we show the relationship between them, the best way to do this is to calculate each work separately.

A) Work is the product of force by distance and the cosine of the angle between them

    WA = W h cos 0

   WA = mg h

B) On a ramp without rubbing

     Sin30 = h / L

     L = h / sin 30

     WB = F d cos θ  

     WB = F L cos 30

     WB = mf (h / sin30) cos 30

     WB = mg h ctan 30

C) Ramp with rubbing

    W sin 30 - fr = ma

   N- Wcos30 = 0

   W sin 30 - μ W cos 30 = ma

    F = W (sin30 - μ cos30)

   WC = mg (sin30 - μ cos30) h / sin30

   Wc = mg (1 - μ ctan30) h

When we review the affirmation it is the work where there is rubbing is the smallest and the work where it comes in free fall at the maximum

Let's review the claims

1. True The work of gravity is the greatest and the work where there is friction is the least

2 False. The job where there is friction is the least

3 False work with rubbing is the least

4 False work with rubbing is the least

To Mr. H's disgust, a 450-g black crow is raiding the recently-filled bird feeder. As Mr. H runs out the back door with his broo
bagirrra123 [75]

Answer:

Actually it's 2.50 m/s, sorry

Explanation:

It is solved by using momentum conservation equation

combined mass of crow and feeder = 450+670=1120 gm

let the recoil speed of feeder be v m/s

Then applying momentum conservation we get;

1120×1.5 = 670×v

v= 2.50 m/s

the speed at which the feeder initially recoils backwards = 2.50 m/s
