Study this equation carefully. What classification should this reaction have? Cu + 2AgNO3 Cu(NO3)2 + 2Ag synthesis decomposition single replacement double displacement neutralization
Answers
Answer;
-Single replacement
Explanation;
The reaction;
Cu(s) + 2AgNO3= Cu(NO3)2 + 2Ag , is an example of a single replacement reaction.
-It is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
In the above reaction copper(Cu) takes the place of silver(Ag) in the salt AgNO3 to form Copper (ii) nitrate (CuNO3) and silver metal (Ag).
- Another example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Answer:
single replacement

The correct answer to the question is - Deposition i.e the process by which a gas changes to a solid is called deposition.
EXPLANATION:
There are various thermal processes of state or phase change in which matter in one state is converted into matter in another state.
Deposition is the type of thermodynamic process of state or phase change in which a gaseous substance is directly converted into corresponding solid substance without entering into liquid phase.
During this process, the loss of thermal energy from gas is very fast. Hence, the gas directly enters solid phase without undergoing into liquid phase.
This process is just the opposite process of sublimation where a solid is converted into gas directly. That's why this process is also known as desublimation.
For instance, conversion of water vapor into ice.

The law of conservation of momentum states that the total momentum of a closed system does not change. This means that when two objects collide the total momentum of the objects before the collision is the same as the total momentum of the objects after the collision.
Total momentum meansthe momentum of object 1 plus the momentum of object 2.Object 1 might not have the same momentum before and afterthe collisionbut the amount of momentum object 1 gains from the collisionis the same as the amount of momentum object 2 losesso the total momentum remains the same whether the collision is elastic or inelastic.The total momentum is also the same before and after an explosion.

Yep. Just like radio waves, X-rays, and orange light waves.
Gamma rays are exactly the same thing as those, only shorter.

Answer:
The ball will go over the net when she's standing 2 feet away from the net, but not at 4 ft from the net
Explanation:
Suppose then when the player is 2ft from the net, we can plug in x = 2:
As 8 feet > 7 ft 4 in, the ball will go over the net
If the player moves back so that she's 4 feet from the net, plug in x = 4:
As 7 ft < 7 ft 4 in, this time the ball will NOT go over the net
Final answer:
The function models the path of a volleyball when the player is 2 feet from the net and will the ball go over the net at different distances.
Explanation:
The function f(x) = -0.25(x-2)^2 + 8 models the path of a volleyball when the player is 2 feet from the net. To determine if the ball will go over the net, we need to compare the height of the ball's path with the height of the net.
First, let's convert the height of the net to feet. The height, 7 ft 4 in, is equivalent to 7.33 feet. Now, substitute x = 2 into the function to find the height of the ball when the player is 2 feet from the net. f(2) = -0.25(2-2)^2 + 8 = 8 ft.
The ball will go over the net because the height of the ball, 8 feet, is greater than the height of the net, 7.33 feet.
If the player moves back so she is 4 feet from the net, substitute x = 4 into the function: f(4) = -0.25(4-2)^2 + 8 = 10 ft. The ball would still go over the net, as the height of the ball, 10 feet, is greater than the net's height.
