Answer:
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Explanation:
First you see which side has the most elements. Which is Cu(NO3)2 + Ag. But, both sides have the same elements? But, on the reactants side, there is 2 of NO3. On the products side there is only one.
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 1 NO3 = 2
Ag = 1 Ag = 1
They are all equal, except for NO3. So on the reactants side, you add a two to make it even.
2AgNO3 + Cu = Cu(NO3)2 + Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 1
Now, the NO3 is equal, But the Ag isn't. But, you can add a 2 on the <u>products</u> side so the whole equation becomes equal.
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Reactants: Products:
Cu = 1 Cu = 1
NO3 = 2 NO3 = 2
Ag = 2 Ag = 2
Answer:
A: Object A will move in the up direction. But not object B
Explanation:
It will move in the up direction because object A has an unbalanced force. For the up direction there, it is 6 newtons and for the bottom direction, it is 2 newtons. For the right and left direction, both of them are 3 newtons. So object A will move in the up direction because it has the most newtons(which is 6).
For Object B, it is unbalanced too. But object B will move to the right because it is 2 newtons there and there is one newton on the left. Furthermore, the up and down directions are 3 newtons. So they are balanced and will cancel out. Therefore, object A will move in the right direction because it has the most newtons(which is 3).
So the final answer is object A. Hope it helped!
The scientific notation of 420,000 is : 4.2 x 10 ^ 5
Answer:
In differential calculus, related rates problems involve finding a rate at which a quantity changes by relating that quantity to other quantities whose rates of change are known. The rate of change is usually with respect to time.
