Cu + AgNO3 = Cu(NO3)2 +Ag

Answers

Answer 1

Answer: The problem is that you have to balance Cu + AgNO3 = Cu(NO3)2 + Ag

The first step is to identify all the elements and how many atoms of that element there are on either side of the equals sign.
When you do this you will get,

1 Cu 1
1 Ag 1
1 N 2
3 O 6

Next step is to make sure that all the elements are the same on both sides. This is mostly trial and error until you balance both sides.

The solution to the equation would be:

Cu + 2AgNO3 = Cu(NO3)2 + 2Ag

So now if you check your elements, you will get the following:

1 Cu 1
2 Ag 2
2 N 2
6 O 6

As you can see all the elements are equal on both sides, so the equation is balanced.

In which medium would sound move the fastest

Answers

Sound moves the fastest through a solid medium. Since the molecules within a solid are compactly or closely placed, so sound travels faster through it. It has already been experimentally proved that sound travels 17 times faster through a solid steel than through the air. This shows that sound can travel faster though a solid than through liquid or gas. Another way to prove that sound travels faster through solid is , if we place our ear in the railway line, then we can hear the sound of the train coming whereas the sound cannot be heard through the air.

True

Explanation:

The statement that patience, a popular card game in Mendeleev's time is also know as solitaire is very true. It was this card game that led to the discovery of the periodic table by Mendeleev in the 19th century.

In Europe, the game is called Patience. It is commonly called solitaire in in North America.
It involves the arrangement of a deck of cards.
The game inspired the invention of the periodic arrangement of elements by Russian Chemist, Dmitri Mendeleev.
Solitaire was popular card game around the time of this discovery.
