What is the purpose of an ionic bond?
Yuri [45]

Answer:

Ionic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding

What impact would a sudden increase in the price of wood have on producers and consumer? How might each group respond to the cha
Lisa [10]
The law of supply states, things remaining equal, an increase in price results in an increase in quantity supplied. The direct relation which is between the price and quantity. 

Therefore, when the price of wood increases, then the producers increases the quantity which is produced as they are willing to sell more at a higher price. Each group might respond to the change in price in that, the law of demand states that all things are equal.
A decrease in a quantity leads to an increase in price which is demanded. The existence in an inverse relation which is between price and quantity.
When the demand for good increases the consumer demand decreases.

The following redox reaction is conducted with [Al3+] = 0.12 M and [Mn2+] = 1.5 M.
Ronch [10]

Answer:

0.47V

Explanation:

2 Al(s) + 3 Mn2+(aq) → 2 Al3+(aq) + 3 Mn(s)

n= 6 ( six moles of electrons were transferred)

Q= [Red]/[Ox] but [Red]= 1.5M, [Ox] = 0.12 M

Q= 1.5/0.12= 12.5

From Nernst equation:

E= E°cell- 0.0592/n log Q

E°cell= 0.48 V

E= 0.48 - 0.0592/6 log (12.5)

E= 0.47V

If the input force applied to one end of a first-class lever is 8 N, and the fulcrum is located 6 m away from the input force bu
MatroZZZ [7]

Answer:

16 N

Explanation:

The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.

We have,

Input force = 8 N

Input arm distance = 6 m

Output arm distance = 3 m

We need to find the resulting output force. So,

\dfrac{F_o}{8}=\dfrac{6}{3}\\\\F_o=16\ N

So, the resulting output force is 16 N.
