a chemical company makes pure silver by reacting silver nitrate with Zinc. the company needs to make 800 grams of pure silver fo

shutvik [7]

The reaction between zinc and silver nitrate is

$Zn + 2 AgNO3 \rightarrow Zn(NO3)2 + 2 Ag$

Moles of Zn = m /M = 599 /65 = 9.2 mol

Moles of AgNO3 = m /M = 1500 /169 = 8.87 mol

Silver nitrate is reacting completely to give silver

Thus, moles of Silver nitrate is equivalent to silver = 8.87

For mass of silver produced

m /M = 8.87 = m /107

m = 949.24 g

Hence, the given quantity of reactants are sufficient to produce 800 g of silver as the amount of silver produced is 949.24 g

Effects of a thunderstorm in order

Ede4ka [16]

Answer:

Rainfall from thunderstorms causes flash flooding, killing more people each year than hurricanes, tornadoes or lightning. Lightning is responsible for many fires around the world each year, and cause fatalities. Hail up to the size of softballs damages cars and windows, and kills wildlife caught out in the open.

The skeletal structure in line-angle (line-bond) mode of 2,3,3,5-tetramethylhexane is shown. Identify the number of hydrogen ato

Kruka [31]

Answer:

There are 22 hydrogen in 2,3,3,5-tetramethylhexane (C10H22)

From the left to the right of the skeletal structure:

1st Main Carbon = 3 hydrogen

2nd Main Carbon = 1 hydrogen

1st Branch Carbon = 3 hydrogen

3rd Main Carbon = 2 hydrogen

2nd Branch Carbon = 3 hydrogen

3rd Branch Carbon = 3 hydrogen

4th Main Carbon = 0 hydrogen

4th Branch Carbon = 3 hydrogen

5th Main Carbon = 1 hydrogen

6th Main Carbon = 3 hydrogen

Total = 22 hydrogen

Explanation:

This is the skeletal formula for 2,3,3,5-tetramethylhexane - the 2D chemical structure. It is an organic compound. The carbon atoms in the structure are known as the carbon backbone. The hydrogen atoms are linked to the carbon backbone. This provides each carbon atom with four bonds.

Put these steps of solar

kupik [55]

Answer:

3-1-5-2-4

Explanation:

scientists believe that the solar system was formed when some star had its explosion and due to its explosion there were waves generated in the space thus squeezing clouds and dust eventually gravity pulling everything together forming solar nebula. the clouds spin faster and faster thus making it into a thin disk and also the cloud becoming hotter and dense thus forming stars.
