Answer:directly to the right
Explanation:
Atomic size increases from left to right
Explanation:
Group 16 elements are oxygen family elements also called as chalcogens.This name is given for the their ore forming abilities. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium.
Group 16 have six electron in the outermost principal energy level or the valence shell and their general electronic configuration is ns2 and np4.
Answer: Chemistry is the study of matter and the changes it undergoes.
An example of chemistry being used in the real world is how an ECG works. Chemistry is also sometimes considered the "central science". I hope this answer helped!! :)
Answer:
2.08 * 
Explanation:
Avagadros number times the # of moles.
Based on the equation of the reaction, nitrogen is the limiting reagent while hydrogen is the excess reagent.
<h3>What is the mole ratio of hydrogen to nitrogen in the formation of ammonia?</h3>
Hydrogen and nitrogen combines to form ammonia ina mole ratio of 3 : 1 as shown by the equation of the reaction below:
The number of moles of the reactants in 14g of Nitrogen gas and 8.0g of hydrogen is calculated as follows:
Molar mass of N_{2} = 14.0 g
Molar mass of H_{2} = 2.0 g
Moles of N_{2} = 14/14.0 = 1 mole
Moles of H_{2} = 8/2.0 = 4 moles
Based on the data above:
- The limiting reagent is nitrogen gas as it will be used up while hydrogen will be left over.
- The moles of nitrogen is 1 mole
- Hydrogen is the excess reagent and 1 mole will be left over
- 3 moles of hydrogen will react with 1 mole of the nitrogen gas
- mass of 3 moles of hydrogen is 3 × 2.0 g = 6.0g
Therefore, the limiting reagent is nitrogen while hydrogen is the excess reagent.
