Answer:

21.6 grams

Explanation:

  • N₂ + O₂ → 2NO

First we <u>convert 10 g of N₂ into moles</u>, using its <em>molar mass</em>:

  • 10 g ÷ 28 g/mol = 0.36 mol N₂

Then we <u>convert 0.36 moles of N₂ into moles of NO</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 0.36 mol N₂ * \frac{2molNO}{1molN_2} = 0.72 mol NO

Finally we <u>convert 0.72 NO moles into grams</u>, using its <em>molar mass</em>:

  • 0.72 mol NO * 30 g/mol = 21.6 g

What is the correct answer ?
AlexFokin [52]

Answer:

Element with 6s subshell

Explanation:

Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.

This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.

Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.

Hence, the correct answer is "Element with 6s subshell".

A student calculated the molarity of a solution prepared by dissolving 0.730 mol of table sugar (sucrose, C12H22O11) in 1.8x10^3
lara31 [8.8K]

Answer: C= 0.406 M

Explanation:

V=1.8⋅10

3 mL=1.8L;

C=0.730mol

1.8 L=0.406 M

C= 1.8L

0.730mol =0.406M

The student made a mistake because he did not convert a unit of volume from milliliters to liters. After all, molarity is defined as the number of moles of solute per liter of solution.
