If 3.5 moles of nitrogen monoxide (NO) react with 6.0 moles of oxygen gas (O2), how many moles of the product can be formed and
jasenka [17]

Answer: -

4.25 mol of O₂ left as excess.

3.5 mol of NO₂ formed.

Explanation: -

Number of moles of NO taken = 3.5

Number of moles of O₂ taken = 6.0

The balanced chemical equation for this reaction is

2 NO+ O₂ → 2 NO₂

From the equation we can see that

2 mol of NO react with 1 mol of O₂

3.5 mol of NO react with \frac{1 mol O2}{2 mol NO} x 3.5 mol NO

= 1.75 mol O₂

So Oxygen O₂ is in excess and NO is the limiting reagent.

Moles of O₂ left over = 6 - 1.75 =4.25 mol of O₂

From the balanced chemical equation we see

2 mol of NO gives 2 mol of NO₂

3.5 mol of NO gives\frac2 mol NO2}{2 mol NO} x 3.5 mol NO

= 3.5 mol of NO₂

What is the mass in grams of a single formula unit of silver chloride, AgCI? A) 4.21 x 1021 g B) 8.61 x 10258 C) 1.66 x 10-248 D
bekas [8.4K]

Answer: D) 2.38*10^-^2^2 g

Explanation: The question asks to convert formula unit to grams. It is a unit conversion problem.

1 mole equals to Avogadro number of formula units. So, to convert the given number of formula units to moles, we need to divide by the Avogadro number. After this, we do moles to grams conversion and for this the moles are multiplied by the molar mass of the compound. Molar mass of AgCl is 143.32 gram per mol.

1FormulaUnitAgCl(\frac{1mol}{6.022*10^2^3formulaUnits})(\frac{143.32g}{1mol})

= 2.38*10^-^2^2 g

So, the correct option is D) 2.38*10^-^2^2 g

4/10<br> Identify the equation below as molecular or ionic.<br> Mg2+(aq) + 20H-(aq) → Mg(OH)2(s)
Crank

Answer:

Ionic

Explanation:

Magnesium hydroxide is an ionic compound and its formula is Mg(OH)2. An ionic bond is formed between two atoms when one is electron deficient and the other one is electron sufficient.  

Here, Mg2+ is positively charged while OH- is negatively charged. Being oppositely charged strong ionic bonds are formed between these two elements.  

An ionic molecule has high boiling and melting point and is stronger than molecules formed by covalent bonds.
