2Na + Cl2 → 2NaCI<br> How many grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl.?
Mademuasel [1]

54.936 grams of NaCl will be produced from 33.0 g of Na and 34.0 g of Cl.

Explanation:

Data given:

mass of Na = 33 grams

mass of Cl_{2} = 24 grams

atomic mass of Na = 23 grams/moles

atomic mass of Cl = 70 grams/mole

mass of NaCl formed =?

atomic mass of NaCl = 58.44 gram/mole

balanced chemical reaction:

2Na + Cl_{2} ⇒ 2NaCl

number of moles = \frac{mass}{atomic mass}

putting the values in the equation:

number of moles of Na = \frac{23}{33}

                                     = 0.69 moles

number of moles of chlorine gas = \frac{34}{71}

                                                        = 0.47 moles

limiting reagent is chlorine gas in the reaction

from the balanced chemical reaction:

1 mole of chlorine gas reacts to form 2 moles of NaCl

then 0.47 moles of chlorine gas will form x moles

\frac{2}{1} = \frac{x}{0.47}

x = 0.94 moles of NaCl is formed.

mass = atomic mass x number of moles

mass = 58.44 x 0.94

         = 54.936 grams of NaCl is produced.

A bond in which one atom contributes both bonding electrons to a covalentbond
yKpoI14uk [10]
<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>
  • A chemical bond is a force of attraction between two or more atoms of elements.
  • Covalent bond is a type of chemical bond that occurs between non-metal atoms.
  • It occurs as a result of sharing of electrons between the non-metal atoms.
  • Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
  • When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.

Air in a closed cylinder is heated from 15°C to 36°C. If the initial pressure is 1000 torr, determine what is the final pressure
Bingel [31]

Answer:

1072 torr

Explanation:

To answer this problem we can use <em>Gay-Lussac's law</em>, which states:

  • P₁T₂=P₂T₁

Now we convert the given temperatures into K:

  • T₁ = 15°C ⇒ 15+273.16 = 288.16 K
  • T₂ = 36°C ⇒ 36+273.16 = 309.16 K

We <u>input the data</u>:

  • 1000 torr * 309.16 K = P₂ * 288.16 K

And <u>solve for P₂</u>:

  • P₂ = 1072 torr
