Gwar [14]

Answer:

\huge\boxed{\sf Single \ displacement \ reaction}

Explanation:

<h2><u>Displacement reaction:</u></h2>
  • A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.
<h3><u>Types:</u></h3>

There are 2 types:

<h3><u>1. Single displacement reaction:</u></h3>
  • If one element displaces 1 other element of a compound, it is called single displacement reaction.
  • <u>Example</u>:  CuSO_4 +Fe \longrightarrow \ FeSO_4 + Cu
  • Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.
<h3><u>2. Double displacement reaction:</u></h3>
  • If two elements in two compounds displace one another, it is called double displacement reaction.
  • <u>Example:</u> CuSO_4+NaOH \longrightarrow Cu(OH)_2 + Na_2SO_4
  • Here, Copper and sodium both displace each other.

You weigh a 24K gold chain and find that it weighs 400 grams. Determine home many moles of gold atoms you have
makkiz [27]

Answer:

                     2.03 moles of Gold

Explanation:

                     Gold is one of the most precious metal metal used in many applications and mainly as a jewellery. In terms of purity it is categorized in Karats. 24 Karat is considered the purest Gold (i.e. 100 % Gold) while other Karats (14, 18, 22 e.t.c) are alloys with other metals and gyms.

Data Given:

                 Mass of Gold  =  400 g

                 A.Mass of Gold  =  196.97 g.mol⁻¹

Calculate Moles of Gold as,

                              Moles  =  Mass ÷ M.Mass

Putting values,

                              Moles  =  400 g ÷ 196.97 g.mol⁻¹

                              Moles  =  2.03 moles of Gold

CH4 and CH3CH2CH3 have the lowest boiling points because they experience only \rm CH_4 and \rm CH_3CH_2CH_3 have the lowest boil
ki77a [65]

Answer:

Dispersion forces

Relative molecular mass

Explanation:

Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.
