Mass of moist aggregate sample as brought to the laboratory: 5,306 grams Mass of oven dried aggregate: 5,229 grams Mass of aggre
Lerok [7]

Answer:

a.   2.748

b. 68.91

c. 1.45%

d. 37.84%

Explanation:

To determine the:

a. The aggregate's bulk Saturated Surface Dry specific gravity

Given:

The mass of the moist aggregate sample is 5,229 g.

The mass of the oven-dried aggregate is 5,306 g.

The mass of the aggregate submerged in water is 5,229 g.

The mass of the Saturated Surface Dry aggregate is 3,298 g.

The aggregate's bulk SSD specific gravity =the dry weight ÷ ( the SSD weight - the submerged weight)

Given:

The mass of the oven-dried aggregate is 5,306 g.

The mass of the Saturated Surface Dry aggregate is 3,298 g.

The mass of the aggregate submerged in water is 5,229 g.

= 5,306 ÷ ( 3,298 - 5,229)

= 5,306 ÷ 1,931 = 2.748

b. The aggregate appearance specific gravity

the aggregate apparent specific gravity = the dry weight ÷ (the dry weight - the submerged weight)

Given:

The mass of the oven-dried aggregate is 5,306 g.

The mass of the aggregate submerged in water is 5,229 g

The aggregate apparent specific gravity = 5,306  ÷ (5,306 - 5,229)

The aggregate apparent specific gravity = 68.91

c. The moist content of stockpile aggregate

The moisture content of stockpile aggregate = ( the moist aggregate weight - the dry weight) ÷ the dry weight

Given:

The mass of the moist aggregate sample is 5,229 g.

The mass of the oven-dried aggregate is 5,306 g

The moisture content of stockpile aggregate = (5,229 - 5,306)  ÷ 5,306

The moisture content of stockpile aggregate = 0.0147 x 100% (when expressed in percentage) = 1.45%

d. Absorption

Absorption =  (mass of the Saturated Surface Dry aggregate - mass of the oven-dried aggregate)  ÷ mass of the oven-dried aggregate x 100%

Given:

The mass of the Saturated Surface Dry aggregate is 3,298 g

The mass of the oven-dried aggregate is 5,306 g.

Absorption =  (3,298  - 5,306)  ÷ 5,306  x 100% = 37.84%

1: Write balanced complete ionic equation for
monitta

Answer 1 : The balanced complete ionic equation will be,

NaOH(aq)+HNO_3(aq)\rightarrow H_2O(l)+NaNO_3(aq)

Na^+(aq)+OH^-(aq)+H^+(aq)+NO_3^-(aq)\rightarrow H_2O(l)+Na^+(aq)+NO_3^-(aq)

By removing the spectator ion in this equation, we get the balanced ionic equation.

OH^-(aq)+H^+(aq)\rightarrow H_2O(l)

Answer 2 : The balanced net ionic equation will be,

2Na_3PO_4(aq)+3NiCl_2(aq)\rightarrow Ni_3(PO_4)_2(s)+6NaCl(aq)

6Na^+(aq)+2PO_4^{3-}(aq)+3Ni^+(aq)+6Cl^-(aq)\rightarrow Ni_3(PO_4)_2(s)+6Na^+(aq)+6Cl^-(aq)

By removing the spectator ion in this equation, we get the balanced ionic equation.

2PO_4^{3-}(aq)+3Ni^+(aq)\rightarrow Ni_3(PO_4)_2(s)

Answer 3 : The balanced net ionic equation will be,

2Na_3PO_4(aq)+3NiCl_2(aq)\rightarrow Ni_3(PO_4)_2(s)+6NaCl(aq)

6Na^+(aq)+2PO_4^{3-}(aq)+3Ni^+(aq)+6Cl^-(aq)\rightarrow Ni_3(PO_4)_2(s)+6Na^+(aq)+6Cl^-(aq)

By removing the spectator ion in this equation, we get the balanced ionic equation.

2PO_4^{3-}(aq)+3Ni^+(aq)\rightarrow Ni_3(PO_4)_2(s)

Balanced equations : Balanced equations are the equations in which the number of individual elements present on the reactant side must be equal to the number of individual elements present on the product side.

Spectator ions : It is defined as the ions which do not participate in the chemical reaction. These ions exists in the same form on both the sides of the reaction.

Why would chloroethane have a lower boiling point than ethane?
Tom [10]
That is not true. Chloroethane has a greater boiling point than ethane.

This is due to the greater intermolecular attraction forces.

The greater electronegativity of Cl than C's, creates a stronger atraction of the electron cloud toward Cl, driving to the formation of permanent dipoles.

Then, in addition to the dispersion forces (present in the ethane and chlorometane) there are forces due to the attraction between the permanent dipoles, which cause a higher boiling point.
