Answer:

d = 0.5×10¹g/cm³

Explanation:

Given data:

Volume of material = 2 m³

Mass of material = 1×10⁴ Kg

Density of material = ?

Density:

Density is equal to the mass of substance divided by its volume.

Formula

d = m/v

Solution:

Volume of material = 2 m³

1 m³ = 1000000 cm³

2 ×10⁶cm³

Mass of material = 1×10⁴ Kg

1 Kg = 1000 g

1×10⁷ g

by putting values into density formula

d = 1×10⁷ g/2 ×10⁶cm³

d = 0.5×10⁷⁻⁶ g/cm³

d = 0.5×10¹g/cm³

Complete the paragraph about the formation of sodium phosphide.
Nadya [2.5K]
<h2>Let us complete it :</h2>

Explanation:

let us study about formation of sodium phosphide

Electrons are transferred from atoms of  sodium to atoms of phosphorous

The sodium atom looses electrons and the phosphorus atoms  

gains electrons .

C. This transfer makes the sodium atoms  acquire positive charge and phosphorous acquire negative charge .

As a result, the sodium and phosphorus atoms strongly  bond with

each other.

During the titration of a diluted vinegar sample with a sodium hydroxide solution, the volume of sodium hydroxide used was less
lapo4ka [179]

Answer:

B and D could be true

Explanation:

A volume of sodium hydroxide less than expected could occurs for two reasons:

The real concentration of sodium hydroxide was higher than expected or the amount of vinegar added was less than expected:

A. The sodium hydroxide solution had been allowed to stand exposed to the air for a long time prior to the titration.  FALSE. A long expose  to the air decreases concentration of the NaOH.

B. The volumetric flask used to prepare the diluted vinegar solution was rinsed with water prior to use.  TRUE. You add a less amount of vinegar doing you require less amount of NaOH than expected.

C. The burette used to deliver the sodium hydroxide solution was rinsed with water prior to use.  FALSE. Thus, you add a less amount of NaOH than expected. To explain the matter, you add more NaOH than expected.

D. The pipette used to deliver the vinegar solution was rinsed with water prior to use. TRUE. Again, you are adding a less amount of Vinegar than expected doing the necessary NaOH during titration less than expected
