Which of these crystals is softest: P4, ZnS, CuCl, SiO2

lorasvet [3.4K]

I think the correct answer would be the first option. It is the solid phosphorus (P4) that will be the softest among these crystals. P4 is held by covalent bonding or sharing of electrons between atoms while ZnS, CuCl and SiO2 are being held by ionic bonding. Covalent bonding involves the overlapping of orbitals while ionic bonding has separation of the charges. Although covalent bonding is a strong type of bond, ionic bonding is much stronger as compared to the former. Being stronger, the compounds mentioned above with this type of bonding would tend to be harder than phosphorus which has covalent bonding only.

An unknown compound contains only C, H, and O. Combustion of 6.10 g of this compound produced 14.9 g of CO₂ and 6.10 g of H₂O. W

Tanzania [10]

Answer:

The answer to your question is C₃H₃O

Explanation:

Data

Combustion of a compound C, H, O

mass = 6.10 g

mass CO2 = 14.9 g

mass of water = 6.10 g

Reaction

Cx Hy Oz + O2 ⇒ CO2 + H2O

Process

1.- Calculate the moles of carbon

44 g of CO2 -------------- 12 g of carbon

14.9 g of CO2 ------------- x

x = (14.9 x 12) / 44

x = 4.06 g

12 g of C ------------------ 1 mol

4.06 g ------------------- x

x = (4.06 x 1) / 12

x = 0.34 moles

2.- Calculate the moles of hydrogen

18 g of water ------------- 1 g of hydrogen

6.10 g of water ---------- x

x = (6.10 x 1) / 18

x = 0.33 g

1 g of H ---------------- 1 mol of H

0.33 g ---------------- x

x = (0.33 x 1) / 1

x = 0.33 moles of H

3.- Calculate the mass of oxygen

mass of Oxygen = 6.10 - 4.06 - 0.33

= 1.71 g

16 g of O --------------- 1 mol of O

1.71 g of O ------------- x

x = (1.71 x 1) / 16

x = 0.11 moles

4.- Divide by the lowest number of moles

Carbon = 0.34 / 0.11 = 3

Hydrogen = 0.33 / 0.11 = 3

Oxygen = 0.11 /0.11 = 1

5.- Write the empirical formula

C₃H₃O

You drop a rock weighing 23.2 g into a graduated cylinder that contains 55 mL. The level

snow_lady [41]

Answer:

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 23.2 g

volume = final volume of water - initial volume of water

volume = 62 - 55 = 7 mL

We have

$density = \frac{23.2}{7} \\ = 3.314285$

We have the final answer as

Hope this helps you

How do dominant genes and recessive genes affect taste?

kherson [118]

Answer:

Explanation:

Because it is genetic, taste is thus inherited based on the allele combination, or “to taste, or not to taste”. The ability is highlighted here; the ability to taste PTC shows a dominant pattern of inheritance. A single copy of a tasting allele (T) conveys the ability to taste PTC.

65g of nitric acid are produced in a reaction. 2.5g of platinum are added to the reaction vessel at the start of the reaction to

AysviL [449]

Answer:

2.5 g of platinum

Explanation:

Recall that a catalyst is a specie added to a reaction system to increase the rate of reaction. A catalyst does not participate in the chemical reaction hence it remains unchanged at the end of the chemical reaction. A catalyst merely provides an alternative reaction pathway by lowering the activation energy of the reaction system. Hence a catalysed reaction usually proceeds faster with less energy requirement than the uncatalysed reaction.

Since the catalyst does not participate in the reactions and remains unchanged at the end of the reaction, the mass of platinum will remain the same (2.5g). The mass can only change if a specie participates in the chemical reaction. Hence the answer.
