A metal is a solid material that usually has a hard surface. They are usually malleable, ductile, fusible, and shiny. They are also good conductors of electricity.

Nonmetals are materials that aren't metals, and have no similar properties with metals.

A metalloid is a material that has mixed properties of metals and nonmetals.

Why does secondary succession usually occur more rapidly than primary succession.

trapecia [35]

Secondary succession occurs more rapidly than primary because soil is already available so there is no need for any other species. Also, there might still be surviving species in the soil present like seeds, roots and other plant organs.

A sample of mass 6.814 grams is added to another sample weighing 0.08753 grams.

mylen [45]

Answer:

17.5609grams

Explanation:

According to the question, a sample of mass 6.814 grams is added to another sample weighing 0.08753 grams i.e.

= 6.814 + 0.08753

= 6.90153 grams

The result of this mixture i.e. 6.90153 grams is divided into three equal parts i.e.

= 6.90153 ÷ 3

= 2.30051 grams

This means that each equal part weighs 2.30051 grams

One of the yield (2.30051 grams) is multiplied by 7.6335 times i.e.

= 2.30051 × 7.6335

= 17.56094309

Hence, the final mass is 17.5609grams

Arsenic(III) sulfide sublimes readily, even below its melting point of 320 °C. The molecules of the vapor phase are found to eff

dezoksy [38]

The molecular formula : As₄S₆

<h3>Further explanation</h3>

Given

Rate of effusion of arsenic(III) sulfide = 0.28 times the rate of effusion of Ar atoms

Required

The molecular formula

Solution

Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or

the effusion rates of two gases = the square root of the inverse of their molar masses:

$\rm \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }$

$\rm M_1\times r_1^2=M_2\times r_2^2$

Input the value :

1 = Arsenic(III) sulfide

2 = Ar

MM Ar = 40 g/mol

0.28 = √(40/M₁)

M₁=40 : 0.28²

M₁=510 g/mol

The empirical formula of arsenic(III) sulfide = As₂S₃

(Empirical formula)n = molecular formula

( As₂S₃)n = 510 g/mol

(246.02 g/mol)n = 510 g/mol

n = 2

So the molecular formula : As₄S₆
