Pani-rosa [81]3 years ago
8 0

Explanation:

A physical change is change that alters the physical properties of matter especially its form and state.

In many cases, the change is easily reversible.

Examples are change of state such as boiling, melting, freezing, condensation, sublimation e.t.c

A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes.

Examples are combustion, rusting , precipitation, milk souring.

  • Chemical changes are irreversible
  • Physical changes do not lead to the formation of new kinds of matter.
  • Most physical changes requires little energy.

How many sulfur atoms are present in 25.6 g of Al2(S2O3)3
IgorC [24]

Given the mass of Al_{2}(S_{2}O_{3})_{3}=25.6 g

The molar mass of Al_{2}(S_{2}O_{3})_{3}=390.35g/mol

Converting mass of Al_{2}(S_{2}O_{3})_{3}to moles:

25.6 g Al_{2}(S_{2}O_{3})_{3}*\frac{1molAl_{2}(S_{2}O_{3}}{390.35 gAl_{2}(S_{2}O_{3}} =0.0656molAl_{2}(S_{2}O_{3}

Converting mol Al_{2}(S_{2}O_{3})_{3}to mol S:

0.0656mol Al_{2}(S_{2}O_{3})_{3}*\frac{6molS}{1mol Al_{2}(S_{2}O_{3})_{3}}=0.3936 molS

Converting mol S to atoms of S using Avogadro's number:

1 mol = 6.022*10^{23}atoms

0.3936mol S *\frac{6.022*10^{23}atoms S}{1 mol S}=2.37*10^{23} S atoms

A balance and a graduated cylinder are used to determine the density of a liquid sample. The sample has a mass of 14.0 g and a v
mylen [45]

Answer:

Density = 7 g/mL

Explanation:

Given that,

Mass of a sample, m = 14 g

Volume of the sample, V = 2 mL

We need to find the density of the liquid sample. We know that the density of an object is given by :

d=\dfrac{m}{V}\\\\d=\dfrac{14\ g}{2\ mL}\\\\d=7\ g/mL

So, the density of the liquid sample is 7 g/mL.
