Answer:

A mixture is formed when two or more substances are mixed physically and not chemically combined. involves smaller particles in a mixture passing through holes, whilst the larger particles remain behind in the sieve. Sieves of different grades can be used to separate out particles of different sizes.

Answer:

A mixture is formed when two or more substances combine together so there is no chemical reaction between them

Explanation:

Since the constituents of a mixture are not chemically combined, so they can easily be separated from each other by certain physical methods.

Look at the Lewis structures of the following molecules and predict their 3-D shapes according to the VSEPR theory. Oxygen dichl
Snowcat [4.5K]

Oxygen dichloride molecule consists  of an oxygen atom and two chlorine atoms. According to the VSEPR theory, the 3-D shape of the compound is bent.

There are 6 valence electrons in the oxygen atom and each chlorine atom has 1 valence electrons. Therefore, there are 8 valence electrons or 4 pairs of valence electrons.

According to VSEPR theory, due repulsion between 4 pairs of valence electrons, bond angle between two O-Cl bonds becomes 110 degrees and the shape of the molecule of the compound becomes bent.

Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or
Ahat [919]

Answer :

Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.

Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.

Rules for Oxidation Numbers are :

  • The oxidation number of a free element is always zero.
  • The oxidation number of a monatomic ion equals the charge of the ion.
  • The oxidation number of  Hydrogen (H)  is +1, but it is -1 in when combined with less electronegative elements.
  • The oxidation number of  oxygen (O)  in compounds is usually -2.
  • The oxidation number of a Group 17 element in a binary compound is -1.
  • The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
  • The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

Now we have to determine the oxidation state of the elements in the compound.

(a) H_2SO_4

Let the oxidation state of 'S' be, 'x'

2(+1)+x+4(-2)=0\\\\x=+6

Hence, the oxidation state of 'S' is, (+6)

(b) Ca(OH)_2

Let the oxidation state of 'Ca' be, 'x'

x+2(-2+1)=0\\\\x=+2

Hence, the oxidation state of 'Ca' is, (+2)

(c) BrOH

Let the oxidation state of 'Br' be, 'x'

x+(-2)+1=0\\\\x=+1

Hence, the oxidation state of 'Br' is, (+1)

(d) ClNO_2

Let the oxidation state of 'N' be, 'x'

-1+x+2(-2)=0\\\\x=+5

Hence, the oxidation state of 'N' is, (+5)

(e) TiCl_4

Let the oxidation state of 'Ti' be, 'x'

x+4(-1)=0\\\\x=+4

Hence, the oxidation state of 'Ti' is, (+4)

(f) NaH

Let the oxidation state of 'Na' be, 'x'

x+(-1)=0\\\\x=+1

Hence, the oxidation state of 'Na' is, (+1)
