Circle only those of the following reactions that are redox reactions:
Citrus2011 [14]

Answer: options B,D and F

Explanation:

Since redox reactions are those which involves both oxidation and reduction

In B , Cu is oxidized and S gets reduced

D, Na gets oxidized and hydrogen gets reduced

F, carbon gets oxidized and Oxygen gets reduced

In g, there is no change in oxidation no of s in both product and Reactants is same +4

Similarly in the case of Ag and Mg.

A molecule in which the central atom forms three single bonds and has one lone pair is said to have a ________ shape.
nignag [31]

Answer : The correct option is, (c) pyramidal

Explanation :

As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.

There are total 4 electron pairs. So, the hybridization will be sp^3 and the electronic geometry of the molecule will be tetrahedral.

But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.

Hence, correct option is, (c) pyramidal

A test light with an electrical resistance of 9.00 S2 draws a current of 1.50 A when
yuradex [85]

Answer:

20.25 W

Explanation:

Applying,

P = I²R.................... Equation 1

Where P = Power, I = current drawn by the test light, R = Resistance of the test light

From the question,

Given: I = 1.5 A, R = 9.00 Ω

Substitute these values into equation 1

P = (1.5²)(9)

P = 2.25×9

P = 20.25 W

Classify each of the following as a compound, a homogeneous mixture, or a heterogeneous mixture: (a) distilled water; (b) gasoli
Marina CMI [18]

Explanation:

A mixture which shows presence of uniform composition of solute particles into the solvent is known as a homogeneous mixture.

  • Distilled water is a clear solution in which there is uniform composition of solute particles into the solution.
  • Gasoline is mixture of different compounds which are evenly distributed. Therefore, it is also a homogeneous mixture.
  • Wine is also a clear solution in which particles are evenly distributed. Hence, it is a homogeneous mixture.

On the other hand, a mixture which shows non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.

  • Beach sand is a mixture of different particles present in varying composition. Hence, it is a heterogeneous mixture.
  • Also, in air there are different gases present in different composition. Mover over, there is presence of fog and smoke into the air. Hence, it is a heterogeneous mixture.
