Explanation

Remember that water has 2 lone pairs on oxygen.

Hence, according to VSEPR theory, the water molecule arrives at a bent or a V-shape

Due to the presence of lone pair-lone pair, lone pair-bond pair and bond pair-bond pair repulsions

Explanation

To find the range of a data set, we need to determine the difference between the maximum and minimum values in the set.

Given data set of student ages: 16, 17, 18, 16, 19, 20

1. The minimum age in the data set is 16.

2. The maximum age in the data set is 20.

3. To calculate the range, we subtract the minimum age from the maximum age:

Range = 20 = 16 = 4

Explanation

When a copper strip is placed in a solution of FeSO₄, no significant reaction occurs because copper does not have a stronger tendency to oxidize compared to iron.

The statement "Cu will be precipitated down" is because there is no source of Cu²⁺ ions in the solution to precipitate out.

Copper remains as a metal, and iron remains in the Fe²⁺ ionic form in the solution.

Explanation

Bulk modulus of elasticity is defined as ratio of hydraulic stress to the corresponding the volumetric strain within the elastic limit.

Bulk modulus K=FVAΔV=Δp⋅VΔV.

Explanation

Electrons typically have greater kinetic energy compared to protons and neutrons because of their significantly lower mass.

Explanation

when sin θ < 0 and cos θ < 0, the terminal arm of the angle θ lies in the third quadrant of the Cartesian plane.

Explanation

One root = 2  

Equation: 2x² + ax + 6 = 0

Using factor theorem, substitute x = 2:

2(2)² + a(2) + 6 = 0  

⇒ 8 + 2a + 6 = 0  

⇒ 2a + 14 = 0  

⇒ 2a = -14  

⇒ a = -7
