A. 1
B. +1
C. -1
D. 0
Answer:
Elements in group 17 form C. -1 ions
hexagonal
triclinic
cubic
Answer : The correct option is, Cubic.
Explanation :
As there are seven types of crystal systems which are cubic, tetragonal, orthorhombic, monoclinic, triclinic, rhombohedral and hexagonal.
A unit cell is characterized by the axial length (a, b and c) and axial angle parameters which decide the size and shape of the unit cell.
In tetragonal crystal system, and
In hexagonal crystal system, and
In triclinic crystal system, and
In cubic crystal system, and
Hence, the correct option is, Cubic.
b. more easily compressed.
c. less organized.
d. more likely to flow.
The bouncing back of light waves observed when light waves hit ice and most of them bounce off and radiate back into space is called reflection.
Light waves are a form of waves which produces visible sensitization of the eyes
Light waves have properties of waves such as:
When light waves hit ice, most of them bounce off and radiate back into space.
This property of light waves is known as reflection.

When light waves hit ice, most of them bounce off and radiate back into space, hence, ice is best described as a reflective surface.
A reflective surface is one which can cause incident light to bounce back (reflection).
According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident lightreflects off the ice surface.
Therefore, the ice surface is best described as a reflective surface.

The mass in grams of 2.56x10-3 mol of iron is 0.143 g.
To calculate the mass in grams of 2.56x10-3 mol of iron, you need to use the molar mass of iron. The molar mass of iron is 55.845 g/mol. To find the mass in grams, you can use the following step-by-step calculation:
Mass (g) = Number of moles x Molar mass
Mass (g) = 2.56x10-3 mol x 55.845 g/mol = 0.143 g
