Answer:
Stars which never disappear below the horizon are called <u>circumpolar</u> stars.
Answer:
its atomic number
Explanation:
which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to uranium.
There are six bond pair electrons around the central atom in Sulfur Hexafluoride. In order to attain the structure of least possible energy the Fluoride atoms attain the angle of 90° with respect to each other. And the bond pair electrons after maximum repulsion attain a
Octahedral Shape as shown below,
Answer:
because of accumulation of lactic acid due to anaerobic respiration
Answer:
k = 3.2 x 10¹¹
Explanation:
The equilbrium taking place is:
- N₂(g) + 3Cl₂(g) ↔ 2NCl₃(g)
And the expression for the equilbrium constant <em>k</em> is
- k = [NCl₃]² / ( [N₂] * [Cl₂]³)
We are given all the required data from the problem, so now we <u>solve for k</u>:
- k = (1.9x10⁻¹)² / ( (1.4x10⁻³) * (4.3x10⁻⁴)³ )
