To balance chemical equations, you should just remember that the number of atoms of an element in the reactant side must be equal to the number of atoms of the same element in the product side. The order of the substances doesn't matter. What is important that the equation balances.
Option 2: BCC
The expression for density of cell is as follows:
...... (1)
Here, n is number of atom per unit cell, A is atomic mass, is volume of crystal and is Avagadro's number.
Also, the expression for volume of crystal is as follows:
The atomic weight, density and Radius of atom is given 43.1 g/mol, and 0.122 nm respectively.
Converting radius into cm:
Thus,
Putting the value to calculate volume first:
Now, putting all the values in equation (1)
On rearranging,
The number of atom per unit cell is 2 for body centered cubic lattice thus, correct option is BCC.
Answer:
The correct answer is - alkali or base.
Explanation:
The litmus paper test is used to find whether a solution is basic or acidic. In a litmus paper test, a litmus paper is a dip in a particular or desired solution that turns the color of litmus paper to red, blue, or purple based on the pH of the solution.
If the paper turns red it means the solution is acidic, in a neutral solution it turns to the purple color and if the blue color appears then it is a basic or alkali solution. The solution of baking soda turns litmus paper into blue color which means baking soda is most likely a base.
Answer:
If the amplitude increases, the velocity or wavelength doesn't neccecarily change, since they are not related.
It is either a heavier object than object B or it is being pulled away from object B
