What is the Empirical Formula when the Molecular Formula is Sb17Br21

1 answer:

5 0

Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

Question 3 (please help)

poizon [28]

Answer:

the Answer is B

Explanation:

If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size. Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species.

hope this helps have a good day :)

A group of students is comparing the graphs of strong acid-strong base and weak acid-strong base titration curves, where the bas

erma4kov [3.2K]

The initial pH for the weak acid-strong base curve is higher than the initial pH for the strong acid-strong base curve. Hence, option A is correct.

Weak acids are acids that don't completely dissociate in solution.

A weak acid is an acetic acid. It has a of 1.8⋅ $10^{-5}$ . Calculate how much it will dissociate in water. Since acetic acid is a weak acid so large part will not dissociate completely.

$k_a=\frac{[CH_3COO^-]H^+]}{[CH_3COOH]}$

B is not true, it shows the titration curve for weak/strong acid titrated with a strong base. When choosing an indicator for colourimetric titration select one so that the pH jump at the equivalence point contains the interval p±1. Phenolphthalein has a p≈9, so to decide if it is a suitable indicator check if the pH jumps from 8 to 10 at the equivalence point.

C is not true either because of the very slow reaction.

Why is a magnetic field a vector quantity?

Alik [6]

Answer:

Explanation:

a vector quantity must have a direction. without a direction the value is called a scalar quantity

ie: velocity is a vector because it is how fast an object moves in a certain direction. speed is a scalar because it is how fast an object moves regardless of direction
