Answer:

a . Shift it to the right toward the products.

Explanation:

In the reaction, if more of the reactant A is added to the system, the reaction will shift towards the products.

If a system at equilibrium is disturbed by changing the concentration of one of the substances, all the concentration will change until a new equilibrium point is reached.
If we add more reactants, the concentration is increased and the reaction shifts to the right so as to maintain the constancy of the equilibrium constant.

How many protons, electrons, and neutrons does the following isotope contain?<br> 27 A13+

Lapatulllka [165]

Hey there!

27 tells us the sum of protons and neutrons is 27.

Al tells us we have 13 protons.

3+ tells us that there are 3 less electrons than protons.

13 + n = 27

neutrons = 14

13 - 3 = 10 electrons

27Al3+ has 13 protons, 14 neutrons, and 10 electrons.

Hope this helps!

Which kind of atoms would typically form an ionic bond?

Sunny_sXe [5.5K]

An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between at

15.0 mL of an unknown clear liquid is added to a 50 mL graduated cylinder. The mass of the liquid is determined to be 12.7 grams

sveticcg [70]

Answer:

$\boxed {\tt A. \ d=0.85 \ g/mL}$

Explanation:

Density is found by dividing the mass by the volume.

$d=\frac{m}{v}$

The mass of the liquid is 12.7 grams.

We know that 15 mL of this liquid was added to a 50 mL graduated cylinder. Therefore, the volume is 15 mL. The 50 mL is not relevant, it only tells us about the graduated cylinder.

$m= 12.7 \ g\\v= 15 \ mL$
