If a base is added to water, what will occur?

1 answer:

6 0

This will increase the concentration of [OH-] ions.
For example:
- Ammonia NH3 (base):
NH3(aq) + H2O (l) → NH4+ + OH-

and
-NaOH:
NaOH(s) + H2O(l) → Na+ + OH-
and KOH:
KOH(s) → K+(aq) + OH-(aq)

So we can see that the base increase the [OH-] & increase the characteristic anion [OH-] of the solvent.

Which of these organelles produces h2o2 as a by-product?

Gala2k [10]

The parts constituting a single cell are called its organelles. Examples are ribosomes, mitochondria, endoplasmic reticulum, Golgi bodies and many more. You might confuse the answer to this question because there is an organelle named Peroxisome. It is called such because it synthesizes Hydrogen Peroxide or H₂O₂. It breaks the compound into its individual components, water and oxygen. So, it uses up H₂O₂, not produce it. The organelle that actually produces H₂O₂ as a by-product is the mitochondria through the process of respiration.

Arrange the following ionic compounds in order of decreasing amount of energy released in lattice formation: LiCl , CaO , AlN ,

nadya68 [22]

Answer:in decreasing pattern; AlN>CaO>LiCl>KI.

Explanation:

The energy required to break apart an ionic solid and convert its component atoms into gaseous ions is known as the LATTICE ENERGY.

LATTICE ENERGY has a trend on the periodic table. The trend shows the relationship between LATTICE ENERGY AND THE ATOMIC RADIUS.

Lattice energy is related to solubility, volatilty and hardness.

Down the group on the periodic chart, the ATOMIC RADIUS INCREASES, THE LATTICE ENERGY DECREASES. Which means that between Lithium ion and potassium ion, Lithium ion will have higher lattice energy than that of potassium.

The trend ACROSS THE PERIOD is that, as we go across the period, the charges on metals increase,consequently INCRESING THE LATTICE ENERGY. Between Aluminum ion with a positive charge of three and Calcium with a positive charge of two, Aluminium ion has higher charge, which means it has more lattice energy than calcium.

If the vapor pressure of pure benzene is 96.1 mm Hg, what must the vapor pressure of pure toluene be in order for the 50/50 % mi

mylen [45]

Answer:

$P_{tol}=30.34mmHg$

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the vapor pressure of pure toluene by using the Raoult's law as shown below:

$y_{tol}P_{mix}=x_{tol}P_{tol}\\\\y_{ben}P_{mix}=x_{ben}P_{ben}$
