<u>Answer:</u> The process that is used to prepare ceramic is sintering.
<u>Explanation:</u>
Sintering is defined as the process in which number of particles are fused together to form one solid mass by the applying pressure at high temperatures.
Ceramic is an material that is made by taking mixtures of clay, earthen elements, powders and water.
When this mixture (slurry of the powders) is heated at a very high temperature and under high pressure, ceramic is formed.
Hence, the process that is used to prepare ceramic is sintering.
Answer:
Molecules of oil are bigger than of water and therefore do not mix.
Hope this helps
I’m pretty sure it’s D. Hope that helps! Correct me if I am wrong.

Answer:
HX (aq) + H₂O (l) ⇄ H₃O⁺ (aq) + X⁻ (aq)
Acid Base Conj. acid Conj. base
Explanation:
The equation is:
HX (aq) + H₂O (l) ⇄ H₃O⁺ (aq) + X⁻ (aq)
This is the typical equilibrium for a weak acid. It would complete if we notice the Ka.
HX (aq) + H₂O (l) ⇄ H₃O⁺ (aq) + X⁻ (aq) Ka
1 mol of hypothetic HX acid react to 1 mol of water in order to release a proton and make hydronium and generate the X⁻ anion.
HX will be the acid, in this case a weak one and water will be the base. Water is able to accept a proton to make itslef hydronium
Hydronium is the conjugate acid.
The X⁻ will be the conjugate strong base.
This ion can generate the acid form again, that's why it is strong, because it can make hydrolisis.
X⁻ (aq) + H₂O (l) ⇄ HX (aq) + OH⁻(aq) Kb
In this case, the anion will be the conjugate base which it takes a proton from water (acid form) to make a conjugate acid, the HX and a conjugate base, OH⁻
