Explanation:
For AX type ceramic material, the number of formula per unit cells is as follows.
or, 
where, n' = no. of formula units per cell
= molecular weight of cation = 90.5 g/mol
= molecular weight of anion = 37.3 g/mol
= volume of cubic cell = 3.55 
a = edge length of unit cell = 
= Avogadro's number = 
= density = 3.55
Now, putting the given values into the above formula as follows.
= 
= 0.9
= 1 (approx)
Therefore, we can conclude that out of the given options crystal structure of cesium chloride is possible for this material.
Answer:
<h2>6.75 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2.7 × 2.5
We have the final answer as
<h3>6.75 g</h3>
Hope this helps you
A- and H3O+ interact, causing A-'s concentration to drop and [HA] to rise. As a result, the [NaA]/[HA] ratio declines. Because of the base content, the buffer's pH will be more acidic. The concentration of the acid, HA, has increased while A- has decreased.
What is Acid?
Any material that when dissolved in water has an acidic taste, can alter the colour of some indicators (such as reddening blue litmus paper), can react with some metals (such as iron) to release hydrogen, can combine with bases to produce salts, and can accelerate some chemical reactions (acid catalysis). Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These chemicals contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they are in solution.

Most likely the equation yields a new compound XY. This is a synthesis reaction. <span>Synthesis
reaction is a reaction where two or more substances combine to form a new
compound. It is a reaction which releases energy in the form of heat and
light. Therefore, it is an exothermic reaction.</span>
II think thihe answer is to be part of the acid to be honest
