In gamma decay, no change in proton number occurs, so the atom does not become a different element
Answer:
The solid will sublime into a gas
Explanation:
See the phase diagram attached (the diagram is not an exact representation of this case, it is only illustrative). You starts at point A, that is, a point below triple point pressure (220 mmHg is lower than 225 mmHg) and to the left of triple point temperature (-35 °C is lower than -24.5 °C). Then, you move to point B, which is at the same pressure at A but its temperature is to the right of triple point temperature (0°C is greater than -24.5 °C).
Answer:
Name: Aluminum Sulfite
Explanation:
Systematic nomenclature: dialuminium tris [trioxosulfate (IV)]
Oxoanions: anions derived from removing H + from an oxo acid with a vulgar name:
(SO3)3^-2 (sulfite)
Metal cation according to valence number:
Al (III) or Al+3 (as a cation) (Aluminum)
There are different types of salts, in this case we have a simple salt and the nomenclature for binary substances is used when only one class of cation and one class of anion are present
So:
Al2(SO3)3: Aluminum Sulfite
Ions are charged particles that form when an atom (or group of atoms) receives or loses an electron, and ionic compounds are composed of these charged particles. An anion is a negatively charged ion, whereas a cation is a positively charged ion. Here Al₂(SO₃)₃ is aluminium sulfite.
Ionic compounds are defined as substances that are joined by ionic bonds. In order to reach their closest arrangement as a noble gas, elements can either gain or lose electrons. For the completion of the octet, ions are formed (either by gaining or losing electrons), which aids in their stabilization.
The name of the compound Al₂(SO₃)₃ is aluminium sulfite.

Given:
Molar mass CO2 is 44.01 g/mol
25.5 g of CO2
Required:
Moles of LiOH
Solution:
Balanced equation is:
2LiOH +CO2 → Li2CO3 + H2O
25.5g CO2 (1 mole CO2/44.01 g/mol CO2)(2 moles LiOH/1 mol CO2) = 1.16 moles LiOH
Molarmass carbon dioxide is 44.01 g/mol, 1.16 moles of LiOH are needed to react completely with 25.5 g of CO₂.
Stoichiometry and the molar ratios of CO₂ and LiOH must be used to calculate the number of moles of LiOH required to totally react with 25.5 g of CO₂.
The reaction between CO₂ and LiOH has the following chemical formula:
CO₂ + 2LiOH -> Li₂CO₃ + H₂O
Now,
Molar mass of CO₂ = 44.01 g/mol
Mass of CO₂ = 25.5 g
Number of moles of CO₂ = Mass of CO2 / Molar mass of CO2
= 25.5 g / 44.01 g/mol
≈ 0.58 moles of CO2
As per this,
Number of moles of LiOH = 2 * Number of moles of CO2
= 2 * 0.58 moles
= 1.16 moles of LiOH
Thus, 1.16 moles of LiOH are needed for the given reaction.
