<span>In order for an ionic compound to be created, there has to be a reaction between a metal and a non-metal. Having this in mind, the correct answer is A. strontium and chlorine. Strontium (Sr) is an alkaline earth metal, whereas chlorine (Cl) is a halogen gas, so a non-metal. There is no this type of a combination of metal + non-metal in other options, so only A is correct.</span>
Using the general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
(105*220)/275 = (P₂*95)/310
(105*220)*310/275 = P₂*95
(105*220*310)/(275*95) = P₂
274.11 = P₂
P₂ = 274.11 kPa
New Pressure = 274.11 kPa
Answer:
1,2,3,5,7,8,9
Explanation:
are all physical properties
Salt is usually formed during neutralization reactions,
that is the reaction of an acid and a base. This is illustrated as follows:
<span>HX + YOH --> XY
+ H2O</span>
where XY is the salt
From the given choices, the only pair of acid and base is:
<span>Vinegar and antacids</span>
