Explanation:
A compound containing only two elements is called a binary compound.
(a). The compound HCN contains a hydrogen ion and cyanide ion. Hence, the name of HCN is hydrogen cyanide.
An aqueous solution of hydrogen cyanide is known as hydrogen cyanide solution.
(b). The compound HF contains a hydrogen ion and a fluorine ion. The suffix -ide will be added to its name. So, the name of this compound is hydrogen fluoride.
An aqueous solution of HF is known as hydrogen fluoride.
(c). The compound contains two hydrogen atoms and one sulfur atom. The suffix -ide will be added to its name. So, the name of this compound is hydrogen sulfide.
An aqueous solution of this compound is known as hydrogen sulfide solution.
Answer:
the products formed are : -
1. CaCO3 - Calcium Carbonate
2. NaCl - Sodium Chloride
Explanation:
Calcium chloride reacts with Sodium carbonate to form Calcium carbonate and Sodium chloride. this reaction is a double displacement reaction.
here's the balanced chemical equation for the above reaction : -
CaCl2 + Na2CO3 =》CaCO3 + 2 NaCl
<u>Answer:</u> The total pressure inside the container is 1.07 atm
<u>Explanation:</u>
To calculate the total pressure of the container, we use the equation given by Raoult's law, which is:
where,
= partial pressure of nitrogen = 0.800 atm
= total pressure
= mole fraction of nitrogen = 0.750
Putting values in above equation, we get:
Hence, the total pressure inside the container is 1.07 atm
Answer: b. 322.5 mL
Explanation:assume constant pressure, then
693/(273.15+45) = v/(273.15-125)
v= 693*148.15/318.15 = 322.7
