B
Explanation:
I looked it up and found the answer lol
Answer:
The volume increases,
Final volume is 2.1L
Explanation:
Based on Boyle's law, the absolute temperature of a gas is directly proportional to the volume of the gas.
As the balloon change increases its temperature, the volume increases
The Boyle's equation is:
V1T2 = V2T1
<em>Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
V1 = 2.0L
T2 = 35°C + 273.15 = 308.15K
V2 = ?
T1 = 25°C + 273.15 = 298.15K
2.0L*308.15K = V2*298.15K
2.1L = V2
<h3>Final volume is 2.1L</h3>

Because the reaction occurs between a metal and non metal
CL=2,8,7
C
Answer:
2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g)
Explanation:
The reaction is a displacement reaction.
The reaction does not commence immediately because the Al(aluminum) has Al2O3 (Aluminum oxide) which protect it from reacting with water.
It takes some time for the HCl (hydrochloric acid) to eat the coating, then the reaction proceed vigorously to produce hydrogen gas bubbles. Generally metals that are above hydrogen in the electrochemical series tend to displace Hydrogen from Hydrochloric acid. The more negative the electrochemical volts the more the tendency to lose electron. Metal above hydrogen have negative evolts while those below have positive evolts
