1. 2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)
2. 2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)
3. 2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)
<h3>Further explanation</h3>
There are several reactions that can occur in a chemical reaction: single replacement, double replacement, synthesis, decomposition or combustion, etc.
1.Al(s)+HCl(aq)⇒AlCl₃(aq)+H₂(g)
type : single replacement
balance :
2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)
2. AgNO₃ (aq) + Cu (s) ⇒ Cu(NO₃)₂ (aq) + Ag (s)
type : single replacement
balance :
2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)
3. C₃H₈O + O₂ ⇒ CO₂ + H₂O
type : combustion of alcohol
balance :
2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)
Sulfur reacts with oxygen to produce sulfur dioxide. That is for every mole of sulfur reacted, one mole of sulfur dioxide also is produced. With the given mole of sulfur dioxide, the amount of sulfur in mass is determined by multiplying the number of moles to the molar mass of sulfur (32 g/mol).
Answer:
they don't depend on the temperature
1 kpa = 7.5 mm of Hg [Remember it or can be found on internet ]
So, 275 kpa = 7.5 x 275 = 2062.5 mm of Hg
Answer:
The given statement is false.
Explanation:
Displacement is a vector quantity which represent shortest distance form initial position to final position.
Velocity of an object is defined as ratio of displacement of object to that of the time taken by object to move from its initial position to final position.
In displacement vs time graph the slope of the graph represent the velocity. Whereas slope of velocity vs time graph gives acceleration.
