Answer:
1. Compound A is propanol which reacts with sodium metal with the evolution of hydrogen gas and this is the gas which is causing little explosion. Propanol is normally liquid at room temperature.
2. Compound B is propene since it decolourises bromine water. This reaction is normally an addition reaction.
3. Compound C is propane since it gives a substitution reaction with chlorine.
Explanation:
Answer:
compound machine
Explanation:
A machine made of two or more simple machines is known as a compound machine.
They are usually derived by coupling or joining simple appliances together to make one compound device.
- This is done to increase mechanical advantage and to perform different tasks.
- Common examples are bicycles, shovels etc.
Answer:
Density of 40 mL of liquid that has a mass of 20 g = 20 / 40 = 0.5 g / cc
The correct option are option C,E that is bonds between a sulfur atom and two hydrogen atoms were broken. Zinc atom formed a bond with one sulfur atom.
<h3>
What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
In the give reaction, bonds between a sulfur atom and two hydrogen atoms were broken. zinc atom formed a bond with one sulfur atom.
Therefore, the correct option are option C,E.
