Answer:
1.
2.
Explanation:
1.Momentum is given as the product of mass by velocity of an object.
Momentum,
m=1,500kh, v=6m/s
2.Momentum,
m=7800kg, v=30m/s
new mass=7800+800=8600
As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.
0.843 moles would be the answer
Answer:
Xenon is less reactive.
Explanation:
Xenon is a noble gas with 8 valence electrons whereas bromine is a halogen with 7 and is very reactive.
Answer:
H-F is a polar covalent molecule in which dipole-dipole interactions exists
The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.
<h3>What is the law of mass of conservation?</h3>
The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.
