A chemical property refers to that which cannot be physically determined. From the choices given above, the chemical property of one of the student's materials is the reactivity of the copper strip. Thus, the answer to this item is letter B.
Brooo we have the same name
Answer:
E.
Explanation:
All answers other than E have the incorrect bonding capabilities or other incorrect information.
Answer:
The density of liquid is 3 g/mL.
The mass of liquid is 60 g.
The volume of liquid is 10 mL.
Explanation:
Given data:
Density of liquid = ?
Mass of liquid = 30 g
Volume of liquid = 10 mL
Solution:
d = m/v
d = density
m = mass
v = volume
Now we will put the values in formula.
d = 30 g/ 10 mL
d = 3 g/mL
The density of liquid is 3 g/mL.
2nd:
Given data:
Density of liquid = 2 g/mL
Volume of liquid = 30 mL
Mass of liquid = ?
Solution:
d = m/v
2 g/mL = m/ 30 mL
m = 2 g/mL×30 mL
m = 60 g
The mass of liquid is 60 g.
3rd:
Given data:
Density of liquid = 5 g/mL
Mass of liquid = 50 g
Volume of liquid = ?
Solution:
d = m/v
5 g/mL = 50 g/ v
v = 50 g/5 g/mL
v = 10 mL
The volume of liquid is 10 mL.
Answer:
Forests are renewable
Explanation:
Forests can grow again, but it takes forever to grow a new one so it shouldn't be taken for granted! You can remake a whole new forest, but it will take around 50 years and a lot of animals will die without them before that time comes!
But then again, it could be a non-renewable resources; because it takes so long to grow a new one!
Hope this helps!
