Answer:
Dissolving ice tea mix in water is a chemical change
Explanation:
It is a chemical change because you can not bring back the ice tea mix back if you mix it in water.
Hope it helps
Answer:
Fe is just the shortened version of Iron whereas Fe2+ is a positive ion,cation to be more specific
Multiple states of matter - mixture
Same state of matter - pure
Separated physically- mixture
Consistent properties - pure
Can’t be separated- pure
Can’t be a single element - mixture
Seismic waves
Explanation:
Seismic waves are disturbances that transmits energy elastically and let's scientist have a glimpse of the interior of the earth.
These waves can pass through any component layer of the earth due to their unique properties.
There are four types of seismic waves but the two body waves are the most important in studying the earth's interior.
- Seismic p-waves can pass through any earth materials as they are longitudinal waves.
- Seismic s-waves are shear waves and can only pass through solids. liquids and gases cannot be sheared.

Answer: The mass density is 1166.36 
.
Explanation:
Given: Weight of sample in air 
= 500 N
Weight of sample in alcohol 
= 200 N
Specific gravity = 0.7 = 
Formula used to calculate Buoyant force is as follows.
Hence, volume of the material is calculated as follows.
where,
= Buoyant force
= specific gravity
g = acceleration due to gravity = 9.81
Substitute the values into above formula.
Now, mass of the material is calculated as follows.
Therefore, density of the material or mass density is as follows.
Thus, we can conclude that the mass density is 1166.36 .
