<h2>Answer : Option D) Heterogeneous mixture</h2><h3>Explanation : </h3>
A mixture in which particles are not evenly distributed and particles keep their unique properties are called as heterogeneous mixture.
Usually, in heterogeneous mixture the substances are not evenly distributed and they can be easily separated through any physical methods. Also the components retains their original/unique properties in the mixture. It usually contains various particles from different substances that are not uniformly distributed throughout the mixture.
Answer:
The cycling of matter is important to many Earth processes and to the survival of organisms the existing matter must cycle continuously for this planet to support life Water, carbon, nitrogen, phosphorus, and even rocks move through cycles If these materials did not cycle, Earth could not support life.
Explanation:
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
Answer:
The depth of the lake is 67.164 meters.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in bubble= ?
= final pressure of gas = 0.980 atm
= initial volume of gas = 
= final volume of gas = 8.00 × V
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
pressure of the gas in bubble initially is equal to the sum of final pressure and pressure exerted by water at depth h.
Where :
density of water = 
g = acceleration due gravity = 
h = 67.164 m
The depth of the lake is 67.164 meters.
