Answer:
In a conventional optical microscope, objects less than about 200 nanometers apart cannot be distinguished from one another. ... Although electron microscopes produce a detailed image of very small structures, they cannot provide an image of the proteins that make up those structures.
Answer:
Turning Sugar into Caramel
Explanation:
You turn sugar into caramel by burning sugar. Burning sugar is a chemical change.
Answer:
Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
They answer questions like, like "What makes up this material?," "How does this material change when heated or cooled,?" What happens when I mix this material with another material,?" and "What rules determine how materials change in different situations?" What makes up Chemical X?
<em>Answer </em>

so, <em>mass</em><em> </em><em>(</em><em>g</em><em>)</em><em>=</em><em> </em><em>no</em><em>. </em><em>of</em><em> </em><em>mol</em><em>es</em><em> </em><em>×</em><em> </em><em>molecular </em><em>wight </em>
Explanation:
Li molecular wight equal to 6.941
mass (g)=3.29×104 <em>mol</em><em> </em><em>×</em><em>6</em><em>.</em><em>9</em><em>4</em><em>1</em><em> </em><em>=</em><em>2</em><em>3</em><em>7</em><em>4</em><em>.</em><em>9</em><em>3</em><em>g</em><em> </em><em>of</em><em> </em><em>lithium </em>
The given question is incomplete. The complete question is ;
Ammonia gas can be prepared by the following reaction:

In an experiment, 27.6 g of ammonia gas,
, is produced when it was predicted that 50.2 g of
would form.
What is the theoretical yield of
? What is the actual yeild of
? What is the percent yeild of
?
Answer: a) 50.2 g
b) 27.6 g
c) 5.0 %
Explanation:
a) Theoretical yield is defined as the amount of the product that is possible in the reaction.
Theoretical yield of
= 50.2 g
b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.
Experimental yield of
= 27.6 g
c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.


Hence percentage yield for the reaction is 55.0 %.
