Answer:
quoted, but you can learn from this.
Explanation:
"The different types of microscopes are all necessary because not all experiments require the same level of magnification.<em> [ For dissections low magnification is sufficient, so a dissecting microscope works very well, while for viewing single cells the 1000 fold magnification of a compound light microscope is more than adequate. ] " </em>
Answer:
because of the material, they are made of
Explanation:
like a paperclip and a car door maybe they both are metal or steel whatever they both can conduct energy. because of what they are made of.
i hope this helps and sorry i am rushing, i also just woke up
Answer:
6.32g
Explanation:
The mass of 1 mol of K is 40g, and the reaction needs 2 moles of K to produce 2 moles of KCl, so it needs 80g of K to produces 151g of KCl.
So you make a rule of three:
x = 3.35•151/80
x = 6.32g
Answer:
a. alkyne
b. alkane
c. alkyne
d. alkene
Explanation:
The general formula for each class of compound is given below
Alkane: 
Alkene: 
Alkyne: 
(assuming single multiple bonds)
Now let us classify according to the above formulas:
a. It has two hydrogen atoms less than the two times of carbon atoms hence, it's alkyne
b. It has two hydrogen atoms more than the two times of carbon atoms hence, it's alkane
c. It has two hydrogen atoms less than the two times of carbon atoms hence, it's alkyne
d. It has hydrogen atoms two times of carbon atoms hence, it's alkene
