Hi!
I believe there are 4 main chemicals in space uracil, cytosine, thymine, and pyrimidine :)
Answer:
Given: 800g S02 Unknown: ?g S
Explanation:
Problem Type: mass - mass
(I've done this before and my teacher gave that answer)
Answer:
The answer to your question is: 0.1 M
Explanation:
data
Volume of AgNO3 = 20.00 ml
1000 ml -------------- 1 l
20 ml --------------- x
x = 20x 1 /1000 = 0.02
AgCl = 0.2867 g
MW of AgCl = 35.45 + 107.9 = 143.35 g
143.35 g -------------- 1 mol
0.2867 g ------------- x
x = 0.2867 x 1 / 143.35 = 0.002 moles of AgCl
From the balance reaction we see that the proportion of AgNO3 to AgCl is 1:1, then
1 mol of AgNO3 -------------------- 1 mol of AgCL
x --------------------- 0.002 moles of AgCl
x = 0.002 moles of AgNO3
This moles of AgNO3 are in 20 ml or 0.02 liters
So, Molarity = # moles/liter
Molarity = 0.002 moles/ 0.02 = 0.1 M
I would say answer choice A) positive after checking, hope this helps
