Answer:
Autosexuality means people are more attracted to themselves than to others and may prefer masturbation to sex with a partner.
Answer:
159.609 g/mol
Explanation:
According to the CuSO4.5H2O (k) heat CuSO4 (k) + 5 H2O (g) equation, the crystal water amount of copper sulfate and its rough formula will be calculated.
Weight of copper sulfate containing crystal water = m1 = 249.62… g
Weight of copper sulfate without crystal water weighed = m2 = 159.62 g
Accordingly, calculate the x and y values in the molecular formula of copper sulfate (xCuSO4.yH2O).
The mass of sodium sulfite that was used will be 1,890 grams.
<h3>Stoichiometric problems</h3>
First, the equation of the reaction:
The mole ratio of SO2 produced and sodium sulfite that reacted is 1:1.
Mole of 960 grams SO2 = 960/64 = 15 moles
Equivalent mole of sodium sulfite that reacted = 15 moles
Mass of 15 moles sodium sulfite = 15 x 126 = 1,890 grams

#SPJ1
Decrease the concentration because slower rate = less concentration
Answer:
0.083 moles KCl
Explanation:
We have 252 mL of 0.33 M KCl. "M" is molarity, and it's measured in mol/L. Since we know the molarity is 0.33 mol/L, in order to find how many moles 252 mL is, we need to multiply our given volume by the molarity.
However, our given volume is in mL, so let's convert to L first by dividing 252 by 1000 (because there are 1000 mL in 1 L):
252/1000 = 0.252 L
Now, we can multiply 0.252 L by 0.33 mol/L to get moles since the L units will cancel out:
0.252 L * 0.33 mol/L = 0.08316
We have two significant figures here, so round 0.08316 to 0.083.
The answer is 0.083 moles.
Hope this helps!
