Particles in a gas are always bumping against one another, it would be more accurate to compare it to a dance floor honestly
Answer:
the equation for cylinders is V = (pi)r2h
none of these are even close but i can do a little more research
sorry if this one wasnt as much help
Answer:
1.626 M
Explanation:
Let's start by <u>calculating how many grams of C₂H₆O₂ are there per mL of solution</u>:
- 1 mL of solution weighs 1.40 g.
- 1.40 g of solution * =0.1008 g C₂H₆O₂
So the C₂H₆O₂ concentration can be expressed as 0.1008 g/mL.
Now we <u>convert g/mL to molarity</u>, using the <em>molar mass of C₂H₆O₂:</em>
- 0.1008 g C₂H₆O₂ ÷ 62 g/mol = 1.626x10⁻³ mol C₂H₆O₂
(1 mL = 0.001 L)
- 1.626x10⁻³ mol C₂H₆O₂ / 0.001 L = 1.626 M
B. Are produced only by living things
Answer:
Explanation:
Hello!
In this case, for the undergoing chemical reaction:
We evaluate the yielded moles of zinc hydroxide by each reactant as shown below:
In such a way, since the water yields a smaller amount of zinc hydroxide we conclude it is the limiting reactant so the maximum mass is computed below:
Because the water limits the yielded amount of zinc hydroxide.
Best regards!
