Answer:
1 mole of lithium is 7 grams. we know this from it's relative molecular mass.
if 1 mole is 7 grams then x moles is 0.56 grams
we can equate them by saying (1/x)=(7/0.56)
after cross multiplying, we get 7x=0.56, x will be equals to 0.56/7
x=0.08 grams
Answer:
The original volume of the gas is 0.001 mL
Explanation:
This easy excersise can be solved by the law for gases, about pressure and volume; the volume of a gas is inversely proportional to the pressure it exerts.
We can propose the rule by this formula:
P₁ / V₁ = P₂ / V₂
We replace data given: 1.50 atm / V₁ = 0.50 atm / 750 mL
As the rule says, that volume is inversely proportional, and the pressure was decreased, volume must be lower than 750 mL.
1.5atm / (0.5 atm / 750mL) = V₁
V₁ = 0.001 mL
Answer:
magnification and resolution
Explanation:
Two parameters are especially important in microscopy: magnification and resolution. Magnification is a measure of how much larger a microscope (or set of lenses within a microscope) causes an object to appear.
Answer:
A
Explanation:
because they are non polar so would not conduct electricity :)
Answer:
Explanation:
Hello!
In this case, for the undergoing chemical reaction at equilibrium:
Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:
Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
Best regards!
