Answer:

v_{solute}=25mL

Explanation:

Hello there!

In this case, according to the by-volume concentration of this solution, it is possible for us to use its mathematical definition as shown below:

\%v=\frac{v_{solute}}{v_{solution}}*100\%

Thus, given the percent and the volume of the solution, we can solve for the volume of ethanol (solute) as shown below:

v_{solute}=\frac{\%v*v_{solution}}{100\% }\\\\v_{solute}=\frac{5.00\%*500mL}{100\%}\\\\ v_{solute}=25mL

Best regards!

Represent the formation of cations for the following metal atoms using electron dot structures. (a) Al (b) Sr (c) Ba​
vagabundo [1.1K]

the formation of cations by using electron dot structures are :

a) Al

.

Al .    losing the three valence electrons makes the Al³⁺

.

b) Sr :  

  Sr :  losing the two valence electrons makes Sr²⁺

c) Ba

: Ba , losing the two valence electrons makes it Ba²⁺

A Lewis electron dot diagram is a representation of the valence electrons of an atom that employments specks around the image of the element. The number of dots equals the number of valence electrons within the molecule. These dots are arranged to the right and left and over and underneath the symbol, with no more than two dots on a side. Cations are the positive ions shaped by the loss of one or more electrons. The foremost commonly shaped cations of the representative elements are those that include the loss of all of the valence electrons.

How do you convert kilograms to pounds?
Maru [420]

Answer:  (1 Kilogram = 2.20462 pounds) . There are 2.2046226218 lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2.205 for an approximate result. 1 kilogram is also equal to 2 lb and 3.27396195 oz. Working out a rough estimate in your head for converting to pounds and ounces may be tricky - remember that there are 16 ounces in a pound.

Question#31-32, I not sure and don’t know how to do,
LUCKY_DIMON [66]

Answer: 30. 7 moles SO3

31. 3 moles SO2 and 3 moles SO3

Explanation: To solve for this problem use the mole ratio of the substances involved in the reaction.

Solution for number 30:

3.5 moles O2 x 2 moles SO3 / 1 mole O2

= 7 moles SO3

31. 192 g SO2 x 1 mole SO2 / 64 g/ mol SO2

= 3 moles SO2

3 moles SO2 x 2 moles SO3 / 2 moles SO2

= 3 moles SO3
