Answer:

The correct answer is option is c.

Explanation:

Mass is defined as quantity of the matter contained by the body irrespective of its volume or any other forces acting on it.

Mass of substance Robert has = $m_1$ = 4 grams

Mass of same substance Jill has = $m_2$ 10 grams

4 grams < 10 grams

$m_1$

Sample of Jill is more in weight that the weight of the substance of Robert.

a. Calculate the pH of a solution that has [H3O+]= 4.3 x 10-5 M. b. Is the solution acidic or basic? How do you know?

Luda [366]

Answer:

* $pH=4.37$

* The solution is acidic since the pH is below 7.

Explanation:

Hello,

In this case, we can mathematically define the pH by:

$pH=-log([H_3O^+])$

Thus, for the given hydronium concentration we simply compute the pH:

$pH=-log(4.3x10^{-5})=4.37$

Thereby, we conclude the solution is acidic due to the fact that the pH is below 7 which is the neutral point and above it the solutions are basic.

Regards.

Be(OH)2 is solid why?

pickupchik [31]

Answer:

no it's not solid rather it's an aqueous

Explanation:

B/c Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water.
