Two different mixtures that are dissolving sugar and salt are described below: Mixture 1: Large chunks of sugar and salt are put into a pot of water and slowly stirred.
Mixture 2: Small grains of sugar and salt are stirred into a hot pot of water.

Which statement is true about dissolving?

A The two mixtures will dissolve the sugar and salt at the same rate.
B Mixture 1 will dissolve the sugar and salt at a faster rate.
C Mixture 2 will dissolve the sugar and salt at a faster rate.
D Mixture 2 will not dissolve the sugar and salt at all.

options c

Explanation:

C Mixture 2 will dissolve the sugar and salt at a faster rate.

the answer is C

Explanation:

Because hot water makes sugar and salt dissolve faster also smaller chunks dissolve faster rather than large chunks in room temperature and is slowly stirred.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
