Particles that are smaller and have ____ generally dissolve faster.(1 point)
Answers
The given quantity of any substance is an important aspect of it merging with other substances. The smaller the particles the less is the surface area exposure.
- The fine particles of sugar are easily dissolved as compared to a packet of sugar dissolves more quickly than the cube. Thus it deepens the solute state. The temperature and amount of steering.
Thus smaller particles have less surface area.

Answer:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Hi,
Here is the step by step procedure to find the answer:
First of all we need to find out the molecular mass of H2SO4
- H = 1.008
- S = 32.065
- O = 16
So mass of H2 SO4 will be : (2x1.008) + (1x32.065) + (16x4)
= 98.081 g/mole
This shows that 1 mole of H2So4 contain 98 grams.
Now we need to fin out the no. of moles of H2SO4 in 250 grams
250 g x (1mole/250g)
= 2.5489 moles
Now we need to find out how many moles of oxygen are present in 2.5489 moles of H2SO4.
So, as mentioned in the formula of H2SO4, we can see that four moles of oxygen are present in one mole of H2SO4
It means that 2.5489 moles of H2SO4 contain:
2.5489 x4
= 10.19565 moles of oxygen
Now, it is very simple to determine the mass of 10.19565 moles of oxygen by using the formula:
no. of mole= mass/molar mass
10.19565 moles= X/ 16 g
10.19565 x 16= X
X= 163.13 grams
Therefore, mass of oxygen in 250 g of H2SO4 is 163.13 grams
Hope it help!

According to one acid-base theory, the H2O molecule
(1) accepts H+ ions (3) donate H+ ions
(2) accepts OH- ions (4) donates OH- ions
Answers
The statement, that describes acid-base theory in which the H2O molecule is "accepts ions."
What is an acid-base theory?
An acid is a compound that accepts a pair of electrons. A base is a generator of electron pairs. This is the broadest theory of acids and bases. Water can serve as both an acid and a base in solution, and it can also be both an acid and a base to itself. Water takes hydrogen ions and behaves as a base when coupled with an acid. When water is combined with a base, it gives hydrogen ions and so behaves as an acid. Using the balanced equation, the water molecule acts a acid which accepts the hydrogen ion. to form hydronium ion.
Hence the correct option is 1.
