Which 1.0 M solution has the lowest pH?
melamori03 [73]
The solution with the lowest pH would mean that it is an acid, specifically a strong acid which completely dissociates into ions in aqueous solution. Among the choices listed above, I think the correct answer is option D. It is nitric acid that will have the lowest pH because it is the only strong acid in the group.

If the concentration of a sugar solution is lower outside the cell than inside the cell which will happen by osmosis?. A.Sugar w
lys-0071 [83]

Answer: option C.Water will move into the cell

Explanation:

1) Start by analyzing what the statement means in terms of relative concentrations:

------------------------ | inside the cell ------------ | outside the cell |

sugar --------------- | higher ----------------------- | lower ------------- |

water -------------- | lower ------------------------- | higher ------------ |

2) Osmosis is the process where a barrier (the celll membrane) permits the pass of some component and not others.

The component that can pass is that whose particles are smaller. Sugar molecules (the solute) are bigger than water molecules (the solvent), so sugar molecules cannot pass the cell membrane. Only water can.

3) The driviing force for the motion of water molecules is called diffusion. The diffusion occurs from higher concentrations to lower concentrations.

Hence, the water molecules will from outside the outiside the cell, where they have the greater concentration, toward the inside of the cell, where water hasa the lower concentration.

As result, the water will move into the cell, which is the option C.

In an experiment, students were given an unknown mineral. The unknown mineral was placed in 150 ml of water. Once in the water,
Dahasolnce [82]

Answer:

<h2>15 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

But from the question

volume = final volume of water - initial volume of water

volume = 165 - 150 = 15 mL

We have

density =  \frac{225}{15}  = 15 \\

We have the final answer as

<h3>15 g/mL</h3>

Hope this helps you
