I think the correct answer is C
I think the best answer would be it electrical conductivity when in aqueous form. A compound having an ionic compound dissociates into ions when in aqueous solution. These ions move freely in the solution and can allow the flow of electricity into the solution.
Answer:
The s stands for the phase of that element or compound. The phase solid is represented by (s). In this problem it is saying solid sodium (Na) is reacting with Bromine (Br) gas to form sodium bromide.
Explanation:
Answer:
Salt's ions and sugar's polar bonds are both attracted to the polar water molecules.
Explanation:
Water is regarded as a universal solvent because of its ability to dissolve more substances than any other liquid. This unique property of water is attributed to its POLAR NATURE. Water is a polar molecule and hence, most if not all polar substances will dissolve in it.
Although salt and sugar are substances that have different types of chemical bonding in their structure but they both dissolve in water. This is because they are both polar substances and hence, their polar charges are attracted to the polar molecules of water. This attraction causes an interaction and subsequently dissolution.
Given data:
Volume of glucose solution = 2.00 L
Density of glucose = 1.15 g/ml = 1.15 * 10^3 g/L
Density of a substance is the amount of that substance present in a unit volume. i.e.
Density = Mass/volume
Therefore, Mass of glucose = Density of glucose solution * Volume of the solution
= 1.15 * 10^3 g/L * 2.00 L = 2.30*10^3 g
Now,
10^3 g = 1 kg
therefore a mass of 2.30*10^3 g = 1 kg * 2.30*10^3 g/10^3 g = 2.30 kg
