Which is a property of every homogeneous mixture?

Answers

Answer 1

Answer:

Answer:

Every homogeneous mixture is uniform in nature.

Explanation:

One of the most interesting facts about homogeneous mixtures is that, in a sense, there's no real distinction. The mixture is uniform in nature.

Conversely, at a large enough scale everything in the universe is homogeneous, because it becomes impossible to differentiate components.

Answer 2

Answer: The answer is:

Each part of the mixture has the same appearance would be a property of a homogeneous mixture. A homogeneous mixture has a uniform composition and every part of the solution has the same properties.

Hope this helps :D

What is the word equation for molecules of magnesium reacting with molecules of oxygen to produce molecules of magnesium oxide?magnesium + magnesium oxide = oxygen
magnesium + oxygen =magnesium oxide
magnesium oxide = magnesium
magnesium + oxygen magnesium + oxygen

Answers

Answer: magnesium + oxygen =magnesium oxide

Explanation: When Magnesium reacts with the molecules of oxygen , Magnesium oxide is produced.

Mg (s) + O (g) → MgO (s)

In this equation, both magnesium and oxygen are present in its elemental state.

Magnesium is present in solid form and oxygen is present in gaseous form.

The Bonding between the Magnesium and the oxygen is purely IONIC bonding as Magnesium loses its 2 valence electrons to complete its octet and oxygen gains its electrons to make its electron count 8 in the valence shell.

Answer: (B) Magnesium + oxygen =magnesium oxide

calculate the mass required to prepare 2.5 L of 1.0 M NaOH solution. Given that the molar mass for NaOH is 40 g/mol.

Answers

Answer:

$100\; \rm g$ of ${\rm NaOH}\; (s)$ would be required.

Explanation:

The quantity of solute in a solution of concentration $c$ and volume $V$ would be $n = c \cdot V$ .

It is given that volume $V = 2.5\; \rm L$ for the solution in this question. It is also given that the concentration of the $\rm NaOH$ solute in this solution is $c = 1.0\; \rm M$ , which is the equivalent to $c = 1.0\; \rm mol \cdot L^(-1)$ .

Apply the equation $n = c \cdot V$ to find the quantity of $\rm NaOH$ in this solution:

$\begin{aligned}n &= c \cdot V \n &= 1.0\; \rm mol \cdot L^(-1) * 2.5\; \rm L \n &= 2.5\; \rm mol\end{aligned}$ .

Multiply the quantity $n$ of $\rm NaOH$ in this solution with the formula mass $M$ of ${\rm NaOH}\!$ to find the corresponding mass:

$\begin{aligned}m &= n \cdot M \n &= 2.5\; \rm mol * 40\; \rm g \cdot mol^(-1) \n &= 100\; \rm g\end{aligned}$ .

Thus, this solution would contain $100\; \rm g$ of ${\rm NaOH}$ .

It would thus take $100\; \rm g$ of ${\rm NaOH}$ to prepare this solution.

Answer:

The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g

Explanation:

We do this by preparing the equation:

Mass = concentration (mol/L) x volume (L) x Molar mass

Mass = 1.0 M x 2.5 L x 40 g/mol

Mass = 100 g
