Answer:

Homogeneous

Explanation:

Homogeneous mixtures are uniform in composition. They have the same proportion of components throughout. Homogeneous mixtures are called solutions. Sugar, paint, alcohol, gold are all examples of homogeneous mixtures because they look the same throughout.

babunello [35]

The order of the solutions from lowest to highest concentration : A, B, C

<h3>Further explanation</h3>

Given

the following solutions

Required

order of increasing concentration

Solution

Molarity shows the number of moles of solute in every 1 liter of solution.

$\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}$

Solution A : 0.5 moles : 2 L solution = 0.25 M

Solution B : 1 moles : 3 L solution = 0.33 M

Solution C : 1.5 moles : 4 L solution = 0.375 M

Do Halogens gain or lose electrons to form ions

Llana [10]

Halogens are among the most reactive of all elements. They have seven valence electrons, so they are very “eager” to gain one electron to have a full outer energy level. So they gain

For the metathesis reaction, K2CO3 + FeCl3, Write the balanced molecular equation. What evidence of reaction occurs in the mixtu

Klio2033 [76]

<u>Answer:</u> A red color precipitate is formed of iron (III) carbonate. The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of potassium carbonate and iron (III) chloride is given as:

$3K_2CO_3(aq.)+2FeCl_3(aq.)\rightarrow Fe_2(CO_3)_3(s)+6KCl(aq.)$

Balanced ionic form of the above equation follows:

$3K^+(aq.)+3CO_3^{2-}(aq.)+2Fe^{3+}(aq.)+6Cl^-(aq.)\rightarrow Fe_2(CO_3)_3(s)+6K^+(aq.)+6Cl^-(aq.)$

As, potassium and chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

Iron (III) carbonate is a red colored solid which gets precipitated out.

The balanced net ionic equation for the above reaction follows:

$2Fe^{3+}(aq.)+3CO_3^{2-}(aq.)\rightarrow Fe_2(CO_3)_3$

Hence, a red color precipitate is formed of iron (III) carbonate. The net ionic equation is written above.

How do I determine the number of atoms in 30.0 g of K

Alika [10]

The number of atoms in 30.0 g of K would be 4.632 x $10^{23}$ atoms.

<h3>Avogadro's number</h3>

1 mole of a substance contains 6.022 x $10^{23}$ atoms.

Mole of 30.0 g of K potassium = 30/39

= 0.7692 moles

Hence, 0.7692 moles of K would contain

0.7692 x 6.022 x $10^{23}$ atoms.

= 4.632 x $10^{23}$ atoms.
