<h2>Answer: Mg²⁺ & N³⁻</h2>

<h3>Explanation:</h3>

Magnesium (group IIA) loses two electrons to become a cation. This is the most energetically favorable way for Magnesium to obtain a valence electron that is stable (octet). When an atom loses electrons it has a positive charge that matches the number of electrons lost.

Nitrogen (group VA) gains three electrons to become an anion. This is the most energetically favorable way for Nitrogen to obtain a valence electron that is stable (octet). When an atom gains electrons it has a negative charge that matches the number of electrons gained.

How many L of 3.0 M H2SO4 solution can be prepared by using 100.0 mL OF 18 M H2SO4?

max2010maxim [7]

Answer: A volume of 600 mL of 3.0 M $H_{2}SO_{4}$ solution can be prepared by using 100.0 mL OF 18 M $H_{2}SO_{4}$ .

Explanation:

Given: $V_{1}$ = ?, $M_{1} = 3.0 M\\$

$V_{2} = 100.0 mL$ , $M_{2} = 18 M$

Formula used to calculate the volume is as follows.

$M_{1}V_{1} = M_{2}V_{2}$

Substitute the values into above formula as follows.

$M_{1}V_{1} = M_{2}V_{2}\\3.0 M \times V_{1} = 18 M \times 100.0 mL\\V_{1} = \frac{18 M \times 100.0 mL}{3.0M}\\= 600 mL$

Thus, we can conclude that a volume of 600 mL of 3.0 M $H_{2}SO_{4}$ solution can be prepared by using 100.0 mL OF 18 M $H_{2}SO_{4}$ .

What is the difference between a heterogenous and a homogenous mixture?

Brrunno [24]

Answer:

There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
