A , because it’s talking about liquid in a container first and answers the question
Mineral water is a type of mixture called a homogeneous solution. This is because there are very small amounts of dissolved minerals in mineral water, such as zinc, iron, copper, magnesium and many others. However, to the eye, mineral water just looks like distilled water.
Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Answer:
an Additional shell
Explanation:
Potassium has an additional energy level when compared to sodium. This is due to an extra shell added. In the periodic table when you go down the group, the atomic radius increases due to increasing energy levels.
The atomic radius mean the distance from the center of the nucleus to the valance shell. it actually describes the size of the atom
