Answer:
A. It has a partial negative charge on oxygen and a partial positive charge on hydrogen.
Explanation:
There is an electronegativity difference between O and H atoms. The electronegativity value of O and H are 3.5 and 2.1 respectively. So the electronegativity different of the O-H bond is 3.5- 2.1 = 1.4 thus making the O-H bond polar. O being the more electronegative bond acquires a partial negative charge and H acquires a partial positive charge.

magnesium carbonated reacting with hydrochloric acid will yield magnesium chloride in addition with carbonIVoxide with water
-109 F = -78.333 C = 194.8167 K
A concave meniscus, occurs when the molecules of the liquid are drawn to those of the container. This occurs with water and a glass tube, or cup.
Adhesion is responsible for a meniscus and it has to do with high surface tension
