Answer:
<em>The correct option is a) Precipitate: silver sulfate
</em>
<em>
</em>
<em>Net Ionic: 2Ag+ + SO42 →Ag2SO4</em>
Explanation:
When sodium sulfate reacts with silver nitrate, the following reaction occurs:
2AgNO3 + Na2SO4 → Ag2SO4 + 2NaNO3
The NaNO3 is easily soluble in water. However, silver ions form an insoluble solid with SO4. The Ag+ in this compound will be a cation having a positive charge. The SO4- will be an anion having an negative charge.
The table with solubility rules show that the sulfates of Ag+, Ca+, Sr2+, Ba2+, Hg22+ and Pb2+ are insoluble.
Able to be hammered or pressed permanently out of shape without breaking or cracking. An example would be hot metal being shaped.
Group I and Group II have the same number of outermost electrons as you go down each group but the shells increase therefore as you go downward it becomes much easier to remove electrons because of its wide radius however group 7 and 6 have seven and six electrons in their outermost shell respectively. Therefore down the group it is much easier to attract electrons and across the period it is much harder because the number of electrons on the outermost shell increase
The object with dimensions
and with mass 250.6 g will have a density equal to
.
<h3>
<u>Explanation:</u></h3>
<u>Given:</u>
Dimensions of the object =
length = l = 5.54 cm
width = w = 10.6 cm
height = h = 199 cm
Mass of the object = m = 250.6 g
<u>Formula:</u>
The relation between density, mass and volume of any object is given by:

Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,




Density of the object is
