Answer: The precipitate formed is 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
Answer:
Explanation:
The unbalanced nuclear equation is
Let's write the question mark as a nuclear symbol.
The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
98 = 0 + A, so A = 98 - 0 = 98, and
38 = -1 + Z, so Z = 38 + 1 = 39
Then, your nuclear equation becomes
Element 39 is yttrium, so the balanced nuclear equation is
D. the reflection of each concave lens makes the object appear larger
First lets define upwelling
Upwelling- a rising of seawater, magma, or other liquid
In this case, you would be looking at a river, lake, ocean, or other body of water good for fishing.
You'd want to look for a place with upwelling because when there is a rise of water, the sea creatures within it will rise too. So the fish in the bottom of a lake for example would be brought up to the surface of the water or near the surface which is where your fishing rod is trying to grab the fish.
