Answer 1: The correct answer is b. convergent continental-continental boundary.
A convergent continental-continental boundary refers to a convergent plate boundary where two continental plates meet or come together. When this happens, a forceful collision occurs, and structures like mountains start to form. The Himalaya mountain range is formed as a result of the convergence of the Indian and Eurasian continental plates.
Answer 2: The correct answer is d. convergent oceanic-oceanic boundary.
Volcanic island arcs refers to a curved line of volcanoes formed from the subduction (sinking) of one oceanic plate below another plate. Examples of volcanic island arcs include Japanese Islands and Alaskan Islands.
Answer 3: The correct answer is b.convergent oceanic-continental boundary.
A continental volcanic arc is an arc-shaped chain of volcanoes that form from the subduction of an oceanic plate under a continental plate.
Answer:
A
Explanation:
because your body needs to have an intake in the volume of liquids, and when you sweat it secretes the water from your body
Answer: The mass of sodium bromide dihydrate is 0.208 grams
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml = 250 ml
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the mass of sodium bromide dihydrate is 0.208 grams
The first student treats the starting material which is the 3-oxobutanoic acid with sodium methoxide which is followed by methyl iodide and form compound A. Analysis 1HNMR it shows that this is not the desired material.
Compound A has same 2-methyl-3- oxobutanoate acid as molecular formula.
Explanation:
1) it gives you a visual of what you will be doing
2) you can find more variables when looking at it compared to just thinking of it
3) gives you new insights on what is yet to come
4) allows you to answer some questions and begin testing
