Paraphrasing and summarizing
<u>Analysing the Question:</u>
We are given a 250 mL solution of 0.5M K₂Cr₂O₇
Which means that we have:
0.5 Mole in 1L of the solution
0.125 moles in 250 mL of the solution <em>[dividing both the numbers by 4]</em>
<em />
<u>Mass of K₂Cr₂O₇ in the given solution:</u>
Molar mass of K₂Cr₂O₇(Potassium Dichromate) = 194 g/mol
<em>we know that we have 0.125 moles in the 250 mL solution provided</em>
Mass = Number of moles * Molar mass
Mass = 0.125 * 194
Mass = 36.75 grams
Answer:
62.15 m (squared)
Explanation:
We know that the Area of the square is 5.5 x 4= 22
so 90 degree to 30 degree is divide by 3
so u divide 22 by 3 and get 7.3 wich is the semi circle thing
now 7.3 x 5.5 = 40.15
22 + 40.15 = 62.15 m (squared)
Look im not really sure but I think this is the answer

112.2 milliliters volume of water will drip into the bucket in 44 minutes.
<h3>What is volume?</h3>
How much space an object or substance takes up. • Measured in cubic meters (m3), liters (L) & milliliters (mL).
Total drop = Drops per minute X time
= 51 drops per minute X 44 minutes
=2244 drop
Volume of water will drip into the bucket in 44 minutes
=Total drop X Volume of each drop
=0.050 milliliters X 2244 drop
=112.2 milliliters
Hence, 112.2 milliliters volume of water will drip into the bucket in 44 minutes.

Answer:
Double replacement reaction
Explanation:
This is what is known as a double replacement reaction. The two parts of each molecule separate and recombine to form two new compounds. For instance, 
separates into 
and 
, while 
separates into 
and 
, and then they recombine with the other compound.
Hope this helps!
