Use the formula for volume. V = lwh. Plug in the numbers for length,
width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the
volume of the block is 8.0 cm.

Explanation:
Synthesis is the combining of two elements or atoms into a compound/mixture. Decomposition is the breaking down of a compound/mixture into individual atoms or elements. In conclusion, on is the building up of a compund/mixture and one is breaking down.
Answer:
13 chromosomes, meiosis
Explanation:
the sperm cell contributes half of the chromosome in an offspring while the egg cells contributes the other half. Hence, the sperm cell has half of 26, 13. This process is called meiosis. Meiosis is when one cell undergoes cell division twice, thus creating 4 new cells. Each of these 4 new cells have half the amount of chromosomes as the original cell.
Answer:
Explanation:
Hello,
In this case, since we can consider hydrogen gas as an ideal gas, we check the volume-pressure-temperature-mole relationship by using the ideal gas equation:
Whereas we are asked to compute the moles given the temperature in Kelvins, thr pressure in atm and volume in L as shown below:

Answer:
There is 61.538% oxygen in Al2(SO4)3.
Explanation:
Wt Of oxygen in the compound = 12*16 = 192 amu.
Total Wt. Of the compound = 2*12+3*32+12*16 = 312 amu.
Thus, percent of oxygen = Wt of oxygen/total Wt. Of compound *100
= 192/312 * 100=61.538 %
