It is estimated that about 1 ft of snow is equal to 1 inch of rain.
Converting inch to cm
1 inch=2.54 cm
Thus, 1 cm=0.393 inch
2.5 cm of rain will be 0.984 inch
now 1 inch of rain is equal to 1 ft of snow, thus, 0.983 inch of rain will be:
0.983 inch of rain=0.983 ft of snow.
Converting ft to cm:
1 ft =30.48 cm
Thus,
0.983 ft= 29.96 cm
Thus, 2.5 cm of rain= 29.96 cm of snow.
The answer is replication. The process of replication allows cells to reproduce and repair body tissue.
The chemical formula for calcium hydroxide is Ca(OH)₂ and that of nitric acid is HNO₃. By these chemical formula it can be deduced that the number of equivalents per mole of Ca(OH)₂ is 2 because of 2 OH⁻ and for HNO₃ is 1 because of H⁺.
For the neutralization reaction, the number of equivalents should be equal.
V₁n₁ = V₂n₂
Substituting the known values and with the incorporation of the concept above,
(V₁)(0.0250 mol/L)(2 equivalents/mol) = (33.50 mL)(0.020 mol/L)(1 equivalent/mol)
V₁ = 13.4 mL
Hence, the volume of calcium hydroxide needed is approximately equal to 13.4 mL.
A) 120 mm
B) 127 mm
C) 914.4 mm
D) 1000 mm
E) 3048 mm
Substances are chemically combined and cannot be separated by normal physical means. Mixtures, however, are simply physically combined and can be separated into their component parts.
