What is the pKa of HCHO2?
The pKa of: NH4(+) = 9.4 NH3 = 38 NH2(-) = EXTREMELY HIGH (due to the the instability of compounds like NH(2-) and N(3-) the pKa values are not currently known -- they really aren't around for long enough to get an accurate pka value. There may be experimental values in the literature somewhere, but they are likely not going to be the same from source to source!)
What is the chemical formula for an a alkane with 42 carbons?
The chemical formula for an alkane with 42 carbons is C42H86. It follows the general formula CnH2n+2, where n represents the number of carbon atoms in the alkane chain.
What is formula of berrylate?
There is no standard chemical formula for "berrylate" as it is not a recognized chemical compound or ion. It may refer to a hypothetical or obscure compound that is not commonly known in chemistry.
What is the molecular formula of CH2 with molar mass about 42 g?
The molar mass of a compound is the sum of the molar masses of its individual atoms. With a molar mass of approximately 42 g, a molecular formula of C2H4 (ethene) fits the criteria, where two carbon atoms (212 g/mol) and four hydrogen atoms (41 g/mol) yield a total molar mass close to 42 g/mol.
How many hydrogens are present on an alkane with 20 carbons?
An alkane with 20 carbons will have 42 hydrogens. This can be calculated using the formula 2n+2, where n is the number of carbons (C) in the alkane. So for an alkane with 20 carbons, the number of hydrogens would be 2(20) + 2 = 42.
What is the Importance of Henderson-Hasselbalch equation in the study of buffers?
The Henderson-Hasselbalch equation is important in the study of buffers because it relates the pH of a buffer solution to its acid dissociation constant (Ka) and the concentration of the acid and its conjugate base. This equation allows scientists to predict how changes in concentration will affect the pH of a buffer solution, making it a valuable tool in designing and understanding buffer systems.
What is the area of a triangle if the base is 12Cm and height 7Cm?
The formula to calculate the area of a triangle is 1/2 * base * height. In this case, the base is 12 cm and the height is 7 cm. Plugging these values into the formula, we get 1/2 * 12 cm * 7 cm = 42 square cm. Therefore, the area of the triangle is 42 square cm.
If a triangle has an area of forty two square inches and a base of six inches what is its height?
Formula: Area of triangle= 1/2 * base * height Therefore 42 (area of triangle) = 1/2 * 6 (base) * height 42 = 3 * height 42/3 = (3 * height)/3 14 = height Therefore, the height of triangle is 14 inches

Formula for the volume of a cylinder?
V=area of a base times the height ie: 3.14(42)(15)=753.6 Volume=pi x radius sqaured x height
What is the chemical formula for an a alkane with 42 carbons?
The chemical formula for an alkane with 42 carbons is C42H86. It follows the general formula CnH2n+2, where n represents the number of carbon atoms in the alkane chain.
What is 42 equals 60 percent of?
Base = 70 Percentage = 42 Rate = 60% or 0.6 Base = Percentage/Rate = 42/0.6 = 70
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42?
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
What is the area of a triangle with a base of 14 cm and a height of 6 cm?
The area of a triangle is calculated using the formula A = 0.5 * base * height. Plugging in the given values, we get A = 0.5 * 14 cm * 6 cm = 42 square cm. Therefore, the area of the triangle is 42 square cm.
What is the measure of the vertex angle of an isosceles triangle if a base angle is 42?
180 - twice 42
