Answer:
A typical carbon carbon bond requires 348 kJmol to break What is the longest from ... wavelength (in nm) of radiation with enough energy to break carbon-carbon bonds? ... and radiation with shorter wavelengths can damage biological molecules because they carry enough energy to break bonds within the molecules.
Explanation:
Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because these kinds of radiation carry enough energy to break bonds within the molecules. A typical carbon -carbon bond requires 348 kJ/mol to break.
Answer:
15 oxygens
Explanation:
Given the partially balanced reaction:
The subscripts (small number to the right of each element symbol) are the number of atoms of the element within each compound/molecule, and the coefficients (numbers in front of each compound) represent the number of that molecule involved in one full reaction (if the equation were balanced).
The product side of the reaction is on the right of the arrow.
To determine the total number of Oxygens on the product side, we need to identify how many Oxygens are in each molecule (the subscript on the Oxygen), and then multiply times the number of that molecule that would be involved (Coefficient of the compound containing Oxygen). There are multiple compounds on the right side of the equation that contain Oxygen, so we'll need to add together the number of Oxygens each part contributes.
It keeps the plant upright, and it provides nutrients
Answer:
a.
b.
c.
Explanation:
a. To calculate the number of moles of NaOH we need the following definition of molarity:
b. As we have a diprotic acid, it means that when the second equivalence point is reached, two moles of NaOH have reacted by one mol of acid, therefore the relation we use to determine the moles of acid is:
c. Finally, we determine the molar mass as follows:
B. A solid forms when two liquids are mixed
