What information is needed to determine the orientation of the orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
What information about a mineral is needed to determine its density?
volume and mass
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
What information about a mineral or rock is needed to determine its density?
To determine the density of an object, you need its mass and volume. If the object is oddly shaped, you can determine its volume by measuring the volume of water displaced when thee object is submerged in a container of water.
What is needed to determine the orientation of an orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
The number of atoms of one element in the compound
How do you find x and y?
More information is needed to determine x and y. Do you have a point on a graph? Are you given a formula?
What information is needed to determine the orientation of an orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
What information is needed to determine the orientation of the orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
What information is needed to determine the size of an orbital?
n is needed to determine the size. As n gets bigger, so does the atom.
What information about a mineral is needed to determine its density?
volume and mass
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
Which two pieces of information about a country are needed to determine its determine its population density?
population and life expectancy
What two pieces of information are needed to determine the ratio of elements in a compound?
i
What information is needed for a mortgage calculator?
"The information that is needed for a mortgage calculator will be income and source of other income, debt and other assets that can be used to determine payments."
How many grams of oxygen are needed for the complete combustion of the butane in the lighter?
The variables for the formula are incomplete. You would need to know how many grams of butane are put out by the lighter. The molecular weight of butane is 58.12 g/mol, which is also needed to complete the formula.
