What is the chemical formula for chlorophyll?
It is difficult to show the structural formula of C6H11ClThere are six carbons in a hexagonal ring, each carbon has two hydrogens except one carbon has one hydrogen and a chlorine to make its third and fourth bonds.
Is iodine larger than glucose?
iodine cells are smaller then glucose ------- I would take exception to the first answer. Iodine is clearly smaller because it exists as a diatomic molecule I2 while glucose is a molecule of 24 atoms, having the chemical formula C6H12O6.
What are the first and last elements in a spinal reflex?
The first element in a spinal reflex is the sensory receptor, which detects a stimulus. The last element is the effector, which carries out a response to the stimulus.
What scientist were first to model DNA?
James Watson and Francis Crick are credited with the first accurate model of DNA's molecular structure in 1953. Their double helix model of DNA paved the way for groundbreaking discoveries in genetics and molecular biology.
How do you know when the different kinds of organisms first appeared on earth?
Scientists use a combination of fossil evidence, geological layers, and molecular dating techniques to estimate when different kinds of organisms first appeared on Earth. The fossil record provides insights into the past diversity of life, while molecular dating helps establish evolutionary timelines based on genetic differences among living organisms.
In a formula for an ionic compound which element comes first?
The element that forms the cation (positive ion) comes first in the formula for an ionic compound.
How does on determine a molecular formula from the empirical formula?
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.
To name a binary molecular compound you add the suffix -ide to the more ionic of the two elements?
That is partially correct. When naming a binary molecular compound, you add the suffix -ide to the second element in the formula, regardless of its ionic nature. The more electronegative element is usually listed first in the compound formula.

How can one effectively read a molecular formula?
To effectively read a molecular formula, one should first identify the elements present and their respective symbols. Next, determine the number of atoms of each element by the subscripts following the element symbols. Finally, consider any parentheses or coefficients that may affect the overall structure of the molecule.
What is the molecular formula of a compound if the weight is of a unit of the compound is 120 and the empirical formula is C3H4?
To find the molecular formula, you first need to calculate the empirical formula mass of C3H4. C3H4 has an empirical formula weight of 40 g/mol. If the molecular weight is 120 g/mol, then the molecular formula would be 3 times the empirical formula, so the molecular formula would be C9H12.
How do you find the molecular formula for MSG?
To find the molecular formula for MSG (monosodium glutamate), you need to first determine the number of atoms of each element present in the compound. Glutamate consists of carbon, hydrogen, nitrogen, and oxygen atoms, with one sodium atom added in the form of monosodium. By counting the atoms and simplifying the ratio to the simplest form, you can determine the molecular formula for MSG, which is C5H8NNaO4.
Which symbol comes first in a chemical formula?
This depends on the type of compound. For metallic compounds, the metal comes first. For nonmetallic inorganic compounds the more electropositive element comes first. For MOST organic compounds, carbon comes first.
What steps are used to convert an empirical formula into a molecular formula?
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
What are the steps in writing a molecular compound?
First U have to write the symbols of elements that form the compound, forexample if we want to write the chemical formula of magnesium chloride:1. Mg Cl2. we have to write the valence of each element below itMg Cl2 1then, we switch the valences of each oneso, the chemical formula is going to be:MgCl2
Determine the molecular formula of a compound if its empirical formula is C2H6O and its molar mass is 138g?
Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula. x ( MM of empirical formula ) = MM of molecular formula MM of empirical formula = 12(2) + 1(6) + 16 = 46 MM of molecular formula = 138 46x = 138 x= 138 / 46 x=3 Therefore, the molecular formula is 3(C2H6O) that is C6H18O3
What is the formula for binary molecular compound?
The formula for a binary molecular compound consists of the symbols of the elements present in the compound, with subscripts indicating the ratio in which they combine. The element with the lower electronegativity is typically listed first, followed by the element with higher electronegativity. The subscripts in the formula indicate the number of atoms of each element in the compound.
