If C7HxO2 is a carbohydrate what is the value of x?
Well, isn't that a happy little question! Carbohydrates have a general formula of Cx(H2O)y, where x and y are the number of carbon and water molecules, respectively. Since the formula you provided, C7HxO2, is close to the general formula, we can see that x should be 12 to match the ratio of carbon and water molecules in a carbohydrate. Keep up the great work, my friend!
Is a mole 6.02214 times ten to the 23rd power?
A mole is that number of molecular units of a substance. The number is called the Avogadro constant, or Avogadro's number. (It is defined as the no. of atoms in 12 grams of carbon-12). For example, Iron has the chemical formula Fe. So a mole of iron is (Avogadro's no.) Fe atoms. Water has the formula H2O. A mole of water, then, is (Avogadro's no.) H2O molecules.
How many molecules are in 1 mole of Glucose?
There are 6.022 x 10^23 molecules in 1 mole of glucose. This number is known as Avogadro's number and represents the number of units (atoms, molecules, etc.) in one mole of a substance.
What forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine?
The forensic scientist can assume that the number of adenine molecules in the DNA sample is equal to the number of thymine molecules, as adenine always pairs with thymine in DNA. This is known as Chargaff's rule. By determining the number of thymine molecules, the scientist can indirectly infer the number of adenine molecules present in the DNA sample.
4 molecules of an enzyme and 60000 molecules of substrate are taken all substrate molecules are converted into products in 5 minutes calculate turnover number of enzyme?
Assuming that the turnover number is 5000 per second, which you did not specify, than the number of molecules that can be reached by the enzyme in 5 minutes is just this:5 minutes * 60 seconds/minute * 5000 turnover/second = 150,000 turnoversThis is because 1 turnover counts as one molecule reached by the enzyme.If instead the turnover number was 5000 per minute, then it would be:5 minutes * 5000 turnovers/minute = 25,000 turnovers.If it was 5000 per hour, then it would be:5 minutes * 1 hour/60 minutes * 5000 turnovers/hour = 416.7 turnovers.
The figure that gives the number of identical molecules in a formula is called what?
coefficient
What in a formula tell the number of molecules?
2t of course it does
How many elements of unsaturation do molecules with a molecular formula of c6h6cl6 have?
Molecules with a molecular formula of C6H6Cl6 have 7 elements of unsaturation. This is calculated using the formula: E = 1 + (number of carbons) - (number of hydrogens) / 2 + (number of nitrogens) + (number of halogens).
What does a n mean in a formula?
This is an unknown number of atoms or molecules.
What is the formula for a quadrangle?
Number of vertices in the plane figure = 4.
What part of the chemical formula indicates the number of atoms or molecules involved?
coefficients
What formula gives the lowest whole-number ratio of moles of atoms in a mole of molecules?
The formula that gives the lowest whole-number ratio of moles of atoms in a mole of molecules is the empirical formula. This formula represents the simplest whole-number ratio of atoms in a compound. It is determined based on the elemental composition of the compound.
What is the formula to figure out how many diagnols there are in a shape?
Formula: 0.5*(n2-3n) where n is the number of sides
What part of the chemical formula indicates the number of molecules of atoms involved?
coefficients
180 g of glucose and 342 g of sucrose have same number of molecules but different number of atoms. Explain?
They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11
What is the number placed in front of a chemical formula that tells how many atoms or molecules there are in the formula?
That is called a coefficient in a chemical equation. It indicates the number of molecules or units of a substance involved in a reaction.
What is the name of a number in front of a chemical formula in an equation called?
This is the number of molecules or atoms involved in the reaction.
