What gives you the most information a molecular or a structural formula?
A structural formula gives more information because it shows not only the types and numbers of atoms in a molecule, but also how they are connected to each other. Molecular formulas only provide the types and numbers of atoms in a molecule.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 2:1. To find the empirical formula, divide the moles of each element by the smallest number of moles, which is 0.059 mol for hydrogen. This gives a ratio of 1:0.5 for hydrogen and oxygen, which simplifies to the empirical formula H2O. To find the molecular formula, calculate the molecular mass of H2O (18 g/mol) and divide the given molecular mass (34 g/mol) by the empirical formula mass to get the multiplier of 2. So, the molecular formula of the compound is H2O2.
What elements make up water?
Water is made up of two hydrogen atoms bonded to one oxygen atom, resulting in the chemical formula H2O. This arrangement gives water its unique properties such as a high specific heat capacity, cohesion, and universal solvent capabilities.
How many moles of hydrogen atoms are present in 2 moles of benzene?
2 moles of benzene gives 12 moles of hydrogen atoms since benzene is C6H6
What is the molecular mass of vitamin K C31H46O2?
Atomic mass for carbon,hydrogen and oxygen are 12,1 and 16 respectively.since the molecular formula of vitamin K is C31H46O2, then the respective atomic mass for each element are substituted in the molecular formula. That is,the total number of carbon present is 12 multiplied by 31 which gives 372,the total number of hydrogen present is 1 multiplied by 46 which gives 46,and finally the total number of oxygen present is 16 multiplied by 2 which gives 32.The total addition of all these gives the molecular mass 450g. answer 450.7
When aluminum metal is added to hydrobromic acid what kind of change occurs?
A chemical change occurs when aluminum metal is added to hydrobromic acid. This reaction produces aluminum bromide and hydrogen gas as products. The aluminum metal reacts with the hydrobromic acid to form aluminum bromide and hydrogen gas, which is a common example of a single replacement reaction.
What atoms does each molecule h2o contain?
two hydrogen and 1 oxygen, the chemical formula is H2O which gives you the answer
What is the formula for potassium plus water yields potassium hydroxide plus hydrogen?
2H+2H2O gives 2KOH+H2
Is a brutto formula the molecular formula?
No, a brutto formula typically refers to the empirical formula of a compound, which gives the simplest whole-number ratio of atoms in a compound. The molecular formula, on the other hand, gives the exact number of each type of atom present in a molecule.
How do you show that propane contains hydrogen?
Propane is a hydrocarbon compound composed of carbon and hydrogen atoms. Its chemical formula is C3H8, indicating that it contains hydrogen atoms. The presence of hydrogen in propane can be confirmed through various analytical techniques such as elemental analysis or spectroscopic analysis.
What atom does each molecule of H2O contain?
two hydrogen and 1 oxygen, the chemical formula is H2O which gives you the answer
What is the formula of the hydride formed by lithium?
The formula of the hydride formed by lithium is LiH. In this compound, lithium gives up one electron to form a Li+ ion, and hydrogen accepts the electron to form an H- ion, resulting in a stable ionic compound with a 1:1 ratio of lithium to hydrogen.
Is the formula for methane both a molecular and an empirical formula?
Yes, the formula for methane (CH4) is both a molecular formula and an empirical formula. The molecular formula shows the actual number of each atom in a molecule (4 hydrogen atoms and 1 carbon atom), while the empirical formula gives the simplest whole-number ratio of atoms in a compound (CH4).
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
To find the empirical formula, we first need to convert the mass of CO2 and H2O to moles. From the molar ratios in the products, we find the moles of carbon and hydrogen present. Then, we determine the ratio of carbon to hydrogen atoms, giving the empirical formula as C7H8.
How many hydrogen atoms are there in an alkane molecule with 10 carbon atoms?
Formula for alkanes:Number of H = 2 * number of C + 2So, using this formula, H = 2 * 10 + 2, which gives 22
What is hydrogen called when it gives up electrons?
When a hydrogen atom loses an electron, it is simply a proton.
What gives you the most information a molecular or a structural formula?
A structural formula gives more information because it shows not only the types and numbers of atoms in a molecule, but also how they are connected to each other. Molecular formulas only provide the types and numbers of atoms in a molecule.
