What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.
What are the four elements that make up over 95 percent of the body in most of energy?
The four elements that make up over 95 percent of the human body are oxygen, carbon, hydrogen, and nitrogen. These elements are fundamental in forming essential molecules like proteins, carbohydrates, and fats, which are crucial for energy production and bodily functions.
How many elements are in a water molecule?
Two different types: Two hydrogen atoms and one oxygen atom.
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of water molecule?
An oxygen atom has 6 electrons in its outermost energy level. When it shares electrons with two hydrogen atoms to form a water molecule, oxygen will share 2 of its electrons with each hydrogen atom, allowing each hydrogen to complete its outermost energy level with 2 electrons. This results in oxygen having a full outermost energy level with 8 electrons.
How can electrolysis be used to produce hydrogen?
Electrolysis can be used to produce hydrogen by passing an electric current through water, splitting it into hydrogen and oxygen gases. This process involves using an electrolyzer, which contains electrodes and an electrolyte solution, to separate the hydrogen and oxygen molecules.
What is the percent composition of acetate?
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.
What is the precent composition of hydrogen in water?
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
What is the percent composition of ammonium nitrate?
Ammonium nitrate has a percent composition of approximately 35% nitrogen and 69.3% oxygen. The remaining percentage is made up of hydrogen and ammonium ions.
What is the percent composition of each element in beryllium hydrogen carbonate?
BeCO3 Oxygen - 69,56 %; Carbon - 17,39 %; Beryllium - 13,04 %.
What is the percent composition of cysteine?
The percent composition of cysteine (C3H7NO2S) is: - C: 29,75 % - O: 26,43 % - H: 5,83 % - N: 11,57 % - S: 26,42 %
What contains 58.3 percent oxygen 37.5 percent carbon and 4.2 percent hydrogen?
This composition matches that of sucrose, which is a type of sugar commonly found in fruits and vegetables.
Is oxygen not the abundant element in the universe?
No, it is hydrogen.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
How does the composition of a mixture of hydrogen and oxygen differ from the composition containing hydrogen and oxygen?
A mixture of hydrogen and oxygen would consist of separate H2 and O2 molecules. The hydrogen and oxygen would retain their own properties. The most common compound of hydrogen and oxygen is water. In it the two elements are combined into molecules of H2O, which has its own set of properties distinct from those of hydrogen or oxygen.
What is the percent composition of C8H8O3?
To find the percent composition of C8H8O3, you will need to calculate the molar mass of the compound. C8H8O3 has a molar mass of 152 g/mol. To find the percent composition of each element: Carbon (C): (8 mol C / 152 g) * 100 = 52.6% Hydrogen (H): (8 mol H / 152 g) * 100 = 5.3% Oxygen (O): (3 mol O / 152 g) * 100 = 19.7% Therefore, the percent composition of C8H8O3 is approximately 52.6% carbon, 5.3% hydrogen, and 19.7% oxygen.
Evidence that supports the law of constant composition?
A piece of evidence that is commonly used to prove the law of constant composition is that any sample of water is 88. 71 percent oxygen and 11. 19 percent hydrogen. It was formulated by Joseph Proust.
What is the molecular composition of water?
H20 is the molecular composition of water. Two hydrogen atoms and one oxygen atom. The hydrogen atoms are pulled to the oxygen atom through forces called hydrogen bonding.
