Which law says that hydrogen and oxygen combine in the ratio of 1/8 to form water?

The law of constant proportions
What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas? Answer: The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass.

What are the two compounds formed by hydrogen and oxygen?

Hydrogen and oxygen combine to form two compounds, water and hydrogen peroxide.

What compounds do two hydrogen and one oxygen combine?

water molecule
A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled.

How many hydrogen and oxygen atoms are in a water molecule H2O?

two hydrogen
Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

What is the ratio of hydrogen atoms to oxygen atoms in 2L of water?

The ratio of hydrogen to oxygen atoms in 2L of water is 0.126 H/O.

When hydrogen and oxygen combine to form water the ratio between volume of reactants and products is 2 1 2?

When hydrogen and oxygen combine to form water, the ratio between volume of reactants and products is 2:1:2.

When hydrogen and oxygen combine to form a compound the name of such compound is?

water
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right.

How does hydrogen and oxygen combine into water?

A reaction between them requires energy to break the bonds between the atoms so they can form a new product. Once the bonds break, each hydrogen atom has a +1 positive charge, while each oxygen atom has a -2 negative charge. Two hydrogen atoms bound to one oxygen atom yield water, which is electrically neutral.

What is the percentage of oxygen in water and hydrogen peroxide?

Hydrogen and oxygen combined to form two compounds water and hydrogen peroxide. If the percentage of oxygen is 88.89 in water and 94.12 in hydrogen peroxide. Show that the data support law of multiple proportion? – Quora Hydrogen and oxygen combined to form two compounds water and hydrogen peroxide.

How much hydrogen is formed when hydrogen peroxide decomposes?

A decomposition of a sample of water forms 0.125 g hydrogen to every 1.00 g oxygen. The decomposition of a sample of hydrogen peroxide forms 0.0625 g hydrogen to every 1.00 g oxygen.Show that these results are consistent with the law of multiple proportions.

What is the molecular formula for hydrogen peroxide?

Hydrogen peroxide PubChem CID 784 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula H2O2 Synonyms hydrogen peroxide 7722-84-1 perhydrol ox

What is the stoichiometry of water and hydrogen peroxide?

Water is H2O so the stoichiometry is that one oxygen atom combines with 2 hydrogens whilst hydrogen peroxide is H2O2 so the stoichiometry is that 2 oxygen atom combines with 2 hydrogens. However the “ratios of atoms” in each molecule are 1:2 and 1:1 respectively. so the “proportions” are these.
