What else can I help you with?
Which one of these represents an atom-O O2 O3 H2?
O2 represents a molecule of oxygen gas, consisting of two oxygen atoms bonded together. O and H2 represent single atoms of oxygen and hydrogen, respectively. O3 represents a molecule of ozone, consisting of three oxygen atoms bonded together.
What could be in water from a lake?
The Element H2 (Hydrogen) And The Element O (Oxygen)
What is the chemical formula for oxygen and hydrogen?
Chemical Name = Oxygen Chemical Symbol = O There is no chemical formula for elements.
What is the chemical balance for Hydrogen and oxygen gas react to form water?
h2 o
What property does water have?
It is a compound made from 2 Hydrogen(H2) and Oxygen (O). Together that makes H2O!
Why do they call it h20?
because water contains 2 hydrogen atoms (H2) and 1 oxygen atom (O).
Is H2O a molecular covalent product?
no because h2 is 2 parts of hydrogen and o is one part oxygen
How many atoms in a water molucle?
There are 3 atoms in a molecule of water, 2 hydrogen (H) atoms and 1 oxygen atom (O). H2 O
Would you expect it to be harder to remove an electron from Na or O?
It would be easier to remove an electron from Na compared to O. Sodium (Na) has a smaller effective nuclear charge and a larger atomic radius compared to oxygen (O), making its valence electron easier to remove. Oxygen has a higher electronegativity and a stronger pull on its electrons, making it harder to remove an electron from O.
How does the formula for water tell you that there is only one oxygen atom in a water molecule?
Water is H2O, so it contains two hydrogen atoms (H2) and one oxygen atom (O).
What mass of H2O can be made from 24gO oxygen and 16g H2?
The molar mass of O is 16 g/mol and H is 1 g/mol. From the given masses, we calculate moles: 24 g O / 16 g/mol = 1.5 mol O and 16 g H2 / (2 g/mol) = 8 mol H2. The balanced chemical equation for the formation of water from hydrogen and oxygen is 2H2 + O2 -> 2H2O, so we need twice as many moles of H2 as O2. Hence, 1.5 mol O2 would require 3 mol H2, which is 3/2 * (2 g H2O/mol) = 3 g H2O.
What are the elements of h2so4?
H2 - 2 hydrogen atoms SO4 - 1 sulfur atom, 4 oxygen atoms
