How do you calculate the number of oxygen atoms in 2 NO3 molecules?
To calculate the number of oxygen atoms in 2 NO3 molecules, you first need to determine the total number of oxygen atoms in one molecule of NO3, which is 3 oxygen atoms. Since you have 2 NO3 molecules, you would multiply the number of oxygen atoms in one molecule by the number of molecules, giving you a total of 6 oxygen atoms.
total number of atoms and molecules in 5H2SO4?
To determine the total number of atoms and molecules in 5H2SO4, we first need to break down the chemical formula of sulfuric acid (H2SO4): 1 molecule of H2SO4 contains: 2 atoms of hydrogen (H) 1 atom of sulfur (S) 4 atoms of oxygen (O) Therefore, in 5 molecules of H2SO4, we have: 5 x 2 atoms of hydrogen = 10 hydrogen atoms 5 x 1 atom of sulfur = 5 sulfur atoms 5 x 4 atoms of oxygen = 20 oxygen atoms So, in total, there are 10 hydrogen atoms, 5 sulfur atoms, and 20 oxygen atoms in 5 molecules of H2SO4. Additionally, to find the total number of molecules in 5H2SO4, we simply multiply the coefficient (5) by the number of molecules in the formula (1 H2SO4 molecule) to get: 5 x 1 = 5 molecules of H2SO4. Therefore, in 5H2SO4, there are: 10 hydrogen atoms 5 sulfur atoms 20 oxygen atoms 5 molecules of H2SO4.
What happens to the atoms in water when water boils?
The atoms speed up building up kenetic energy which forces them apart and that is what turns the liquid into a gas
Was Dalton th first person to suggest the idea of atoms?
It was not John Dalton who first suggested the idea of atoms. It was the Greek philosopher and mathematician Democritus who first suggested the existence of atoms.
How many atoms are in 5CH4?
To find the total number of atoms in 5 molecules of CH4, we first calculate the number of atoms in one molecule of CH4. Each molecule of CH4 contains 1 carbon atom and 4 hydrogen atoms, totaling 5 atoms per molecule. Multiplying this by 5 molecules gives us a total of 25 atoms (5 molecules x 5 atoms per molecule) in 5CH4.
What should you look at first when balancing an equation?
Balance complicated molecules with lots of different atoms first. Putting numbers in front of these may mess up other molecules, so use the simpler molecules to adjust these major changes.
Did atoms and molecules first form?
If you when; then at the beginning of time. Somehow, by an explosion or deity or whatever, nothing became something, which became quarks, which became atoms, which became molecules, which became stars, which created density, which caused gravity to exist.
What type of reaction occurs when atoms combine to form molecules or when molecules break down into?
These are two forms of a chemical reaction. The first type is called synthesis and the other decomposition.
Who was the first person to describe a chemical reaction as the recombination of atoms?
neils bohr
Results for Calculate The Amount In Moles Of Molecules For Each Substance. A) A Sample Of Ammonia NH3(g) Containing 8.1x1020 Atoms Of Hydrogen?
NH3 Molecules = ( 8.1 x 10^20 H atoms ) ( 1 NH3 molecule / 3 H atoms ) NH3 Molecules = 2.7 x 10^20 NH3 molecules NH3 moles = ( NH3 molecules ) / ( N Avogadro ) NH3 moles = ( 2.7 x 10^20 NH3 molecules ) / ( 6.022 x 10^23 molecules / mole ) NH3 moles = 4.48 x 10^-4 NH3 moles <--------------
