How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many molecules are in 6.9 g H2O?
To determine the number of molecules in 6.9 g of water (H2O), you first need to convert grams to moles. The molar mass of water is approximately 18 g/mol. Therefore, 6.9 g is equal to 6.9/18 = 0.383 moles of water. Next, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in 0.383 moles of water, which is approximately 2.3 x 10^23 molecules.
What is the chemical symbol for ice?
The chemical symbol for ice is H2O, which represents the water molecule. Ice is the solid phase of water, where water molecules are arranged in a crystalline structure.
Water molecules are a reactant for?
Water molecules are a reactant for many biochemical reactions in living organisms, including photosynthesis and cellular respiration. Additionally, water can also be a reactant in chemical reactions to produce acids or bases.
How many series are their out of the DVD ' h20 just add water'?
There is only three seasons on the H20 Just Add Water DVDs because there isn't a fourth season.
Are h20 and ozone both molecules?
Yes, H2O and Ozone both are molecules. H20 is water.
How many molecules are in 4.21 grams of water?
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
How many H20 molecules are present in 2 kg of water?
it would be 2 L not 2 Kg
What is of h20?
h20 is Water! Water H and 2 stand for 2 hydrogen molecules, while O means one oxygen molecule.
What is the code for h20?
H20 is a formula for water. The substance has 2 hydrogen molecules to every 1 oxygen molecule.
How many oxygen atoms are in 6h20?
Two. The equation means two water molecules, H20. Thus you have 4 hydrogens and 2 oxygens.
Why is water evaporation a physical change and not a chemical change?
Nothing is chemically changed when water goes from liquid-->gas. All that's happening is the molecules moving faster. H20(l)-->H20(g)
What are the final waste product of cellular respiration?
Water and carbon dioxide (H20) (CO2)
Is 2 H20 a chemical reaction?
2 H2O is the chemical formula of two molecules of water, not a reaction.
What allows liquid water to exist?
Liquid water exists based on the molecular structure of the water, and the temperature of those molecules. Liquid water is water, H2O within a temperature range of 0-100 degrees celsius. The H20 compounds cling to other H20 compounds due to gravity, and a large amount of H2O compound form molecules of water.
How does salt increase water denisity?
Consider the body you are talking about. Imagine a 1by1by1 foot cube of water. Water is H20. now imagine pouring salt into the cube. It would mix in and disolve, but some water would be pushed out, because the salt must displace some of the water. Since salt molecules (Sodium Chloride) are denser molecules than H20 molecules, the same volume of solution would be denser.
Which molecule is split apart during the light ractions in photosynthesis?
Water or h20
