What is the tendency of water molecules to stick to molecules of another substance?
The tendency of water molecules to stick to molecules of another substance is known as adhesion. Water molecules have a strong attraction to other molecules due to their polarity, forming hydrogen bonds with the molecules of a different substance. This adhesion property of water allows it to interact with and dissolve a wide variety of substances.
What does 6h2o stand for?
6H2O represents 6 molecules of water. The "6" indicates the number of water molecules present.
How many kj of energy will be released when the bonds in the two moles of water molecules are formed?
The energy released when the bonds of two moles of water molecules are formed is approximately 94 kJ. This energy is released because the bonds formed in water are stronger than the bonds broken in its constituent elements, hydrogen and oxygen.
What is the figure that gives the number of identical molecules in a formula?
The subscript in a chemical formula indicates the number of identical molecules present. For example, H2O indicates two molecules of water present.
When salt is dissolved in water what is formed?
Salt water. When the salt dissolves, it is not a chemical reaction, so no new substance is created. The water molecules surrounded each ion in the solid NaCl separating the Na+ ions from the Cl- ions.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
Each water molecule contains two hydrogen atoms. Therefore, the number of water molecules present in the sample can be calculated by dividing the number of hydrogen atoms by 2. In this case, 3.6 moles of hydrogen atoms corresponds to 1.8 moles of water molecules. This is equal to approximately 1.08 x 10^24 water molecules.
How many molecules are there in 31.8 moles of water?
A number of atoms/molecules in a given number of moles is regardless of the substance unless it deals with stoicheometry. One mole represents a number of Avogadro's constant, approximately 6.022 x 10^23. Therefore there are 1.91 x 10^25 molecules of water in 31.8 moles.
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
How many molecules are there in 2 moles of water?
There are approximately 1.204 x 10^24 molecules in 2 moles of water. This is because 1 mole of a substance contains 6.022 x 10^23 molecules. Therefore, 2 moles would contain twice that number.
How many moles of water molecules H2O are present in a 27 gram sample of water?
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
How many molecules of water does a 50g sample of H2O have?
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
How many molecules of water are produced if 2.0g of sodium sulfate are produced in the above reactionH2SO4+2NaOH=H2O+Na2SO4?
The reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.
How many moles are in 3.612 X 1024 molecules of H2O?
To find the number of moles in 3.612 × 10^24 molecules of H2O, divide the number of molecules by Avogadro's number, which is approximately 6.022 × 10^23 molecules/mol. 3.612 × 10^24 molecules / 6.022 × 10^23 molecules/mol ≈ 6 moles of H2O.
How many molecules of water are in 5.65 moles of water?
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
How many moles of water H2O contain 2.0X1022 molecules of water?

Which one has more molecules 9 g of water or 9 g of suger (C12 H22 O11)?
To determine which substance has more molecules, we need to calculate the number of moles for each substance using their respective molar masses. The molar mass of water (H2O) is approximately 18 g/mol, while the molar mass of sugar (C12H22O11) is about 342 g/mol. For 9 g of water, the number of moles is 9 g / 18 g/mol = 0.5 moles. For 9 g of sugar, the number of moles is 9 g / 342 g/mol ≈ 0.026 moles. Therefore, 9 g of water has more molecules because it contains 0.5 moles, which is significantly higher than the 0.026 moles in 9 g of sugar.
How many moles of water molecules h2o are present in a 27 rams sample of water?
To find the number of moles of water molecules in a 27 gram sample, you need to divide the mass by the molar mass of water (18.015 g/mol). 27 g / 18.015 g/mol = approximately 1.5 moles of water molecules.
