Very simply, you get twice as much Hydrogen as Oxygen, because the chemical formula is H2O, meaning two hydrogen atoms bonded to one oxygen atom.
<h3><u>Answer;</u></h3>
- Molecules along the surface of a liquid behave differently than those in the bulk liquid.
- Cohesive forces attract the molecules of the liquid to one another.
- Surface tension increases as the temperature of the liquid rises
<h3><u>Explanation;</u></h3>
- Surface tension is measured as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules.
- A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions, while a molecule at the surface of a liquid experiences only net inward cohesive forces.
- Surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity.
Answer:0.0054314469917931 mole using the molecular weight calculator and the molar mass of MgBr2.
Explanation:
——>Ba+AlCl2
—->3Ba+2AlCl3 to balance the equation
speed and direction in which an object is moving. both speed and direction of motion. is a vector. two or more velocities add by velocity addition.
