The <span>simple machine found on the head of the  ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used to split wood, the ax handle exerts a force on the blade of the axe, which is the wedge. That force pushes the wedge down into the wood. The wedge in turn exerts an output force splitting the wood in two.

Assume after recording the mass of KHP on the weigh paper it was not completely transferred into the Flask. Your following titra
maxonik [38]

Answer:

unchanged

Explanation:

KHP is potassium hydrogen phthalate. It is a weak acid. It forms a colourless ionic weakly acidic solution which can be titrated against NaOH to determine the concentration of a sodium hydroxide solution. KHP is used as a primary standard. Its concentration depends on the mass of solid added and the volume of solution.

If all the KHP was not transferred into the flask, the experimental value of the concentration of NaOH remains unchanged as long as the titration was carried out correctly and following normal procedure. Only the concentration of the KHP will be affected by this error during calculation.

What intermolecular force(s) is/are present in solid SO3?
guapka [62]

Answer:

1. London dispersion

Explanation:

Sulphur trioxide ( SO₃ ) -

The chemical compound SO₃ is planar in structure , the only intermolecular forces shown by SO₃ is the London forces .

dipole - dipole is not observed in this compound , as it is not possible to generate poles between the sulfur and oxygen atom due to very less difference in the electronegativity .

Hydrogen bonding is also not observed , because there is not hydrogen atom .

Hence , only London forces are observed in SO₃ .
