Law Incorporation [45]

Answer:

Using solar energy, hydroelectric energy and wind are major ways of conserving natural resources. Trees and other organic energy sources are traditional sources of renewable energy. Forests can be replanted and hemp and other organic materials such as ethanol can be used to preserve natural resources.

A 250 mL Erlenmeyer flask has a measured volume of 287mL. The experiment is performed with a this flask but the volume of 250 mL
mart [117]

Answer:

There will be a high effect on the calculation because a lower molar mass will be reported.

Explanation:

Hello,

In this case, since a higher volume is used, a higher value is taken into account when dividing to get the molecular mass. In such a way, the calculated molecular mass will be surely lower than the real molecular mass implying that there will be a high effect on the required calculation, nevertheless, as 37mL is a considerable mistake, the effect won't be too high.

Best regards.

Explain why hcl has a smaller dipole moment than hf, even though the h−cl bond is longer than the h−f bond.
ryzh [129]

Dipole moment measures the polarity of the molecule that is measure of the separation of two opposite charges. Electronegativity difference between the atoms results dipole moment.

Dipole moment of bond is equal to the product of the magnitude of charge and distance between them (charges).

It is given by:

\mu = e\times d

where,

\mu = dipole moment

e = magnitude of charge whether partially positive or negative charge.

d = distance between charges.

Since, H-Cl bond distance is larger than theH-F bond distance, because of large partial charge on the atoms of H-F; from the definition of dipole moment H-Cl (1.08) has smaller dipole moment than H-F (1.82).
