The ratio of the moisture content in the air compared to the maximum amount of moisture that the air can hold at its current tem
PSYCHO15rus [73]
<h2>Relative Humidity</h2>

Explanation:

  • Humidity is the amount of moisture content present in the atmosphere.

    Humidity is of two types:

  1. Absolute humidity.
  2. Relative humidity.
  • Absolute humidity is the ratio of  the amount of moisture content in the air to the unit volume of the air.
  • Relative humidity can be derived as the ratio of moisture content in the air to the maximum amount of moisture that the air constitutes.
  • Hence, the required answer is Relative humidity.

Draw an example each of a hydrogen atom that can and can’t participate in hydrogen bonding.
frutty [35]

Answer:

A hydrogen bonding is a bond class that is produced from the attraction existing in a hydrogen atom and an oxygen, fluorine or nitrogen atom with a negative charge. This attraction, meanwhile, is known as dipole-dipole interaction and links the positive pole of one molecule with the negative pole of another.

Explanation:

The hydrogen atom, which has a positive charge, is known as the donor atom, while the oxygen, fluorine,  chlorine or nitrogen atom is the bond acceptor atom. In the substance in which they are most effective is in the water.

Hydrogen bonds have only one third of the strength of covalent bonds, but they have important effects on the properties of the substances in which they occur, especially in terms of melting and boiling points in crystal structures.

What is back titration?​
Yakvenalex [24]

Answer:

Back titration is a titration done in reverse; instead of titrating the original sample, a known excess of standard reagent is added to the solution, and the excess is titrated.

Is CaC1 a ionic , Polar covalant or non polar covalent ?
patriot [66]

Polar Covalent.

This is because both Calcium (Ca) and Carbon (C) are non metals, thus eliminating the ionic option.

It is polar covalent rather than nonpolar covalent due to the fact that the electrons in a polar covalent bond are shared unequally while those in a nonpolar bond are shared equally.

This can be determined by looking at the amount of valence electrons; if the electrons cancel each other out, it is shared equally. If not, it is shared unequally.

Hope this helps!

Sandy water is a heterogeneous mixture. ...

A pepperoni pizza is a heterogeneous mixture.

Explanation: A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. ... A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase.
