Hey there!

Mass = 10 g

Density = 0.7 g/mL

Volume = ?

Therefore:

D = m/ V

0.7 = 10 / V

V = 10 / 0.7

V = 14.28 mL

Hope that helps!

In a particular enzyme, an alanine residue is located in a cleft where the substrate binds. A mutation that changes this residue
TiliK225 [7]

Explanation:

There are non-polar side chains also present in alanine. And, these non-polar side chains are involved in some hydrophobic interactions in active sideand then it changes into polar amino acid glutamate that will destroy the hydrophobic interaction.

Whereas in glycine there is only hydrogen present in the side chain therefore, it will not affect much.

Scoring Scheme: 3-3-2-1 Part II. You considered the properties of two acid-base indicators, phenolphthalein and methyl orange. M
kotykmax [81]

Answer:

Explanation:

Phenolphthalein is a protonated indicator and methyl orange is a basic indicator having hydroxyl ionisable part .

Phenolphthalein can be represented by the following formula

HPh  which ionizes in water as follows

       HPh        + H₂O      ⇄    H₃O⁺      +        Ph⁻

( colourless  )                    ( pink  )

In acidic solution it is in the form of protonated Hph form which is colourless

In basic medium , it ionises to give H₃O⁺ and unprotonated  Ph⁻ whose colour is pink .

When a hydrogen atom covalently bonds to another atom, how many electrons associated with this hydrogen atom become involved in
STatiana [176]

Explanation:

A covalent bond is defined as the occurrence of a bond due to the sharing of electrons between the combining atoms.

Atomic number of hydrogen atom is 1 and its electronic configuration is 1s^{2}. So, in order to complete its octet it needs to gain or mutually shares one electron.

A covalent bond is generally formed between non-metal atoms.

Thus, we can conclude that hydrogen has only one electron that will be involved in the formation of a covalent bond.
