you have an object with mass of 86 g and volume of 10 cm^3 (cubed). calculate density, show your work, and identify which materi

sleet_krkn [62]

Answer:

8.6g/cm³ (BRASS)

Explanation:

Given the following :

Mass of object = 86g

Volume of object = 10cm³

The density of an object is calculated using the formula :

Density(g/cm³) = mass(g) / volume(cm³)

Inputting our values :

Density = 86g / 10cm³

Density = 8.6g/cm³

According to the table provided, the object which corresponds to having a density of 8.6g/cm³ is BRASS

Which of the following is necessarily characterized by a covalent linkage?a. Base-pairing interactionb. Disulfide bondc. Hydroge

mr_godi [17]

Answer:

b. Disulfide bond

Explanation:

Covalent linkage or bonding is a type of bond in which electrons are shared between atoms in a compound or molecule. Each atom contributes to the shared electron.

This is the case of disulfide bonding i.e. S-S, in which two thiol groups (-SH) share electrons with one another. The process of oxidation between two cysteine (amino acid) molecules forms this bond. Hence, Disulfide bond is characterized by a covalent linkage.
