PV = nRT
⇒P1/T1 = P2/T2
⇒500/300 = 100/T2
⇒ T2 = 100×300/500 = 60K
Answer is D
Answer:
b. The nitrogen atom shares one valence electron with each iodine atom, which also shares one valence electron each with the nitrogen atom.
Explanation:
The formula of nitrogen triiodide is NI3. In this compound, the nitrogen atom shares one valence electron with each chlorine atom which in turn also shares a valence electron with nitrogen.
Recall that covalent bonding involves a sharing of <u>valence </u> electrons. Transfer of electrons is typical of ionic bonds between a metal and a nonmetal. nitrogen and iodine are nonmetals hence they bond covalently.
Hence, the formation of NI3 leaves three lone pairs on each chlorine atom and one lone pair on the nitrogen atom.
Answer:
The correct answer is:
2.6 m3 (B)
Explanation:
SF unit stands for Stowage factor unit. Stowage factor is the volume occupied by one unit of mass (weight) when stowed in cargo space. SF expresses the unit in cubic meters (m³) or cubic feet. SF is a unit of measurement that indicates how much space (volume) a particular unit of cargo occupies in a ship's cargo compartment
Answer:
7g/cm³
Explanation:
Given parameters:
Mass of the mineral = 21g
Volume = 3cm³
Unknown:
Density of the mineral = ?
Solution:
Density of a substance is the mass per unit volume of the substance.
Density =
Now insert the given parameters and solve;
Density = = 7g/cm³
The mineral with a density of 7g/cm³ is Galena, an ore of lead.
Im dying at the fact that you put in under ‘Chemistry’, good luck though.
