Tantalum is an element with an atomic number of 63 and its electronic configuration is:
[Xe] 4f¹⁴ 5d³ 6s²
Answer: Graphite is nonpolar carbon which associates with the nonpolar hexanes. The cellulose in the exposed paper contains polar regions that are attracted to the polar water.
Explanation:
The question is incomplete, complete question is:
A fluid occupying
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V = 
Density of the fluid = D

Specific volume is the reciprocal of the density :

Specific volume of the fluid = 

2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft

Specific volume of the fluid :

3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft

Specific volume of the fluid :

Answer:
Thermohaline Circulation
Explanation:
The process is known as “Thermohaline Circulation”. In the Earth’s polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
Answer:
D) 152 g
Explanation:
a mass of 1 mol Cr2O3 = 2 × 52 + 3 × 16 = 152 g number of moles of Cr2O3.
