Answer:

A better term than

covalency

might be

molecularity

. Molecular species TEND to have reduced melting points and boiling points with respect to non-molecular species. Non molecular species, which include sodium chloride, and graphite, and diamond, thus have much HIGHER melting points than methane or ethane, or water, which are composed of discrete molecules.

B. Why is this number called a "mass” number?

deff fn [24]

Answer:

The mass of the atom depends on the sub atomic particles present in the nucleus of an atom.

That is, the protons and the neutrons.

Electrons are present around the nucleus and the mass is negligible since its mass is very very less.

mass of a proton = $1.673\times10^{-27} kg$

mass of a neutron = $1.675 \times 10^{-27} kg$

mass of an electron = $9.109 \times 10^{-31} kg$

Mass number represents the mass of one particular isotope and it is a whole number for example, $_6 C^{13}$

Mass number is 13 and atomic number is 6 for the carbon isotope C-13.

Atomic mass is different from mass number and it is a fraction since it is the average atomic mass of all the isotopes of an atom.

Atomic mass of C is 12.011 amu which we see in the periodic table is the average atomic mass of isotopes C-12, C-13 and C-14.

Problem page a virus has a mass of ×9.010−12mg and an oil tanker has a mass of ×3.0107kg . use this information to answer the qu

faltersainse [42]

A. The mass of one mole of the virus is calculated by multiplying the mass of a single virus by the Avogadro's number which is equal to 6.022 x 10^23. Performing this operation,

mass = (9.0 x 10^-12 mg)(6.022 x 10^23) = 5.42 x 10^12 mg

In correct number of significant figures, the answer would only have to be 5.4 x 10^12 mg.

b. The number of moles of the virus that will have the same mass as the oil tanker is calculated by dividing the mass of the oil tanker by the mass of one mole of the virus. Note that doing division, both would have to have the same units.

n = (3.0 x 10^7 kg) / (5.4 x 10^12 mg)(1 g/1000 mg)(1 kg/1000 g)

Simplifying,
n = 6

In correct number of significant figures, the answer is 6.0.

using the soubility curve what is the solubilityof nh4cl in 10 mL of water at a temperature of 60 degrees Celsius

lukranit [14]

Answer:

Please, see attached two figures:

The first figure shows the solutility curves for several soluts in water, which is needed to answer the question.

The second figure shows the reading of the solutiblity of NH₄Cl at a temperature of 60°C.

Answer: 5.5g

Explanation:

The red arrow on the second attachement shows how you must go vertically from the temperature of 60ºC on the horizontal axis, up to intersecting curve for the solubility of NH₄Cl.

From there, you must move horizontally to the left (green arrow) to reach the vertical axis and read the solubility: the reading is about in the middle of the marks for 50 and 60 grams of solute per 100 grams of water: that is 55 grams of grams of solute per 100 grams of water.

Assuming density 1.0 g/mol for water, 10 mL of water is:

$10mL\times 1.0g/mL=10g$

Thus, the solutibily is:

$10gWater\times 55gNH_4Cl/100gWater=5.5gNH_4Cl$
