Answer:

When atoms from Column I (Group 1) combine with atoms from Column VII (Group 17) <u><em>the bond will be ionic.</em></u>

Explanation:

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

In other words, by forming ionic compounds, the elements to the left of the periodic table usually lose electrons, and form a cation that has the same electronic configuration as the nearest noble gas. The elements to the right of the periodic table tend to gain electrons to reach the electronic configuration of the next noble gas .

This type of bond is produced by the attraction of ions with opposite charges. By assigning or accepting the valence electrons, the ions comply with the octet rule and are more stable. Remember that valence electrons are the electrons of the outermost layer of the atom, which can participate in chemical bonds.

It is also possible to think that an ionic bond is formed when two atoms have a very large electronegativity difference, remembering that electronegativity is the property of an atom to attract an electron.  And this large difference in electronegativity usually occurs between the atoms of Column I (Group 1) combined with atoms of Column VII (Group 17).

Then it is finally possible to say that <u><em>"When atoms from Column I (Group 1) combine with atoms from Column VII (Group 17) the bond will be ionic."</em></u>

A 4.7-L sealed bottle containing 0.33 g of liquid ethanol,C₂H₆O, is placed in a refrigerator and reaches equilibrium with its va
Mama L [17]

The mass of ethanol present in the vapor is 8.8×10⁻²g. when liquid and vapor ethanol at equilibrium.

The volume of the bottle = 4.7 L

Mass of ethanol = 0.33 g

Temperature (T1) = -11 oC = 273-11 = 262 K

P1 = 6.65 torr

Now we will calculate the mole by applying the ideal gas equation:-

PV = nRT

Or, n = PV/RT

Where P is the pressure

 T is the temperature

 R is the gas constant = 0.0821 L atm mol-1K-1

 V is the volume

Substituting the values of P, V, T, and R the mole of ethanol is calculated as:-

  = 0.001913 mol C2H6

Conversion of the mole to gm

Molar mass of ethanol (M) = 46.07 g/mol

Mass of C2H6O =0.001913 mol C2H6O 46.07 g/mol = 0.088 =  8.8×10⁻²g.

Hence, the mass of ethanol present in the vapor is found to be  8.8×10⁻²g.

Cobalt III hydroxide and nitric acid react according to the following balanced equation:
kati45 [8]
The mass of cobalt (III) needed is
m = 5.2 L (0.42 mol/L) ( 93 g/mol)
m = 97.65 g

The volume of nitric acid needed is
V = 5.2 L (0.42 mol/L) (3 mol / 1 mol) (1000 mL/1.6 mol)
V = 1968.75 mL

The moles of water produced is
n = 5.2 L (0.42 mol/L) (3 mol / 1 mol)
n = 3.15 moles

Sam believes the rock is more denser than the pencil. He measured the mass of the rock to be 8.5 grams and volume to be 4.5mL. H
mezya [45]

Answer:

Rock

Explanation:

Let's calculate the density of each object:

Rock:

Density = \frac{mass}{volume}=\frac{8.5\ g}{4.5\ mL}=1.9\ g/mL

Pencil:

Density = \frac{mass}{volume}=\frac{2.4\ g}{4.5\ mL}=0.53\ g/mL

Therefore the rock is denser.
