Scientists believe that interactions between atoms depend mostly on the arrangement of the outermost electrons in each atom. Thi

s theory is MOST supported by the observation of similar reactions among elements —
with a similar atomic mass
with a similar atomic number
in a group (column) of the periodic table
in a period (row) of the periodic table

I’m pretty sure it’s in a group (column) of the period table. Hope this helps :)))

A similarity between the forces involved in both ionic and covalent bondingis that bothO A) involve the sharing of electrons.O B
almond37 [142]
Stating the difference between covalent and ionic bonding....

ionic bonds consist of the transfer of electrons, and covalent consists of the sharing of electrons.

This being said..answer choices A and B are out of the picture.

Thus, answer choice C is your answer.

Involve the attraction of opposite charges;require same amount of energy to break their bonds.

An energy bill indicates that the customer used 1024 kWh in July. How many joules did the customer use?
Triss [41]

Answer:

3,686,400,000 Joules

Explanation:

Energy = 1024 kWh

To be converted to Joules.

The relationship between kwh and joules is;

1 kilowatt-hour = 3600000 J

So we have;

1 = 3600000

1024 = x

x = 1024 * 3600000

x = 3,686,400,000 Joules

for the following reaction how many grams of h20 will be produced if you react 3.7 grams of B2H6? B2h6 +3O2-2hbo2+ 2 H20
Nana76 [90]

Answer:

4.8 g H₂O

Explanation:

To find the mass of water, you need to (1) convert grams B₂H₆ to moles B₂H₆ (via molar mass from periodic table), then (2) convert moles B₂H₆ to moles H₂O (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles H₂O to grams H₂O (via molar mass from periodic table).

It is important to arrange the ratios/conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 2 sig figs because the given value (3.7 grams) has 2 sig figs.

Molar Mass (B₂H₆): 2(10.811 g/mol) + 6(1.008 g/mol)

Molar Mass (B₂H₆): 27.67 g/mol

1 B₂H₆ + 3 O₂ ---> 2 HBO₂ + 2 H₂O
^                                             ^

Molar Mass (H₂O): 15.998 g/mol + 2(1.008 g/mol)

Molar Mass (H₂O): 18.014 g/mol

3.7 g B₂H₆          1 mole            2 moles H₂O           18.014 g
----------------  x  ---------------  x  -----------------------  x  -----------------  =  4.8 g H₂O
                          27.67 g           1 mole B₂H₆              1 mole

What are valence electrons of an atom used for?
Murrr4er [49]

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
