which of these elements has the greatest attraction for electrons in a covalent bond?

A. Se
B. As
C. Br
D. Kr
​

Answer:

sugar

Explanation:

sand will not dissolve in water because the bond in water isn't strong enough to dissolve it.

so sand is a big no.

so the answer is the other option: which is sugar.

Answer:

Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).

Answer:

A dry gas, that is a natural gas, is the form in which gas can be measured.

And gas is measured in cubic meter, that is, it's volume is measured and the size of gas can be determined.

All the best!

Answer:

The full electron configuration for an N2− ion is 1s^2 2s^2 2p^5

The electronic configuration of the N²⁻ ion is 1s²2s²2p⁵.

The electron configuration can be described as how electrons are distributed in different energy levels or electron shells of an atom of an element. In the electron configuration of an atom, the number of electrons can be written as a superscript of electron atomic subshells. For example, the electron configuration of magnesium can be written as 1s²2s²2p⁶3s².

The principal quantum number (n) can be defined as the maximum number of electrons that can be filled in an electron shell of an atom. The formula used to determine is 2n², where ‘n’ is the principal quantum number.

The atomic number of the nitrogen atom is 7 and the electronic configuration is 1s²2s²2p³. When it gains two electrons then it has 9 electrons in total. The nine electrons can be filled as  1s²2s²2p⁵.

Therefore, the electronic configuration of the N²⁻ ion is 1s²2s²2p⁵.

Answer:

The controlled variable of an experiment is the one thing that stays the same in an experiment.

Explanation:

An example would be : if I have two pennies, both dunked in water, but than I change one to be dunked in vinegar, the one dunked in water still is the constant or the controlled variable.

Answer:

The overall chemical reaction between baking soda (sodium bicarbonate) and vinegar (weak acetic acid) is one mole of solid sodium bicarbonate reacts with one mole of liquid acetic acid to produce one mole each of carbon dioxide gas, liquid water, sodium ions, and acetate ions. The reaction proceeds in two steps

Explanation:

Molar mass of Lithium is 6.9410 g/mol.

This means 1 mol of Li atoms weigh 6.9410 g

In 1 mol 6.022 x 10 ^ 23 atoms should be present

So, in 6.9410g , there should be 6.022 x 10 ^ 23 atoms.

So weight of 1 atom = a =  6.9410  g / (6.022 x 10^ 23)

To find weight of 3.25 x 10 ^ 24 atoms we have to multiply a by 3.25 x 10^ 24

So you will get the answer as

[6.9410  g / (6.022 x 10^ 23)]   x 3.25 x 10^ 24

= 37.46 g

Answer:

Explanation:

Answer:

magnesium chlorides are solids with high melting and boiling points because of the large amount of heat which is needed to break the strong ionic attractions.

Explanation:

These magnesium ions have more than one charge (2+). These highly charged ions will attract other ions more strongly than ions with one charge, therefore more energy will be needed to overcome the electrostatic forces of attraction and so the melting points will be higher.
