Convert 25 gram of carbon dioxide to mold
Rus_ich [418]

The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.

44.009 grams of CO2 = 1 mole of CO2             CO2 = Carbon dioxide

25 ÷ 44.009 ≈ 0.568

About 0.568 moles of CO2

Name the element described in each of the following:
musickatia [10]

Period  4  transition  element  that  forms  2+  ion  with  a  half‐filled  d  sub level  is
Manganese  (Mn)

What is the half-filled d sub-level?

Transition metals are an interesting and challenging group of elements.  They have perplexing patterns of electron distribution that don’t always follow the electron-filling rules.  Predicting how they will form ions is also not always obvious.

Transition metals belong to the d block, meaning that the d sublevel of electrons is in the process of being filled with up to ten electrons.  Many transition metals cannot lose enough electrons to attain a noble-gas electron configuration.  In addition,  the majority of transition metals are capable of adopting ions with different charges.  Iron, which forms either the Fe2+ or Fe3+ ions, loses electrons as shown below.

Some transition metals that have relatively few d electrons may attain a noble-gas electron configuration.  Scandium is an example. Others may attain configurations with a full d sublevel, such as zinc and copper.

Describe the steps used to create Lewis dot structures to represent covalent bonds.
antiseptic1488 [7]
1)Identify the atoms that are participating in a covalent bond.
2)Draw each atom by using its element symbol. The number of valence electrons is shown by placing up to two dots on each side of the element symbol, with each dot representing a single valence electron.
3)Predict the number of covalent bonds each atom will make using the octet rule.
4)Draw the bonding atoms next to each other, showing a single covalent bond as either a pair of dots or a line representing a shared valence electron pair. If the molecule forms a double or triple bond, use two or three lines to represent the shared electron pairs, respectively.
