A combustion reaction involves an organic compound reacted with oxygen. The general chemical equation is as follows:
<span>
Organic Compound + Oxygen = CO2 + H2O
</span><span>To calculate the amount of C present in the original sample, we use the values given and assume that there is complete combustion that is happening.
</span><span>
7.33 g CO2 ( 1 mol CO2 / 44.01 g CO2)(1 mol C / 1 mol CO2) = 0.167 mol C
Therefore, 0.167 mol of C was originally in the sample.</span>
Answer:
group 1 - cations charge +1
group 7 - anions charge -1
Explanation:
Group 1 has one valence electron and will lose one electron to complete the octet.
Group 7 has 7 valence electrons and will accept an electron to complete the octet.
A.
When you cut your skin the cells at the edge of the injury are stimulated to divide rapidly.

According to Bohr, the electrons in an atom were only allowed to exist at certain energy levels. ... Just as children cannot hover between two steps on a staircase, Bohr suggested that electrons cannot hover between two energy levels in the atom. Bohr developed his energy level model further using principles from physic
Answer:
soluble because all compounds containing K are soluble
Explanation:
Most metal hydroxides are insoluble. However, alkali metal hydroxides (such as KOH and NaOH) are very soluble.
In the case of KOH, the K cation is attracted to the electronegative oxygen on water. The OH anion is capable of hydrogen bonding to the water. (Notice how OH⁻ is simply the deprotonated form of water.)
