Hope it helps! Brainliest answer, PLZ? :)
It has more electrons, meaning more orbitals, pls give brainliest.
The correct answer to the question that is being presented above would be 'one (1) grain'. The The <em>grain</em> often poses a conversion problem for pharmacy personnel, as most pharmacists consider it to be equal to 65 mg, but manufacturers consider it <span>equal to 60 mg.</span>
Water is deemed as a polar molecule because of the electrostatic attraction occurring between molecules. One major key characteristic of knowing polar molecules is knowing their atomic geometry. Now, we know that water has two hydrogens and one oxygen atom covalently bonded to each other. This means that they share electrons. However, this sharing is unequal because oxygen is more electronegative compared to hydrogen. So, the electrons tend to be nearer to the oxygen atom making it partially negative. On the other hand, the hydrogen would be partially positive. Polarity arises when there is an imbalance in the pull of electrostatic forces between individual atoms. If you look at the molecular geometry of water, its shape is bent. As a result, it creates a dipole moment which attracts solute to bond with water. In chemistry, the primary rule of solubility is that 'like dissolves like'. This means that polar solutes will dissolve in polar solvents. Similarly, nonpolar solutes will dissolve in nonpolar solvents.
Combustion of hexane can be illustrated by the following reaction:
2C6H14 + 19O2 ...........> 12CO2 + 14H2O
From the periodic table:
mass of hydrogen = 1 gram
mass of oxygen = 16 grams
mass of carbon = 12 grams
Therefore:
molar mass of hexane = 6(12)+14(1) = 86 grams
mass of water = 2(1)+16 = 18 grams
From the balanced equation above:
2(86) = 172 grams of hexane produce 252 grams of water. To know the amount of water produced from 1.33 grams of hexane, all you have to do is cross multiplication as follows:
amount of water = (1.33x252) / 172 = 1.9486 grams
