How are ions different from an electrically neutral atom

The charge from a proton or electron are of equal strength, therefore if an atom has an equal number of protons and electrons, it will be electrically neutral. However, atoms are not always electrically neutral, in which case they are called ions. (scienceline.ucsb.edu/getkey.php?key=4554)

Which of the following is a molecular formula for a compound with an empirical formula of CH2O and a molar mass of 150. g/mol.

trapecia [35]

Answer:

C₅H₁₀O₅

Explanation:

Let's consider a compound with the empirical formula CH₂O. In order to determine the molecular formula, we have to calculate "n", so that

n = molar mass of the molecular formula / molar mass of the empirical formula

The molar mass of the molecular formula is 150 g/mol.

The molar mass of the empirical formula is 12 + 2 × 1 + 16 = 30 g/mol

n = (150 g/mol) / (30 g/mol) = 5

Then, we multiply the empirical formula by 5.

CH₂O × 5 = C₅H₁₀O₅

What is the pOH of a 1 x 10^-8 M solution of HNO3?

Sedaia [141]

Explanation:

to find POH u need PH first

so ph=-log(h3o)

$ph = - log(1 \times {10}^{ - 8} ) \\ \\ ph = 8 \\ ph + poh =14 \\ poh = 14 - 8 \\ poh = 6$
