Given the equation: Ca(CO3) + 2NaOH > Ca(OH)2 + Na2(CO3) How much Ca(CO3) is needed to produce 2.3 moles of Na2(CO3)?
Show all your work please, and thank you!

2+2 is 4-1 that’s three quick maths every day man’s on the block smoke trees see that girl in the park that girl is Ockers

there needs to be 4 Ca(CO3)

Explanation:

b i think it’s a water wheel turning in a stream

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
