Answer the following question given this paragraph: The formula unit of sodium chloride dissociates into one sodium ion and one chloride ion. The calcium nitrate formula unit dissociates into one calcium ion and two nitrate ions. This is because of the 2+ charge of the calcium ion. Two nitrate ions, each with a 1 charge are required to make the equation balance electrically. The ammonium phosphate formula unit dissociates into three ammonium ions and one phosphate ion. Note that the polyatomic ions themselves do not dissociate further, but remain intact. Q: The formula unit of sodium chloride dissociates into one sodium ion and one? Choices: - oxygen ion - magnesium ion - electron - chloride ion A:
chloride ion

(Q).
Answer the following question given this paragraph: The landscape of the Moon - its surface features - is very different from Earth. The lunar landscape is covered by craters caused by asteroid impacts ( Figure below ). The craters are bowl-shaped basins on the Moon's surface. Because the Moon has no water, wind, or weather, the craters remain unchanged. Q: The lunar landscape is covered by craters caused by what? Choices: - earth impacts - volcanoes - water - asteroid impacts A:
(A).
asteroid impacts
Ques:Answer the following question given this paragraph: The general trend in electronegativity is that the value increases from left to right across a row in the periodic table and decreases down a column. The most electronegative element is fluorine, which has a value of 4.0. As discussed in the lesson "Trends in the Periodic Table," electronegativity increases across a row as the number of protons in the nucleus increases and therefore has a stronger pull. Electronegativity decreases down a column due to an increased effect of electron shielding in larger atoms. Q: Generally speaking, electronegativity values ______ from left to right across a row in the periodic table and _______ down a column. Choices: - reverse, descend - move, fall - decrease, increase - increase, decrease A:

Ans:increase, decrease
