HCCH? That would be drawn like shown below. It doesn't look the greatest, sorry about that.
Answer: 0.910 moles NA+
Definition: of Like Decimal: Two or more decimal fractions are called like ... 0.910; 10.819; 89.637; 142.800 (b) 12.01; 180.3; 1446.105; 180.19
Answer:
189.6 mL
Explanation:
As per Boyles law when a gas is kept at a constant temperature and mass in a closed container, the volume and pressure vary inversely.
P1V1= P2V2
Here, P1 = 0.79 atm, V1 = 240 ml, P2= 1 atm
therefore, substituting values in above equation we get
0.79×240 = 1×V2
⇒V2 = 189.6 ml
therefore, its volume at STP (1 atm and 0 oC) = 189.6 ml

Answer:
A. Ionic—Magnesium will give 2 electrons to oxygen, and both will become ions.
Explanation:
An ionic bond will form between the ions of both atoms. Ionic bonds forms when there is transfer of electrons between two atoms so as to achieve a noble configuration.
In the given problem, magnesium is a metal and highly electropositive. This implies that it will readily donate its valence electrons. Oxygen on the other hand is highly electronegative, to complete its outer shell configuration, it requires just two more electrons.
The transfer of the two electrons to the oxygen atom sets up an electrostatic force of attraction between the two ions and an ionic bond results.
