Answer:
it's because they have one electron in there valence shells.
I hope this helps
Answer:
110.7 kpa or 1.097 atm your choice of pressure units
Explanation:
We can assume the Volume is constant since we are not told other wise and it is indeed a car. We can Use P1/T1= P2/T2
So (T2xP1 )/ T1 = P2
(318Kx101.3kpa)/291k = 110.7 kpa or 1.097 atm your choice of pressure units
if your wondering why i used Kelvin gas laws are always in units of Kelvin
A molecule consists of group of atoms that are bonded together by chemical bond. It is the smallest particle of an element or a compound that has the properties of the element or the compound embedded in it. The atoms present in one element easily forms a bonding with the atoms of another element to form molecules. The size and complex nature of molecules varies hugely. Some molecules can have a single atom as is the case with helium, while in several other elements the number of atoms in the molecule can be more than one.
Answer:
d. magnesium sulfide, mgs
Explanation:
Ionic bonds or also called eletrovalent bond is one of the chemical bonds that forms between the atoms of molecules or compounds. It is the kind of bond that forms between a positively charged atom and a negatively charged atom. The positive atom transfers electrons to the negative atom.
In this question, Magnesium Sulfide, MgS is a compound whose atoms are held together by ionic bonds. The magnesium ion (cation) transfers its two valence electrons to the sulfur ion (anion) to form the stable MgS.
