Hey there!
For this we can use the combined gas law:
We are only working with pressure and temperature so we can remove volume.
P₁ = 2 atm
T₁ = 27 C
P₂ = 2.2 atm
Plug these values in:
Solve for T₂.
Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.
Hope this helps!
Answer:
1). Scientific
2). Plating the diluted bacteria on media that supports the growth of only living micro organisms. Statistically accurate.
Answer:
This done such that when a reaction is in equilibrium and disturb by and external force which would prevent its completion its adjust so as to offset that external force and still go on to completion
When light passes from one transparent object, this is called refraction
If every oxygen ion is combined with an aluminium ion has a charge of -2,the charge of each aluminum ion would be -3.
Uncharged Aluminum atom must need to lose it's electrons,in order to form the bond with oxygen which has vacant orbitals
ion
atom that has a positive or negative charge because it lost or gained one or more electrons
chemical bond
the attractive force that holds atoms or ions together
ionic bond
a chemical bond in which one atom loses an electron and the other atom gains electrons to form ions
chemical formula
a combination of chemical symbols and numbers to represent a substance
covalent bond
bond formed by the sharing of electrons between atoms
