Only far from the Sun material condensed in the solar nebula, ice formed
After your first exposure to a pathogen, you have memory T cells that will remember the antigen of the pathogen son in the future if you would come in contact with the same pathogen your body will recognize it right away and be able to kill it much faster
Hydrocarbons are chains of C and H. C and H are held together by covalent bonds.
hydrocarbons are of three main types
alkanes - only single bonds between C atoms
alkenes - double bonds between C atoms present
alkynes - triples bonds between C atoms present
saturated hydrocarbons definition is when there are only single bonds present
from the given compounds
propane - only single bonds
propene - double bond
propyne - triple bond
propanal - double bond between C and O
only compound with single bonds is propane
answer is propane
Answer: after years of research if the evidence still supports a change the theory will be revised
Explanation:
I think that’s it
Answer:
The volume occupied by given molecules of carbon dioxide at STP is 55.86 L.
Explanation:
Where:
N = Number of particles / atoms/ molecules
n = Number of moles
= Avogadro's number
We have:
N = 
n =?
n = 2.4909 moles
Using ideal gas equation:
PV = nRT
where,
P = Pressure of carbon dioxide gas = 
(at STP)
V = Volume of carbon dioxide gas = ?
n = number of moles of carbon dioxide gas =2.4909 mol
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of carbon dioxide gas = 273.15 K (at STP)
Putting values in above equation, we get:
V = 55.86 L
The volume occupied by given molecules of carbon dioxide at STP is 55.86 L.
