How many half lives have elapsed?
actually the formula is like this
A=P(1/2)^(t/h)
P=iniital amount
t=time
h=half life
A=final amount
so
hmm, percent
so P=1 then
A=1(1/2)^(144.6/24.1)
A=1(1/2)^6
A=1/64
A=0.05625
so 5.625% is left
H2O- H+ O2-. YES HYDROGEN ARE MADE UP OF HYDROGEN AND OXYGEN ATOMS
Answer:
Because covalent bonds are strong, diamond contains many covalent bonds. As high temperatures are required to break such strong bonds, diamond melts at a very high temperature.The three-dimensional arrangement of carbon atoms, held together by strong covalent bonds, makes diamond very hard. ... Diamond has a very high melting point because a large amount of energy is needed to overcome the many strong covalent bonds.
Milk (lowest acidity) < Coffee < Orange juice < Soda pops < vomit < Battery acid (highest acidity)
explanation :
pH values of all :
battery acid pH = 1.0
vomit pH = 2.0
soda pop pH = 2.5
orange juice pH = 3.5
coffee pH = 5.0
milik pH = 6.5
pH value is lesser acidity is more . high pH indicate lesser acidic nature
I’m pretty sure it’s C neutral
