Octane has stronger London dispersion forces than ethane
Hi
Alpha decay is a type of radioactive decay.
So, when Alpha decay goes through a process called "radioactive process", two neutrons and two protons comes together and is ejected from the nucleus of a radioactive atom.
Hope this helped :)
This is because the minerals that make up the rocks form only at certain temperatures and pressures. At high temperatures or pressures, the elements will rearrange their crystal structure to form a different mineral. Graphite and diamond are two minerals that are both made entirely out of carbon.
Answer:
0.38dm³ or 38mL
Explanation:
Given parameters:
molarity of HCl = 5.5M
volume of Mg(OH)₂ = 85mL
molarity of Mg(OH)₂ = 1.22M
Unknown:
Volume of HCl solution = ?
Solution:
we have to adopt the mole concept to solve this problem.
Complete reaction equation:
2HCl + Mg(OH)₂ → MgCl₂ + 2H₂O
For a standard acid titrated against a standard base,
aA + bB → cC + dD
A is the acid, B is the base
since number of moles = C x V
C is the molarity
V is the volume
CₐVₐ / CₓVₓ = a / x
a = acid
x = base
85mL to dm³ = 0.085dm³
since the unknown is Vₐ,
let us make it the subject of the expression;
Vₐ = (a/x) x ( CₓVₓ/ Cₐ)
Va = = 0.38dm³
