Answer:
Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
Answer:
Mohammed has less kinetic energy
Explanation:
m=Kg
V= m/s
KE= kinetic energy = J
the way you work out the answer is:
KE = 1/2 × m × v squared
No, firstly bc stainless steel and carbon steel mixed with different things, high-density metals and carbon.
High-density metals and carbon both has different density which will affect the steel when they combined with iron. So it cant be the same.
Answer:
Percent error = 2.8
Explanation:
Given data;
Actual value = 17.9 cm
Measured value = 17.4 cm
Percent error = ?
Solution:
Formula:
Percent error = [actual value - measured value / actual value] × 100
Now we will put the values in formula:
Percent error = [17.9 cm - 17.4 cm / 17.9 cm] × 100
Percent error = [0.5 cm /17.9 cm] × 100
Percent error = 0.028 × 100
Percent error = 2.8
I think the correct form of the equation is given as:
a = a0 * (0.9)^t
where t is an exponent of 0.9 since this is an
exponential decay of 1st order reaction
Now to solve for the half life, this is the time t in
which the amount left is half of the original amount, therefore that is when:
a = 0.5 a0
Substituting this into the equation:
0.5 a0 = a0 * (0.9)^t
0.5 = (0.9)^t
Taking the log of both sides:
t log 0.9 = log 0.5
t = log 0.5 / log 0.9
t = 6.58 years
Answer:
half life = 6.58 years
