Gonna have to go with A since two genes create a new one example is parents having a kid that’s how I understood it sorry if it’s wrong or I misunderstood
Answer:
Explanation:
pKa = 3.86
-log Ka = pKa
- log Ka = 3.86
Ka = 1 / ( 10^(3.86)) = 1.38 × 10⁻⁴
lactic → (H⁺) + lactate
but Ka ( equilibrium constant ) = ( H⁺) (lactate) / ( lactic acid)
when HCl dissociate, it forms
HCl → H ⁺ + Cl⁻
0.08 M of HCl will yield 0.08 M H⁺, lactate ion = 0.1 M
1.38 × 10⁻⁴ = (0.08) (lactate) / 0.1
(1.38 × 10⁻⁴ × 0.1) / 0.08 = lactate
lactate = 1.73 × 10⁻⁴
Answer:
O
Explanation:
O is in the red which says nonmetal
Answer:
Discovery of neutron
Explanation:
Until 1932, the atom was believed to be composed of a positively charged nucleus surrounded by negatively charged electrons, after successful discovery of electron by J.J. Thompson and proton by Ernest Rutherford.
In 1932, James Chadwick bombarded beryllium atoms with alpha particles.
As Chadwick had previously seen in experiment conducted by Frédéric and Irène Joliot-Curie, they had bombarded a sample of beryllium with alpha radiation.
Chadwick repeated the experiment and observed an unknown radiation, this showed no deflection what-so-ever.
He repeated this experiment by bombarding other materials, like helium, nitrogen and lithium,
Finally, Chadwick found that this radiation was composed of particles with a neutral electrical charge and had approximate mass of a proton.
This particle was then known as the neutron.
