Answer:
Explanation: Nickel is element number 28 on the period table with a mass number 58 or 60, it exist in two forms and the phenomenon is known as isotopy
Definition of Isotopy is simply a phenomenon whereby elements exist in various forms that have the exact same chemical properties but different atomic mass.
58-Ni has atomic number 28 because that's the number o the element on the periodic table. Proton number is the same as atomic number and same as electron number for a neutral element or element without charge.
Mass number = Proton number (P) + Neutron number (N)
58 = 28 + N
N= 58-28
N= 30
58-Ni has 28 has the atomic number, proton number and electron number because it is a neutral atom but the neutron is 30 as shown in the calculation above.
60-NI+2 has a contrasting figure because the element has a charge of +2
Mass number= Proton + Neutron
60 = 28 + N
N= 60 - 28
N= 32
Electron = Proton - Charge
28 - (+2)
28 - 2
Electron = 26
The number of electron in 60-Ni +2 differs from 58-Ni because of the number of charge
Electron number differs from proton number in any element with a charge.
Answer:1.34 ×10^-5
Explanation:
AgCl = (Ag+) (Cl-)
=(S)(S)
= S²
S stands for molar solubility
Ksp =S² = 1.80 × 10^ -10
S= √[1.80 × 10^ -10]
=1.34 × 10^-5
Answer:
Substrate
Explanation:
In biochemical sciences, a substrate is a substance that is acted upon by an enzyme to yield a product. Enzymes are known for catalyzing biochemical reactions. The substances that are usually worked with during this catalytic process are termed as SUBSTRATES.
Substrates, which are usually changed during the process, binds to the active site on the enzyme and form an enzyme-substrate complex.
According to this question, pyruvate is converted to lactate in a reaction that is catalyzed by the enzyme lactate dehydrogenase. This means that the compound on which the enzyme works, pyruvate, is called the SUBSTRATE.
