Answer:
the raising atomic number
Explanation:
Elements are listed on the periodic table according to their atomic number.
Answer: Option (B) is the correct answer.
Explanation:
Isotopes are the substances or species that contain same number of protons but different number of neutrons.
As it is known that atomic number means the total number of protons present in an atom. Hence, this also means that in isotopes atomic number of the species is same.
For example, isotopes of hydrogen are
,
, and
.
Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons.
Thus, we can conclude that the statement isotopes of the same element have the same atomic number but differ in their atomic masses, is correct.
Answer:
Develop systems that track and predict harmful algal blooms
Explanation:
In Massachusetts, scientists are experimenting with a sensor that can identify three types of dangerous microscopic algae by their genetic material and offer an early warning when they are detected in the water.
Which situation is an example of internal conflict
Answer:
The answer to your question is: HCl = 58.44 g
Explanation:
To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.
That means that, the mass of the reactants must be equal to the mass of the products.
Process
Sodium (Na) + Chlorine (Cl) ⇒ Sodium chloride (HCl)
22.99 g 35.45 g x
22.99 + 35.45 = HCl
HCl = 58.44 g
