Do not conduct electricity as solids. how can you use salt to conduct electricity
Answer:
Model A
Explanation:
Model A represents an atom that is more reactive than the others represented.
Valence electrons actually determine the reactivity of elements. They also determine the properties of elements.
Elements with one valence electron are highly reactive because they need low energy to remove them. They can either gain more electrons to become stable or they share/give out their electrons.
Therefore, Model A is the correct answer because it has one valence electron and its valence electron is farther from the nucleus thereby this makes it more reactive.
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10.
Answer:
no
Explanation:
A Rhinoceros is a consumer because it eats plants, which are producers.
Chlorocyclohexane has the molecular formula of C₆H₁₁Cl. We can use simplified atomic masses for each atom to find the total molecular weight.
6C = 6 x 12 g/mol = 72 g/mol
11H = 11 x 1 g/mol = 11 g/mol
1Cl = 1 x 35 g/mol = 35 g/mol and 1Cl = 1 x 37 g/mol = 37 g/mol.
We can add the masses of each atom to get two different molar masses, one for each chlorine isotope.
72 + 11 + 35 = 118 g/mol with ³⁵Cl.
72 + 11 + 37 = 120 g/mol with ³⁷Cl.
The two molecular ions will therefore be 118, 120.
The relative percentages of each molecular ion will be solely dependent on the ratio of chlorine isotopes which we are told is roughly 76:24. Therefore, the ratio of molecular ions is:
118, 76 %.
120, 24 %.
