Taking into account the definition of reactivity, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.
Reactivity is a measure of the probability that a chemical species will participate in a chemical reaction to form chemical bonds.
In other words, the reactivity of a chemical element is the tendency that this element has to combine with others.
For elements that behave like metals, this trend is directly related to the ease with which they lose their valence electrons.
Valence electrons are those electrons farthest from the nucleus of the atom. These electrons are easier to remove because they are the least attracted to the nucleus. Thus, less and less energy is needed to start these valence electrons, so they can commonly participate in the formation of chemical bonds.
In other words, as the size of the metal atoms in a group increases, so does their reactivity.
Then, the correct option is the first option: Metals on the right have more valence energy levels, so the ability of the nucleus to attract electrons is reduced.

A. High temperatures are best to minimize the solubility.
B. High temperatures are best to maximize the solubility.
C. Low temperatures are best to minimize the solubility.
D. Low temperatures are best to maximize the solubility.
Please answer and thankyou!
Carbonated beverages contain dissolved carbon dioxide gas. Low temperatures are best to minimize the solubility. option C is correct.
Drinks that have carbon dioxide dissolved in the water are referred as carbonated beverages. The presence of this gas causes the liquid to froth.
Carbonation takes place by applying pressure. Spring water, beer and soda, and pop are a few examples of carbonated beverages. When carbon dioxide is absorbed in a liquid, for example spring water, it absorbs Carbon dioxide from the subsurface. It can also happen naturally. Beer is example of a naturally carbonated beverage as the brewing process produces carbon dioxide soda .
Thus option C is correct.

A sample of Element X is found to contain 82.15% of isotope type 1 (84.9118 amu)
and 17.85% of isotope type 2 (86.9092 amu). Calculate the average atomic
mass.
Answer:
Have you gotten your answer yet?
The average atomic mass of element X is 85.26 amu.
To calculate the average atomic mass of Element X, we need to take into account the abundance of each isotope and its respective atomic mass.
First, let's assign variables to the abundance and atomic mass of each isotope:
- Isotope 1: abundance = 82.15%, atomic mass = 84.9118 amu
- Isotope 2: abundance = 17.85%, atomic mass = 86.9092 amu
To calculate the average atomic mass, we can use the following formula:
average atomic mass = (abundance₁ ×atomic mass₁) + (abundance₂ ×atomic mass₂)
Substituting the values:
average atomic mass =
[tex]\dfrac{82.15\times84.9118}{100}+\dfrac{17.85\times86.9092}{100}\\=85.26 \ \rm{amu}[/tex]
Thus, average atomic mass of element X is 85.26 amu.

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{2.4 \times {10}^{21} }{6.02 \times {10}^{23} } \\ = 0.003986[/tex]

How many moles of HCl can be produced from 0.207 g of SOC12 SOC12(1) + H2O(1) = SO2(g)+ 2HCl(g)
Answer:
.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂
Explanation:
The balanced reaction is:
SOCl₂ + H₂O ----> SO₂ + 2 HCl
By stoichiometry of the reaction they react and produce:
SOCl₂: 1 mole
H₂O: 1 mole
SO₂: 1 mole
HCl: 2 mole
Being:
S: 32 g/mole
O: 16 g/mole
Cl: 35.45 g/mole
H: 1 g/mole
the molar mass of the compounds participating in the reaction is:
SOCl₂: 32 g/mole + 16 g/mole + 2*35.45 g/mole= 118.9 g/mole
H₂O: 2*1 g/mole + 16 g/mole= 18 g/mole
SO₂: 32 g/mole + 2*16 g/mole= 64 g/mole
HCl: 1 g/mole + 35.45 g/mole= 36.45 g/mole
Then, by stoichiometry of the reaction, the following amounts of mass react and are produced:
SOCl₂: 1 mole* 118.9 g/mole= 118.9 g
H₂O: 1 mole* 18 g/mole= 18 g
SO₂: 1 mole* 64 g/mole= 64 g
HCl: 2 mole* 36.45 g/mole= 72.9 g
Then the following rule of three can be applied: if by stoichiometry of the reaction 118.9 grams of SOCl₂ produce 2 moles of HCl, 0.226 grams of SOCl₂ how many moles of HCl do they produce?
moles of HCl= 3.80*10⁻³
3.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂
