when solid calcium chloride is left uncovered, the mass of the sample gradually increases. explain why this might be happening
Answers
Anhydrous calcium chloride will dissolve if exposed to air because it will absorb enough water from the atmosphere.
Briefing:
After a short while, you will have a clear liquid pool rather than a white lump. Because anhydrous calcium chloride is a deliquescent substance, air exposure causes it to become colourless. Even though they either release or absorb energy, calcium chloride and baking soda both dissolve in water and undergo physical changes. (If the water evaporated, the solids may be recovered.) Chemical changes result in the creation of calcium carbonate, carbon dioxide, and carbonic acid. Rusting is prevented by anhydrous calcium chloride's ability to absorb the water vapour in the test tube. It is therefore employed as a drying agent.

A sample of an unknown compound is vaporized at 130. °C. The gas produced has a volume of 960. ML at a pressure of 1. 00 atm, and it weighs 3. 99 g. Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound
Answers
The Ba gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound.
Which is an ideal gas?
Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly. Or Ideal gas is gas which follows all the gas laws at all temperature and pressure.
Briefing:
Since the gas in this situation acts optimally, we can use the equation below to calculate the moles under the given circ*mstances:
PV = nRT
n = 1.00 atm * 0.960 L / 0.8206 atm * l /atm * K / (130 + 273K )
n = 0.0029 mol
Now that we know how to calculate a compound's molar mass by dividing its mass by its mass, we can find its molar mass as follows:
MM = 3.99 g / 0.0029 mol
MM =137.5 g/mol
So probably, the gas may be Ba.(Barium)

Answers
No, because the statue has deteriorated and become discolored. The fact that the statue was already tarnished indicates that weathering has already taken place on the material.
Explain about the Chemical weathering?
Chemical weathering is the process through which rock interacts with mineral solutions to alter the composition of the rock. In this procedure, water and minerals combine to produce a number of chemical reactions and change the rocks.
Rust, which develops by oxidation, and acid rain, which results from the dissolution of rocks by carbonic acid, are two instances of chemical weathering. Rocks and minerals deteriorate through other chemical weathering processes including dissolution to create soil.
The process of chemicals in rainwater modifying the minerals in a rock is known as chemical weathering. Rainwater becomes somewhat acidic when carbon dioxide from the air is dissolved in it. Weathering can result from a reaction between rainwater and the minerals in the rock.

What is electronegativity ?
The term "electronegativity" refers to an atom's capacity to attract electrons, either positive or negative. It regulates how the shared electrons are distributed among the two or more atoms in a bond. An atomic will aggressively pull electron from its bonds only if electronegativity is high.
What causes an increase in electronegativity?
As you traverse a period in the chemical elements from left to right, the electron affinity of atoms rises. The reason for this is that when you move rom left to right along a time, the nuclear charge rises faster than the particle loading, increasing the atoms' attraction to the valence electrons.

Answers
Taking into account the reaction stoichiometry, 16.611 grams of Na₂CO₃ are necessary to completely react with 17.3 g of CuCl₂.
Reaction stoichiometry
In first place, the balanced reaction is:
Na₂CO₃ + CuCl₂ → CuCO₃ + 2 NaCl
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Na₂CO₃: 1 moleCuCl₂: 1 moleCuCO₃: 1 moleNaCl: 2 moles
The molar mass of the compounds is:
Na₂CO₃: 129 g/moleCuCl₂: 134.45 g/moleCuCO₃: 123.55 g/moleNaCl: 58.45 g/mole
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
Na₂CO₃: 1 mole ×129 g/mole= 129 gramsCuCl₂: 1 mole ×134.45 g/mole= 134.45 gramsCuCO₃: 1 mole ×123.55 g/mole= 123.55 gramsNaCl: 2 mole ×58.45 g/mole=116.9 grams
Mass of CuCl₂ required
The following rule of three can be applied: If by reaction stoichiometry 134.35 grams of CuCl₂ react with 129 grams of Na₂CO₃, 17.3 grams of CuCl₂ react with how much mass of Na₂CO₃?
mass of Na₂CO₃= (17.3 grams of CuCl₂× 129 grams of Na₂CO₃)÷ 134.35 grams of CuCl₂
mass of Na₂CO₃= 16.611 grams
Finally, 16.611 grams of Na₂CO₃ is required.

Answers
Three nonmetal atoms that, when bonded covalently, have a neon electron configuration are carbon, oxygen and fluorine, respectively.
The electronic configuration of carbon is 1s²2s²2p². It requires 4 electron to achieve a neon electron configuration. For example, in carbon dioxide, when carbon is bonded with two oxygen atoms, it shares its two electron pairs with the oxygen atom and forms a double covalent bond between C and O.
In the water (H₂O) molecule, the electronic configuration of oxygen is 1s²2s²2p⁴. The oxygen is central atom and it is bonded with two hydrogen atoms to achieve a neon electronic configuration, and it forms bent shape water molecule.
In hydrogen fluoride, fluorine has the electronic configuration 1s²2s²2p⁵, and it requires one electron to achieve neon electronic configuration. When fluorine is bonded with hydrogen(H), it forms single covalent bond.

Typically, the actual yield is lower than the theoretical yield because few reactions complete (i.e., are not 100% efficient) or because not all of the product in a reaction is collected. It is also conceivable for the real yield to exceed the theoretical yield.
What is theoretical yield ?
Theoretical yield is what would be obtained if 100% of the reaction was completed and no product was wasted in any way; however, procedures are not this efficient. Everything is dependent on the experimenter's precision and the reaction. Some reactions are reversible, meaning that less than 100% of the reaction proceeds to completion; some reactions do not go to completion because they require a large amount of energy or additional time, for example.

When moving from left to right across a period of the periodic table, the elements become less metallic.
Metallic luster, a bright appearance, high density, high thermal conductivity, and high electrical conductivity are physical characteristics connected to metallic character. The majority of metals are ductile and malleable, allowing for deformation without breaking. There are many thick and hard metals.
Metallic properties in the periodic table grow down groups and diminish from left to right across periods. Metal reactivity increases down groups and declines across periods from left to right. Indicators of nonmetallic properties rise from left to right and fall down groupings.
As an element's propensity to lose electrons declines, its metallic nature also lowers. Additionally, travelling from left to right in the periodic table increases the non-metallic character since an element's propensity to receive electrons increases with an increase in effective nuclear charge.

Answers
The molar mass of given acid H₂X is 85.1g/mol
Mass of the H₂X = 0.1873 grams
Molarity of NaOH = 0.1052 M
Thus, the balanced equation
H₂X (aq) +2 NaOH (aq) → Na₂X (aq) + 2H₂O(l)
Calculating moles of NaOH
For 1 mol H₂X we need 2 moles NaOH to produce 1 mole of Na₂X and 2 moles of H₂O
For 0.0022 moles of H₂X we need 0.0044 moles of NaOH
Volume of the NaOH = moles of NaOH / molarity of NaOH
Volume of the NaOH = 0.0044 moles / 0.1052 M
Volume of the NaOH = 0.04189 L = 41.89 mL
We just need 41.8 mL of NaOH
Since number of moles of H₂X is 0.0022
Number of moles= Mass/ Molar mass
0.0022= 0.1873/ Molar mass
Molar mass= 0.1873 / 0.0022
