Considering the definition of the law of conservation of matter, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).
Law of conservation of matterThe law of conservation of matter holds that, within a closed system, the amount of matter involved in a chemical reaction is constant, meaning a closed system means an environment that isolates the components involved in the reaction from the outside.
In other words, this law establishes that the mass of the reactants consumed is equal to the mass of the products obtained, even though they have been transformed into each other.
In other words, the law of conservation of matter states that matter is neither created nor destroyed during a chemical reaction, it is only transformed.
SummaryIn summary, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

A sample is left on the desk over several hours. On examination, the crystals appear moist, andliquid is forming around them. The compound is classified as:
a. Stableb.
b. Deliquescent
c. Efflorescentd.
d. Hygroscopic
Answers
Answer:
c. Efflorescent
Explanation:
Some hydrated salts, when exposed to the atmosphere, give off part of all of their water of crystallization spontaneously to form a lower dehydrated or anhydrous salt. Such salts are known as efflorescent and the phenomenon is called Efflorescence.
Efflorescence occurs when the hydrate's aqueous vapor pressure is greater than the water vapor's partial pressure in the air. For example, because the vapor pressures of washing soda (Na2CO3·10H2O) and Glauber's salt (Na2SO4·10H2O) normally exceed that of the water vapor in the atmosphere, these salts effloresce (i.e., lose all or part of their water of hydration), and their surfaces assume a powdery appearance.

H20)
Answers
Answer:
31.5 moles
Explanation:
Volume of H2O = 0.567 L
Number of mole of H2O =.?
Next, we shall convert 0.567 L to millilitres (mL). This can be obtained as follow:
1 L = 1000 mL
Therefore,
0.567 L = 0.567 L × 1000 mL / 1 L
0.567 L = 567 mL
Thus, 0.567 L is equivalent to 567 mL.
Next, we shall convert 567 mL to grams (g). This can be obtained as follow:
1 mL of H2O = 1 g
Therefore
567 mL of H2O = 567 g of H2O
Finally, we shall determine the number of mole in 567 g of H2O. This can be obtained as follow:
Mass of H2O = 567 g
Molar mass of H2O = (2×1) + 16
= 2 + 16 = 18 g/mol
Mole of H2O =?
Mole = mass /Molar mass
Mole of H2O = 567 /18
Mole of H2O = 31.5 moles

A) Pb < P < Ba
B) Ba < P < Pb
C) Pb < Ba < P
D) Ba < Pb < P
Answers
Answer:
D) Ba < Pb < P
Explanation:
Barium (Ba): 5,2117
Lead (Pb): 7,4167
Phosphorus (P): 10,4867
Increasing order of ionization energy:
Ba < Pb < P
Electronic configurations of given elementsPb: [Xe] 6s² 4f¹⁴ 5d¹⁰ 6p²
P: [Ne] 3s² 3p³
Ba: [Xe] 6s²
All the given elements have stable half-filled subshells. But phosphorus has the smallest atomic size among them, so it will have the lowest tendency to remove an electron from its valence shell and hence will require the highest amount of ionization energy. Barium has a higher atomic size than lead, therefore it has lower ionization energy than lead.How are ionization energy and atomic size related?The force of attraction is stronger when the electron is closer to the nucleus, and as a result, more energy is needed to overcome this attraction and remove the electron.Therefore, the ionization energy increases with decreasing radius and vice versa.Learn more about trends of ionization energy here:

What type of bond is present between two atoms of zinc in a nickel

Answer:
Pure covalent
Explanation:
To know the type of bond between two atoms you must find the electronegativity difference of them:
If electronegativity difference is:
< 0.4: Pure covalent.
Between 0.4 and 1.8: Polar covalent.
> 1.8: Ionic.
The electronegativity of Zn is 1.65 and Ni is 1.91. Electronegativity difference is:
1.91 - 1.65 = 0.26
That means the type of bond is:
