According to Gay -Lussac's law, the pressure of the can if it is heated to 1270°C is 4295.53 mm Hg.
It is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.
The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .If a graph of pressure versus temperature is plotted it is a straight line which passes through the origin .
The equation is given as, P₁/T₁=P₂/T₂
On substitution of values as ,P₁=760 mm Hg,T₁=273 K,T₂=1543 K
P₂=1543×760/273=4295.53 mm Hg.
Thus, the pressure of gas is 4295.53 mm Hg if it is heated up to 1270°C.

NaCl, CH4, MgO and C6H12O6 are the empirical formula for four ionic compounds.
Empirical formula is defined as the chemical formula of a compound that gives the simplest proportions or ratios of the elements present in the compound but not the original numbers of atoms.
So we can conclude that NaCl, CH4, MgO and C6H12O6 are the empirical formula for four ionic compounds.

The empirical formula for the four ionic compounds are CaF₂ and V₂S₅.
The empirical formula represents the simplest ratio of the elements in a compound. To determine the empirical formula of an ionic compound, we need to find the ratio of the ions involved. Given Ca²⁺, V⁵⁺, F⁻, and S²⁻, we can combine these ions to form different compounds by balancing their charges. Taking Ca²⁺ and F⁻, we get CaF₂. For V⁵⁺ and S²⁻, we get V₂S₅. Therefore, the empirical formula for the four ionic compounds is CaF₂, V₂S₅.

Answer:
Iron has a standard electrode potential which is less than gold, which therefore means the gold is less reactive,
Answer:
The solution in the buret, during a titration is called titrant.
Explanation:
A titration is a useful process, that makes you know the concentration of a solution. A titrant solution (burette) is evaluated against a titrand to control the pH changes against the volume aggregate. Only a strong acid with a strong base, a strong base with a strong acid, a weak acid with a strong base and a weak base with strong acid are valued.
When the pH reaches the equivalence point, it is said that the normality of the acid by the milliequivalents, is equal to the basic normality by its milliequivalents. In conclusion, the entire base / acid became its conjugate pair.
To check this sudden change in pH, a substance is used, called Indicator that changes the color of the titrand (analyte).
In a titration analysis, the substance in the buret is called the 'titrant'. It is used to react with the analyte, the sample solution whose concentration we're measuring. The goal is to reach the endpoint, the point when a distinct visual change indicates that the titrant has completely reacted with the analyte.
In a titration analysis, the solution in the buret is called the titrant. This solution contains a known concentration of a substance. During a titration, this titrant is added incrementally to a sample solution, called the analyte, which contains the substance whose concentration is to be measured. The titrant and analyte undergo a chemical reaction of known stoichiometry.
By measuring the volume of the titrant solution needed to completely react with the analyte, scientists can calculate the concentration of the analyte. This point where the titrant has completely reacted with the analyte is termed the equivalence point of the titration. The process of adding the titrant is halted when a distinct change is visually detected in the solution - this could be a color change, for example. This is known as the end point.
