Answer:

The information that can be used to determine which mixture has the higher proportion of KCl IS INFORMATION ABOUT THE MASS OF CHLORINE IN EACH MIXTURE, THIS INFORMATION CAN BE OBTAINED BY USING THE LAW OF DEFINITE PROPORTION.

Explanation:

The law of definite proportion states that the chemical composition by mass of a chemical compound is always constant. For instance, a chemical compound that is made up of two elements will always contain the same proportions of the constituent elements regardless of the quantity of chemical that was used.

Using the law of definite proportion, we can determine the proportion of sodium and chlorine in NaCl and the proportion of potassium and chlorine in KCl if the mass of chlorine that was used is known. Based on the results obtained, one can easily determine the mixtures that has higher proportion of KCl.

Answer:

The mass of  Cl  in each mixture

Explanation:

With the amount of Chlorine in the mixture, you can figure out the amount of Potassium and Souium to see which is more.

What would the result be of adding one proton to an atom​
GREYUIT [131]

Answer:Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium and thats your answer

A container of compressed hydrogen with a fixed volume has a pressure of 13.0 atm at a temperature of 20.0 °C. If its temperatur
nevsk [136]

Answer:

P₂ = 16.6 atm

Explanation:

Given data:

Initial pressure = 13.0 atm

Initial temperature = 20.0°C (20+273 = 293 K)

Final temperature = 102.0°C (102+273 =375 K)

Final pressure = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

13.0 atm / 293 K =  P₂/375 K

P₂ = 13.0 atm × 375 K / 293 K

P₂ = 4875 atm. K /293 K

P₂ = 16.6 atm
