Your answers are correct. I love the Universal formula.
Answer:
The correct answer will be "18.25 g".
Explanation:
The given values are:
Specific heat,
C = 0.45 J/g･°C
Heat involved,
q = 801 J
Temperature,
ΔT = 120.0°C-22.5°C
= 97.5°C
As we know,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Answer;
Solvent
Explanation;
-A solution is a homogeneous mixture that is made of two or more substances. In other words, It is a mixture in which one of the substances dissolves in the other. The substance which dissolves is called the solute while the substance that dissolves the solute is called the solvent.
-In a solution of a carbonated beverage, water acts as the solvent which dissolves the components added as solute to make the beverage. These components include sugars and other types of salts such as sodium citrate, all dissolved in water.
This is a physical change, you can turn the current off not changing something permanently such as mixing cake batter you cant delude the eggs and flour so its would be physical.
These gases very rarely react, with others and also noble gases are odourless and colourless.
Explanation:
- Noble gases will not react with anything so that is the reason why they are known as an inert gas.
- Noble gases are present in group 18 on the periodic table and following the rule of the octet which is they completed their orbital by s2p6 which is the highest energy level.
- Most elements are discovering through their reactivity with the other elements, commonly with oxygen. In the case of a noble gas, it is difficult for a scientist to work with the gases which have very less or no chemical property in terms of their reactivity.
