Answer : The correct options are, 1 atm pressure and 273 K temperature.

Explanation :

STP : STP stands for standard temperature and pressure.

At STP,

The temperature is, 0^oC or 273K or 32^oF

The pressure is, 1atm or 101.325kPa  or 760mmHg

The volume is, 22.4 L

Hence, the correct options are, 1 atm pressure and 273 K temperature.

Standard Temperature and Pressure (STP) conditions are:


1) 760 mmHg

2) 1 atm

3) 273.15 K (0 C, 32 F)


I'm not too sure if you mistyped your first bullet, but if you did not, it is not included as an STP condition - it must be millimeters.

What is the electron configuration of ClS2?
miss Akunina [59]

Answer:Chlorine

Explanation:The distribution of electrons in an atom is called as Electronic Configuration. Formula 2n2 helps in the determination of the maximum number of electrons present in an orbit, here n= orbit number. The formula helps in determination of arrangement of electrons and is known as “Bohr Bury Schemes.”

Breaking an object such as a mirror is an example of physical change, chemical change,physical reaction, chemical reaction
dangina [55]

Answer:

option A= Physical change

Explanation:

physical change:

" It is a change in which no new substance is formed"

Breaking of object like glass is the example of physical change because it is not change into another object. It effect the form of object but can not change the chemical composition.

Chemical changes:

" it is a change in which one substance is converted into new product through chemical reaction".

During the chemical changes the types and the number of atom remain same but their arrangement changed.

for example: burning of wood, baking of cake, digesting food, resting of iron etc.

Physical reaction:

" physical reaction occur during the molecular rearrangement. There is no chemical change occur"

In this type of changes no bonds are break to form new bonds, for example boiling point.

Chemical reaction:

" chemical reaction occur when molecules are chemically react with each others and bonds formation and breaking is also occur"

Question 3 (1 point)
Hoochie [10]

Answer:

50 mol

Explanation:

Mass of methane = 800 g

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

CH₄ + 2O₂      →      CO₂ + 2H₂O

Number of moles of methane:

Number of moles = mass/molar mass

Number of moles = 800 g/ 16 g/mol

Number of moles = 50 mol

Now we will compare the moles of methane and carbon dioxide from balanced chemical equation.

                CH₄        :         CO₂

                   1           :          1

                 50          :        50
