Alja [10]

Answer:

The value of the gas equilibrium constant Kp is 18.3

Explanation:

Step 1: Data given

Kp= Kc(RT)^Δn

Temperature = 298 K

Kc = 18.3

Step 2: The balanced equation

C₄(s) + 4 O₂(g) ⇌ 4 CO₂(g)

Step 3: Calculate Kp

Kp= Kc(RT)^Δn

⇒with Kp = the gas equilibrium constant =  TO BE DETERMINED

⇒with Kc = the equilibrium constant = 18.3

⇒R = the gas constant = 0.08206 L* atm/mol*K

⇒T = the temperature = 298 K

⇒Δn = mol gas phase product – mol gas phase reactant = 4-4 =0

Kp = 18.3 * (0.08206*298)^0

Kp = 18.3 * 1

Kp = 18.3

The value of the gas equilibrium constant Kp is 18.3

A. 207 kJ<br> B. 4730 kJ<br> O C. 9460 kJ<br> O D. 414 kJ
slavikrds [6]

Answer:

C = 9460 Kj

Explanation:

Given data:

Mass of copper = 2kg

Latent heat of vaporization = 4730 Kj/Kg

Energy required to vaporize 2kg copper = ?

Solution:

Equation

Q= mLvap

by putting values,

Q= 2kg ×  4730 Kj/Kg

Q = 9460 Kj

Which statement describes the relationship between the scientific method in the scientific process
Oksana_A [137]

Answer: The methodology is the science that addresses these issues.

Explanation:

There are several steps to exploring to obtain valid scientific results. The scientific method is one of those elements. The scientific method involves specific steps that need to be taken to begin the scientific process adequately. By the scientific method, we also mean the hypothesis or assumption that needs to be put in the paper to try to defend it later and in fact. By scientific process, we suggest the following steps we take after evaluating a hypothesis. The scientific method is the very making of a particular scientific work, that is, its central part.
