Conduction is the transfer of thermal energy with no transfer of manner. It occurs when two materials touch; Conduction in gas is slower than in liquids and solids because the particles in a gas collide less often.
Answer: = 1.834 M
= 0.004 M
= 0.166 M
Explanation:
Initial concentration of = 0.15 M
Initial concentration of = 2.0 M
The given balanced equilibrium reaction is,
Initial conc. 2 M 0.15 M 0
At eqm. conc. (2-x) M (1-6x) M (x) M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
By solving the term 'x', we get :
= (2-x) = 2-0.166 = 1.834 M
= (1-6x) = 1-6(0.1660)= 0.004 M
= x = 0.166 M
Hope this helps! I found it when I searched your question.
Answer:
Complex System
Explanation:
Given that, a descriptive scientific investigation is one of the three main types of investigation which formulates and quantify the natural phenomenon. This natural phenomenon oftentimes involves Complex System, such as microscopic organisms, thereby, scientists often make observations to understand the interacting parts of this COMPLEX SYSTEM
Hence, the right answer is a COMPLEX SYSTEM
Answer:
16mL
Explanation:
Using the following formula;
CaVa = CbVb
Where;
Where
Ca = concentration/molarity of acid (M)
Va = volume of acid (mL)
Cb = concentration/molarity of base (M)
Vb = volume of base (mL)
According to the information provided in this question;
Ca (HCl) = 2M
Cb (NaOH) = 5M
Va (HCl) = 40mL
Vb (NaOH) = ?
Using CaVa = CbVb
Vb = CaVa/Cb
Vb = 2 × 40/5
Vb = 80/5
Vb = 16mL
