Fe 3+ + SCN- --> FeSCN 2+
<span>.......Fe 3+ .......SCN-.........FeSCN 2+ </span>
<span>I.......0.04..........0.001.............. </span>
<span>C........-x...............-x............. </span>
<span>E.....0.04-x.....0.001-x...........x </span>
<span>Keq = 203.4 = x / (0.04-x)(0.001-x) </span>
<span>203.4 = x / (x^2 - 0.041x + 4x10^-5) </span>
<span>203.4x^2 - 8.34x + 0.00094 = x </span>
<span>203.4x^2 - 9.34x + 0.00094 = 0 </span>
<span>x = -0.0001M or 0.0458M </span>
<span>so, using your Keq, there would be no SCN- or Fe 3+ left.....all would be in the form of FeSCN 2+</span>
<u>The S.I unit for the given term:</u>
Mass is expressed in kilogram (kg)
temperature is expressed in kelvin (K)
Time is expressed in seconds (s)
Current is expressed in ampere (A)
<u>Explanation:</u>
<u>Current:
</u>
The current can be defined as the electric charge flow in the surface (means ratio of charge per unit time). It is measured in ampere (A)

<u>Temperature:
</u>
Kelvin (K), the general temperature unit in the international standard units system. The Kelvin scale is an absolute thermodynamic temperature scale that uses absolute zero, a temperature at which all thermal movements end with a classic description of thermodynamics.
<u>Mass:
</u>
Mass is both a feature of the objects weight and its resistance measurement to accelerate under the influence of pure force. The mass of the object also determines the gravitational force. The basic unit of mass is kilogram (kg)
<u>Time:
</u>
Time is the measurement of how much distance the objects takes to travel from one to another (speed). It is expressed in seconds (s).
Answer:
crystals
It's in my science book, my class just finished this chapter.
Answer:
2NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂
C₆H₇O₆⁻ + Cl⁻ -> Cl⁻ + C₆H₇O₆⁻
Explanation:
Here the reaction which is taking place is a double displacement reaction.
In this there is only an exchange of bonds and no chemical reaction.
Here the ions remain exactly the same
C₆H₇O₆⁻ + Cl⁻ -> Cl⁻ + C₆H₇O₆⁻
We can balance the skeletal equation
NaC₆H₇O₆ + CaCl₂ -> NaCl + Ca(C₆H₇O₆)₂
First we balance Chlorine atoms by writing 2NaCl
NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂
Now in order to balance Na atoms we make it 2NaC₆H₇O₆
2NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂
In this equation all atoms are balanced.
Answer:
Wind
Explanation:
Wind turbines make energy by the movement of the natural force on earth called 'wind' and renewable resources are resources that can be made from natural and environment-safe objects or things (e.g. Water, Geothermal Heat, The Sun, and Wind)
