Take note of the reaction formula which is PCl5=Cl2+PCl3.
The Keq = [Cl2] * [PCl3] / [PCl5]=2.24*10^-2.
For the reason that the volume is 1 liter, the concentration of Cl2 will be computed through: <span>(2.24 * 10^-2) * 0.235 / 0.174 </span> = 0.0303 mol/L is the answer.
Answer: 9 days
Explanation:
Let the rate of Leaf growth <em>r</em> be defined as, 
= 
where <em>A</em> is initial area of the leaf, <em>A1</em> is the final area of the leaf and<em> t</em> is the time taken for the increase in Area.
- Express the proportional relationship in equation.
Given that rate of leaf growth, r is proportional to the surface area of the leaf A. we have r ∝ A.
r = kA, where k is the rate constant.
therefore, k = 
when A = 2
, A1 = 3
so k = 
= 
÷ 2
= 0.33 ÷ 2
k = 0.167
- After calculating the rate constant k, we then find the time t when A1 is 5
- we have r = k × A1 =
so, 0.167 × 2 = 
0.33 = 
.
t = 3/0.33
Therefore, t = 9 days.
Answer:
Unknown
Explanation:
By definition, we can't observe what's inside there, because no light – no information of any kind – can escape a black hole. But astrophysical theories suggest that, at the core of a black hole, all the black hole's mass is concentrated into a tiny point of infinite density. This point is known as a singularity.
Answer:
The total Mechanical energy will be zero
Explanation: Escape velocity is the velocity required by a free object in order to overcome the impact of the force of gravity. The total mechanical energy of an object is the total energy possessed by an object which includes its kinectic and potential energy.
since the object is moving at an escape velocity which is 11.2m/s the object will be assumed to be weightless
Etotal = kinetic energy + potential energy
kinetic energy= 1/2*M*V*V
Potential energy=MGH
Etotal=1/2*0*11.2*11.2+0*0*0
Etotal=0+0
Etotal=0.
The EMT must assume that any unwitnessed water-related incident is accompanied by potential spinal damage.
<h3>What is spinal damage?</h3>
- Nerves or the spinal cord in any way damaged at the end of the spinal canal.
- A rapid strike or cut to the spine can cause a traumatic spinal cord damage.
- Below the damage site, a spinal cord injury frequently results in a lifelong loss of strength, feeling, and function.
- A lot of people with spinal cord injuries may lead productive, independent lives with the help of rehabilitation and assistive technology.
- Symptom-reducing medications and spinal stabilisation surgery are used as treatments.
- Herniated discs are among the common injuries and diseases of the spine. Stenosis of the lower back and Scoliosis are others.
- After taking part in a rehabilitation programme, over 80% of people with incomplete spinal cord injury (SCI) can walk again.
