The balanced chemical equation is 2 AlI₃ + 3 HgCl₂
2 AlCl₃ + 3 HgI₂ for the given chemical reaction.
<h3>What is chemical equation?</h3>
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:
Displacement in Y direction is 0.434 m
Explanation:
initial velocity of the puck is 2.35 m/s at -22 degree
so here it is given as
![v_i = 2.35 cos22 \hat i - 2.35 sin22 \hat j](https://tex.z-dn.net/?f=v_i%20%3D%202.35%20cos22%20%5Chat%20i%20-%202.35%20sin22%20%5Chat%20j)
![v_i = 2.18 \hat i - 0.88 \hat j](https://tex.z-dn.net/?f=v_i%20%3D%202.18%20%5Chat%20i%20-%200.88%20%5Chat%20j)
final velocity is given as 6.42 m/s at 50 degree
so we have
![v_f = 6.42 cos50 \hat i + 6.42 sin50\hat j](https://tex.z-dn.net/?f=v_f%20%3D%206.42%20cos50%20%5Chat%20i%20%2B%206.42%20sin50%5Chat%20j)
![v_f = 4.13 \hat i + 4.92\hat j](https://tex.z-dn.net/?f=v_f%20%3D%204.13%20%5Chat%20i%20%2B%204.92%5Chat%20j)
now displacement in Y direction is given as
![\Delta y = \frac{v_f + v_i}{2}t](https://tex.z-dn.net/?f=%5CDelta%20y%20%3D%20%5Cfrac%7Bv_f%20%2B%20v_i%7D%7B2%7Dt)
![\Delta y = \frac{-0.88 + 4.92}{2} (0.215)](https://tex.z-dn.net/?f=%5CDelta%20y%20%3D%20%5Cfrac%7B-0.88%20%2B%204.92%7D%7B2%7D%20%280.215%29)
![\Delta y = 0.434 m](https://tex.z-dn.net/?f=%5CDelta%20y%20%3D%200.434%20m)
Answer:
Because the uncontrolled and unreasonable use of energy resources in the past few decades has led to the depletion of conventional type of resources. Although, measures are taken at the government levels to control the energy consumption, these attempts only meet with little success. Public awareness is the only way to successfully deal with this problem.
Explanation:
Answer:
A low difference in the concentration of the molecule across the media
Explanation:
Diffusion is a type of passive transport where the molecules move in the influence of concentration gradient of diffusing molecules i.e. from the higher concentration region to the lower concentration region. There are some factors which affect the rate of diffusion, these are written below -
- Mass of diffusing molecule - lighter molecules diffuse faster and heavier one diffuse relatively slower.
- Concentration gradient - rate of diffusion is higher if the difference in concentration of the diffusing particles is larger in the two regions.
- Distance traveled - molecules diffuse faster if they need to travel little distance during diffusion.
- Temperature - rate of diffusion will be greater at higher temperatures because the movement of diffusing molecules gets increased.
- Solvent density - rate of diffusion tend to be lower if the solvent has higher density.
Looking at these factors we can conclude that the second statement in the question tells about a negative impact regarding the diffusion because due to low difference in concentration across the two media, the rate of diffusion will be lower.
