Decrease in area Explanation:
additional heat for an exothermic reaction Explanation: Any change of equilibrium is studied according to the principle of Le-Chatelier. This principle states that if there is a change in the reaction variables, the equilibrium will shift in the direction of minimizing the effect. 1. Addition of a catalyst The role of the catalyst is to quickly reach equilibrium without disturbing the state of equilibrium. Therefore, the addition of catalyst will not alter the equilibrium of the reaction. 2. Increase the concentration of reactants If the concentration of reactants is increased according to Le-Chatelier’s principle, the equilibrium will shift in the direction where the concentration of reactants decreases. Therefore, the equilibrium will shift forward and the rate will increase. 3. Decreasing Product Concentration If the product concentration decreases, according to Le-Chatelier’s principle, the equilibrium will shift in the direction that the product concentration increases. Therefore, the equilibrium will shift forward and the rate will increase. 4. Additional heat to an exothermic reaction If the temperature in the exothermic reaction increases, according to the Le-Chatlier principle, the equilibrium will shift in the direction in which the additional heat is consumed, i.e. in the direction endothermic shrinkage. Thus, the equilibrium will shift in the opposite direction and the rate will decrease. Therefore, the equilibrium will shift to the left and therefore the rate will decrease.
Option (B) is the correct answer. Explanation: When we dilute vinegar, there will be a decrease in vinegar particles. That is, there will be a decrease in the number of solute particles in the solvent. This way, there will be fewer collisions between the vinegar and the sodium hydroxide. Therefore, there will be a decrease in the reaction rate. So, we can conclude that, among the given options, diluting vinegar would slow down the reaction rate between vinegar and sodium hydroxide is the right option.
B A decline in lower investment spending, also, reduction of taxes and import tariffs can encourage a country’s production and are investments that the government should make to strengthen the economy.
Decrease of the surface of the solid in the liquid. Explanation: I don’t know how to explain this without using. An example. So there it is: if you soaked the bread in water, the bread would be completely soaked if you soaked the whole thing, but if you only left part of the bread in water, it would take longer for water soaks all the way into it. The amount of surface area he can touch anything that causes the solid to dissolve determines how quickly the whole thing dissolves.
Answer 6
The correct answer to the next question will be option E (Tilt the camera back so the plane appears to be on the yz axis now). Explanation: The field given is: ⇒ The field given above has a field E perpendicular to something like the plane. So, ⇒ We know that the value of “Cos 90°” is zero. ⇒ The other choices given are not related to the given circumstances. Therefore, option E seems to be the correct answer.
Answer 7
The correct answer would be B. Decrease in area. Explanation: It would decrease because the surface dissolves, therefore the surface decreases.
When a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always directed towards the center of the Earth. … At the right speed, it will move around the Earth in a circular motion. This type of movement and the path taken by a satellite is called an orbit.
Friction occurs between two surfaces in contact. The coefficient of friction is highly dependent on the roughness of these surfaces. One of the many ways the coefficient can be lowered or lowered is to lubricate the surface or make it shiny by removing the peaks that caused the roughness.
