Lighted match is brought near a candle wick in order to light the candle which of the 4 factors affecting reaction rate is most important concentration temperature surface area or catalyst?
Temperature is the most important factor affecting the reaction rate in this scenario. By increasing the temperature with the lighted match, the kinetic energy of the particles is increased, leading to more collisions and a faster reaction between the match and the candle wick.
Which os the following represents a chemical reaction?
A chemical reaction occurs when substances undergo a transformation to form new substances with different properties. This can involve the breaking and forming of chemical bonds, resulting in changes in energy and composition. Common indicators of a chemical reaction include color change, gas production, formation of a precipitate, or temperature change. To identify a specific example, look for a scenario where reactants interact to yield products that are chemically distinct from the original materials.
What is the plural of scenario?
The plural of scenario is scenarios.
What can cause a runaway reaction?
A runaway reaction can be caused by several factors, including excessive heat generation that surpasses the cooling capacity of the system, leading to an uncontrolled increase in temperature. Additionally, high concentrations of reactants or catalysts, as well as inadequate mixing, can contribute to a rapid and uncontrolled reaction rate. Environmental factors, such as changes in pressure or temperature, can also initiate a runaway scenario. Proper monitoring and control measures are essential to prevent such incidents in chemical processes.
Increasing the pressure of a gas over a solution increases the solubility of the gas in the solution This is an example corresponding to which law?
This scenario corresponds to Henry's law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Therefore, by increasing the pressure of the gas, you can increase the amount of gas that dissolves in the solution.
Present scenario of e-commerce in India?
in India it is increasing very rapidly and it help everybody in there day to day life.
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.

How can one determine the direction of acceleration in a given scenario?
To determine the direction of acceleration in a given scenario, you can look at the change in velocity of an object over time. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.

What are indicators of a chemical change when 2 substances are mixed together?
Some indicators include:Change in TemperatureChange in ColorNoticeable Odor (after reaction has begun)Formation of a PrecipitateFormation of BubblesWhen two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.
What is the dew-point temperature when the dry bulb temperature is 16 degrees Celsius and the wet bulb temperature is 11 degrees Celsius?
The dew-point temperature is the temperature at which air becomes saturated with moisture. Using a psychrometric chart or calculator, you can determine that the dew-point temperature is approximately 10 degrees Celsius in this scenario.
How can one effectively solve Gay-Lussac's Law in a practical scenario?
To effectively solve Gay-Lussac's Law in a practical scenario, you need to understand the relationship between pressure and temperature of a gas at constant volume. Use the formula P1/T1 P2/T2, where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature. Make sure to convert temperature to Kelvin and pressure to the appropriate units. Then, plug in the values and solve for the unknown variable.
What is a scenario causes gene flow?
A scenario that causes gene flow is when individuals from one population migrate to and interbreed with individuals from another population, exchanging genetic material. This movement of individuals can result in the transfer of genes between populations, increasing genetic diversity and potentially altering the genetic makeup of both populations.
