Answer: Free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
Explanation:
It is known that free energy change is represented by the symbol . Free-energy helps in determining the direction of a chemical reaction like if it is taking place in forward or backward reaction.
For a spontaneous reaction, the standard free-energy change is negative in nature and the reaction will proceed in forward direction.
Thus, we can conclude that free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
In impure substance that is reactive
Answer:
Explanation:
Hello,
In this case, the formula we use to compute the heat Q by increasing the temperature, in terms of the mass and the heat capacity is:
Titanium's heat capacity is 0.544284 J/g°C, thus, the for such temperature increase, the heat results positive as shown below:
Best regards.
Clouds help us predict severe storms by their appearance. Their are clouds that signify that a thunderstorm, for example, is going to occur. Look for small patches of alto-cumulus clouds, which signify thunderstorms.
The correct answer is option B.
Research focused on how to cure cancer is an example of applied research.
The examples of basic research are :
A.) Research focused on how the human brain works
C.) Research focused on detecting life on other planets
D.) Research focused on human behavior
Applied research targets to solve specific human problems that have commercial value in the present day. Basic research is about understanding the fundamentals of science and nature, and it is essential to laying down the foundation of applied research.
