In what way are the chemical equations useful to us?
In what way are the chemical equations useful to us? ↵Chemical equation gives us the complete information about the reaction taking place. It tells the number of atoms of each element participating in the reaction. It tells the neccerssary requirements such as temprature, catalyst, etc. It also tells us the state of the elements in […]

What describes the movement of wind?
What describes the movement of wind? Movement of air caused by temperature or pressure differences is wind. Consequently, air blows anticlockwise around a low pressure centre (depression) and clockwise around a high pressure centre (anticyclone) in the northern hemisphere (see Figure 3.1). Which set of conditions describes a low pressure system? Explanation: A low pressure […]
