Chlorine has a smaller atomic size.
Explanation: As you move towards right of the periodic table, the atomic size decreases. This is because the number of protons is increasing towards the right of the periodic table, which applies a greater inward force on the electrons. that is why the elements on the right of the periodic table have a smaller atomic size when compared to the elements on the left. Since chlorine is on the right side of aluminium, it has a smaller atomic size.
Answer:
Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind.Barometers, manometers and anemometers are all scientific instruments. Scientists use barometers and manometers to measure atmospheric pressure, while anemometers measure wind speed.
Explanation:
Answer:
Molarity of 40 ml of NaoH is 0.3125 mL
Explanation:
As we know
Molarity of acid * volume of acid = molarity of base * volume of base
Substituting the given values, we get

Molarity of 40 ml of NaoH is 0.3125 mL
The eruption of a volcano lowers the temperature in the environment. The first time this observation was made, it was noticed that winter came aryl that year and the first snow that fell did not immediately melt on the ground. The ash and smoke from the eruption of volcanoes creates a cloud and shroud which dims the effect of the sun and the land gets less exposure to strong sunlight. This in turn results in the lowering of temperature.
