What is buffer solution give example? Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added (Figure 1). A solution of acetic acid and sodium acetate (CH3COOH + CH3COONa) is an example of a buffer that consists of a weak acid and its salt. What […]
What periodic trend is most important for determining metal reactivity?
What periodic trend is most important for determining metal reactivity? Metallic and Non-metallic Character Within a compound, metal atoms have relatively low attraction for electrons, as indicated by their low electronegativities. By following the trend summary in the figure below, you can see that the most reactive metals would reside in the lower left portion […]
What is easier rolling or sliding?
What is easier rolling or sliding? When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction. It is always easier to roll than to slide an object over another object.So rolling friction is much less than the sliding friction. Why is sliding faster than rolling? 25ex2 […]

Why is the crater important?
Why is the crater important? The Planetary Deep Past Impact craters allow scientists to study a planet’s geological history—even when the records are buried beneath the surface. Rocks ejected by impacts contain minerals that formed in the presence of liquid water; some craters also show signs of ancient lakes. What is the biggest crater on […]
What are the four main blood vessels?
What are the four main blood vessels? The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the […]
Are fault lines dangerous?
Are fault lines dangerous? Major active faults such as the Hayward Fault are associated with many hazards. The most obvious hazard is that of large earthquakes, which induce ground shaking over a large area that can cause heavy objects to fall and windows to shatter, and can cause structural damage to buildings and bridges. How […]
What are the 4 biological rhythms?
What are the 4 biological rhythms? There are four biological rhythms: circadian rhythms: the 24-hour cycle that includes physiological and behavioral rhythms like sleeping. diurnal rhythms: the circadian rhythm synced with day and night. ultradian rhythms: biological rhythms with a shorter period and higher frequency than circadian rhythms. What happens if your circadian rhythm is […]
