What is the relationship between metallic and ionization energy? Metallic character refers to the level of reactivity of a metal. The metallic character increases as you go down a group. Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to […]

Why is argon the cheapest noble gas?
Which is brighter bulbs in series or parallel?
Which is brighter bulbs in series or parallel? Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit. Unscrewing one bulb has no effect on the other bulb. Which bulb will glow brighter in parallel? Key Points: In […]
Which state of matter has the greatest amount of molecular motion?
Which state of matter has the greatest amount of molecular motion? gas What has the greatest molecular motion? They are in constant motion and also different from molecules such as liquid molecules have more freedom of movement compared to solid molecules. At the same time they show less movement compared to gaseous molecules. In other […]
Does the buoyant force on a floating object depend on the weight?
Does the buoyant force on a floating object depend on the weight? The buoyant force depends on the mass of the object. The buoyant force depends on the weight of the object. The buoyant force is independent of the density of the liquid. The buoyant force depends on the volume of the liquid displaced. What […]
What happens to plate A as it collides with plate B?
What happens to plate A as it collides with plate B? Answer: The volcanic arc is formed to “plate A” as it collides with “plate B”. The collision of these two plates results in the oceanic current which is generated. The earthquake is produced because of the volcanic arc creation between the plate A and […]
What are two differences between a compound and mixture?
What are two differences between a compound and mixture? Mixtures are the impure substances, made up of two or more physically mixed substances and not in the fixed ratio. Compounds are the pure form, made up of two or more chemically mixed elements and in a fixed ratio. Mixtures do not have meting or boiling […]
Why is it important to have a reference point?
Why is it important to have a reference point? A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to. Is the cyclist accelerating How do you know? How do you know the cyclist is accelerating? a graph of […]
What is the meaning of uncertainty in decision making?
What is the meaning of uncertainty in decision making? A decision under uncertainty is when there are many unknowns and no possibility of knowing what could occur in the future to alter the outcome of a decision. A situation of uncertainty arises when there can be more than one possible consequences of selecting any course […]
