How many shared electrons are in a single bond?

How many shared electrons are in a single bond? two electrons Why potassium sulfide has a high melting point? It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. The greater the charge on the ions, the stronger […]

What materials are poor insulators?

What materials are poor insulators? Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood. Why does aluminum heat up faster than steel? Aluminum has much more […]

What is controlled variable example?

What is controlled variable example? Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment. What are […]

What is the impact of carrying capacity on ecosystems?

What is the impact of carrying capacity on ecosystems? Carrying capacity is the largest population size that an ecosystem can sustainably support without degrading the ecosystem. To a certain extent, population numbers are self-regulating because deaths increase when a population exceeds its carrying capacity. Why is carrying capacity important in ecosystems? When an ideal population […]

Is Steam matter Yes or no?

Is Steam matter Yes or no? Water illustrates the three states of matter: solid (ice), gas (steam), and liquid (water). Why is steam so powerful?

What is the pOH if the pH is 3?

What is the pOH if the pH is 3? This means that if you know either pH or pOH, you know the other! So, if the pH of your acidic solution is three, you can plug this in the equation above to find the pOH: Thus, For a 0.001 M solution of HCl, the pH […]
