What is the charge on proton? Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom. What is the potential energy of a proton at the midpoint of the capacitor? The potential […]
How are 15 electrons arranged in a phosphorus atom?
How are 15 electrons arranged in a phosphorus atom? When we write the configuration we’ll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 […]
What does the space above Mercury create?
What does the space above Mercury create? The vacuum formed when a long tube, closed at one end and filled with mercury, is inverted into a mercury reservoir so that the open end of the tube is below the surface of the mercury. The pressure inside the Torricellian vacuum is the vapour pressure of mercury, […]
When solid melts its temperature remains the same?
When solid melts its temperature remains the same? When solid melts, the temperature remains the same, this is because the absorbed heat is utilized in breaking the forces of attraction between the particles and hence solid changes to a liquid state without changing in temperature. Why does ICE take so long to melt? Assuming the […]

Do batteries last longer in parallel or series?
Do batteries last longer in parallel or series? When batteries are hooked up In series, the voltage is increased. For example, two – 6 Volt batteries connected in series produce 12 Volts. When batteries are hooked up in parallel, the voltage remains the same, but the power (or available current) is increased. This means that […]
What is the most stable ion of chromium?
What is the most stable ion of chromium? Oxidation States of Chromium Chromium exhibits a wide range of possible oxidation states, where the +3 state is the most stable energetically. The +3 and +6 states are the most commonly observed in chromium compounds, whereas the +1, +4 and +5 states are rare. Why chromium +3 […]

Can bone marrow repair itself?
Can bone marrow repair itself? It can replace diseased, nonfunctioning bone marrow with healthy functioning bone marrow. This is used for conditions such as leukemia, aplastic anemia, and sickle cell anemia. It can regenerate a new immune system that will fight existing or residual leukemia or other cancers not killed by chemotherapy or radiation. How […]
How do you convert linear momentum to angular momentum?
How do you convert linear momentum to angular momentum? For objects with a rotational component, there exists angular momentum. Angular momentum is defined, mathematically, as L=Iω, or L=rxp. This equation is an analog to the definition of linear momentum as p=mv. Units for linear momentum are kg⋅m/s while units for angular momentum are kg⋅m2/s. What […]
