In an electric kettle a current of 8 10A flows through the heating element. Explain in atomic terms how an electric current causes the element to heat up. If we need water for our body, why is water a waste product of glucose combustion when we respire, and ...
A compound is sometimes confused with amixture, but the two differ in important ways. In a mixture, substances are combined, but there's nochemical reactionor bonding like that found in compounds. The individual substances in a mixture retain their ownpropertiesand can be separated into their o...
You’ll want to mix these specific ingredients all together. Make sure that you combine it within an open wide mouth container or mixing bowl. This mixture will combine to create air pockets and bubble up profusely, so do not blend it, shake it, or store it in a closed jug or container...
How can the moon retain the element helium since it has no atmosphere? Why does -CN acts as the electrophile and the H20 acts as the nucleophile in the nucleophilic attack? Explain melting in the rock cycle When you mix Sodium Thiosulfate and Hydrochloric Acid, why does the solution...
recorded similar EAC values with a negatively charged zwitterionic viologen in only 1 h20, which rather thwart the hypothesis of an electrostatic impact. Finally, the relatively slow kinetics observed for the non or less porous lignin and humic acid powders (Supplementary Figs S15 and S16) also...
A mixture of alumina (Al20s) and clay (A2h02SiO22H20), and lithium in the form of a lithium compound is prepared in the form of bars and melted to a state of complete fusion as by introducing the bars into an electric arc. If cooled in the usual manner the crystals will be of ...
Is copper an element, a compound, or a mixture? Explain. What happens immediately after copper and silver nitrate are mixed? Describe what you would observe. Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper ni...
Data were expressed as a ratio to the solvent control cells (DMSO CTL or PBS CTL depending on the respective solvent of the compound; cells exposed to medium containing 0.5% v/v DMSO or PBS). The use of DMSO or PBS as a solvent was based on preceding in vitro testing [30]. 4.3. ...
Also supporting this scenario is the work of Pavel Flegontov and colleagues suggesting mid‑Holocene ad‑ mixture between Asian and American populations, which has contributed substantially to N‑D ancestry [12]. To help clarify this situation, the present study will survey several key lexical...
