The sodium-potassium pump of cell function is to take 2 potassium atoms into cells and dump the 3 sodium outside cells. The pump is also needed ATP as energy to make it work. That is why the pump sometimes referred as Na3/K2 ATPase pump.
The pump cannot do these things separately. That means if there are much potassium outside cells but there is no sodium, the pump will catch and keep the potassium then wait until they find sodium inside cells. If there is no sodium inside cells, the pump will not work even if there is much potassium outside.
Answer:
The value is
Explanation:
From the question we are told that
The molar mass of is
The total mass is
The uncertainty of the total mass is
Generally the molar weight of calcium is
The percentage of calcium in calcite is mathematically represented as
Generally the mass of each sample is mathematically represented as
Generally mass of calcium present in a single sample is mathematically represented as
The uncertainty of mass of a single sample is mathematically represented as
The uncertainty of mass of calcium in a single sample is mathematically represent
Generally the average mass of calcium in each sample is
Answer:
it is true because there is west,south and etc
Answer:
Both are different.
Explanation:
Both rocks are different from one another because both formed from different types of rocks. Rock A was formed from small pieces of rock while on the other hand, Rock B was formed from liquid rock so they both have different sources of rocks from which they were formed. Forming at the same time does not show that they are similar to each other, it is their source which decides that they are similar or different.
You may find in the attached picture the structure for compound (A) and (B).
Explanation:
The compound (A) and (B), which are haloalkanes, will undergo base-promoted E2 elimination and it will form the alkene (C) with the double bond in the second position. Zaitev's rule, which is an empirical rule, tell us that the halogen will leave with the hydrogen from the neighbor carbon which have the lowest amount of hydrogen, in the picture this specific hydrogen have a blue color.
Further compound (C) it will form compound (A), as a major product, by addition of hydrobromic acid. The Markovnikov's rule, which is also empirical, tell us that the halogen from the acid will add the carbon, involved in the double bond, that have the lowest amount of hydrogen.
Compound (C) will participate to a hydrogenation reaction to form 2,6-dimethylheptane.
