Answer:
Decreasing the diameter of the channel by removing aa's. Since Na+ is chemically similar to K+, one can assume the difference must be due to the size of the atom. The K+ ion is larger than the Na+ ion, so reducing the diameter of the channel can allow Na+ to enter while preventing K+ entry. This explains clearly and perfectly how reducing the diameter reduces the
transport of K+ in favor of Na+ transport.
Answer:
The new temperature is 1596 C.
Explanation:
Charles's Law indicates that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases.
Statistically, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio that exists between the volume and the temperature will always have the same value:

Being an initial state 1 and a final state 2, it is fulfilled:

In this case:
- V1= 25 L
- T1= 350 C= 623 K (being 0 C= 273 K)
- V2= 75 L
- T2= ?
Replacing:

Solving:


T2= 1869 K= 1596 C
<u><em>The new temperature is 1596 C.</em></u>
The name of that compound would be ammonium phosphate.
Answer:
The mass of ascorbic acid in 2.87×10−4 mol are 50,5 mg
Explanation:
Molar mass = 176 g/mol
Moles . molar mass = grams.
2,87 x10*-4 m . 176 g/m = 50,5 x10*-3 grams
A human can take one sweet lime and half to cover the daily requirement of vitamin C. =)
