Explanation:
The following data has been provided:
Energy of radiation absorbed by the electron in the hydrogen atom = 
As energy is absorbed in the form of a photon, the frequency is calculated accordingly:
E = 
= 
= 
or, = 
It is known that 
= 
According to the De-Broglie equation 
with p = 
So, 
= 
Squaring both sides gives us:
= 
= 
where m = mass of the electron
Therefore,
=
=
J
Since K.E = 
= 
=
Our conclusion is that the kinetic energy gained by the electron in the hydrogen atom is 
.
The patient needs to receive 285.71 ml.
1000 ml contains 70 gr of glucose.
x contains 20 gr of glucose.
x=1000*20/70
Answer:
The integer value of x in the hydrate is 10.
Explanation:
Molar concentration of the solution = 0.0366 M
Volume of the solution = 5.00 L
Moles of hydrated sodium carbonate = n
Weight of hydrated sodium carbonate = n = 52.2 g
Molar mass of hydrated sodium carbonate = 106 g/mol + x * 18 g/mol
By solving for x, we arrive at:
x = 9.95, approximating to 10
The integer x in the hydrate equals 10.
Response:
of 
can be found in 39.5 grams of .
Clarification:
Atomic weights: P= 31, F= 19,
The molar mass equals 1 atomic weight of P + 5 atomic weights of
F= 31+5 × 19
= 31+95
=126 g/mole
The number of moles in 39.5 gm of
equals 
= 
=0.3134 moles
1 mole of any substance encompasses
0.3131 moles comprises 0.3134
Thus, of can be found in 39.5 grams of .
An r-selected species has a significantly faster reproductive rate compared to K-selected species.
The focus of r-selected species is on quick maturation and reproduction. They are likely to breed during short periods when water supply is available, thus enhancing their survival chances.
Conversely, K-selected species prioritize nurturing their young and tend to reproduce later. Due to the longer maturation time before breeding, by the time K-selected species are ready, the water supply may be depleted, leading to lower survival odds.
Hope this clarifies!
