It's Hemoglobin- i just took test
the answer is A. temperature
Kelvin is the standard measurement unit for temperature
the temperature at which the gas molecules exert the smallest pressure is the absolute zero in the Kelvin scale. At absolute zero the gas molecules have minimal motion.
Pressure is directly proportional to temperature of the kelvin scale.
0 K is equivalent to - 273.15 °C
Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
Answer:
Neucler fission is a radioactive decay process. The nucleus of an atom splits into two.
Answer:
.
.
Explanation:
Hello,
In this case, since the ionization of methylamine is:
The equilibrium expression is:
And in terms of the reaction extent which is equal to the concentration of OH⁻ as well as that of CH₃NH₃⁺ via ice procedure we can write:
Whose solution for via quadratic equation is 9.24x10⁻³ M since the other solution is negative so it is avoided. Therefore, the concentration of OH⁻ is:
With which we can compute the pOH at first:
Then, since pH and pOH are related via:
The pH turns out:
Best regards.
