Answer : The correct option is, (a) 345 K
Explanation :
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree Celsius is, 72
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in Kelvin is, 345 K
so, There are (1/12.0)moles with each mole having 6.022 x10^23 atoms. 1 mole of carbon-12 has 6.02 x 1023 iotas.
H3O4 is your answer but u should use your chart
Answer:
No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.
From the given chemical equation we see that 43 kcal of
energy is needed for every 2 moles of NO. First let us calculate the moles of
NO with a molar mass of 30 g/mol.
moles NO = 112 g / (30 g/mol) = 3.73 mol
So the total heat absorbed is:
heat = (43 kcal / 2 mol) * 3.73 mol
<span>heat = 80.195 kcal</span>
