They like cheese because it is easy to eat and it tases really good
Atoms which might substitute for one another can be found in the same column in the periodic table.
So, since Si and C are found in the same column, they can substitute each other.
1. Si = C
2. K = Na
3. Nb = V
4. Cu = Ag
5. P = As
6. Mg = Ca
Answer:
n = 30.36 mol
Explanation:
Given data:
Temperature of gas = 120.0°C
Pressure of gas = 26.1 bar
Volume of gas = 38.0 L
Number of moles of Cl gas = ?
Solution:
Formula:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.08314 bar.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
120+273 = 393 K
26.1 bar ×38.0 L = n × 0.08314 bar.L/ mol.K × 393 K
991.8 bar.L = n × 32.67bar.L/ mol
n = 991.8 bar.L/ 32.67bar.L/ mol
n = 30.36 mol
Answer:
answer is 77.45grams you use stoichimetric formula by comparing CaCl2 and Agcl
We can't use the nitrogen present in the atmosphere although 80% of the atmosphere consists of nitrogen only.We get this from the plants called as leguminous plants which can convert or fix atmospheric nitrogen into usable ones..
