Answer: true
Explanation:
All living things need food to provide materials for growth. ... A food chain typically only has a few steps (usually 4 at the most). This is because each time one organism eats another, some of that energy is used up and released as heat.
Those are basically molecular formula. Which is Table sugar or cane sugar. Generally called sucrose.
Answer is: 12 grams of the isotope carbon-12 (¹²C).
The Avogadro’s number is the number of atoms in 12 grams of the isotope carbon-12 (¹²C).
Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).
The Avogadro number has value 6.022·10²³ 1/mol in the International System of Units; Na = 6.022·10²³ 1/mol.
The balanced reaction between nitrogen and hydrogen to form ammoinia is as shown.
N2 + 3H2=2NH3
Dividing everything by 3
1/3N2 + H2 = 2/3NH3
All the hydrogen reacts with 1/3 of 0.5 atm of N2
The amount of product is 2/3 × 0.6 atm = 0.4 atm NH3
The unreacted nitrogen is 2/3 × 0.6 atm =0.4 atm Nitrogen
That adds up to 0.8 atm
Explanation:
the carolimeter help trap the heat from a chemical reaction taking place . from that point we can find the heat by taking a thermometer to measure heat in the water, then using that answer we can find out how much of the heat has been released into the atmosphere etc.
