Answer:
The answer to your question is:
Explanation:
Data
moles H=?
moles of N = 0.0969
moles of NH₃=?
N₂ (g) + 3 H₂ (g) ⇒ 2NH₃ (g)
Process
1.- Set a rule of three to calculate the moles of hydrogen
1 mol of nitrogen ------------- 3 moles of hydrogen
0.0969 moles of N ---------- x
x = (0.0969 x 3) / 1
x = 0.2907 moles of hydrogen
2.- Set a rule of three to calculate the moles of ammonia
1 mol of nitrogen -------------- 2 moles of ammonia
0.0969 mol of N -------------- x
x = (0.0969 x 2) / 1
x = 0.1938 moles of ammonia
Therefore carbohydrates are covalent compounds. Since electrons or more specifically valence electrons from their respective atoms are shared to form chemical bonds and acquire greater chemical stability from the bonds, this is present through out this biological macromolecule and is thus covalent.
Hi the answer your looking for is C, muscle: bone to bone connection.
Hope this helps you.
Is equal to 0 k .This is because an absolute zero temperature is the temperature in which nothing can be cooled. The standard measurment for temperature is celcius which is already 0 but when we are converting 0 K to celcius we will gwt 273 celcius which is definitely not an absolute zero
Because the reactants react with each other and chemically react to produce a different product like with fire when it reacts with the wood it burns and the product left behind is a new different substance from the reactants in this case the product is ash
