Molar mass N₂ = 28.0 g/mol
1 mole ------------- 28.0 g
5 moles ------------ ?
mass = 5 . 28.0 / 1
mass = 140 g
hope this helps!
Explanation:
oh shi sorry I wish I could help but I'm stupid
Ans: grinding one of the reactants into a powder.
this increases the surface area and hence there would be more chances of collisions happening. therefore reaction rate would increase
Answer:
C. It makes sure there is a balance inside the body

They should identify the confounding variable.
Some condition that is not examined by the scientist might alter the experiment result. That condition is called confounding variable. If the method of the experiment same but result is very different, there should be unidentified confounding variable. It could be air humidity, temperature, ventilation, light, time of the year or anything that might not be seen by naked eye.
Try to redo the experiment with controlling variable as much as possible.
