Answer:
The solution will be dilute
Explanation:
The concentration of a solution is defined as the ratio between an amount of solute (Glucose, in this case) and an amount of solvent (Water in this case).
As the student is adding some water (Solvent), the amount of solute per amount of solvent will decrease. That is, if the concentration decreases,
the solution will be dilute

Answer:
Ar < Cl - < S2-
Explanation:
All the species written above are isoelectronic. This means that they all possess the same number of electrons. All the species above possess 18 electrons, the noble gas electron configuration.
However, for isoelectronic species, the greater the atomic number of the specie, the smaller it is. This is because, greater atomic number implies that their are more protons in the nucleus exerting a greater attractive force on the electrons thereby making the specie smaller in size due to high electrostatic attraction.
Answer:
A very high powered nuke.
Explanation:
The sheer force,as used in "Armageddon",will have to be more powerful than Tsar Bomba,the largest nuclear bomb to detonate in history.In order to make this bomb,you would need a <u>lot</u> of nuclear fission.This is a delicate process,so we must do it carefully,but not too slowly.Next:The detonation.It would either have to be rocket powered to the asteroid cluster,asteroid,etc,or it would have to be transported.Once near the target,it would have to be remote detonated from a far distance,because radiation travels FAST through space,therefore,if not a far enough distance away,you would melt into nothing,probably.Once detonated,there are multiple possibilities,the rock could split in half and go separate ways around the earth,reattach,and keep going.Or maybe the bomb would do nothing and just put another crater in the asteroid,and we all die.There are way more,but to the point,a nuclear bomb has a 50% chance of working,but its the best way.
Answer:
4NH₃ + 5O₂ → 4NO + 6H₂O ΔH = -904 kj
Explanation:
Given data:
Energy evolved when one mole of NH₃ react = 226 kj
Energy evolved when 4 mole of NH₃ react = ?
Solution:
Chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
It is stated in question that when one mole of ammonia react 226 kj energy evolved.
When 4 moles react energy evolved is,
1 mol = -226 kj
4 mol × -226 kj / 1mol
-904 kj
when 4 moles of ammonia react 904 kj energy is evolved.
Complete thermal equation:
4NH₃ + 5O₂ → 4NO + 6H₂O ΔH = -904 kj
