Explanation:
Esterification occurs when a carboxylic acid reacts with an alcohol. This reaction can only occur in the presence of an acid catalyst and heat. It takes a lot of energy to remove the -OH from the carboxylic acid, so a catalyst and heat are needed to produce the necessary energy.
Answer:
B.) a cation that is smaller than the original atom
Explanation:
When the atoms of an element gains or loses electrons, it becomes charged. This charged atom is called an ION. An ion can either be a CATION or ANION depending on whether the atom loses electrons to become positively charged (cation) or gains electrons to become negatively charged (anion).
In this case, magnesium (Mg) atom gives up or loses electron(s) to become an ion, it will become positively charged and hence called a CATION. However, since it loses electrons in its atom, it becomes SMALLER than the original magnesium atom. This is because the electrons left in the atom becomes more attracted to the nucleus and decreases the ionic radius.
Yeah so you have to start of with converting your first two values into moles (forget the third one)
97.5 g NO * 1 mol/30.01 g NO = 3.25 moles NO
88.0 g O2 * 1 mol/16.00 g O2 = 5.5 moles O2
now we can find the limiting reactant by checking for the amount of product each reactant should give us by using molar ratios
3.25 mol NO * 2 mol NO2/2 mol NO = 3.25 mol NO2
5.5 mol O2 * 2 mol NO2/ 1 mol O2 = 11
so NO is the limiting reactant since it produces less product/gets used up quicker
3.25 mol NO * 2 mol NO2/2molNO = 3.25 mol NO2
so this is our theoretical yield and the question provides us with the actual yield (2.68 moles). since the actual yield is given in moles, we don't have to convert to grams. our percent yield formula goes like: actual yield/theoretical yield * 100
2.68 mol/3.25 mol * 100 = 82.46%
The ratio which denotes the relation between the two different units is said to conversion factors.
According to conversion factors, the relation between calorie and kilojoule is given as, one Calorie is equal to 4.184 kJ.
1 Cal = 4.184 kJ
Now, according to above relation, convert 300 calories into kilojoules.
300 calories =
= 
Thus, kilojoules present in soda is equal to 
This is likely the phase change from solid to gas, or sublimation. Gas molecules have more random motion and higher kinetic energies than liquid molecules, so the change is sublimation.
