Answer:
B
Explanation:
alkene is no polar compounds
and insoluble in water
Answer:
B. A rate constant
Explanation:
The mathematical expression of rate law is given below,
Rate = K[A]m[B]n
This rate law show the relationship between the rate of chemical reaction and concentration of reactants.
In given equation [A] and [B] are molar concentration of reactants while K represent rate constant.
The value of K is specific for particular reaction at particular temperature,
m and n are represent exponents and determine experimentally. The value of K is not depend upon the concentrations of reactant but depend upon the surface area and temperature
The recipe for an omelet are:
<u>Ingredients</u>
- 1 Egg
- Salt and pepper ( 1 tablespoon )
- Butter ( 1 tablespoon )
<u>Recipe:</u>
- Turn on the heat and place a pan on it.
- Add butter to the pan.
- Crack the egg and whisk it properly.
- Add the whisked omelet onto the pan and stir.
- Add salt and pepper.
<h3>How to illustrate the information?</h3>
When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.
When we add butter to the pan, then the temperature of the pan was more than that of the butter.
Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.
When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.
These are the chemical reactions depicted.

Answer:
No, compound A and B are not the same compound
Explanation:
According to the law of definite proportion "every chemical compound contains fixed and constant proportions (by mass) of its constituent elements." (Encyclopedia Britannica)
We can see in the question that the ratio of flourine to sulphur in compound A is 1.18 while the ratio of flourine to sulphur in compound B is 2.37.
The two chemical compounds do not contain a fixed proportion by mass of their constituent elements therefore, they can not be same compound according to the law of definite proportions.
Answer:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Explanation:
Anode:
3Mg(s) ----------> 3Mg2+(aq) + 6e
Cathode:
2Al3+(aq) +6e ---------> 2Al(s)
Magnesium is more electro positive than aluminum hence it functions as the anode. Six electrons are lost/gained in the redox process as shown in the oxidation and reduction half reaction equations above. Magnesium is oxidized to magnesium ion while aluminum is reduced to elemental aluminum.
