Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.
Good luck ;)
Answer:
DD or Dd
Explanation:
Having dimples is the dominant trait which means if he is heterozygous, the dominant trait will still show. So it can be homozygous dominant or heterozygous.
This task can be easily done once we have the periodic table. From the periodic table, it can be seen that potassium is in the fourth row. Thus, it has four energy levels. If we are to use the same principle as that stated above, the number of energy levels for each are as follow:
Calcium = Ca (in periodic table) = energy levels
Iron = Fe (in periodic table) ; 4 energy levels
Nickel = Ni (in periodic table); 4 energy levels
Zinc = Zn (in periodic table) = 4 energy levels
Answer:
hand sope
Explanation:
because they are made up of carboxylic acid and sodium hydroxide (NaOH) Thus the salts formed by the reaction between a strong base and a weak acid are basic in nature.
Answer:
00167M.
Explanation:
1 ml of 1.00HCl contains 1/1000 moles HCl.
this is 0.001 mole
whenput in 60 ml of water, the concentration is
(1/1000)/(60/1000)
mutiply by 1000/1000
the answer is 1/60 = 00167M.
