Chemical reactions happen by them self like if you hear baking soda and it makes a gas.
If the value of H is positive, it means you have to add that much heat to complete the reaction. If H is negative, it means that much heat is released during the chemical process. Because it is -73 kJ, 73 kJ of heat are released in the reaction.
Answer:
Explanation:
Empirical formula of ionic compound formed by two ions and is (for ) of AB (for x = y)
The above empirical formula is in accordance with charge neutrality principle
Here each cation ( and ) can form two ionic compounds by combining with two given anions ( and ).
So the four ionic compounds are:
Some organisms that could not survive where cats, dogs, birds, horses, fish, cows, every animal that was in hurricane Katrina was affected by it. Some of these animals were able to survive and others were rescued from near death.
Most of the animals could not adapt to this change because they are not used to this type of change.
