Solutions with pH less than 7 are acidic in nature.
Therefore, a substance of pH 6 will be a weak acid.
1.5 ms⁻²
Explanation:
We understand that Force is also given as mass * acceleration;
F = Ma
If force is 6N and the mass is 4kg of the object, the a can be evaluated as follows;
6 = 4a
6/4 = a
1.5 = a
= 1.5m/s²
Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.
My answer is....A
sorry if im wrong
Answer:
A. releases a large amount of heat
Explanation:
A reaction is said to be spontaneous if it can proceed on its own without the addition of external energy. A spontaneous reaction is not determined by the length of time, because some spontaneous reactions are completed after a long period of time. They are exothermic in nature. An example is the conversion of graphite to carbon which takes a long period of time to complete. Spontaneous reactions are known to increase entropy in a system. Entropy is the rate of disorder in a system.
In the combustion of fire, energy is released to the surroundings as there is a decrease in energy. This is an example of a spontaneous reaction because it is an exothermic reaction, which causes an increase in entropy and a decrease in energy.
