Answer:
It's explained below.
Explanation:
An everyday situation is when we raise an object.
Now, when we raise an object, energy is transferred to the Earth object system and thus the gravitational field energy of the system will increase.
Now, this energy is usually released when the object falls. The mechanism of this release is known as gravitational force.
In the same manner, two magnetic and electrically charged objects that are interacting at a distance will exert forces on each other and this can lead to transfer of energy between the interacting objects.
Two hydrogen and two oxygen multiply for two
Answer:
4) 1.5 mol
Explanation:
Well, the equation is already balanced and the mole to mole ratio of reactants and products are all 1. So if the limiting reactant is HCl and you have 1.5 mol, you do the mole to mole ratio with NaCl and since it is 1 to 1, there'd be 1.5 mol of NaCl.
A binary compound of oxygen with another element is called oxide. An oxide is a binary compound of oxygen and another element. Oxygen combines with metals and non-metals to form respective oxides.
The answers here is B) Before, the substance was a gas, later it was a liquid.
Gas particles move freely and away from each other. However, liquid particles move around each other.
