because of the metling point of metals, it is difficult to just simply put metal together and have them to stay together without any type of glue or epoxy based creams.
wielding is used to melt the surface or even change the compound completely so they are able to combine with other metals.
same thing with atoms, you need a lot of heat, and speed to simply make salt or even copper because of the elements not really being favorable of each other.
Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
Explanation:
Let us assume that the value of =
Also at 1500 K, =
Relation between and is as follows.
Putting the given values into the above formula as follows.
Also,
or,
=
=
Thus, we can conclude that the value of is .
Here is the correct option: According to Newton's third law of motion, the balloon is pushed forward as the air is forced out. Newton's third law of motion states that for every action there is an equal and opposite reaction. This means that in every interaction, there is a pair of force that is acting on the interacting objects, the size of the force on the first object is equal to the size of the force on the second object.
What I found on google made it seem like the third one would be the correct answe
