Been awhile since I done these but i believe it looks like this
Answer: it has full valence shells
Explanation: Hope this is it
Explanation:
The law of conservation of mass and energy according to thermodynamics is NOT violated. The ash of the wood weighs less than the initial wood because during the burning some of the mass was converted to gases that escaped into the atmosphere. Some of the carbon in the wood, for example, turned to carbon dioxide. Water in the wood also turned to gas (water vapour) and escaped.
If it is possible to capture all these gases and weigh them, then ideally it would be observable that the law of conservation is NOT violated.
Answer:
The weight of the objects has a name and is "Specific weight", this is measured in several measurements but the best known is the kg.
If we relate the density of the object with the weight we will obtain a deduction of the shape of the object.
Explanation:
The object can be more or less heavy according to its density and its chemical composition.The weight is nothing more than the attraction of that object with the interior of the earth, that is why in order to know well how heavy it is, it is necessary relate the density of the object, the material that composes it, the speed of gravity (10m / s2).
This refers to the fact that a kilo of feather is not the same as a kilo of lead, each object obtains its shape according to the more weight it has and the more attraction it can make to the center of the earth.
