Answer:
- Oxido de magnesio
Explanation:
Mg → magnesio
O → oxígeno
La unión del oxígeno (no metal) con un metal, forma el determinado óxido que se nombra como óxido de .... y el no metal.
En este caso, podemos deducir que el contenido del frasco es de óxido de magnesio, aunque viendo que hay un sólo átomo de oxígeno podemos llamarlo como monóxido de magnesio, similar al CO (monóxido de carbono).
A partir de que el magnesio sólido entre en contacto con el aire, se produce MgO de acuerdo a la siguiente reacción:
2Mg + O₂ → 2MgO
Explanation:
The reason as to why the dark chocolate always melted the fastest was because of it's colour. It was a darker shade than the milk and white chocolate and the sun naturally absorbs dark colours therefore it melted faster.

<h2>Answer:</h2>
The correct option is Pf = Pi
<h2>Explanation:</h2>
Momentum is the product of velocity and mass of an object. It is a physical quantity and the law of conservation of momentum says that for a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. So simply it means that Pf = Pi.
Answer:
Electromechanical waves are defined as the waves which resulting from the interaction of magnetic fields, and oscillating electric. Some examples of these electromechanical wave are infrared, microwave, ultraviolet, visible, etc.
When these waves are arranged in the order of increasing wavelength then it's called an electromagnetic spectrum, and
spectral regions in order of increasing wavelength, we will get is:
Ultraviolet<visible<infrared<microwave.
Answer:
342.3 g/mol for sugar, 58.44 g/mol of salt, and 84.007 g/mol for baking soda.
Explanation:
This is so because of the formula of molar mass: Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol.
Hope this helps :)
