The answer is C . Watery feel
When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is .
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,
Answer:
353kg
Explanation:
2000 x 0.1765 = 353kg
for every 1 cubic metre of helium there is 0.1765 kg of it
the balloon is holding 2,000 cubic metres of the helium.
That means that there are 2000 times of 0.1765kg of helium in the balloon
so you times 0.1765kg by 2000
The answer:
for the monoatomic <span>selenium ions
</span> -the ion charge of selenium is 2-, so the answer is [Se]2+
as for the monoatomic phosphorus ions
-the ion charge of phosphorus is 3-, so the answer is [P]3-
I think there are two choices that would be correct. The ideas by the Ancient Greeks that is least partially supported by scientific experiments are light is a stream of rays that comes with great velocity from the eyes of an observer and it is the result of rays that leave the eyes, reflect off an object, and interact with sunlight to become visible. It was the Greeks who laid out basic laws about reflection and refraction where they found that the angle of incidence is the same as the angle of reflection. They thought light rays came from the eye and that it travels towards the object which results to the objects as visible. This was called the concept of intromission.<span />
