If you mix all of the primary colors, you get White light
The question is incomplete, the complete question is;
the element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. its melting point is 1910 degrees celsius.” which correctly evaluates the statement? not reliable because opinions are presented, reliable because testable facts are presented, not reliable because it is very brief ,reliable because metric units are used
Answer:
reliable because testable facts are presented
Explanation:
Science is a body of knowledge that deals with testable facts. Science is highly empirical and any superstitious proposition is quickly discarded as nonsense.
The statement, ''The element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. Its melting point is 1910 degrees Celsius" presents facts that can be verified by laboratory investigation.
Hence we can conclude that the given statement is reliable because it contains testable facts.
Answer:
no the answer is oxidation
Answer:
1.
, remain the same.
2.
,increase.
3.
, decrease.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
Increase the pressure
If the pressure of the container is increased, the volume will decrease according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place.
1. 
On increasing the pressure ,the equilibrium will shift in direction where decrease in pressure is taking place,so reaction will shift in no direction because number of gaseous moles are same on both sides. Hence no increase in number of moles of products.
2. 
On increasing the pressure ,the equilibrium will shift in direction where decrease in pressure is taking place,so reaction will shift in forward direction because number of gaseous moles are less on product sides. Hence ,increase in number of moles of products.
3. 
On increasing the pressure ,the equilibrium will shift in direction where decrease in pressure is taking place,so reaction will shift in backward direction because number of gaseous moles are less on reactant side both sides. Hence, decrease in number of moles of products.
