False
only observing chemical property will change its identity
Answer:
Explanation:
Hello!
In this case, for the reaction:
In such a way, via the rate proportions, that is written considering the stoichiometric coefficients, we obtain:
Whereas the reactants, CO and H2 have negative stoichiometric coefficients; therefore the rate of disappearance of hydrogen gas is related to the rate of appearance of methanol as shown below:
Which means that the rate of disappearance of hydrogen gas is negative and the rate of appearance of methanol is positive.

Yes, Titan is bigger than Mercury. So basically, it's true.
Answer:
Radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero. In other words the heat of the energy it radiates in infrared spectrum.
Answer:
The unknown element is Carbon.
(a) X is Carbon, its oxide is of acidic nature
(b) C+ O2 → CO2
Explanation:
We are given an unknown element that reacts with oxygen.
X + O2 → XO2
It is given that the oxide XO2 turns blue litmus red which is shown by acids, so XO2 is an acidic oxide. Also X will be a Non metal because Non metallic oxide is Acidic in nature.
The Oxide XO2 is dissolving is water. The oxide upon reacting with water will give an Acid.
XO2 type of oxide is found in the 14th group of the periodic table generally
So we have options like C, Si and Ge as these only have the Acidic oxide.
But when it comes to reactivity with water Only Carbon satisfies the need so the unknown element X is C.
CO2 + H2O → H2CO3 which is an acid.
(a) Element X is Carbon (C), The nature of the compound formed is Acidic.
(b) The reaction given will be as follows
C+ O2 → CO2
Therefore the unknown element is Carbon.
