The equation is :
moles=mass/molar mass
so, the mass is 203 and molar mass is 159.69
You divide the 203 by 156.69 as the equation shows
so the moles is 1.27 mol.
Answer:Hola UwU
Most chemical reactions involve the breaking and formation of chemical bonds. It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic.
Explanation:Adios~ UnU haha
The answer is D=Making new fossil fuels, hope this helps:)
<h2>Let us predict the gas and liquid products in option </h2>
Explanation:
option 1 : 2 upper H g upper O (s) right arrow 2 upper H g (l) plus upper O subscript 2 (g).
Chemical reaction
It is the reactants react to form products .
Chemical equation
It is the method of representing reaction in terms of moles , specifying states , symbols , molecular formulas etc .
This actually gives the complete info about the reaction .
In the above asked question or any other question we can specify the states by writting :
Solid as "S".
Liquid as "L"
Gas as (g).
Answer:
Morphology and phylogenetics revealed by fossils. Perhaps the strongest evidence to support the Cambrian evolutionary explosion of animal forms is the first clear appearance, in the Early Cambrian, of skeletal fossils representing members of many marine bilaterian animal phyla
