Answer: O potássio possui apenas um elétron de valência. ... Considerando que o cálcio possui dois elétrons de valência, requer mais energia para a remoção de um elétron de valência. Devido a esse potássio, é mais reativo que o cálcio.
Explanation:
Environmental selective pressures. In other words, natural selection took place. It was the environment that caused these changes. Birds on the islands with the most suitable traits for survival thrived while the birds that didn't die.
Answer:
(A) stoichiometry
Explanation:
For example, Consider the reaction of the type ,
aA + bB-----> cC +dD
where b, a, d, and c are the stoichiometric coefficients for the balanced equation .
The equilibrium constant expression is denoted by K ,
equilibrium constant is the product's concentration each raised to the power of its corresponding stoichiometries , divided by reactant's concentration each raised to the power of its corresponding stoichiometries .
Answer:
Sodium ion and atom are both sodium-atoms, sodium ion is only the state of sodium-atom due to change in valence electrons, at this ion state time it is highly reactive, due to it’s reactivity they are unstable by there nature and try to search there partner element-atoms to make a stable ionized compound.
