O gás carbônico atmosférico reage com a água do mar conforme detalhado em (I): (I) CO2 + H2O ↔ H2CO3 ↔ HCO3-
As condições ambientais causadas pelo aumento de gás carbônico na atmosfera influenciam em processos caracterizados pela reação (II) durante o desenvolvimento de diversos organismos marinhos:

Tendo por base essas afirmações, assinale a alternativa correta;
Note e adote:
Considere o bicarbonato solúvel e o carbonato de cálcio insolúvel.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
