Chemical energy is stored within atoms
Answer: There are four atoms
Explanation: mass of Cl atom is 35.45 amu
Amount of atoms n = m/M = 142 / 35.45 = 4
Answer:
Explanation:
Hello,
In this case, by considering the given seminormal solution, we infer it is a 0.5-N solution which means that we can obtain the equivalent grams as shown below for the 55 cc (0.055 L) volume:
Next, since sodium carbonate has two sodium ions with a +1 oxidation state each, we can obtain the moles:
Finally, the mass is computed by using its molar mass (106 g/mol)
Regards.
Answer:
The atom will have a negative charge.
Explanation:
Electrons are subatomic particles with a negative charge, protons are subatomic particles with a negative charge, and neutrons have no charge. When a neutral atom's balance is disrupted by an extra electron, the atom becomes negatively charged.
An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
