Atoms react because they wish to become a Noble Gas, and they do this by sharing, gaining, or losing electrons to become stable. The correct answer therefore is, "do so to share, gain, or lose electrons to become stable". Not all atoms have a full octet of electrons in their valence shell, this is dependent based on what type and how it's obtained. They can't be separated again through "physical" means and the claim "all atoms lose electrons" is invalid.
The total pressure is the sum of all the partial pressures of the different components in the system. In this case, if the total pressure is 520 torr, and the partial pressure of nitrogen is 266 torr, and the only components are nitrogen and sulfur dioxide, this means that the rest of the pressure is all due to sulfur dioxide.
So the partial pressure of sulfur dioxide = 520 - 266 = 254 torr SO2.
0.1 M x 0.5L = 0.05 mols HCl.
Adding 25 mL 2M NaOH is
2M x 0.025 L = 0.05 mols NaOH.
What you want to do is to back off very slightly with the NaOH (you might try something like 24.95 mL which I calculate to give 0.00019 M or a pH of 3.7. Inching closer, 24.99 mL would leave H^+ of 4E-5 for pH 4.4. The problem here is two-fold.
hope it helps
Answer:
Explanation:
B)The compound potassium chloride (KCl) has different properties than potassium (K) and chlorine (Cl).
I think the correct answer from the choices listed above is option A. The statement that states a negative impact of chemistry on the society is that hazardous <span>coolants in refrigeration units were replaced. One example of this coolant is the </span><span>production and use of chlorofluorocarbons (CFCs) which replaced by more safer coolants.</span>
