Perhaps the most important attitude is curiosity. Curiosity a state of active interest or genuinely wanting to know more about something allows you to embrace unfamiliar circumstances, giving you a greater opportunity to experience discovery and joy. Indeed, studies show that life is better when you're curious.
Answer:
Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than a hydronium ion, so its pKa must be lower than that of a hydronium ion. Therefore, strong acids have a pKa of <-174. Strong acids can be organic or inorganic.
Explanation:
Bond Strength
Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak. Strong acids easily break apart into ions. Weak acids exist mostly as molecules with only a few ions in solution, therefore the bonds holding H and A together must be strong.

Hence, 5.1 * 10^-11 alpha particles is being emitted each second by the sample.
<h3>What is half life?</h3>
The term half life is the time taken for only half of the original amount of radioactive nuclides to remain.
Thus, we have that the half life is 432.2 years or 1.36 * 10^10 s.
k = 0.693/ 1.36 * 10^10 s
k = 5.1 * 10^-11 alpha particles per second.

Answer:
10 moles of methane
Explanation:
1 mole of methane contains 6.02 × 10^23 molecules (Avogadro's number)
x moles should contain 7.02 x 1024 molecules of
methane
So,
x= 7.02 x 1024 × 1/6.02 × 10^23
x= 10 moles of methane
