1: China is agreeably a third world country because they do not know what they should eat, they think that beating an animal and causing it pain and suffering makes the meat taste better which is very, very unjust and cruel. This disease was started where a Bio-Disease plant was, and considering coronavirus is spreading so fast and killing so many people, ( not unlike the swine flu that ALSO originated in China ) This indicates it is very possible that this disease could have been engineered. ( not unlike the swine flu either )
2: The person itself is smart, people are stupid, fearmongering, and have been weakened through the years. The moment the media said there was a pandemic, everyone ran to the nearest convenience store to buy toilet paper, then they locked themselves in their houses because people said to do so, they bought surgical masks ( that only help you if you have secondary breathing problems, because you go to take them off and touch your face ) that they HEARD will help them. MY opinion is do what makes YOU feel comfortable, you can't help other people, but you can help yourself.
3: I don't exactly understand this question, so if you could rewrite this part I could give you an answer.
Hope this helps, if not, comment below please!!!
Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.
Answer:
1.79 mol.
Explanation:
- For the balanced reaction:
<em>2NaCl + F₂ → 2NaF + Cl₂.
</em>
It is clear that 2 mol of NaCl react with 1 mol of F₂ to produce 2 mol of NaF and 1 mol of Cl₂.
- Firstly, we can get the no. of moles of F₂ gas using the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm (P = 1.2 atm).
V is the volume of the gas in L (V = 18.3 L).
n is the no. of moles of the gas in mol (n = ??? mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (299 K).
∴ no. of moles of F₂ (n) = PV/RT = (1.2 atm)(18.3 L)/(0.0821 L.atm/mol.K)(299 K) = 0.895 mol.
- Now, we can find the no. of moles of NaCl is needed to react with 0.895 mol of F₂:
<em><u>Using cross multiplication:</u></em>
2 mol of NaCl is needed to react with → 1 mol of F₂, from stichiometry.
??? mol of NaCl is needed to react with → 0.895 mol of F₂.
∴ The no. of moles of NaCl needed = (2 mol)(0.895 mol)/(1 mol) = 1.79 mol.
Answer:
3) Warm Temperatures and High pressures
Explanation:
This is the typical characteristic of southern air masses moving north
