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!!!
Energy is equal to motion over speed
Based on the data given, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu
<h3>How can molar mass of a gas be obtained from density, temperature and pressure?</h3>
The molar mass of a gas can be obtained from density, temperature and pressure using the formula below:
- molar mass = density × molar gas constant × temperature/pressure
Molar gas constant, R = R = 0.082 L.atm/mol/K.
Temperature = 150 °C = 423 K
Pressure = 785 torr = 1.033 atm
density = 4.93 g/L
molar mass of gas = 4.93 × 0.082 × 423/1.033
molar mass of gas = 165.5 g/mol
Then, molecular weight of the gas = 165.5 amu
Therefore, the molar mass of the gas is 165.5 g/mol while the molecular weight of the gas is 165.5 amu

Answer:
A) positive; added
Explanation:
Based on the reaction:
2NaHCO3(s) + 129kJ → Na2CO3(s) + H2(g) + CO2(g)
<em>2 moles of NaHCO3 requires 129kJ to produce 1 mole of Na2CO3, 1 mole of H2 and 1 mole of CO2.</em>
<em />
That means, the energy must be added being, thus, an exothermic reaction. The exothermic reactions have ΔH >0.
Thus, right answer is:
A) positive; added
