Answer:
1. 67.2 kJ/mol
Explanation:
Using the derived expression from Arrhenius Equation
Given that:
time 
= 8.3 days = (8.3 × 24 ) hours = 199.2 hours
time 
= 10.6 hours
Temperature 
= 0° C = (0+273 )K = 273 K
Temperature 
= 30° C = (30+ 273) = 303 K
Rate = 8.314 J / mol
Since 
Then we can rewrite the above expression as:
Answer:
The dog should be given half of 100 mg tablet in the morning and another half of 100 mg tablet in an evening.
Explanation:
Weight of the dog = 50 pounds = 22.68 kg
1 kg = 2.205 pounds
Amount of daily dose prescribed by doctor = 4.4 mg/kg
Total mount of dose = 4.4 mg/kg × 22.68 kg = 99.79 mg
99.79 mg ≈ 100 mg
49.89 mg ≈ 50 mg
So, according to doctor prescription dog should be given half 100 mg tablet in the morning and another half of 100 mg tablet in an evening.
The equation for density is mass/volume. Make sure your units match what is given in the problem.

<h2>Answer:</h2>
The mass of the system will remain the same if there is no conversion of mass to energy in the reaction.
<h3>Explanation:</h3>
- If the system is closed, then according to the law of mass conservation the mass of the reaction system will remain the same.
- <u><em>Law of conservation of the mass: In simple words, it is described as the mass of a closed system can never be changed, it may transfer from one form to another or change into energy.</em></u>
- But if the reaction involves energy transfer like heat or light production, in this case, the mass can be changed.
