2.77mg caffeine / 1oz12oz / 1canLethal dose: 10.0g caffeine = 10,000mg caffeine First, find how much caffeine is in one can of soda, then divide that amount by the lethal dose to find the number of cans. (2.77mg caffeine / 1oz) * (12oz / 1can) = 33.24mg caffeine / 1can. (10,000mg caffeine) * (1can / 33.24mg caffeine) = 300.84 cans. Since we can't buy parts of a can of soda, then we have to round up to 301 cans. Notice how all the values were set up as ratios and how the units cancelled.
Answer:
- <u><em>Option D. qsys = - qsurr</em></u>
Explanation:
The symbol q is used to denote heat energy.
Considering positive the heat absorbed and negative the heat released:
- <em>qsys</em> is the heat absorbed by the systme
- <em>qsurr</em> is the heat absorbed by the surroundings
When the system does not do work on or receive work from the surroundings, the first law of thermodynamics states that:
- <em>qsys </em>+ <em>qsurr</em> = 0
From which:
- <em>qsys = - qsurr ← </em>answer
That is the option D.
That means that, the heat abosorbed by the system (if <em>qsys</em> is positive) equals the heat released by the surroundings, or the heat released by the system (if <em>qsys</em> is negative) equals the heat absorbed by the surroundings.
Yes because an organic compound is any member of large class of gaseous liquid or solid chemical compound whose molecules contains carbon
