Answer:
25 gm would be left
Explanation:
45 hours is 3 half lives
200 gm * 1/2 * 1/2 * 1/2 = 25 gm
Answer:
The molarity of this final solution is 0.167 M
Explanation:
Step 1: Data given
Volume of a 0.100 M HNO3 solution = 50.0 mL
Volume of a 0.200 M HNO3 = 100.0 mL
Step 2: Calculate moles
The final molarity must lie between 0.1M and 0.2M
Moles = molarity * volume
Moles HNO3 in 50mL of a 0.100M solution = 0.05 L *0.100 M = 0.005 mol
Moles HNO3 in 100mL of a 0.200M solution = 0.100 L*0.200 = 0.020mol
total moles = 0.005+0.020 = 0.025 moles in 150mL solution = 0.150L
Step 3: Calculate molarity of final solution
Molarity = mol / volume
Molarity 0.025 moles /0.150 L
Molarity = 0.167M
The molarity of this final solution is 0.167 M
Answer: There are many strategies used to hunt and kill moths. I’ll tell you my way of hunting and killing moths.
Step-By-Step Explanation:
Morning and Afternoon: First, get a sticky trap. You can get it at Target or Walmart. Cover it with moth pheromones or anything you know that can attract the moths. The sticky trap, will stick them to the trap and will eventually die after no being able to escape for a long time.
Nighttime: Buy or Get a lamp and turn it on. This will attract lots of moths and it will help you see them. Then, spray insecticide or insect repellent at the. Lastly, they should die.
Tip: If things get too out of hand with a huge swarm of moths, then call pest control and they will surely get rid of them for you!
Answer:
It depends.
Explanation:
Generally, the presence of more landmasses in the Northern Hemisphere produces continental climates with extreme temperatures that are relatively rare in the Southern Hemisphere due to the abundance of oceans at the southern latitudes north of Antarctica.
If a city has average rainfall and warm temperatures in the Northern Hemisphere, it is logical to assume that, on average, a city at the same distance from the equator in the Southern Hemisphere would have slightly cooler temperatures and more rainfall due to the enhanced maritime effect.
This depends, of course, entirely on the local geography of the city in question, and the results could be completely different based on the actual city given.
