Answer:
825 g
Step-by-step explanation:
Here's my work:
500g Cl2 l 1mol Cl2 l 2 mol NaCl l 58.5 g NaCl
l 71 g Cl2 l 1 mol Cl2 l 1 mol NaCl
= 823.94 - the rounding can be a little off
The first thing you have to do is convert the 500 g of Cl2 into moles. So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71. now on the third column you are comparing the mol ratios of the equation. The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a coefficient of 2 in front of NaCl so that means there is 2 moles. Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl . You multiply across the top and then divide that number by the bottom row.
What do you want exactly i don’t understand the question. Comment and ill solve it
B & C would be your answer because 3^-3 would turn into a fraction, 1/3^3 which is the same as C.
Answer:
I think its −1306800x+91040454
Step-by-step explanation:
Let's simplify step-by-step.
32+100(−3x+209)(662)+11+34
Distribute:
=32+−1306800x+91040400+11+34
=9+−1306800x+91040400+11+34
Combine Like Terms:
=9+−1306800x+91040400+11+34
=(−1306800x)+(9+91040400+11+34)
=−1306800x+91040454
Answer:
5.75 ft on each side
Step-by-step explanation:
6ft*8ft=48ft
71ft-48ft=23ft
23-4=5.75ft
