Answer:

I dont know if this is the right subject but i got an A+ on it. It is Life science edgenuity     This is the process part of it

Explanation:

First, I observed all of the arthropods that I would be using in my dichotomous key, Fire Ant, Bee, Butterfly, Dragonfly, Ladybug, Scorpion, Spider, and Wasp. I recorded my observations on a characteristics table that included Legs, Wings, Stinger, Antennae, and Claws.  

Next, I used my observations to create my first question, “Does the arthropod have a stinger?).  

     Then, I Looked over my notes and found the arthropds that have stingers, Fire Ant, Bee, Scorpion, and        Wasp, and sorted them into a Yes group. Also I found the arthropods in my notes that didn’t have stingers, Butterfly, Dragonfly, Ladybug, and Spider, and put them into a No group.  

     After That, I Chose a new question coming off of the Yes group, “Does the arthropod have 6 legs?”. I sorted those the arthropods that did have 6 legs into a Yes group, Fire Ant, Bee, and Wasp.  

     Then, I did the same for The arthropods who didn’t have 6 legs and the only one was Scorpion, so I wrote scorpion in the No group and that Branch was done.  

     Next, I did another question for my very first No group, “Does the arthropod have antennae?” and I sorted the arthropods into the yes and no branches. No group included, Dragonfly and Spider. Yes group included, Butterfly and Ladybug.

     Later, I did a question for the yes group coming off of the 6 legs question, “Does the arthropod have wings?”. The yes group included, Bee and Wasp. The no group included, the Fire Ant only so I wrote down Fire Ant and that branch was concluded.  

     Then, I did a question for the no group coming off of the antennae question, “Does the arthropod hve 8 legs?” and my yes group included spider only so that branch was done. My no group included Dragonfly so that branch was concluded aswell.  

     After That, I wrote a question for the yes group coming off of the wings question, “Does the arthropod have 2 wings?”. My Yes group concluded wit only the Wasp left so I had finished that branch. I finished my no group with a Bee.

     Lastly, I did my last question of the key coming off of the Yes group of the antennae question, “Does the arthropod have 4 wings?”. My no group included a Ladybug and my yes group included a Butterfly.

     In conclusion, My dichotomous key was finished with 8 athropods in each branch alone and now you can use the dichotomous to observe a Fire Ant, Bee, Wasp, Butterfly, Dragonfly, Ladybug, Spider, and Scorpion.  

                                               Please mark me brainliest :) :) :) :) :) :)

What masses of iron(iii) oxide and aluminum must be used to produce 15.0 g iron? what is the maximum mass of aluminum oxide that
defon
1) Chemical reaction:

Fe2O3 + 2Al ---> Al2O3 + 2Fe

2) molar ratios

1 mol Fe2O3 : 2Al : 1 mol Al2O3 : 2 mol Fe

3) Convert 15.0 g of iron into moles

atomic mass Fe = 55.8 g/mol

moles = mass in grams / atomic mass = 15.0 g / 55.8 g/mol = 0.269 mol

4) Use proportions to determine the moles of Fe2O3, Al, and Al2O3

a) 1mol Fe2O3 / 2 mol Fe = x / 0.269 mol Fe

x =

=> x = 0.269 mol Fe * 1 mol Fe2O3 / 2 mol Fe = 0.134 mol Fe2O3

b) 2 mol Al / 2 mol Fe = x / 0.269 mol Fe

=> x = 0.269 mol Al

c) 2 mol Fe / 1 mol Al2O3 = 0.269 mol Fe / x

=> x = 0.269 mol Fe * 1 mol Al2O3 / 2 mol Fe

x = 0.134 mol Al2O3

5) Convert moles to grams

a) Fe2O3

molar mass Fe2O3 = 2* 55.8 g/mol + 3*16g/mol = 159.6 g/mol

mass = molar mass * number of moles

mass = 159.6 g/mol * 0.134 mol = 21.4 g

b) Al

atomic mass = 27.0 g/mol

mass = number of moles * atomic mass = 0.269 mol * 27.0 g/mol = 7.26 g

c) Al2O3

molar mass = 2 * 27.0 g/mol + 3*16.0 g/mol = 102.0g/mol

mass Al2O3 = numer of moles * molar mass = 0.134 mol * 102.0 g/mol = 13.7 g

Answers:

21.4 g Fe2O3

7.26 g Al

13.7 g Al2O3

Jake hangs two balloons from a desk so that they are close together but not touching. Jake rubs one balloon with a wool cloth. H
kari74 [83]
The objects that are rubbed together will create charges among themselves due to friction. 
(1) The balloon rubbed with a wool cloth will be charged. 
(2) If she comb near a small, uncharged object nothing will change. 
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
