1.2 moles of (nph4)3po3 is.......159.6 grams
Answer:
a) But-1-ene
b) E-But-2-ene
c) Z-But-2-ene
d) 2-Methylpropene
Explanation:
In this case, if we want to draw the <u>isomers</u>, we have to check the<u> formula </u>
in this formula we can start with a linear structure with 4 carbons. We also know that we have a double bond, so we can put this double bond between carbons 1 and 2 and we will obtain <u>But-1-ene.</u>
<u />
For the next isomer, we can move the double bond to carbons 2 and 3. When we do this can have two structures. When the methyl groups are placed on the same side we will obtain <u>Z-But-2-ene</u>. When the methyls groups are placed on opposite sides we will obtain <u>E-But-2-ene.</u>
<u />
Finally, we can use a linear structure of three carbons with a methyl group in the middle with a double bond, and we will obtain <u>2-Methylpropene.</u>
<u />
See figure 1 to further explanations.
I hope it helps!

Around 24.85 miles per hour
, divide the length value by 1.60
Answer:
The car travel 660 feet
Explanation:
First convert the Speed into <u>Feet/sec</u>
Speed of the car = 90 mi/hr
1 mi = 5280 ft
In 90 miles = 90 x 5280 = 475,200 feet
1 hr = 60 min
1 min = 60 sec
So ,
1 hr = 60 x 60 sec = 3600 sec
The speed is defined as the distance traveled by the object in unit time. The formula of speed is :

... given

Speed = 132 ft/sec
Now, time = 5 sec



Distance = 660 feet
The classification of it being a metal, nonmetal, or metalliod will be useful in the process of elimination to determine what it is. Then for the second test, meauring the atomin radius will narrow it down quicker to the mystery elemet's name.
Since you determined what part of the periodic table it's on, then when measuring the atomic radius, you should be able to pinpoint what the element is more surely.
