<u>Answer:</u> The weight of water bed in pounds is 1850.16 lb
<u>Explanation:</u>
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 210 cm
b = breadth of cuboid = 160 cm
h = height of cuboid = 25 cm
Putting values in above equation, we get:
(Conversion factor: 
)
To calculate the mass of waterbed, we use the equation:
Density of waterbed = 
Volume of waterbed = 
Putting values in above equation, we get:
Hence, the weight of water bed in pounds is 1850.16 lb
To predict the solubility of the compounds you should base on solubility tables.
I used one from wikipedia. If you google "solubility table" you will find this table as first option.
There I found that nickel, potassium and sodium chlorides are very soluble with solubilities of two digits. While lead clhoride has a solubility close to 1 g per 100 g of water. Then lead is the ion that will precipitate with certainty.
Answer:
I think the answer is A.
please give thanks if it helps
and sorry if it doesn't help.
I believe it's ;
<span>one truck load is 2.5*1.5*1 = 3.75m^3 </span>
<span>7/3.75 = 1.86 loads, </span>
<span>so 2 trips must be made.
Hope this helped! :)</span>
