330feet
Explanation:
Given parameter:
Length of field = 110yards
problem:
Convert the given length to feet
Both feet and yard are units of measurement of the length of a body. They describe how long a body is.
1yard = 3 foot
110yard = 3 x 110 = 330feet
A length of 110yards is 330feet

Answer:
5.5 grams
Explanation:
To find how much of the isotope remains, you need to use the half-life equation:
In this equation,
-----> N(t) = remaining mass (g)
-----> N₀ = initial mass (g)
-----> t = time (hrs)
-----> h = half-life (hrs)
You can find the remaining mass by plugging the given values into the equation and solving.
N(t) = ? g t = 30 hrs
N₀ = 22 g h = 15 hrs
<----- Half-life equation
<----- Insert values
<----- Simplify exponent
<----- Solve
<----- Multiply 22 and 0.25
Benzoic acid is able to dissolve in hot solvents. That means that it would not be filtered out by the buchner funnel since the buchner funnel has holes in it that make it so that the solvent can get through but solids can't (the benzoic acid would be dissolved in the solvent and therefore would leave the funnel with the solvent through the holes).
Note that it is important that the solvent is hot. Benzoic acid will start to precipitate out (re crystallize) as soon as the temperature drops which will make it so that some of the benzoic acid would get caught in the buchner funnel.
I hope this helps. Let me know in the comments if anything was unclear.
