Answer:
The answer to your question is 471.2 g
Explanation:
Data
moles of Cu(HCO₃)₂ = 2.54
mass of Cu(HCO₃)₂ = ?
Process
1.- Calculate the molar mass of Copper (II) bicarbonate
Cu(HCO₃)₂ = (1 x 63.5) + (2 x 1) + (2 x 12) + (6 x 16)
= 63.5 + 2 + 24 + 96
= 185.5 g
2.- Use proportions and cross multiplication to find the mass
185.5 g of Cu(HCO₃)₂ ------------- 1 mol
x ------------- 2.54 mol
x = (2.54 x 185.5) / 1
x = 471.2 g
C5H10O5 would weight a total of 2.312 kilograms.
Iodine reacts to amylose. Amylose is a polychloride found in starches when combined with iodine the substance then becomes blue. This is because the iodine is becoming iodide.

Answer:
<h2>2 m</h2>
Explanation:
The wavelength of a wave can be found by using the formula
where
c is the speed of the wave
f is the frequency
From the question
c = 5 m/s
f = 2.5 Hz
We have
We have the final answer as
<h3>2 m </h3>
