The investigation was carried out to explore the effect of amylase on the starch that is present in a substance. The IKI solution reacts with starch to give a dark blue color.
We wait 10 minutes before adding the IKI solution to give the amylase sufficient time to act on the starch present, so that a false negative for the presence of starch is not obtained.
Hello!
We have the following measurement data of a room:
a = 5 m → 500 cm
b = 20000 mm → 2000 cm
c = 1000 cm
<span>What is its volume in cubic cm?

Hello!
We have the following data:
v (volume) = ? (in L)
n (number of mols) = 1,5 mol
T (temperature) = 22 ºC
First let's convert the temperature on the Kelvin scale, let's see:
TK = TºC + 273,15
TK = 22 + 273,15
TK = 295,15
P (pressure) = 100 kPa → P = 100000 Pa → P ≈ 0,987 atm
R (gas constant) = 0,082 atm.L / mol.K
<span>We apply the data above to the Clapeyron equation (gas equation), let's see:
</span>
I hope this helps. =)
Answer:
Mixtures contain 2 solid substance and other mixtures are soluble in a particular liguid solvent ans so others constituent is insoluble in it.
Explanation:
The main difference between substrate level phosphorylation and oxidative phosphorylation is that substrate level phosphorylation is a direct phosphorylation of ADP with a phosphate group by using the energy obtained from a coupled reaction whereas oxidative phosphorylation is the production of ATP from the oxidized ...
