Answer:-

People with diabetes must monitor their blood glucose levels constantly.

Blood glucose levels are nowadays measured by the help of enzyme glucose oxidase. The enzyme glucose oxidase catalyzes the oxidation of glucose to gluconic acid.

By this way all of the glucose is measured at one time. At the same time hydrogen peroxide is produced.

The hydrogen peroxide reacts with a second color producing chemical. The concentration of the glucose can be related to the intensity of color produced

What is the electronegativity of this and how do you get it?

MrMuchimi

Answer:

elecreonegativity is the attraction of a bonded atom for the pair of electrons in a covalent bond. this can occur if:

- the nuclear charges are different

- the atoms are different sizes

- the shared pair of electrons are closer to one nucleus than the other

Which of these describes a Mole in Chemistry?

olya-2409 [2.1K]

Answer: Thus the correct option is D. All of the above describe a mole

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass in grams.

1 mole of every substance contains avogadro's number $6.023\times 10^{23}$ of particles.

Mole is the S.I unit for measuring the amount of substance. It is often used to measure large number of particles.

Thus the correct option is D. All of the above describe a mole

Ex 1) 45.2 g of Zn = _____ moles Zn<br><br> Ex 2) 0.568 moles Ag = _____ grams Ag

Jlenok [28]

the molar mass of Zn is 65

number of mole(n)=reacting mass/molar mass
n=45.2/65
=0.70g/mol

2.the molar mass of Ag is 108

0.568=m/108
then cross multiply
m=0.568×108
m=61.3g
