Answer: <span>If a small amount of br2 is added to an aqueous solution of an unknown monosaccharide, the reddish-brown color of br2 will disappear if the monosaccharide is
<u>an Aldose</u>.
Explanation: This happens because the Aldose contains a carbonyl group called Alsedyde. Bromine being a oxidizing agent oxidizes the aldehyde functional group to Carboxylic Acid moiety. While this test is not positive in case of Ketonic Functional group.</span>

Answer:
2.74 × 10⁸ M⁻¹.s⁻¹ = 2.74 × 10⁸ L.mol⁻¹.s⁻¹
Explanation:
Let's consider the following second-order reaction.
NO(g) + F₂(g) → NOF(g) + F(g)
We can find the rate constant (k) using the Arrhenius equation.

where,
- T: absolute temperature (695°C + 273.15 = 968 K)

They have different charges and different masses.
Explanation:
Atom Protons Electrons Neutrons
a 6 6 6
R 7 8 7
The two atoms have different masses and different charges.
The mass of an atom is the sum of its number of protons and neutrons.
The charge is the difference between protons an electrons in the atom.
For atom a;
Mass = 6 + 6 = 12
charge = 6 - 6 = 0
For R:
mass = 7+ 7 = 14
charge = 7 - 8 = -1
We see that they have different masses and different charges.
