Answer:

When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.

The mass of each WtWt isotope is measured relative to C−12C−12 and tabulated below. Use the mass of C−12C−12 to convert each of

Nadya [2.5K]

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296 = 24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

$M\times \frac{1}{12 amu}=24.6622$

$M=24.6622\times 12 amu=295.9464 amu$

The atomic mass of Wt-296 is 195.9464 amu.

Is oxygen a necessary reactant for oxidation reaction

storchak [24]

Answer:

Oxidation: A process in which an atom loses an electron and therefore increases its oxidation number. ... So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction).

The proposed mechanism for a reaction is 1. ClO-(aq) + H2O(l) => HClO(aq) + OH-(aq) SLOW 2. I-(aq) + HClO(aq) => HIO(aq) +

HACTEHA [7]

Answer:

The correct answer is option A.

Explanation:

Step 1 : Slow

$ClO^-(aq) + H_2O(l)\rightarrow HClO(aq) + OH^-(aq)$

Step 2: Fast

$I^-(aq) + HClO(aq)\rightarrow HIO(aq) + Cl^-(aq)$

Step 3: Fast

$OH^-(aq) + HIO(aq)\rightarrow H_2O(l) + IO^-(aq)$

When there is a recation which is taking place in a more that single steps than the rate of the reaction is determined by the slowest step occurring in the reaction mechanism.

So, according to question step 1 is slow step which means that rate of the reaction will be :

$R=k[ClO^-][H_2O]$
