3 0

The overall charge on this ion is -3. Neutrons don’t carry a charge, while protons and electrons carry a net +1 and -1 charge, respectively. In this case, the electrons outweigh the protons by 3, making the overall charge -3.

Hope this helps!

Select the correct answer. A student places a sample of white sodium bicarbonate powder in a test tube and heats it. The student
inessss [21]

Answer is: D. It is not sodium bicarbonate.

Balanced chemical reaction of heating sodium bicarbonate:                    2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O.

This is chemical change (chemical reaction), because new substances are formed (sodium carbonate, carbon(IV) oxide and water), the atoms are rearranged, so there is no sodium bicarbonate (NaHCO₃) in the test tube.

This is a reaction going on in your muscle cells right this very minute:The enzyme triose phosphate isomerase catalyzes this rea
Arisa [49]

Explanation:

The given reaction is as follows.

       E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P

Here, [E] = triose phosphate isomerase = 0.1 nm = 0.1 \times 10^{-9}m

         [S] = Dihydroxy acetone phosphate = 5 \mu m = 5 \times 10^{-6}m

         [P] = Glyceraldehyde-3-phosphate = 2 \mu m = 2 \times 10^{-6}m

Therefore, velocity of the reaction will be as follows.

          v = \frac{d[P]}{dt} = \frac{K_{2}[E][S]}{K_{M} + [S]}

where, K_{M} = Michaelic menten constant = \frac{K_{1} + K_{2}}{K_{1}}

            v = \frac{900 \times 0.1 \times 10^{-9}m \times 5 \times 10^{-6}m}{10^{-5} + 5 \times 10^{-6}}

               = 30 \times 10^{-9} m

or,            = 30 nm/s

Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.

Which of the following is the balanced equation for P + O2 → P2O5? Question 3 options: A) 4P + O2 → 2P2O B) P + 5O2 → 2P2O5 C) 4
Luden [163]

Given equation:

P + O2 → P2O5

In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product

Reactants                                            Products

P = 1                                                       P = 2

O = 2                                                     O = 5

The balanced equation would be:

4P + 5O2 → 2P2O5

Reactants                                            Products

P = 4                                                      P = 4

O = 10                                                    O = 10

Ans: D)
