It is based on the law of conservation of energy , which says that energy is neither created nor destroyed during a chemical reaction . I’m calorimeter , this means that the heat gained by the water in calorimeter must have been released by the sample or reaction taking place in the calorimeter .

It is based on the law of conservation of energy, which says that energy is neither created nor destroyed during a chemical reaction. In calorimetry, this means that the heat gained by the water in the calorimeter must have been released by the sample or the reaction taking place in the calorimeter

True or false reactants are located on the right side of a chemical equation?
poizon [28]

Answer:

The value of the equilibrium constant K depends on: I. the initial concentrations of the reactants. II. the initial concentratio
Elden [556K]

Answer:

None of these

Explanation:

For a reaction;

aA + bB ------>cC + dD

The equilibrium constant K is given as;

K = [C]^c [D]^d/[A]^a [B]^b

The equilibrium constant neither depends on the concentrations of the reactants nor on that of the products.

Let us recall that at equilibrium, the concentrations of reactants and products remain largely constant. This implies that, concentration of species do not appreciably change at equilibrium because the rates of forward and reverse reactions are equal.

Hence, the equilibrium constant neither depends on the initial/final concentrations of the reactants nor on the initial/final concentrations of the products.

Which of the fallowing scientific claims about the bond in the molecular compound HF is most likely to be true?
DENIUS [597]

The bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

The term polar means that there is separation of charges, the bonds will be the more polar the greater the difference in electronegativity between the bonded atoms.

  • In hydrogen fluoride, for example, F is more electronegative than H because its nucleus, with 9 positive charges, attracts e-shares with H more strongly than the nucleus of H, with only one positive charge.

  • Therefore, the e- shared by covalence will be closer to F than to H and the molecule forms a permanent dipole.

Therefore, we can conclude that the bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

Modify how could you charge the electric circuit shown below to allow lightbulb a to stay lit even if lightbulb b is removed fro
gladu [14]

Answer:

<em>An electrical circuit is an unbroken path along which an electrical current occurs and/or will pass. The basic electrical circuit consists of a power supply, two conductive wires (one end of each being connected to each cell terminal) and a small light to which the free ends of the wires leading out of the cell are attached. If the links are made right, the circuit will "close"</em>

The complete balanced equation for the reaction between barium hydroxide and acetic<br> acid is
TiliK225 [7]

Answer:

2 CH3COOH + Ba(OH)2 --> Ba(C2H3O2)2 + 2H2O

To make it less clustered, you can use Ac for C2H3O2.

2 HAc + Ba(OH)2 --> Ba(Ac)2 + 2H2O

The acetic acid reacts with the base barium hydroxide to form the salt barium acetate and water.
