7 0

Answer:

1 O₂

Explanation:

In the combustion reaction of hydrogen, oxygen combines with hydrogen to form water as the product of the reaction

Equation of reaction:

2H₂ + O₂ → 2H₂O

From the equation of reaction, it is evident that 2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles of water.

Therefore the coefficient of oxygen in the equation is 1.

Predict the sign for AS for each of the following systems: Water freezing Water evaporating Crystalline urea dissolving Assembly
djyliett [7]

Answer:  1.  Water freezing : \Delta S is -ve.

2. Water evaporating : \Delta S is +ve.

3. Crystalline urea dissolving : \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids: \Delta S is -ve.

5.  Assembly of a protein from individual amino acids: \Delta S is -ve.

Explanation:

Entropy is defined as the measurement of degree of randomness in a system.

It is represented by symbol S and we can only measure a change in entropy which is given by \Delta S.

If there is decrease in randomness , the sign for \Delta S is -ve and If there is increase in randomness , the sign for \Delta S is +ve.

1.  Water freezing: Entropy decreases as we move from liquid state to  to solid state and thus \Delta S is -ve.

2. Water evaporating : Entropy increases as we move from liquid state to  gaseous state and thus \Delta S is +ve.

3. Crystalline urea dissolving : The molecules convert from solid and ordered state to aqueous phase and random state. Thus the entropy increases and thus \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids:  random lipids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

5. Assembly of a protein from individual amino acids: random amino acids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

When a catalyst is added to a reversible reaction in equilibrium state the value of equilibrium constant
Sergio [31]

Explanation:

The value of equilibrium constant doesn't change when a catalyst is added.

Equilibrium constant depends on Concentration of reactants , Pressure and Temperature.

Propane, the gas used in barbeque grills, is made of carbon and hydrogen. Will the atoms that make up propane form covalent bond
Masteriza [31]
Hydrocarbons are molecules that contain only carbon and hydrogen. Due to carbon's unique bonding patterns, hydrocarbons can have single, double, or triple bonds between the carbon atoms. The names of hydrocarbons with single bonds end in "-ane," those with double bonds end in "-ene," and those with triple bonds end in "-yne". The bonding of hydrocarbons allows them to form rings or chains.
