It is adirect requirement that all properties have direction and size...hope this helps, also this may help too!

<span>Interaction pair forces...i.e. no force is ever a "one way street". If object A applies a force to object B, then object B applies a force of same magnitude and almost always opposite in direction on object A.</span>

Answer:

(a) Increasing the temperature adds heat which is a reactant shifting the equilibrium rightwards.

(b) Pressure has no effect since the change in the number of moles is zero.

Explanation:

Hello,

In this case, one could represent the given reaction as:

$N_2(g)+O_2(g)+ \Delta _rH \leftrightarrow 2NO$

Since it is endothermic. Thus, solving the (a) statement, one identifies the heat as a reagent, that is why the reaction cools down as it progress, therefore, by increasing the temperature, heat is added, that is, a reagent is added, which shifts the equilibrium rightwards, in other words, more NO is produced so its concentration increases.

Furthermore, for the (b) statement, since the change in the number of moles is zero, based on the stoichiometric coefficients as shown below:

$\Delta \nu =2-1-1=0$

Such value implies that the pressure has no effect on the concentration, taking into account the following form of the law of mass action:

$Kp=Kc(RT)^{\Delta \nu }$

Thus, since $\Delta \nu =0$ , $Kp=Kc$ , so no effect in concentration is due to the pressure.

Best regards.

The unbalanced equation below shows the reaction between sodium and water. In the reaction,

NISA [10]

Answer:

41.4 g

Explanation:

2Na(s) + 2H2O (l) ----> 2NaOH ( aq) + H2 (g)

According to the above balnced chemical equation the ratio between moles of H2 gas formed to moles of Na used up is 1:2

Molar mass ( Mass of 1 mol) Of H2 gas is 2 gmol-1

So in 1.8 g of H2 0.9 mol should be present

Therefore no. of moles of Na used should be 2× 0.9 = 1.8 moles

Molar mass of Na= 23 gmol-1

So mass of 1.8 mol of Na = 1.8× 23 g = 41.4g

3. When the hydronium ion concentration of a solution is 1x10-4 M, What

rewona [7]

Answer:

pH = 4

Solution is acidic

Explanation:

Given data;

Hydronium ion concentration = 1 × 10⁻⁴ M

pH of solution = ?

Solution:

pH = -log [H₃O⁺]

pH = -log [ 1 × 10⁻⁴ ]

pH = 4

According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.
