The answer should be a) always six. The chemical reaction is the process of molecule break down and form again. So the molecule will change but the atom will not change both type and number.

It should be a) always six, because what you start with is what you will end with.

Pepsi [2]

The momentum of the body is 12 m/s.

<h3>What is momentum?</h3>

Momentum is the product of the mass of a body and velocity. According to Newton's second law, the rate  of change of momentum is equal to the impressed force.

The details required to answer the first two questions are missing hence we can't answer those questions. For the last question;

p = mv

m = mass

v = velocity

p = momentum

v = p/m

v =  72,000 kgm/s/6,000 kg

v = 12 m/s

Cups and glasses are taking too long to air dry this could be caused by
lions [1.4K]

Cups and glasses are taking too long to air dry this could be caused by the bad ventilation system.

Bad ventilation, or the lack of air flow.

To make sure that no moisture is left on them.

If the moisture or some water drops are left on glasses or cups.

These water drops leave a strange mark and causes a smell in dishes.

Other reasons of cups and glasses are taking too long to dry than the improper working of ventilation can be:

Humidity in Air, Improper Heat, and use of Soap

Humidity in Air, causes high moisture in air that results in the delay in drying of dishes that may lead to even bad smell and bacterial infection on cups and glasses causing bad health.

PLEASE HELP!! What direction do you predict the addition of a base to the solution containing bromophenol blue will drive the eq
marishachu [46]

Answer:

Below is the clarification of that same particular question.

Explanation:

  • Le Chatlier's theory states that whenever an equilibrium mechanism is disrupted by environmental influences, the program responds by changing the supplies information of its constituents in a somewhat way that the disturbance is invalidated and reaches a stable equilibrium during that disrupted stage, with concentrations of stability differently than ever before.
  • Bromothymol blue seems to be a phenolic subs lone which always allows it to act throughout aqueous solutions as an acidic solution. Being such an acid (weak), it should not add to rapid, as well as introduces a balance with its accompanying but mostly disconnected form.

<u>For that kind of weak diprotic predictor, the standard economic statement can indeed be published as:</u>

    ⇒  H_2In_(aq)\rightleftharpoons In^{2-} +2H^+

  • It could be conclusively proven from either the theory of Le Charlier whereby, that whenever a strong acid becomes applied, the full disorientation of one or the other, through equilibrium formation, induces an increase throughout the medium's proton concentrations.
  • Likewise, it absorbs the protons throughout the media to split water that whenever a solution is added. So, particle concentration throughout the medium is decreasing. To accommodate for this transition, the equilibrium reacts by moving to the correct i.e. causing further dissociation of the optimistic predictor into their dianion through protons, thereby attempting to nullify that perturbation.

Suppose that 0.25 mole of gas C was added to the mixture without changing the total pressure of the mixture. How does the additi
Yanka [14]

Here we have to get the effect of addition of 0.25 moles of gas C on the mole fraction of gas A in a mixture of gas having constant pressure.

On addition of 0.25 moles of C gas, the mole fraction of gas A will be  \frac{moles of gas A}{moles of gas A + 0.25}.

The partial pressure of gas A can be written as P_{A} = x_{A}×P (where x_{A} is the mole fraction of gas A present in the mixture and P is the total pressure of the mixture.

The mole fraction of gas A in a mixture of gas A and C is = \frac{moles of gas A}{moles of gas A + moles of gas C} and \frac{moles of gas C}{moles of gas A + moles of gas C} respectively.

Thus on addition of 0.25 moles of C gas, the mole fraction of gas A will be  \frac{moles of gas A}{moles of gas A + 0.25}.

Which is different from the initial state.
