vaieri [72.5K]3 years ago
5 0

Answer:When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. However, these are not definite indicators.

Explanation: In a chemical reaction, there is a change in the composition of the substances. The following are indicators of chemical changes:

Change in Temperature

Change in Color

Noticeable Odor (after reaction has begun)

Formation of a Precipitate

Formation of Bubbles

What is an example of potential energy and kentic energy?
lana [24]
Potential energy is stored energy. Kinetic energy involves movement.

If a ball is on the top of a hill, it has the most potential energy on the very top of the hill. The kinetic energy is also 0 at this point.

If the ball rolls down the hill, potential energy decreases while kinetic increases.

Which component is missing from the process of photosynthesis? Carbon Dioxide + Water + _________ → Glucose + Oxygen Group of an
telo118 [61]

Answer:

Sunlight

Explanation:

Photosynthesis is the process where by plants manufacture their own food through conversion of carbon(iv)oxide and water in presence to sunlight to produce glucose and oxygen as by product.

The reaction is photo-catalyzed and would only take place in the presence of sunlight.

6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂

Consider the following system at equilibrium where H° = 111 kJ/mol, and Kc = 6.30, at 723 K.
Rashid [163]

Answer:

1) The value of Kc:

C. remains the same.

2) The value of Qc:

A. is greater than Kc.

3) The reaction must:

B. run in the reverse direction to restablish equilibrium.

4) The concentration of N2 will:

B. decrease.

Explanation:

Hello,

In this case, by means of the Le Chatelier's principle which is based on the shift a chemical reaction could have under some modifications, we have:

1) The value of Kc:

C. remains the same, since it just depend the reaction's thermodynamics as it is computed via:

ln(K)=\frac{\Delta _RG}{RT}

2) The value of Qc:

A. is greater than Kc, since the reaction quotient is:

Qc=\frac{[N_2][H_2]^3}{[NH_3]^2}

Thus, the lower the concentration of ammonia, the higher Qc, making Qc>Kc.

3) The reaction must:

B. run in the reverse direction to restablish equilibrium, since ammonia was withdrawn and should be regenerated to reach the equilibrium.

4) The concentration of N2 will:

B. decrease, since less reactant is forming the products.

Best regards.
