A female bear leaves her bear cubs in their den to go out in search of food. She travels one mile in 30 minutes, heading east. S

Vinil7 [7]

Answer:

Points of acceleration:

1. When female bear goes quickly

2. After becoming tired, when she becomes slow

3. When she changes direction from east to north

4.When she slows down when she reaches the river bed

5. When she turns around

6.When she increases speed to travel southwest to return home

7. When she comes to a stop at home

Explanation:

1. When she is going quickly she is increasing her velocity thus positively accelerating

2. When she becomes slow, she is having negative acceleration.

3. When there is a change in direction of velocity there is an acceleration.

4. Again negative acceleration when she comes to a stop at the river bed

5. Turning around to the southwest direction requires acceleration

6. To increase the velocity to reach home, positive acceleration

7. To decrease the velocity to stop upon reaching home, negative acceleration

A mixture is made by combining 1.49 lb of salt and 3.82 lb of water.

Pavel [41]

Answer:

28%

Explanation:

concentration=(solute mass/solution mass)*100

C=concentration

md-solute mass

ms-solution mass

the solution mass is equal to the sum of the solute and solvent mass

ms=3.82+1.49=5.31lb

c=1.49/5.31 * 100=0.28*100=28%

El pH de una solución acuosa 10^-14 M de ácido acético, a 25°C, es igual a, teniendo en cuenta que Ke = 1.76x10^-5

frez [133]

Answer:

$pH=14$

Explanation:

Hola!

En este caso, consideramos que la disociación de ácido acético ocurre:

$CH_3COOH\rightarrow CH_3COO^-+H^+$

Así, mediante la solución del equilibrio ácido, podemos calcular la concentración de iones hidronio que posteriormente sirven para calcular el pH de la solución, por tal razón, debemos calcular el equilibrio dada la constante de equilibrio y por medio de la ley de acción de masas en términos del cambio $x$ como cualquier problema de equilibrio:
