How do I answer and do this
Alecsey [184]

a) When the reaction takes place a yellow precipitate will be formed.

b) The law of conservation of mass is true.

<u>Explanation:</u>

a) When a lead nitrate solution is mixed with a potassium chromate solution, a yellow precipitate containing lead forms according to the equation:

Pb(NO_3)_2 (aq) + K_2CrO_4 (aq) → 2 KNO_3 (aq) + PbCrO_4(s).

b) Law of conservation of mass for the given reaction is true.

From the given table we know the mass of reactants and its products.

Law of conservation of mass is a principle when a reaction takes place in a closed system, the mass of the products and reactants in the system doesn't change.

⇒The sum of the mass of the reactants = The sum of the mass of the products.

The sum of the reactants = 128.71+128.97.

                                          = 257.68 g.

The sum of the products = 154.10+103.58.

                                          = 257.68 g.

Thus law of conservation of mass is true for the above reaction.

Directions: Use the words in the word box to complete the following sentences.
NeX [460]

Explanation:

When the forces acting on an object are balanced , there is no change in the object's motion.

A force acting on a resting object can cause the object to move.

On Earth, gravity pulls all objects toward the ground.

When a force acts in the opposite direction of another force, the forces counteract each other.

More than one force acting on a falling object can reduce its downward acceleration

Air resistance is caused by molecules of air pushing against a moving object

A car is traveling at a speed of 65 mi/h. How long does it take to cover a distance of 235 m?
fgiga [73]

Answer:

It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.

Explanation:

Speed of the car = 65 mile/h = 65  1609.34 m/h = 104,607.1 m/h

1 mile = 1609.34 m

Distance covered by the car in t time = 235 m = mile

Speed-\frac{Distance}{Time}

104,607.1 m/h=\frac{\frac{235}{1609.34} mile}{t}

t=\frac{235 m}{104,607.1 m/h}

t = 0.002246 h

1 hour = 3600 seconds

0.002246 h = 0.002246 h × 3600 seconds = 8.09 seconds

It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.

A major chemical spill occurred five years ago at Bakerâs Beach, the worldâs sole nesting ground for Merrick sea turtles, and pr
AfilCa [17]

Answer:

<em>B. Female Merrick sea turtles begin returning to Bakerâs Beach to lay their eggs when they are ten years old.</em>

Explanation:

Firstly, There was an oil spill five years ago-no eggs hatched.

Now, the number of females coming back to the lay eggs has increased somewhat since the last five years.

The theory is that a period of 5 years is sufficient to assess effect on population.

If the breeding cycle has been found to be ten years long, then the impact of the oil spill on the population (as observed by the number of females returning to lay eggs) will only be perceived in the 10th year.

It undermines the argument that the oil spills don't impact the public.
