In November 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. The chunk of ice was e

<h2>Answer:</h2>

1.58 × 10∧16 pools.

<h3>Explanation:</h3>

Given:

Length of ice berg= 98 miles = 1557716 meters

Width of iceberg = 25 miles = 40233.6 meters

Thickness of iceberg = 750 ft = 230 meters

Volume of water in a swimming pool = 24,000 gallons = 90850 liters

The volume of the ice berg:

Volume = Length . width . thickness

Volume = 1557716 . 40233.6 . 230 = 1,441, 468, 016, 5248 m3 = 1,441, 468, 016, 5248 × 10 ∧3 L.

1 pool contains liters of water: 90850 liters

1,441, 468, 016, 5248 × 10 ∧3 liters contains = 1/90850 . 1,441, 468, 016, 524.8 × 10 ∧3 .

= 1.100 . 1,441, 468, 016, 5248 × 10 ∧3 L.

= 1.58 × 10∧16 pools.

Hence 1.6 × 10∧16 pools will be filled with that chunk of ice.

how can you make the gravitational force between two 50kg objects less than the gravitational force between two 5kg objects

Paraphin [41]

Explanation:

The gravitational force between two 50kg objects could be less than the gravitational force between a 50kg and a 5kg object if the two 50kg objects are much farther apart.

Consider the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq). Which ions are spectator ions? pls

Marta_Voda [28]

Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$

<h3>What are spectator ions?</h3>

Ions that are not involved in the actual chemical reaction are called spectator ions.

A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.

Hence, Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$
