Balance the chemical equation. (Blank) N2O3 → (Blank) N2 + (Black) O2

Anna71 [15]

The balanced equation is as below

2 N₂O₃ → 2N₂ + 3O₂

<u><em> Explanation</em></u>

According to the law of mass conservation the number of atoms in reactants side must be equal the to the number of atoms in products side.

Therefore the balanced reaction above is balanced since the number of atoms in reactants side are equal to number of atoms in products side.

For there 4 atoms of N in reactants side and 4 in products side.

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

il63 [147K]

<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.

Why is thermal energy from the sun transferred to Earth through electromagnetic waves, instead of any other type of thermal ener

nlexa [21]

Answer: B) Electromagnetic waves can travel through empty space.

Explanation:

Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.

Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.

Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.
