How many formula units are in 4.52 moles of H3SO3?<br> Type your answer

lakkis [162]

Answer:

The answer is 98.07848. We assume you are converting between grams H2SO4 and mole. You can view more details on each measurement unit: This compound is also known as Sulfuric Acid. The SI base unit for amount of substance is the mole. 1 grams H2SO4 is equal to 0.010195916576195 mole.

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.

Select the correct statement about isotopes. A. All the isotopes of an element are radioactive. B. Isotopes of the same element

frutty [35]

Answer: Option (B) is the correct answer.

Explanation:

Isotopes are the substances or species that contain same number of protons but different number of neutrons.

As it is known that atomic number means the total number of protons present in an atom. Hence, this also means that in isotopes atomic number of the species is same.

For example, isotopes of hydrogen are $^{1}_{1}H$ , $^{2}_{1}H$ , and $^{3}_{1}H$ .

Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons.

Thus, we can conclude that the statement isotopes of the same element have the same atomic number but differ in their atomic masses, is correct.

The atoms 14N7, 15N7 and 16N7 are?

Dovator [93]

The are isotopes because the atomic number (meaning a same number of protons) is the same but the atomic masses are different. this means they have a different number of neutrons which is what isotopes are.

answer is E- all of these

Which element is classified as an alkali metal?<br> Rb<br> Sr<br> Zr<br> Cl

qwelly [4]

Hi there.

Alkali metals are known as the group 1 elements.

When we know this, we just have to look to group 1 of the periodic table.

Rb (Rubidium) is in group 1; it is classified as an alkali metal.
