What do you look at to tell the reactivity of an atom?

Chemistry

tia_tia [17]3 years ago
8 0

Answer:

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.

Use the equation to determine what mass of FeS must react to form 326 g of FeCl2.
iogann1982 [59]

Answer:

We need 226 grams of FeS

Explanation:

Step 1: Data given

Mass of FeCl2 = 326 grams

Molar mass FeCl2 = 126.75 g/mol

Step 2: The balanced equation

FeS + 2 HCl → H2S + FeCl2

Step 3: Calculate moles FeCl2

Moles FeCl2 = 326 grams / 126.75 grams

Moles FeCl2 = 2.57 moles

Step 4: Calculate moles FeS needed

For 1 mol H2S and 1 mol FeCl2 produced, we need 1 mol FeS and 2 moles HCl

For 2.57 moles FeCl2 we need 2.57 moles FeS

Step 5: Calculate mass FeS

Mass FeS = 2.57 moles * 87.92 g/mol

Mass FeS = 226 grams FeS

We need 226 grams of FeS

The mass of Jupiter is 300 times the mass of the earth. Jupiter orbits the sun with Jupiter = 11.9 yr in an orbit with Jupiter =
kondaur [170]

The orbital period is proportional to r^(3/2) and does not depend on the satellite's mass. Any object at Jupiter's position will have the same orbital period regardless of mass. The correct answer is 11.9 yr. <u>Option C.</u>

As the Earth rotates on its axis creating day and night, it travels around the Sun in an elliptical orbit taking about 365 1/4 days to complete. The Earth's rotation axis is tilted with respect to the orbital plane. This creates seasons. The elliptical nature of the Earth's orbit is due to the first forces pushing the Earth away from the Sun's disk.

The momentum of this throw being greater the Earth's orbit would have been more elliptical or it might have been completely ejected from the solar system forever. The Earth's orbit defines a two-dimensional plane called the Ecliptic. It takes about 365 days for the earth to revolve around the sun. After years of analysis, Kepler found that Mars' orbit was likely elliptical, with the Sun at one of his focal points of the ellipse. This led Kepler to discover that all planets orbit the Sun in elliptical orbits and that the Sun is at one of his two focal points.
