Jar contain 0.400mole of H2sthen how many gram of H and S are there​

H = 0.800g

S = 12.8g

Explanation:

Each mole of H2S contains 2 moles of H and 1 mole of S

so .400 mole of H2S will contain .800 mole of H and .400 mole of S

Mass = mole x Mr

Mass H = .800(1) = .800g

Mass S = .400(32) = 12.8g

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
