Atoms that have different numbers of neutrons than protons and electrons are called isotopes.
Answer:
It would be A, B, and C.
Explanation: This is because radio waves are the longest and gamma rays are the shortest wavelengths. Visible light is in between infrared and ultraviolet rays.
Gamma rays and x-rays are both part of the electromagnetic spectrum.
Hello devin ...<span>The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains </span>6.022<span> X </span>1023 atoms<span>, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams....i hope this helps you out</span>
<u>Answer:</u> The amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles
<u>Explanation:</u>
We are given:
Moles of oxygen gas = 9.3 moles
The chemical equation for the reaction of oxygen gas and hydrogen sulfide follows:
<u>For hydrogen sulfide:</u>
By Stoichiometry of the reaction:
3 moles of oxygen gas reacts with 2 moles of hydrogen sulfide
So, 9.3 moles of oxygen gas will react with = of hydrogen sulfide
<u>For sulfur dioxide:</u>
By Stoichiometry of the reaction:
3 moles of oxygen gas produces 2 moles of sulfur dioxide
So, 9.3 moles of oxygen gas will produce = of sulfur dioxide
Hence, the amount of hydrogen sulfide needed is 6.2 moles and amount of sulfur dioxide gas produced is 6.2 moles
