Answer:
The stable ion the sulfur would form is the sulfide ion,
Explanation:
When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.
Well, this is obviously an opinion question, so share your opinion. If you are happy that the Agricultural Revolution(s) paved way for the earth to sustain billions of people, then that's great. But, if you wish there were fewer people on the planet, then share that. Of course, both sides have their pros and cons. Just share your opinion. Good luck!
<span>The fossil fuels form from the buried remains of ancient organisms, </span>formed from the remains of dead plants and animals.
<span> These plants and animals that have been converted to crude oil, coal, natural
gas, or heavy oils by exposure to heat and pressure in the earth's
crust over hundreds of millions of years. So, three things that act on decaying organisms to help form fossil fuels are:
-pressure
-heat
-physical and chemical changes
People use fossil fuels products for transportation and heating, many power plants burn coal for heat to turn turbines that generate electrical energy. ...</span>
1) Calculate the number of moles of Cu SO4 . 5H20 by dividing the specified mass by the molar mass.
2) The ratio of production given by the equation is 1 mol of Cu SO4 . 5 H2O to 1 mol of Cu SO4=> 1:1, meaning that the number of moles of Cu SO4 produced is the same number of moles of Cu SO4.5H20 heated.
3) Finally mutiply the number of moles of Cu SO4 by its molar mass and there you have the mass of Cu SO4 produced.
