Answer:
Belong to the same group.
Explanation:
Different elements are most likely to react in similar ways when they belong to the same group.
This is because the elements in the same group always have similar number of valence electrons which implies that they all have the same number of electrons in their outermost shell. For example,barium (Ba), beryllium (Be), calcium (Ca), magnesium (Mg), radium (Ra), strontium (Sr) all have 2 electrons in their outermost shell and thus they belong to group 2 of elements which are known as Alkaline earth metals and they all tend to react in the same manner with other substances
<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
Answer:
In a classroom, the comparison that a teacher would most likely use for describing a mole is: jar of jellybeans and a gram of salt crystals.
Explanation:
The acceleration is equal to force divided by mass which would be 100 / 50 which is 2 m/s2
The answer is so you do not overheat
