A substance that is present in a reaction but not used up in the reaction is called a catalyst
<span>Answer: option (4) the same magnitude and the opposite sign.
</span>
Justification:
<span /><span /><span>
</span><span>1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals).
</span>
<span /><span /><span>
2) Protons are positive particles that are inside the nuclus of the atom.
</span><span />
<span>3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom.
</span>
<span /><span /><span>
4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign: (+) + (-) = 0: positive + negative = neutral.</span>
A decrease in population which means animals and plants.
Answer:
2C2H6(g) + 7O2(g) ==> 4CO2(g) + 6H2O(g)
One way to find the limiting reactant is to divide the moles of reactant by the corresponding coefficient in the balanced equation and whichever is less is limiting.
For C2H6 we have 2 moles / 2 = 1
For O2 we have 8 moles / 7 = 1.14
Explanation:
If a reaction mixture contains 8 moles of O2(g) with 2 moles of C2H6(g),which reactant is the limiting reactqnt and what is the mass (in grams) remaining of the reactant in excess?
Answer:
<h3>Reactivity is the ability of matter to react chemically with other substances. Flammability is the ability of matter to burn.</h3>
