Answer:
Ba(NO₃)₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)
Explanation:
The equation bellow can be explained by the dissociation of each specie:
Ba(NO₃)₂ (aq) → Ba²⁺ (aq) + 2NO₃⁻ (aq)
H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)
The reaction will lead to the formation of solid barium sulfate and nitric acid.
Answer:
Electrons, they circle the nucleus.
Answer:
The protons and electrons are attracted to each other because they are oppositely charged particles.
Explanation:
Protons have a positive charge and electrons have a negative charge, opposites attract.
Answer:
A car speeds up from 0 km/hr to 100 km/hr in 6 seconds.
Explanation:
Answer:
3 moles
Explanation:
This question is on stoichiometry of reactions
Given
2H₂ +O₂⇒2H₂O-------------------the equation is balanced
<u>Find the mole ratio</u>
2H₂ +O₂⇒2H₂O
2 1 2
O:H = 2:1---------------------------------every mole of hydrogen requires two moles of oxygen to complety react
Thus given 6 moles of hydrogen;
O:H
?:6
=6/2=3 moles
