Answer:
yes
Explanation:
Kids like fun things, and school is not fun , so if kids got to go to school on a zipline, attendance would be through the roof!
Answer:
SO₄(aq) + Ba(aq) + ----> BaSO₄(s)
Explanation:
(aq) will always become 2 ions
balancing the equation
Na₂SO₄(aq) + BaCl₂(aq) ----> BaSO₄ + 2NaCl
note how there is the same amount of each element on both sides except for Na and Cl. the left side has 2 times the amount of the right side. All I needed to do to balance was add the 2 coefficient to NaCl product on right side since Na and Cl are together and not in separate compounds.
now rewriting (NaCl is aq since all compounds with Na are aqueous)
barium sulfate is the solid formed
rewriting the equation: (subscripts of single elements become coefficients, polyatomic subscripts stay)
2Na(aq) + SO₄(aq) + Ba(aq) + 2Cl(aq) ----> BaSO₄(s) + 2Na(aq) + 2Cl(aq)
net ionic: removing any substance seen on both sides
SO₄(aq) + Ba(aq) + ----> BaSO₄(s)
They are volcanoes
The difference between a quiet and explosive eruption is the silica content. In a quiet eruption, the magma is low in silica, allowing the magma to flow out gently. In an explosive eruption, the magma is high in silica, which causes the magma to be thick and sticky.
1 mole MgS2O3=24+2*32+3*16=136g
229g MgS2O3 = 229/136=1.6838 moles
