Explanation:
1.
YES
K2SO4(aq) + Ba(NO3)2(aq) --> Ba(SO4)2(s) + 2KNO3(aq)
Net ionic equation
2SO4^2-(aq) + Ba2+(aq) --> Ba(SO4)2(s)
2.
NO
No precipitate is formed because KNO3, MgSO4, K2SO4 and Mg(NO3)2 all are soluble.
3.
YES
BaCl2(aq) + Na2(SO4)(aq) --> BaSO4(s) + 2NaCl(aq)
Net ionic equation:
Ba2+(aq) + SO4^2-(aq) --> BaSO4(aq)
4.
Ni2+(aq) + S2-(aq) ---> NiS(s)
More than one million Earths could fit inside the Sun if it were hollow. The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi.
Answer:
4.65 L of NH₃ is required for the reaction
Explanation:
2NH₃(g) + H₂SO₄(aq) → (NH₄)₂SO₄(s)
We determine the ammonium sulfate's moles that have been formed.
8.98 g . 1mol / 132.06 g = 0.068 moles
Now, we propose this rule of three:
1 mol of ammonium sulfate can be produced by 2 moles of ammonia
Therefore, 0.068 moles of salt were produced by (0.068 . 29) / 1 = 0.136 moles of NH₃. We apply the Ideal Gases Law, to determine the volume.
Firstly we do unit's conversions:
27.6°C +273 = 300.6 K
547.9 mmHg . 1 atm / 760 mmHg = 0.721 atm
V = ( n . R . T ) / P → (0.136 mol . 0.082 L.atm/mol.K . 300.6K) / 0.721 atm
V = 4.65 L
Answer:
Both cones and flowers produce seeds and are used for reproduction. ... The male cones release pollen which is carried by the wind to a female cone. A pollen tube is formed and pollen is transferred to fertilize the female cone's egg
