The following are neutral salts: NANO3, BaBr2 AND Ba[OH]2.
Neutral salts are those salts that are formed when a strong base react with a strong acid. In those neutralization reactions, the base completely neutralize the acid to form a neutral salts.
“The Earth’s lithosphere is thinner than its asthenosphere”, the statement correctly compares the thicknesses of Earth’s layers
Answer: Option D
<u>Explanation:
</u>
The outermost parts of the Earth composed of crust and a part of the upper mantle is termed as lithosphere. And asthenosphere is positioned below lithosphere. The bottom layer of lithosphere has the parts of the upper crust.
So the highly viscous and ductile region in the remaining part of the upper crust forms the asthenosphere below the lithosphere. The upper crust in the lithosphere region contain elastic properties while the upper crust in the asthenosphere is ductile in nature. Thus the statement that lithosphere is thinner than asthenosphere is true as it is located at the surface.
Answer:
Mass of SO₂ can be made from 25.0 g of Na₂SO₃ and 22 g of HCl = 12.672 g
Explanation:
SO₂( sulfur dioxide) can be produced in the lab. by the reaction of hydrochloric acid & sulphite salt such as sodium.
the balanced chemical equation is as follows
Na₂SO₃ + 2 HCl → 2 NaCl + SO₂ + H₂O
Moles of Na₂SO₃ = 
Moles of HCl = 
using mole ratio method to find limiting reagent
For sodium sulfite 
for HCl 
since <u>sodium sulfite</u> is <u>limiting reactant</u> for above chemical reaction
1 mole of Na₂SO₃ produce 1 mole of SO₂
0.198 mole of Na₂SO₃ produce 0.198 mole of SO₂
∴ Mass of SO₂ produce = mole x molar mass of SO₂
= 0.198 x 64
= 12.672 g
The atomic mass number does<span> not change because a </span>beta<span> particle has a much smaller </span>mass<span> than the </span>atom<span>. The </span>atomic number<span> goes up because a neutron has turned into an extra proton. </span>Beta decay<span> is fundamentally different from alpha </span>decay<span>.
