Answer:
the tempeture increases
Explanation:
Zn(s) + CuSO4(aq) � ZnSO4(aq) + Cu(s) An important aspect of these experiments is that they are exothermic.
Answer:
LIBs have had a huge impact on our society. They enabled modern portable electronics such as laptops and mobile phones. And they are now enabling clean and low-carbon transport, be it via electric cars or even flying taxis, and grid-scale storage of renewable energy
Explanation:
Answer:
Explanation:
= Mass of metal = 19 g
= Specific heat of the metal
= Temperature difference of the metal =
V = Volume of water = 150 mL =
= Density of water =
= Specific heat of the water = 4.186 J/g°C
= Temperature difference of the water =
Mass of water
Heat lost will be equal to the heat gained so we get
The specific heat of the metal is .
Answer:
If the half-life of radon-222 is 3.82 days, then how much of a 10.0 gram sample of radon-222 would be left after 7.64 days
✓ 2.50g
Explanation:
The amount of precipitate produced will be proportional to the amount of NH₃ reacted with water to produce NH₄OH.
<h3>What is precipitate?</h3>
Precipitates are the crystal type formation, when the solute is no more dissolving in the solvent.
Imagine mixing 1 tablespoon of Epsom salt with 2 cups of ammonia, the reaction is
2NH₃ + MgSO₄ + 2H₂O → Mg(OH)₂ + (NH₄)₂SO₄
The amount of precipitate produced will be proportional to the amount of NH₃ reacted with water to produce NH₄OH.
