Answer:False, we can sense four tastes, namely salty, sweet, sour and bitter. Acids taste sour. If we want to know if something is an acid, we can just taste it.
Explanation:
Answer:
55.4324℃
Explanation:
Q=cm△t
50J = 0.902J/（g·℃） x 1g x △t
△t =55.4324℃
2ZnS(s)+3O2(g) -> 2Zns(s) + 2SO3(g)
the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under
balanced equation is
2ZnS(s)+3O2(g) -> 2Zn(s) + 2SO3(g)
In words:
When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc and 2 moles of sulphur trioxide gas.
Answer:
3.23 atm
Explanation:
Use the equation P₁V₁=P₂V₂. P₁ and V₁ are initial pressure and volume. P₂ and V₂ are final pressure and volume. Solve for P₂.
(1.88 L)(3.81 atm) = (2.22 L)(P₂)
7.1628 L*atm = (2.22 L)(P₂)
P₂ = 3.226 atm
