Answer:
Explanation:
In calorimetry we apply the formula
heat lost = heat gained
m₁ x s₁ t ₁ = m₂ x s₂ t ₂
here t₁ and t₂ are change in temperature . suppose s₁ denotes specific heat of metal a nd s₂ denotes specific heat of water .
If s₁ is far less than s₂ , t₁ will be far more than t₂ , to balance the two sides
Hence change in temperature of metal pot will be more than change in temperature of water.
Final temperature will be far away from temperature of the metal pot.
Final temperature will be closer to temperature of water.
False, I'm assuming, due to their names. Continents are landmasses and maritime is always to do with the sea
Answer:
See the answer below
Explanation:
Beryllium forms an ion with 2 electrons in its outermost shell. Hence<u> the charge on the element is 2+</u>, that is, Be2+. In order for Be to form a stable bond with another element, <u>such an element must have a deficit of electrons in its outermost shell</u>. Beryllium will have to donate its 2 electrons to this element for its self-stability.
Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
