In a coffee-cup calorimeter, 1.55 g KOH is added to 125 ml of 0.80 M HCl. The following reaction occurs. KOH(s) + HCl(aq) → H2O(

l) + KCl(aq) Due to the reaction, the temperature of the solution changes from 32.3°C to 38.2°C. Given that the density of the HCl solution is 1.00 g/ml, and the specific heat of the final solution is 4.18 J/g·K, calculate the enthalpy change for this reaction in kJ/mol KOH.

- Nitinol is an alloy of *
Aleks04 [339]

Answer:

Nickel and Titanium

Explanation:

Nitinol is an alloy of Nickel and Titanium. It posesses two properties such that,

  • The shape memory effect
  • Super elasticity

Shape memory is the ability of nitinol to undergo deformation at one temperature, stay in its deformed shape when the external force is removed.

Superelasticity is the ability for the metal to undergo large deformations and immediately return to its undeformed shape upon removal of the external load.

Hence, the correct option is (b) "Nickel and Titanium".

A compound with a molar mass of 102.133 g/mol contains an element with a subscript of 5 . the element is 58.80 g per 100.0 g com
VLD [36.1K]

Answer:

12.0108408

Explanation:

Denote the element with a letter like say X. Since it has a subscript of 5, then, X5.

Molecular mass=102.133g/mol.

% of X in compound =58.8/100

=0.588

Mass of X in the compound = 0.588*102.133 ( the % of X in compound * molar mass of compound)

= 60.054204

X5=60.054204

Then element X has a mass of 60.054204/5=12.0108408
