It would be C

2 kg x 1000 g/kg x 1mol/18.02 x 6.03 kj/mol = 669kj

When an irregularly shaped chunk of an unknown metal with a mass of 25.32 g was placed in a graduated cylinder containing 25.00
inn [45]

Answer: The density of the unknown metal is 7.86 g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of metal  = 25.32 g

Volume of metal = volume of water displaced = (28.22 - 25.00) ml = 3.22 ml

Putting in the values we get:

density=\frac{25.32g}{3.22ml}

Density=7.86g/ml

Thus the density of the unknown metal is 7.86 g/ml

Pls assist if you can.<br>Reasons why hydrogen was chosen as a standard reference to other elements
MrMuchimi

Answer:

See below  

Step-by-step explanation:

  • Hydrogen either reacts with or is formed by reactions with many other elements, so chemists could use it directly to determine their relative masses.
  • Hydrogen has the smallest atomic mass, so it was convenient to give H a relative atomic mass of 1 and assign those of other elements as multiples of this number.

The O = 16 scale became the standard in 1903 and carbon-12 was chosen in 1961.

Density decreases that's why ice floats on water because it's less dense than water.
