The heat of fusion for ice is 334 joules per gram. Adding 334 joules of heat to one gram of ice at STP will
yulyashka [42]

C) change to water at the same temperature

Explanation:

Adding 334Joules of heat to one gram of ice at STP will cause ice to change to water at the same temperature.

  • The heat of fusion is the amount of energy needed to melt a given mass of a solid
  • It is also conversely the amount of energy removed from a substance to freeze it.
  • The addition of this energy does not cause a decrease or increase in temperature.
  • Only a phase change occurs.

What is the graph that represents the relation between durability of titanium and temperature ?
matrenka [14]

The downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

<h3>Can titanium withstand temperatures?</h3>

Titanium alloys have high tensile strength to weight ratio, good toughness and an ability to bear extreme temperatures of more than 600 °Celsius. This shows that if temperature increase from more than 600 °Celsius, the strength of the titanium tends to decrease because it can not withstand to it so the graph comes to downward when the temperature exceeds to 600°C.

So we can conclude that the downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

The chemical equation for the formation of ammonia is unbalanced. 3H2(g) + N2(g) -----&gt; NH3(g) If three molecules of hydrogen
mestny [16]

Answer: 2 molecules of ammonia

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the formation of ammonia is:

3H_2(g)+N_2(g)\rightarrow 2NH_3

According to stoichiometry,

3 molecules of hydrogen combines with 1 molecule of nitrogen to give 2 molecules of ammonia.
