What is the graph that represents the relation between durability of titanium and temperature ?

1 answer:

8 0

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.

Explain the scientific meaning and use of the word "transformation".

sladkih [1.3K]

Transformation in chemistry is scientifically used to explain the process of changing one compound to another in a chemical reaction.

<h3>What is transformation?</h3>

The word "transformation" has a very special significance in chemistry. We know that in English, to transform would simply imply to change from one form to another. This is not quite far from its meaning in the parlance of chemistry.

The word transformation is normally applied in the area of chemical reactions especially as it has to do with reaction with in organic chemistry. It has to do with the change from one molecule to another and this is of great importance in the discussion of synthetic chemistry.

As such, the word transformation in chemistry is scientifically used to explain the process of changing one compound to another in a chemical reaction.

A calorimeter contains 251 g of water at 24.3 C.The temperature of the water decreases to 18.5 C when 12.5 g of potassium nitrat

vova2212 [387]

Answer:

Endothermic

Explanation:

The temperature of the water decreased.

The water lost heat.

The heat must have gone into getting the KNO₃ into solution.

So, the dissolving of KNO₃ in water is endothermic.

A 26.08 g mixture of zinc and sodium is reacted with a stoichiometric amount of sulfuric acid. The reaction mixture is then reac

Over [174]

Answer:

Molar percent of sodium in original mixture is 88,50%

Explanation:

The last reaction is:

BaCl₂ + Na₂SO₄ → BaSO₄ + 2 NaCl

The moles of BaCl₂ are:

0,132L × 3,80M = 0,502 moles of BaCl₂

As the amount of BaCl₂ is the maximum possible to produce BaSO₄, the moles of BaCl₂ must be the same than moles of Na₂SO₄.

0,502 moles of BaCl₂ ≡ 0,502 moles of Na₂SO₄

These moles of Na₂SO₄ comes from:

2 Na + H₂SO₄ → Na₂SO₄ + H₂

As the reaction is in stoichiometric amounts, moles of Na are twice the moles of Na₂SO₄

0,502 moles of Na₂SO₄ × $\frac{2molesNa}{1moleNa_{2}SO_{4}}$ × 22,99 g/mole = 23,08 g of Na

Molar percent of sodium in original mixture is:

$\frac{23,08g}{26,08g}*100$ = <em>88,50% </em>
