Chemistry

Answer: Option (A) is the correct answer.

Explanation:

A temperature at which both solid and liquid state of water are present in equilibrium is known as melting point and the temperature remains constant during this transition of phase.

As it is shown in the graph that temperature at point A is zero degree celsius that is, the temperature at which water freezes completely. And, point B shows that solid and liquid phase are in  equilibrium. This means that the temperature at point B is also zero degree celsius.

Hence, we can conclude that temperature at point B is 0^{o}C, because it is the melting point of ice.

Answer:

A) 0 °C, because it is the melting point of ice.

Explanation:

  • Point B is the temperature at which the water is converted from ice (solid phase) to liquid water (liquid phase), which is the melting transition of water.

Melting point of the water is at 0.0°C.

<em>So, the right choice is: A) 0 °C, because it is the melting point of ice. </em>

If 3 g of element C combine with 8 g of element D to form compound CD, how many grams of D are needed to form compound CD2?
bija089 [108]
<span>For the answer to the question above,
If 3g of element combines with 8g of D to form CD it means
1 mole of C = 3g
1 mole of D = 8g
hence it forms CD.
So to form CD2 you need 16g of element D

Absolute zero is what temperature on the fahrenheit scale?
vampirchik [111]

Answer:

  • Absolute zero is - 459.67 °F

Explanation:

<u>1) Convert absolute zero to celsius:</u>

  • 0 K = - 273.15°C ( this is per definition of the scale)

<u>2) Convert - 273.15°C to Fahrenheit:</u>

  • T (°F) = T (°C) × 1.8 + 32 (this is the conversion equation=

  • T (°F) = - 273.15 × 1.8 + 32 = - 459.67 °F ← answer
