<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>TRIPLE POINT:</h2>

Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.

<h2>_____________________________________</h2><h2>WATER:</h2>

Water has a Melting point or Freezing Point (MP or FP) of $0^0$ C or 273K and Boiling point (BP) $100^{0}$ C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is $0.01^{0}$ C or 273.16K.

Answer: 5 days

Explanation:

1,000,000/2 = 500,000 *do this because of the 2 numbers every second

500,000/60= 8,333.33 *do this to get minutes

8,333.33/60= 138.88 *do this to get hours

138.88/24= 5.7866 *do this to get days

5 days 7 hours 8 minutes 6 seconds

What will happen if you put an object that has a density of 1.1 g/ml into a beaker of water?

Rainbow [258]

It will sink because water has a density of 1. and 1.1 is greater than 1 which means that the object is denser than the water so it will cause it to sink

Calculate normality and tire of KOH solution , if CN H2 C2 O4 solution , that is nessesary for titration is 0.1050 mol/1 and the

kozerog [31]

Answer:

Normality of KOH = 0.1062 N

<em>Note: The given question is not clearly stated. A related question below is answered and explained;</em>

<em> What is the NORMALITY of a solution of KOH if 45.18 mL are required to neutralize 0.3g of pure oxalic acid H2C2O4 . 2H2O?</em>

Explanation:

Equation of the reaction: 2KOH + H₂C₂O₄.2H₂O --> K₂C₂O₄ + 4H₂O

molar mass 0f KOH = 56 g/mol; molar mass of H₂C₂O₄.2H₂O = 126 g/mol

Number of moles of in 0.3 g of H₂C₂O₄.2H₂O = mass/molar mass

number of moles = 0.3 g / 126 g/mol = 0.0024 moles

From the equation of reaction, 2 moles of KOH are required to neutralize 1 mole of H₂C₂O₄.2H₂O

Number of moles of KOH required to neutralize 0.0024 moles of H₂C₂O₄.2H₂O = 2 * 0.0024 = 0.0048 moles

Molar concentration of 45.18 mL solution of KOH containing 0.0048 moles of KOH = number of moles/volume (L)

molarity of KOH solution = (0.0048/45.18 mL) * (1000 mL/1 L) = 0.1062 mol/L

Normality = n * molarity

where is the number of moles of OH⁻ ions produces from mole of KOH = 1

Normality of KOH = 1 * 0.1062

Normality of KOH = 0.1062 N
