How much heat is required to change 56.0 g of ice (H2O) at 263 K to vapor (steam) at 400 K?
Leona [35]

Heat required = 173 kJ

<h3>Further explanation</h3>

Given

56.0 g of ice

Temperatur at 263 K(-10 C) to 400 K(127 C)

Required

Heat needed

Solution

1. raise the temperature(-10 C to 0 C)⇒c ice=2.09 J/g C

\tt Q=56\times 2.09\times (0-(-10)=1170.4~J

2. phase change (ice to water)⇒Heat of fusion water=334 J/g

\tt Q=56\times 334=18704~J

3. raise the temperature(0 C to 100 C)⇒c water= 4.18 J/g C

\tt Q=56\times 4.18\times (100-0)=23408~J

4. phase change(water to vapor)⇒heat of vaporization water=2260 J/g

\tt Q=56\times 2260=126560~J

5. raise the temperature(100 C to 127 C)⇒c vapor=2.09 J/g C

\tt Q=56\times 2.09\times (127-100)=3160.08~J

Total heat :

1170.4+18704+23408+126560+3160.08=173,002.48 J=173 kJ

A 15.00-ml sample of a naoh solution of unknown concentration requires 17.88 ml of a 0.1053 m h2so4 solution to reach the equiva
Sergeu [11.5K]

Answer:

  • <u>0.1255 M</u>

Explanation:

<u>1) Data:</u>

Base: NaOH

Vb = 15.00 ml = 15.00 / 1,000 liter

Mb = ?

Acid: H₂SO₄

Va = 17.88 ml = 17.88 / 1,000 liter

Ma = 0.1053

<u>2) Chemical reaction:</u>

The <em>titration</em> is an acid-base (neutralization) reaction to yield a salt and water:

  • Acid + Base → Salt + Water

  • H₂SO₄ (aq) + NaOH(aq) → Na₂SO₄ (aq) + H₂O (l)

<u>3) Balanced chemical equation:</u>

  • H₂SO₄ (aq) + 2 NaOH(aq) → Na₂SO₄ (aq) + 2H₂O (l)

Placing coefficient 2 in front of NaOH and H₂O balances the equation

<u>4) Stoichiometric mole ratio:</u>

The coefficients of the balanced chemical equation show that 1 mole of H₂SO₄ react with 2 moles of NaOH. Hence, the mole ratio is:

  • 1 mole H₂SO₄ : 2 mole NaOH

<u>5) Calculations:</u>

a) Molarity formula: M = n / V (in liter)

   ⇒ n = M × V

b) Nunber of moles of acid:

  • nₐ = Ma × Va = 0.1053 (17.88 / 1,000)

c) Number of moles of base, nb:

  • nb = Mb × Vb = Mb × (15.00 / 1,000)

d) At equivalence point number of moles of acid = number of moles of base

  • nₐ = nb

  • 0.1053 × (17.88 / 1,000) =  Mb × (15.00 / 1,000)

  • Mb = 0.1053 × 17.88  / 15.00 = 0.1255 mole/liter = 0.1255 M

Determine the volume of a substance that has a density of 1.84 g/ml and a mass of 12 grams
vazorg [7]
Hey there!:

density = mass / volume

1.84 g/mL =  12 g / V

V =  12 / 1.84

V = 6.521 mL

hope this helps!

How does an electron reach an excited state
quester [9]

When an electron quickly occupies an strength state increased than its ground state, it is in an excited state. An electron can end up excited if it is given greater energy, such as if it absorbs a photon, or packet of light, or collides with a close by atom or particle.
