A 10.04-g block of solid tin at 14.77 °C is immersed in a 24.11-g pool of liquid ethylene glycol with a temperature of 63.52 °C. When thermal equilibrium is reached, what is the temperature of the tin and ethylene glycol? Specific heat capacities: tin = 0.213 J/g °C; ethylene glycol = 2.36 J/g °C

Answers

Answer:

61.75 °C

Explanation:

According to the law of conservation of energy,

Qtin = - (Qliquid)

(m×c×∆T)tin = -(m×c×∆T) ethylene glycol

Where; m = mass

c = specific heat capacity

∆T = change in temperature

According to the information given in this question;

For tin: m= 10.04g, c= 0.213 J/g °C, initial temperature= 14.77 °C, final temperature=?

For ethylene glycol: m= 24.11g, c= 2.36 J/g °C, initial temperature= 63.52 °C, final temperature=?

Hence; (m×c×∆T)tin = -(m×c×∆T) ethylene glycol

10.04 × 0.213 × (T - 14.77) = - {24.11 × 2.36 × (T - 63.52)}

2.139 (T - 14.77) = - {56.899 (T - 63.52)}

2.139T - 31.59 = -56.899T + 3614.225

2.139T + 56.899T = 31.59 + 3614.225

59.038T = 3645.815

T = 3645.815/59.038

T = 61.75 °C

The final temperature of tin and ethylene glycol is 61.75 °C

A large marble is dropped in a graduated cylinder with 45 mL of water in it. The water level increased to 61 mL. What is the volume of the marble?​

Answers

Answer:

Volume of the marble is 16 ml.

Initial volume present in graduated cylinder=45 ml.

Final volume in graduated cylinder after marble is dropped=61 ml.

Volume of water displaced=volume displaced by marble.

Volume displaced by marble=final volume in cylinder-initial volume in cylinder

Volume displaced=61ml-45ml=16ml

So volume of marble=16ml.

Answer:

16mL

NA = 6.02 × 10* ( * = 23)

[tex]4 \times 5 \times 6.02 \times {10}^{23} = 20 \times 6.02 \times {10}^{23} = 120.4 \times {10}^{23}atom [/tex]

Answer:

2.408 x 10^24

GREETINGS!

One mole of a substance is equal to 6.02 × 10²³ units of that substance. The number 6.022 × 10²³ is known as Avogadro's number.

so if one mole of molecule is equal to that number so,

                              for 4 moles of [tex]HNO_{3}[/tex]= 4 x ([tex]6.02x10^{23}[/tex])

so answer is,

How did Thomson's experiment change Dalton's atomic model?
A. Thomson discovered that atoms changed properties when put in

B. Thomson discovered that atoms did not rearrange when forming
compounds.
C. Thomson discovered that atoms of one kind of element could
have different masses.
D. Thomson discovered that the atom contained smaller particles
called electrons.

Answers

Answer:

D. thomson discovered that the atom contains smaller particles called electrons

Thomson discovered that the atom contained smaller particles called electrons. The correct option is D.

What is Dalton's atomic model?

Dalton proposed that all matter is composed of tiny indivisible particles known as atoms, which he envisioned as "solid, massy, hard, impenetrable, movable particle(s)."

Thomson's experiment altered Dalton's atomic model by revealing the existence of smaller particles known as electrons within the atom.

The first part of his theory states that all matter is made up of indivisible atoms. According to the second part of the theory, all atoms of a given element have the same mass and properties.

One of Dalton's most important contributions is that it does not violate several fundamental laws of chemical combination, including the law of definite proportions, the law of multiple proportions, and the law of conservation of mass.

Thus, the correct option is D.

Answer:

12) In the ball and stick model, an orange ball representing the phosphorus atom and three green balls representing chlorine atoms are connected by means of sticks that are coloured halfway green and orange respectively to represent the shared electrons between phosphorus and chlorine with the chlorine atoms forming the base of a triangular pyramid while the phosphorus atom forms the top of the pyramid.

13) The scientist will have 6 grams of product as before but will have two grams of unreacted copper atoms because the mass ratio of copper to sulfur in this reaction is 2:1

Explanation:

12) Phosphorus trichloride has a trigonal pyramidal structure and is composed of three atoms of chlorine and one atom of phosphorus.

In the ball and stick model, an orange ball representing the phosphorus atom and three green balls representing chlorine atoms are connected by means of sticks that are coloured halfway green and orange respectively to represent the shared electrons between phosphorus and chlorine with the chlorine atoms forming the base of a triangular pyramid while the phosphorus atom forms the top of the pyramid.

13) The reaction between copper and sulfur to form copper sulfide is shown in the equation below:

Cu + S ---> CuS

1 mole of copper reacts with 1 mole of sulfur to produce 1 mole of copper sulfide

molar mass of copper = 64 g/mol; molar mass of sulfur = 32 g/mol, molar mass of copper sulfide = 96 g/mol

mass ratio of copper to sulfur = 63 g/ 34 g = 2

This means that 2 grams of copper will react with 1 g of sulfur to produce 3 grams of product. similarly, 4 g of copper will react with 2 g of sulfur to produce 6 grams of product.

Therefore 6 g of of copper will react with 3 g of sulfur. However, since the amount of sulfur available for reaction is 2 g only, 2 g of copper will be left unreacted after 4 g has reacted completely with 2 g of sulfur to produce 6 g of copper sulfide.

Write the chemical symbols for three different atoms or atomic cations with 26 electrons.

Answers

A neutral iron atom (Fe)

Mn-1 (a manganese that has gained one electron)

Co+1 (a cobalt that has lost on electrons)

All three of these atoms/ions are isoelectronic, meaning that they all have the same number of electrons!

The chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, [tex]Co^+[/tex], [tex]Ni^{2+}[/tex]

Explanation:

The atomic number of an atom is equal to the number of protonsAn atom is neutral, it has an equal number of electrons and protons.Element with atomic number 26 is Iron, Fe.A neutral atom of iron has an equal number of protons and electrons.Cobalt has an atomic number of 27.A neutral atom of cobalt has an equal number of protons and electrons.Cobalt has 27 electrons and by losing one electron it will form a cobalt (I) ion with 26 electrons.The cobalt (I) ion has 26 electrons, [tex]Co^+[/tex].Nickel has an atomic number of 28.A neutral atom of nickel has an equal number of protons and electrons.Nickel has 28 electrons and by losing two electrons it will form a nickel(II) ion with 26 electrons.The nickel (II) ion has 26 electrons,[tex]Ni^{2+}[/tex].

So, from this, we can write chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, [tex]Co^+[/tex], [tex]Ni^{2+}[/tex].

equatinal by elimination melha
8n-3y = 18 and5x+6y=27

Answers

Answer:

x = 3 and y= 2

Explanation:

Given equations:

           8x - 3y  = 18  - ---- (I)

           5x + 6y = 27 -------(II)

Solve this problem by elimination;

  In the elimination method, we simply find a common term that can make one of the variables in the two equation the same. Then we either add or subtract to remove the variable.

 Mulitply equation (i) by 5 to give equation III

 Mulitply equation (II) by 8 to give equation IV

     5(8x - 3y) = 5(18) ------- III

     8(5x + 6y) = 8(27) ------- IV

   40x - 15y = 90------- III

   40x + 48y = 216  ------- IV

Subtract  equation III and IV;

        -15y - 48y = 90 - 216

         - 63y = -126

                y = 2

Solve for x;

      40x - 15y = 90;

       40x - 15(2) = 90

         40x - 30 = 90

           40x = 90 + 30

              40x = 120

                 x = 3
