Pressure is the force per unit area pounded onto the surface of a container of a gas or liquid. It's interesting to notice that the units of pressure (force/area) are the same as the units of energy density (energy/volume). This gives rise to the interesting result that the pressure at the centers of stars that we think should be sustaining the star against collapse actually attracts more pressure, at high enough pressures, and contributes to collapse

As a result of the reaction of 109.5 grams of a solution of hydrochloric acid with an excess of zinc, a gas with a volume of 3.36 litres Was released. Calculate the mass fraction of hydrochloric acid in the original solution

Answers

Explanation:

Volume of gas produced = 3.36 L

as molar volume of gas at STP is 22.4 L

so

no of moles of H2 = 3.36 ÷ 22.4 = 0.15 mole

from balanced reaction equation

Zn + 2HCl = ZnCl2 + H2

Ratio of no of moles between H2 : HCl is 1:2

as H2 moles = 0.15 mole

so

HCl moles reacted = 0.15 × 2 = 0.3 mole

as HCl molar mass = 1 + 35.5 = 36.5 g/mole

so Mass of 0.3 mole of HCl = 0.3 × 36.5 = 10.85 gram

fraction of HCl in Solution

= 10.85 ÷ 109.5 = 0.1

0.1 ×100 so HCl is 10% of solution mass

Ionic or covalent



C Cl




Formula ____________ Ionic or covalent



Mg Cl




Formula _____________

Answers

C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

What is meant by chemical bonding?

The formation of a chemical bond between two or more atoms, ions or molecules to form a chemical compound is known as chemical bonding. The chemical bonding makes sure the atoms are together in the resulting compound.

Chemical bonding is made possible by an attractive force resulting from the overall loss of energy in the resultant molecule compared to its constituents.

Chemical compounds depend on chemical bonding for their stability. There are various kinds of chemical bonds formed. Covalent bonds and ionic bonds are 2 of the most commonly known chemical bonds.

Covalent bonds are formed by the sharing of electrons and an ionic bond is formed by the electrostatic force of attraction between the atoms.

Therefore, in the given examples, C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

The bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl  and  Mg-Cl ionic bond.

What is  polar covalent and ionic bond?

Polar covalent bonds are created between two non-metal atoms or molecules  that do consist of different  electronegativity. and the electronegativity difference that is not equal to zero and the shared pair of electrons forming a bond between will always be towards the high electronegative atom.

An ionic bond the  complete sharing or the  electron transfer. Ionic bonds basically form or created when the difference in the electronegativity of the two atoms is great or more as compare to   covalent bonds form when the electronegativity is same.

Therefore,  bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl  and  Mg-Cl ionic bond.

A hot lump of 30.5 g of iron at an initial temperature of 52.7 °C is placed in 50.0 mL H2O initially at 25.0 °C and allowed to reach thermal equilibrium. What is the final temperature of the iron and water, given that the specific heat of iron is 0.449 J/(g·°C)? Assume no heat is lost to surroundings.
final= _______ degrees Celsius

Answers

Answer:

26.7°C

Explanation:

Using the formula; Q = m × c × ΔT

Where; Q = amount of heat

m = mass

c = specific heat

ΔT = change in temperature

In this question involving iron placed into water, the Qwater = Qiron

For water; m= 50g, c = 4.18 J/g°C, Initial temp= 25°C, final temp=?

For iron; m = 30.5g, c = 0.449J/g°C, Initial temp= 52.7°C, final temp=?

Qwater = -(Qiron)

m × c × ΔT (water) =- {m × c × ΔT (iron)}

50 × 4.18 × (T - 25) = - {30.5 × 0.449 × (T - 52.7)}

209 (T - 25) = - {13.6945 (T - 52.7)}

209T - 5225 = -13.6945T + 721.7

209T + 13.6945T = 5225 + 721.7

222.6945T = 5946.7

T = 5946.7/222.6945

T = 26.7

Hence, the final temperature of water and iron is 26.7°C

to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.

Also what percentage of the heat is used to raise the temperature of the water?

Answers

Answer:

Q must be supplied = 119523.3~J

Explanation:

The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released  

Q in = Q out  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

So from the question :

Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)

which cells carry nutrients from food to the rest of the cells in the body?​

Answers

Answer: The circulatory system.

Explanation: The circulatory system, which is part of the "cardiovascular" system, is one of the eleven organ systems of the human body. Its main function is to transport nutrients to cells and wastes from cells (Figure 3.4. 1). This system consists of the heart, blood, and blood vessels.

The blood cells carry nutrients from food to the rest of the cells in the body.

What is the circulatory system?

The human circulatory system moves important nutrients and minerals throughout the body and metabolic waste products out from the body. The human circulatory system contains blood, blood vessels, heart, and lymph.

The human circulatory system provides essential nutrients, minerals, oxygen, and hormones to different parts of the body and is responsible for collecting toxins from the cells and tissues to be purified or eliminated from the body.

The human circulatory system contains a wide network of blood vessels. These constitute arteries, veins, and capillaries. The primary function of blood vessels is to transport nutrients and oxygenated blood to all parts of the body.

The Circulatory system helps in sustaining all the organ systems and transports blood, nutrients, oxygen, and hormones throughout the body. It secures cells from pathogens and acts as an interface for cell to cell interaction.

Answer:

Option D. 4.85×10¯¹⁹ J

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 7.31×10¹⁴ Hz.

Energy (E) =?

The energy of the photon of violet light can be obtained by using the following formula

E = hf

Where:

E is the energy.

h is the Planck's constant

F is the frequency.

Frequency (f) = 7.31×10¹⁴ Hz.

Planck's constant (h) = 6.63×10¯³⁴ Js

Energy (E) =..?

E = hf

E = 6.63×10¯³⁴ × 7.31×10¹⁴ Hz.

Which of the following would be true when iodine gains valence electrons?
A. it would form a cation with a -1 charge.
B. it would form a cation with a +1 charge.
C. it would form a anion with a -1 charge.
D. it would form a anion with a +1 charge.

Answers

Answer:

C. it would form a anion with a -1 charge.

Explanation:

The elements of group 17 are called halogens.

These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature.  Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while iodine is solid.

They require only one electron to complete the octet and get stable. Thus they form anion with charge -1 when they gain electron.

l + e⁻  → I⁻

They form ionic compound with alkali and alkaline earth metal such as sodium chloride (NaCl), Barium iodide (BaI₂) etc.

Properties of Iodine:

1. it is present in solid form.

2. it is crystalline in nature.

3. it is very corrosive and has pungent odor.

4. it can not react with oxygen and nitrogen.
