Answer:

3.44× 10²³ atoms

8.73× 10²⁵ molecules

37.64 × 10²³ molecules

0.014 × 10²³ molecules

Explanation:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

a) 0.572 moles of Al:

1 mole = 6.022 × 10²³ atoms

0.572 mol  ×  6.022 × 10²³ atoms / 1 mol

3.44× 10²³ atoms

b) 1.45× 10² moles of SO₂:

1 mole = 6.022 × 10²³ molecules

1.45 mol × 10² ×  6.022 × 10²³ molecules / 1 mol

8.73× 10²⁵ molecules

c) 6.25 moles of Ca(OH)₂

1 mole = 6.022 × 10²³ molecules

6.25 mol  ×  6.022 × 10²³ molecules / 1 mol

37.64 × 10²³ molecules

d) 0.0024 moles of CO₂

1 mole = 6.022 × 10²³ molecules

Answer:

Induction

Explanation:

When a body is brought in contact with another, electrons are rearranged by contact.

When a body is rubbed against one another, charging by friction occurs.

The process whereby electrons are rearranged without direct contact with one another is called induction.

By induction electrons can get charged without them having to be in contact with one another.

Answer:

Freshwater is such a limited resource because there is such a little amount of freshwater found on Earth. About 77% of fresh water on Earth is frozen in glaciers and polar ice caps. Because of this, there is very little fresh water available for humans to use.

Explanation: Hope this helps.

Freshwater is a scarce resource, making up just around 3% of the total amount of water on Earth. Although freshwater is regarded as a renewable resource, certain areas utilize more freshwater than can be replaced by natural processes.

There is a very small amount of fresh water on Earth, making it a scarce resource. The polar ice caps and glaciers contain around 77% of the fresh water on Earth. This results in a relatively limited supply of fresh water for human use.

Since freshwater only accounts for around 3% of the total amount of water on Earth, it is a limited resource.

Answer:

D. Electrodes

Explanation:

A redox reaction is defined as the reaction in which both oxidation and reduction reactions take place and electrons are transferred from oxidized substance to the substance that is being reduced.

An electrochemical cell is consist of electrodes (anode and cathode), electrolyte solution, salt bridge, and conducing wire. An electrochemical cell undergoes redox reaction that produces an electric current due to the movement of ions through electrodes. Electrodes are the source of ions, as anode electrode undergoes oxidation reaction and releases electrons or ions and cathode, gains electrons through reduction reaction.

Hence, the correct answer is "D. Electrodes".

Answer:

Lithium is an alkali metal. The symbol for lithium element is ‘Li’. It belongs to group 1 of periodic table. Its electronic configuration is 1s2 2s1. It has one valence electron. So it loses one electron to attain stable configuration. Hence the symbol for lithium ion is ‘Li+’.

Explanation:

ithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in compounds, such as pegmatitic minerals, which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines. Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride.

Answer: the water bottle

Explanation:

yuh

One of the basic states of matter, described as having a distinct shape, size, and organized structure, is solid. The constituent particles of solids have fixed positions and oscillate around their mean positions. Solids also have distinct borders. Here the solid is a water bottle.

The atoms and molecules in a solid are so tightly bound together that they vibrate in situ rather than moving. Liquids have a fixed volume but can flow to change their shape. Atoms and molecules are only weakly bound together in liquids.

In the water bottle, a solid is a water bottle and water is a liquid. Solids' molecules continue to be tightly packed. Solids' molecules don't move about freely in all directions; instead, they stay stationary.

Given

6.00 L water with 6.00 L of  ethylene glycol(ρ=1.1132 g/cm³= 1.1132 kg/L)

Required

The molality

Solution

molality = mol of solute/ 1 kg solvent

mol of solute = mol of ethylene glycol

= volume x density

= 6 L x 1.1132 kg/L

= 6.6792 kg

= 6679.2 g

[tex]\tt =\dfrac{107.608}{6}=17.93~m[/tex]

Answer:

2.47 L

Explanation:

The first thing we do is to write the balanced equation, which is.

CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g)

Now, using ideal gas equation, we see that

PV = nRT

moles of methane

where P is the pressure, 1.65 atm

V is the volume, 2.8 L

R is the ideal gas constant, 0.0821

T is the temperature in Kelvin, 25 + 273 = 298 K

n = PV/RT

n of methane = 1.65 * 2.8 / 0.0821 * 298

n of methane = 4.62 / 24.47

n of methane = 0.189 mole

moles of O2:

PV = nRT

where P is the pressure 1.25 atm

V is the volume, 35 L

R is the ideal gas constant, 0.0821 L

T is the temperature, 31 + 273 = 304 K

n of O2 = 1.25 * 35 / 0.0821 * 304

n of O2 = 43.75 / 24.96

n of O2 = 1.75 mol

from the equation, the molar ratio between O2 and CH4 is 2:1, so therefore

no of moles of O2 = 2 * .0189 moles of methane = 0.378 mole

when 1 mole of CH4 --> 1 mole of CO2

1 mol of CO2 --> 22.4 L CO2

volume of CO2 at STP = [(0.189 moles of CH4 /1) * (1 mol of CO2)] / [(1 mole CH4) * (22.4L CO2)/(1 mol of CO2)] = 4.23 L

Next, we use the formula

P1V1 /T1 = P2V2/T2

where

P1 = 1 atm

V1 = 4.23 L

T1 = 273

P2 = 2.5 atm

T2 = 125 + 273 = 398 K, making V2 subject of formula, we have

V2 = P1V1T2 / T1P2

V2 = 1 atm * 4.23 L * 398 / 273 * 2.5 atm

V2 = 1683.54 / 682.5

V2 = 2.47 L
