A 120g block of pinewood has a volume of 300cm3. Would this block float on water? (HINT: Water has a density of 1g/cm3). a. No, because the block is denser than water.

Also here's a free meme

The density of a material represents the denseness of that material in a specific given area. If an object has a density less than water then it will float on water otherwise it will sink. Here the wood will float on water.

The density of a material denotes the measurement which compares the amount of matter an object has to its volume. An object with more matter in a certain volume has a high density. It is defined as the mass per unit volume.

The density is usually represented by symbol ρ or by the letter D. The formula used to calculate the density is:

Density = Mass / Volume

D = 100 / 300 = 0.33 g/cm³

Here the density of water is 1.0 g/cm³ which is greater than the density of  pine wood. So the pine wood will float on water.

The mass of sulfurous acid produced when 245g of sulfur dioxide is reacted with water is 313.8 g

From the question, we are to determine the mass of sulfurous acid produced

First, we will write the balaced chemical equation for the reaction

H₂O + SO₂ → H₂SO₃

This means 1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)

Now, we will determine the number of moles of sulfur dioxide present

Mass of sulfur dioxide present = 245 g

Molar mass of sulfur dioxide = 64.066 g/mol

Using the formula,

[tex]Number \ of \ moles = \frac{Mass}{Molar\ mass}[/tex]

Then,

Number of moles of SO₂ present = [tex]\frac{245}{64.066}[/tex]

Number of moles of SO₂ present = 3.824 moles

This is the number of moles of SO₂ present

From balanced chemical equation

1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)

Then,

Water (H₂O) will react with the 3.824 moles of sulfur dioxide (SO₂) to produce 3.824 moles of sulfurous acid (H₂SO₃)

∴ The number of moles of sulfurous acid produced is 3.824 moles

Now, for the mass of sulfurous acid produced

Molar mass of sulfurous acid = 82.07 g/mole

Using the formula,

Mass = Number of moles × Molar mass

Mass of sulfurous acid produced = 3.824 × 82.07

Mass of sulfurous acid produced = 313.8 g

Hence, the mass of sulfurous acid produced is 313.8 g

The color of the system will change between pink and blue depending on the concentration of species.

Equilibrium is attained in a reaction when the rate of forward reaction is equal to the rate of reverse reaction. Now consider the equilibrium;

The new volume of the gas in the balloon when the pressure is doubled is determined as 11.2 L.

The new volume of the balloon is determined by applying general gas equation as shown below

P₁V₁/T₁ = P₂V₂/T₂

Where;

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \\\\V_2 = \frac{P_1V_1T_2}{T_1P_2} \\\\V_2 = \frac{1 \times 22.4 \times 273}{273 \times 2} \\\\V_2 = 11.2 \ L[/tex]

The shorthand equation shows us in a glance what happens in the electrochemical reaction. For a lead storage battery, we have; PbSO4(s)/H2O//Pb (s) ,PbO2(s) /H2SO4

An electrochemical reaction is one in which electrical energy is produced from a chemical reaction. The equations in a lead storage battery are;

Anode: Pb (s) + HSO4- → PbSO4(s) + H+ + 2 e-

Cathode: PbO2(s) + HSO4- + 3 H+ + 2 e- → PbSO4(s) + 2 H2O

Overall: Pb (s) + PbO2(s) + 2 HSO4- + 2 H+ → 2 PbSO4(s) + 2 H2O

Hence, the shorthand notation of this reaction is;

PbSO4(s)/H2O//Pb (s) ,PbO2(s) /H2SO4

Mark the lime poor conducter of heat and electricity.

Yes why no ,Xenon is already has its secured place in modern periodic table.

Xenon is a non-reactive gas. It will not conduct and react normally. Thus it can be classified as a non-metal. Xenon is placed in the inert gas or noble gas group that is group 18.

Noble gases are inert gases in the 18th group of periodic table. Noble gases have completely filled orbitals and thus they no need other electrons.

Atoms participate in reaction when they are not stable because of the insufficient valence electrons. Noble gases such as argon, krypton, neon, xenon etc. have 8 valence electrons and thus are not reactive.

Metals are highly conductive and they are placed in the left side of periodic table. In periodic table, from left to right the metallic nature decreases and the other elements are called non-metals. Most of the non-metals are gases and very few such as silicon is metalloid.

Non-metals are insulators or poorly conduct electricity. Hence, xenon is a non-metal placed in the 18th group of periodic table.

Assuming an ebullioscopic constant of 0.512 °C/m for the water, If you add 30.0g of salt to 3.75kg of water, the boiling-point elevation will be 0.140 °C and the boiling-point of the solution will be 100.14 °C.

Boiling-point elevation describes the phenomenon that the boiling point of a liquid will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent.

We will use the definition of molality.

b = mass solute / molar mass solute × kg solvent

b = 30.0 g / (58.44 g/mol) × 3.75 kg = 0.137 m

We will use the following expression.

ΔT = Kb × m × i

ΔT = 0.512 °C/m × 0.137 m × 2 = 0.140 °C

where

The normal boiling-point for water is 100 °C. The boiling-point of the solution will be:

100 °C + 0.140 °C = 100.14 °C

Assuming an ebullioscopic constant of 0.512 °C/m for the water, If you add 30.0g of salt to 3.75kg of water, the boiling-point elevation will be 0.140 °C and the boiling-point of the solution will be 100.14 °C.

The fruit which has the greater mass is peach i.e. 150 grams.

Mass is a quantity which is used to define that what amount of substance will occupy any space or present in the given object.

We have given,

Weight of apples = 85,000 mg

Weight of peach = 0.15 kg

To compare the quantity first we have to convert both of these units in the same unit, and we know that:

In 1 kilogram = 1000 grams

And in 1 grams = 1000 milligrams

So, we convert both the units into grams as:

85,000 mg =  85,000 / 1000 = 85 grams

0.15 kg = 150 grams

So, the mass of peach is high.

Hence, peach has the greater mass.

Single replacement is a reaction in which one element reacts with another compund to form another compound and another element.

planation:

If the reaction is double displacement then two molecules will be displaced and if it is single displacement reaction then only one element displaces.

Displacement reactions are those reactions in which any element of the given reactant will be displaced by any another element.

If only one element from the reactant molecules will displace then it will be known as single displacement reaction. If two elements or atoms will be displaced from the reactant molecules then it will be known as double displacement reaction.

Hence if one element displaceed then called the single displacement reaction and if two elements displaces then called as the double displacement reaction.
