Answer:

Density =mass/Volume

First of all let's find the mass

= 2.5 ×102kg

= 225kg

Then the volume

=4.1 × 103 m3

=422.3m3

225kg /422.3m3

=0.53279659

The density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3  will be 6.03  kg/m³ .

Density is defined as the ratio of mass of the object to the volume of the object. Different substances have different densities.

The mathematical expression for density is as follows:

Density=Mass/Volume

The mass of a substance is expressed in kilograms and the volume is expressed in liter.

Thus, the unit of density is kg L⁻¹.

The density of a substance does not depend on the amount of the matter.

Thus, density is an intensive property.

To calculate  the density -:

Given,

Mass= 2.5 ×102 kg=2550 kg

Volume=4.1 × 103 m³=422.3m³

Density=mass/volume

Density=2550/422.3

Density=6.03kg/m³

Hence, 6.03kg/m³ is the  density of a piece of metal .

Answer:

I don't think endothermic reactions have anything to do with temperature. Instead they focus on the direction of the transfer of energy whether it is inside a body or to the surroundings.

The Concentration of NaOH solution when NaOH solution was titrated with 25cm3 of a 0.75mol/dm3 HNO3 is 26.4 g/dm3.

Given,

Volume of HNO3 is 25cm³ = 0.025 dm³

Amount of solute in mol = concentration in mol/dm3 × volume in dm3

Amount of HNO3 = 0.75 × 0.025 = 0.018 mol

The balanced equation is: NaOH(aq) + HNO3(aq) → NaNO3(aq) + H2O(l)

So the mole ratio NaOH:HNO3 is 1:1

Therefore 0.018 mol of NaOH reacts with 0.018 mol of HNO3.

Volume of sodium hydroxide solution 27.20cm³ =

0.027 dm³.

Concentration = 0.018 / 0.027 = 0.66 mol/ dm³

Relative formula mass of NaOH= 40

Mass = relative formula mass × amount

Mass of HCl = 40 × 0.66

= 26.4

So concentration = 26.4 g/dm3

Therefore, concentration of NaOH is 26.4 g/dm3

When, molar heat of solution of potassium chlorate is +41.4 kJ/mol. The temperature of the water will decreases when, potassium chlorate is dissolved into it.

When potassium chlorate is dissolved in water, the process is typically exothermic, meaning it releases heat. In this case, since the molar heat of solution of potassium chlorate is specified as +41.4 kJ/mol, it indicates that the dissolution process is endothermic, and 41.4 kJ of heat is absorbed per mole of potassium chlorate dissolved.

Therefore, when potassium chlorate is dissolved in water, the temperature of the water will decrease. The heat energy is transferred from the water to the potassium chlorate, resulting in a decrease in the temperature of the water.

(a) ==> O²-

(b) ==> Al³+

(c) ==> Ti²+

(d) ==> I-

The correct option is (b) the solution is neutral. The solution is prepared by adding 0.10 mol of \(LiNO_3\) to 1.00 L of water is a neutral solution.

Lithium nitrate (\(LiNO_3\)) is an ionic compound that dissociates into ions when dissolved in water:

\(LiNO_3\) → \(Li^+\) (aq) + \(NO_3^-\)(aq)

\(Li^+\) and  \(NO_3^-\) are both spectator ions, which means they don't participate in acid-base reactions. Therefore, the acidity of the solution will be determined by the reaction between water and the remaining ions.

Since neither \(Li^+\) nor \(NO_3^-\) reacts with water, the solution will be neutral. It is important to note that the \(K_a\) and \(K_b\) values of the species in solution do not need to be known in order to predict the acidity of the solution, since \(Li^+\) and \(NO_3^-\) are both spectator ions and do not participate in acid-base reactions.

Therefore, the correct option is (b) the solution is neutral.

There 88.94 grams would be grams of aluminum chloride are produced when aluminum reacts with 18.0 grams of hydrochloric acid to produce aluminum chloride and hydrogen gas.

To calculate aluminum chloride that are produce first we should write the balance reaction

2Al + 6HCl → 2AlCl₃ + 3H₂,

Then we can calculate the moles of aluminum

Moles aluminum = mass/ mass molar

Moles aluminum = 18 grams / 27 grams / moles

Moles aluminum = 0.667 moles

Form the reaction, it is clear that 2.0 moles of Al react with 6.0 mole of HCl to produce 2.0 moles of AlCl₃ and 3.0 mole of H₂.

using unitary method we can calculate the moles of Aluminum chloride

moles AlCl₃ = 2/2 x mole Al

Moles AlCl₃ = 2/2 x 0.667 moles =0.667 moles

Mass AlCl₃ = moles x mass molar

Mass AlCl₃ = 0.667 moles x 133.34 g/mol

Mass AlCl₃ = 88.94 grams

Explanation:

Half-life is the amount of time that is used by the given amount of substance or element to make it half of the initial amount of a particular radioactive substance.

Equation for alpha decay for radon

\(^222_{86}Rn\Rightarrow^{218}_{84}Po  \)

we need to calculate the left amount of radon after given time

using formula half life

\(N(t)=N_{0}e^{-\lambda t}\)

\(\lambda =\dfrac{0.693}{3.82}\)

\(\lambda=0.1814\)

\(N(3.82)=150\times e^{-0.1814\times3.82}\)

\(N(3.82)=75.0\ g\)

Thus, the left amount of radon is - 75 grams.

The energy change that occurs when ice is added to the warm drink when a glass of water left in the sun becomes warm and Estella adds ice to the water to make it cool is that the water loses heat to the ice, causing the ice to melt.

The correct option is A.

Ice melts in warm water due to the transfer of heat energy from the water to the ice.

Heat flows from a warmer object to a cooler object until they reach thermal equilibrium, meaning they are at the same temperature. In the case of ice melting in warm water, the water is warmer than the ice, so heat flows from the water to the ice, causing the ice to melt.
