The property X is an extrinsic property.

The term extensive property refers to the type of property that depends on the amount of the substance present. We must recall that an intensive property does not in any way depend on the number or the amount of the substance present in the sample.

If we have a good look at the table that is being referred to here, we would see that the mass of the substance tends to increase as a certain un named property of the substance X is increasing. This implies that the property X is affected by the mass of the object which is the quantity of matter in the object. This gives us an idea that the property that we are referring to can not be an intrinsic  property since it varies with the mass of the substance that is under study as shown.

We can then conclude that the property X is an extrinsic property.

plays a role in the production of essentially all elements heavier than helium

releases large amounts of energy

Explanation:

Fusion reaction takes place when two or more small atomic nuclei come in close proximation for a longer time so the nuclear force pulling them together and form into heavier molecules than helium and releases a huge amount of energy by this process.

A great example of this fusion reaction is the sun where nuclear fusion takes place inside the core of the sun and result in a huge amount of release as it is an exothermic reaction.

Answer:  on Earth, a 5.0-kg object weighs 49 N; on the Moon, where g is 1.67m/s2 1.67 m/s 2 , the object weighs 8.4 N.

Explanation:

Answer:

The sun is 27.9 times heavier the moon is 16.5% of it on earth

Explanation:

On the moon, there is less gravity pulling on objects, so they weigh less. For example, a rock that weighs one pound while on Earth will weigh less than that if it is taken to the moon.

The volume of the NaOH used is calculated as 14 mL.

The term stoichiometry has to do with the calculation of the amount of substance in a reaction using mass - mole or mass - volume relationship.

Here;

Number of  moles of CaCO3 = 0.205 g/100.1 = 0.00205 moles

Number of  moles of HCl = 2.00 M * 7/1000 L = 0.014 moles

2 moles of HCl reacts with 1 mole of CaCO3

x moles of HCl reacts with 0.00205 moles of CaCO3

x = 0.00205 moles * 2/1 = 0.0041 moles

Hence HCl is the excess reactant

Amount of excess HCl =  0.014 moles -  0.0041 moles = 0.0099 moles

Concentration of excess HCl reacted = 0.0099 moles/125 * 10^-3 = 0.0792 M

Using;

CAVA/CBVB = NA/NB

CAVANB = CBVBNA

VB = CAVANB/CBNA

VB = 0.0792 M * 10 mL * 1/ 0.058 M

VB = 14 mL

0.297 kJ of heat is needed to raise the temperature of 10g of aluminum from 22 degrees Celsius to 55 degrees Celsius.

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

It is a measure of how much energy it takes to raise the temperature of a substance. It is the amount of heat necessary to raise one mass unit of that substance by one temperature unit.

It is given by the formula -

                                                  Q = mcΔT

where, Q = amount of heat

m = mass

c = specific heat

ΔT = Change in temperature

Given,

mass = 10g

c = 0.901J/g⁰C

Initial temperature (T₁) = 22⁰C

To name Type 2 ionic compounds such as AuCl₃, you need to use the Stock system or Roman numeral system to indicate the oxidation state of the cation. Some steps are; Identify the cation, Determine the charge, Write the name, and combine two names.

Here are the steps to name AuCl₃; Identify the cation and anion. In this case, the cation is Au³⁺ and the anion is Cl⁻.

Determine the charge on the cation by using the anion's charge and balancing the charges to zero. Since Cl⁻ has a charge of -1 and there are three Cl⁻ ions in the compound, the total negative charge is -3. Therefore, the Au³⁺ ion has a charge of +3.

Write the name of the cation first, followed by the name of the anion with an -ide ending. Since the cation is Au³⁺, we use the name "gold(III)" to indicate the oxidation state of +3. The anion is Cl⁻, so we add the -ide ending to get "chloride".

Combine the two names to get the compound's name: "gold(III) chloride".

Therefore, the name of the Type 2 ionic compound AuCl₃ is "gold(III) chloride".

Explanation:

To find the percent water in the hydrate, you need to

(2) calculate the percent composition

(Step 1)

Atomic Mass (Mg): 24.305 g/mol

Atomic Mass (S): 32.065 g/mol

Atomic Mass (O): 15.999 g/mol

Atomic Mass (H): 1.008 g/mol

Mass (MgSO₄): 24.305 g + 32.065 g + 4(15.999 g/mol) = 120.366 g

Mass (7H₂O): 14(1.008 g/mol) + 7(15.999 g/mol) = 126.105 g

Mass (MgSO₄·7H₂O): 120.366 g + 126.105 g = 246.471 g

The electrons move from left to right through the circle labeled "M" to reach the cathode, where reduction takes place.

If oxidation occurs on the left side of the fuel cell and reduction occurs on the right side, the movement of electrons can be described as follows: Electrons move from left to right through the circle labeled "M."

In a fuel cell, the process of oxidation takes place at the anode (labeled A) where the fuel is oxidized, releasing electrons. These electrons then flow through the external electrical circuit, represented by the wire connecting objects A and B. The electrons reach the cathode (also labeled A) on the right side of the cell, where reduction occurs.The circle labeled "M" represents the membrane or electrolyte in the fuel cell. This membrane allows the transport of ions but blocks the movement of electrons. As a result, electrons cannot flow directly through the electrolyte but must travel through the external circuit.

This movement of electrons through the external circuit is what generates an electric current that can be used to power electrical devices or systems.

Z = 1 - a/VRT

Explanation:

Note :

Compressibility Factor, Z = PV / RT

Vander waal forces at Lower pressure is represented by the expression :

V[P + a/V²] = RT

Aim is to move PV /RT =Z to one side of the equation.

Using change of subject :

opening the bracket :

PV + aV / V² = RT

PV + a/V = RT

Divide through by RT

PV/RT + a/VRT = RT/RT

PV/RT + a/VRT = 1

Recall:

PV /RT = Z

equation becomes :

Z + a/VRT = 1

Subtract a/VRT from both sides

Z + a/VRT - a/VRT = 1 - a/VRT
