Based on the formula for calculating quantity of Heat, the student requires the mass, temperature change and the specific heat capacity of the reaction mixture.

The enthalpy change of a reaction is the amount of heat evolved or absorbed when reactant molecules react to form products.

In the use of a calorimetry to determine the enthalpy of a reaction, the law of conservation of energy is applied.

The quantity of Heat is calculated using the formula below:

Therefore, in addition to the masses of the solutions and the temperature change, the student requires the specific heat capacity of the reaction mixture.

The phrase that defines bond energy is the energy required to break a chemical bond.

Bond energy is amount of energy needed to break the atoms involved in a chemical bond into free atoms.

The bond energy of each molecule varies with the type of bond in the molecule. Stronger bonds require a higher bond energy and vice versa.

Therefore, the phrase that defines bond energy is the energy required to break a chemical bond.

Answer:

D. Energy input needed to break bonds of reactants.

Explanation:

Activation energy is the minimum amount of energy required to initiate a chemical reaction by breaking the bonds of the reactants. It is the energy needed to reach the transition state, where the reaction can proceed, and new chemical bonds can be formed to create the products. The activation energy is the energy barrier that must be overcome for a reaction to occur.

Once the reactants have enough energy to overcome the activation energy, the reaction proceeds spontaneously, and energy is released when new bonds form in the products.

Answer:

the answer is 51 L please brainliest

Explanation:

The volume of  2. 0 moles of nitrogen at 720 torr and 20. 0°C is 51 L

Using the formulae,   PV=nRT

Recall that

1 torr= 0.00132atm

Such that

P=720torr =720 x  0.00132atm= 0.95atm

Also,

V= 20°C= 20+273= 293K

R=0.08206L-atm/mol-K

Solving, we have that

PV=nRT

0.95×V= 2×0.08206×293

V= 2×0.08206×293/ 0.95

V= 50.62L

Rounded to  51 L.

In the system at equilibrium liquid water-water vapor, if liquid water is added to the system, more liquid water molecules will change to water vapor until a new equilibrium is reached.

If a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.

Let's consider the following system at equilibrium.

H₂O(l) + heat ⇄ H₂O(g)

Which statement best describes what will happen if liquid water is added to the system?

In the system at equilibrium liquid water-water vapor, if liquid water is added to the system, more liquid water molecules will change to water vapor until a new equilibrium is reached.

Answer:

More liquid water molecules will change to water vapor until a new equilibrium is reached. Yes. This will happen to counteract the excess of liquid water.

All of the liquid water molecules that are added will become water vapor. No. Some liquid molecules will change to vapor to attain a new equilibrium.

More water vapor molecules will change to liquid water until a new equilibrium is reached. No. The change will happen in the inverse sense.

All of the liquid water molecules that are added will remain liquid water. No. Some liquid molecules will change to vapor to attain a new equilibrium.

Answer:

[tex] ZnSO_4 + Li_2CO_3 \longrightarrow ZnCO_3 + Li_2SO_4 [/tex]

Explanation:

Here a reaction is given to us and we need to balance the equation . The given reaction is ,

[tex] ZnSO_4 + Li_2CO_3 \longrightarrow ZnCO_3 + Li_2SO_4 [/tex]

So here , we can make a table as ,

[tex]\begin{array}{c|c} \\ LHS & RHS \\\\ Zn = 1 & Zn = 1 \\\\ SO_4 = 1 & SO_4 =1\\\\ Li = 2 & Li= 2 \\\\ CO_3 = 1 & CO_3 = 1 \end{array}[/tex]

We can see that the number of elements and ions is same on both LHS and RHS . Hence the reaction is already balanced .

Therefore the final reaction would be same as before that is ,

[tex] ZnSO_4 + Li_2CO_3 \longrightarrow ZnCO_3 + Li_2SO_4 [/tex]

Acid-base conjugate pair forms when the element donates a proton and another species acquires it. [tex]\rm H_{2}O[/tex] and [tex]\rm H_{3}O^{+}[/tex]are the base-conjugate acid pair.

Acids are the species or element and compounds that donates proton or hydrogen ions to form a conjugate base.

Bases are the elements or compounds that acquires protons or hydrogen ions and form a conjugate acid pair.

Conjugate acids and bases are the species or the products formed when the protons or hydrogen ions are increased or decreased in their chemical structures.

The reaction can be shown as,

[tex]\rm H_{2}PO_{4}^{-} + H_{2}O \leftrightarrows H_{3}O^{+} + HPO_{4}^{2-}[/tex]

From the reaction, it can be said that the water molecule acquired the hydrogen or the proton ions and the hydronium ion produced as a result is the conjugate acid of the water base.

Therefore,  [tex]\rm H_{2}O[/tex]and [tex]\rm H_{3}O^{+}[/tex]are the base-conjugate acid pair.

"Soaps are made from natural ingredients, such as plant oils (coconut, vegetable, palm, pine) or acids derived from animal fat. Detergents, on the other hand, are synthetic, man-made derivatives. While soap is limited in its applications, detergents can be formulated to include other ingredients for all sorts of cleaning purposes. Perhaps the most common and versatile of these ingredients are surfactants … surface active agents.

The main difference between soap and detergent is the ingredients. Soaps are made with biodegradable ingredients such as oils, lye and fats. ... Both clean clothes well, but detergents are more effective on stains and with brightening clothes. However, soap is kinder on the environment and skin. "

26.7% is the percent composition by mass of sulfur in a compound named magnesium sulfate. Explanation: Molar mass of compound = 120 g/mol.

Sulfur trioxide (triangular planar) formed by double covalent bonds, is a compound that presents polar bonds although the dipole moments associated with each bond are canceled by symmetry, resulting in apolar molecules.

It is a nonpolar molecule that contains one sulfur atom bonded to three oxygen atoms.

Therefore, we can conclude that SO3 is a nonpolar molecule due to its geometry (trigonal planar) and the absence of a lone pair of electrons.
