Answers

The amount of heat loss to the inner 2.35g styrofoam cup is 19.6 joules.

Given in question that;

The calorimeter made of Styrofoam loses heat. Styrofoam's specific heat is 1.34 j/g*c, assuming a temperature change of 6.22 c for the reaction between hcl (aq) and naoh (aq).

Change in temperature; ∆T = 6.22°c

weight of substance; W = 2.35 g

Specific heat of styrofoam; Cp = 1.34 j/g°c

To find heat loss;

Q = w x Cp x ∆T

where, change in temperature; ∆T

Weight of substance; W

Specific heat of 2.35g of material; Cp

Thus, Q = 2.35 g × 6.22°c × 1.34 j/g°c

Mass percentage is a term that represents the concentration, basically mass by mass percentage. It tells about the percentage of a component in a whole component. Therefore, 25.85% is the percentage by mass of sodium chloride in the solution.

What is percentage by mass?

Mass percentage represents the the percentage of each element that is making a particular compound. Mass percentage does not have any unit as numerator and denominator contains the same unit.

Percentage of mass = (component’s mass ÷ total mass) x 100%

Total mass = 165.0g+ 54.3g

mass of sodium =56.7 g

Percentage by mass = (56.7 g/  219.3g )×100

Answers

The vapour pressure of mentioned solution of sucrose and water is 23.5 mm Hg.

The formula to be used for the calculation is from Raoult's law -

vapour pressure = vapour pressure of water × mole fraction

Number of moles = mass/molar mass

Molar mass water = 18 g/mol

Molar mass sucrose = 342.3 g/mol

Moles of water = 250/18

Moles of water = 13.9

Moles of sucrose = 40/342.3

Moles of sucrose = 0.12

Mole fraction of water = 13.9/(0.12 + 13.9)

Entropy decreases during the proposed synthesis of solid nitrogen

What is entropy?

One of the most crucial ideas in both information theory and physics is entropy. Entropy is a measure of the degree of chaos in a physical or biological system that is used informally. The less information we know about a system, the higher its entropy.

In the middle of the 19th century, debates about the effectiveness of heat engines gave rise to the idea of entropy. Students have struggled with Carnot's cycle and other sorts of expansion of real and ideal gases for generations without ever fully understanding why they were doing so.

A change in entropy, S, was defined in several previous textbooks using the equation:

S = Qreversible / T (i)

where Q denotes the amount of heat present and T denotes the thermodynamic temperature. However, it is more typical today to find entropy stated in terms of the level of disorder in the system and to define the entropy change, S, as:

ΔS = -ΔH/T (ii) (ii)

When we raise a substance's temperature in a chemical process, molecular mobility increases along with entropy. In contrast, molecular mobility and entropy should both decrease as a substance's temperature is dropped.

Hence, entropy decreases during the proposed synthesis of solid

Which substance is important to the structure of the cell membrane because it helps the cell membrane keep its shape?

Answers

Phospholipid is the substance which is important because it helps the cell membrane keep its shape.

The primary element of cell membranes is phospholipid. All cell membranes have a double layer of them, which are arranged in a line. By preventing some substances from passing through, the double layer of phospholipids that develop helps to safeguard the cell.

A lipid called cholesterol prevents cell membranes from becoming overly rigid.The cell membrane is made up of a particular class of lipids called phospholipids. Phospholipids are amphipathic, which means they include both hydrophobic and hydrophilic components that can mix with water.

Hence, Phospholipid is the substance which is important because it helps the cell membrane keep its shape.
