Answer:

The edge of boiling over of the substance relies upon the strength of holding between the particles, unequivocally the intermolecular powers between the atoms. The intermolecular powers that exist between the particles relies upon the idea of the atoms like extremity, sub-atomic weight, design of the atom, and so forth In testing the edge of boiling over of the two given fluids, the expansion in edge of boiling over can be noticed for the compound with higher limit. This demonstrates that there is lower intermolecular power in the compound with lower atomic weight.

Explanation:

Hope this helps

The strength of holding between the particles, namely the intermolecular forces between the atoms, determines the substance's edge of boiling over. The intermolecular forces between the particles depend on concepts related to atoms, such as extremities, sub-atomic weight, atom design, and so on.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.

But when it comes to the name atom, we must travel back to 400 B.C. ancient Greece. The Greek word atomos, which meaning "uncuttable," was proposed by Democritus, a renowned philosopher. In the end, all matter could be reduced to distinct, tiny particles, or atomos, he said.

When the two supplied fluids' edges of boiling over are tested, the compound with the greater limit exhibits an expansion in the edge of boiling over. This illustrates that the compound with a lower atomic weight has a lower intermolecular power.

Thus,The intermolecular forces between the particles depend on concepts related to atoms.

A calculated field will appear in the field list window, but will not take up space in the source data. In the example shown, a calculated field called "Unit Price" has been created with a formula that divides Sales by Quantity. The pivot table displays the calculated unit price for each product in the source data.

Explanation:

The PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.

Calculated fields are defined as the fields whose values are determined by other fields' values and perhaps external sources. Data from other fields can be calculated using calculated fields. Calculating the sum of two fields is a simple example, but more complicated calculations, such averaging values from multiple tables or even gaining access to external data, are theoretically feasible.

PivotTable Field List is defined as the Areas part of the Field List allows you to organize the fields wherever you like. It features a field section where you select the fields you wish to display in your PivotTable. Using a pivot table is an interactive method for quickly summarizing enormous amounts of data.

Answer:

Static electricity is the result of an imbalance between negative and positive charges in an object. ... When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other.

Answer: 1) Contact between two substances.

Explanation:

#1 When fuel is running through pipes, there is a lot of contact between the fuel and the pipe.

This problem is asking for the major alkyne product that is formed when 1,1‑dichloro‑3‑methylbutane reacts with sodium amide (NaNH₂) ignoring any byproduct.

Thus, we can firstly say that such reaction of an alkyl halide with a strong base such as sodium amide is able to remove the halogen-based substituents and hence form insaturations in the form of double or triple bonds depending on the degree of substitution.

For instance, if one halogen substituent, then an alkene will be formed; but if two, then an alkyne (like this problem).

In such a way, as shown on the attached figure, the product will be 3-methylbutyne due to the loss of two chlorine substituents.

Answer:

54.75 mL

Explanation:

First calculate the number of moles of NaCl in the 150mL solution of NaCl

0.0365 moles should be present on 1000cm3 or 1dm3 of water.

1L = 1 dm3

1 mL = 1 / 1000 dm3

150 mL = 150/1000 dm3 = 0.15 dm3

If x moles are present in 0.15 dm3,

x/ 0.15 = 0.0365

We get x= 0.0365 × 0.15 mol

Now x amount of moles should be taken from the initial 0.100 M NaCl solution

So 0.1 moldm-3 = 0.0365× 0.15 mol / V

we get V = 0.05475 dm3

V= 0.05475 L

V= 54.75 mL

n-propylbenzene will travel the largest distance because it interacts most effectively with the stationary phase followed by phenol and benzoic acid will travel the least distance because it interacts poorly with the mobile phase.

Thin layer chromatography involves the separation of a mixture using a stationary phase made of  silica gel on a glass plate and an appropriate mobile phase. The extent of separation is highly dependent on the magnitude of interaction between the solute and the mobile phase. and stationary phase.

The first step in thin layer chromatography is to make a thin mark at the bottom portion of the plate then spot the plate with the sample. The mobile phase is now introduced into the TLC chamber a little below the mark. The plate is now placed in the stationary phase such that the mark is above the solvent level.

The TLC chamber is now covered and enough time is allowed for separation to occur. The spots can be seen using a suitable indicator dye or with a the aid of UV light

After the  separation of a homogeneous, liquid mixture containing benzoic acid, n-propylbenzene, and phenol, provided a 4:1 hexane to ethyl acetate solution as the eluent, we can see that n-propylbenzene will travel the largest distance because it interacts most effectively with the stationary phase followed by phenol and benzoic acid will travel the least distance because it interacts poorly with the mobile phase.

Explanation:

The balanced equation says that we'll get 1 mole of H2 for every 1 mole of Mg.  50 grams of H is 50g/2 g/mole = 25 moles of H2.  That means we'll need 25 moles of Mg.  Convert that into grams:  (25 moles Mg)*(24.3 g/mole) = 607 grams Mg.  

At STP, all gases occupy 22.4 liters/miole.  That means 25 moles of H2 would occupy (25 moles)*(22.4 liters/mole) = 560 liters.

Answer: o.125 moles of gas X with a molar mass of 240

Explanation:

2.8 dm3 of gas X at STP has equal mass with 11.2 dm3 of C2H6 at STP. What is the number of mole if gas X has 30 grams?

the molar volume of any gas at STP is the volume of 1 mole at STP

and is 22.4 L

the C2H6 has a volume of 11.2L at STP so it has 0.5 moles

C2H6 has a molar mass of (2 X 12) +(6 X 1) = 24 + 6 = 30

0,5 moles weighs 15 gm at STP with

so 15 gm at STP with 2.8 L for gas X

PV=nRT

P=1 atm

T =273.2k

V =2.8

R =0.082

n = PV/RT = (1 X 2.8)/(0.082 X 273.2) =0.125 moles of gasX

the weight of gas X is 30 gms

so 30/.125 =240 g/mole = molar mass of gas X

Accuracy of a measured value refers to how close a measurement is to the correct value. The uncertainty in a measurement is an estimate of the amount by which the measurement result may differ from this value. Precision of measured values refers to how close the agreement is between repeated measurements.

Explanation:

When energy is added to a system during phase change, the particles move faster.

When a substance is heated, the internal energy within a system associated with the motion of particles and that can be added to a substance is called thermal energy.

During a phase change, when more energy is added to the system, the particles within the system will have greater motion and the temperature will increase.

The attractions that hold molecules together are electrostatic forces. The correct statement about the attractions that hold particles is that attractions between particles break when  attractions due to Electrostatic forces when particles move fast enough these forces can no longer keep particles together.

Rubber band  is not a perfect comprehension for Bonds in a substance when considering phases change because for a phase change from liquid to gas the bonds do not break completely the particles can still slide past each other.

The amount, in grams, of water, that the student originally started with would be 252 g

From the balanced equation of the reaction, the ratio of H2O to H2 is 1:1. Thus for every 1 mole of water that is separated, 1 mole of H2 is produced.

Recall that: mole = mass/molar mass

Mole of 28.0 g H2 produced = 28/2

                                              = 14 moles

Equivalent mole of H2O would, therefore, be 14 moles.

Mass of 14 moles H2O = mole x molar mass

                                      = 14 x 18

                                      = 252 g
