Vitek1552 [10]3 years ago
7 0

Answer:

Reactions of Alkenes - Pearson

Explanation:

most Alkenes reaction fall into this large class of electrophilic additions to alkenes.

the pi bond as a nucleophile. A strong electrophile attracts out the electrons out of the pi bond to form a new sigma bond. generating a carbocation

State the assumptions that the kinetic-molecular theory makes about the characteristics of gas particles
Marrrta [24]

The kinetic-molecular theory explains the properties of the gases in terms of energy, size and motion of their particles.


The assumptions that the kinetic-moletuclar theory makes about the characteristics of gas particles are:


1. Gases are constituted by a large amount of particles (atoms or molecules) symilar to solid spherical sphers, in constant and random motion.


2. Gas particles move in straight line until collide with another particle or the walls of the vessel.


3. Gas particles are so small compared to the distances that separate them, that the volume of the gas is considered empty space: the volume of the particles is neglected.


4. Beside the already mentioned collisions with the walls of the vessels or between the particles, there is no interaction (attractive or repulsive forces) acting on the gas particles.

 

5. The collisions between gas particles or with the walls of the vessel are elastic: there is not loss of energy.


6. The average kinetic energy of the particles in a gas depends only on the absolute temperature of the gas: at a given temperatue every gas have the same average kinetic energy.


That collection of assumptions are used to explain such things as: the relation  of pressure withthe  number of particles, the relation of pressure and temperature, the relation of pressure and volume, the relation of volume and temperature, Avogadro's hypothesis (relation of volume and number of particles), Dalton's Law of partial pressures, and both effusion and difusion.

How to calculate the atomic mass of Cl​
slega [8]
To find the atomic mass of chlorine, the atomic mass of each isotope is multiplied by the relative abundance (the percent abundance in decimal form) and then the individual masses are added together. The atomic mass of chlorine is 35.45 amu.

Is this the correct procedure for cleaning volumetric glassware prior to making a measurement: first, rinse with tap water. Seco
Bogdan [553]

The steps to be followed while cleaning volumetric glassware are:

1. Remnants from the previous measurements are wiped off with the help of paper towel.

2. The glassware is then soaked overnight in warm soap solution.

3. Then before rinsing with tap water, the glassware are scrubbed with an appropriate brush.

4. After scrubbing, the glassware is rinsed thoroughly with tap water in order to make sure there are no traces of soap solution.

5. The glassware is then rinsed with de-ionized water and finally with the solution that would be used for the volumetric measurement.

An iron ore was found to contain 92.0% pyrite (fool's gold). Pyrite has the formula FeS2and is 46.5% iron. How many grams of iro
Liula [17]
Firstly calculate the grams in the last 8 percent before moving onto the pyrite section.
50.8x0.08=4.064g
We know that iron ore in this case has 92 percent pyrite which contains 46.5 percent iron so we do 50.8x0.92=46.736g from this we need to find 46.5 percent of the iron content in the 92 percent pyrite section then add this answer to the 8 percent of iron ore we found at the start.46.736x0.465=21.73224g
21.73224g+4.064=25.79624g of iron ore 25.8g(3sf)

You carefully weigh out 16.00 g of CaCO3 powder and add it to 64.80 g of HCl solution. You notice bubbles as a reaction takes pl
bulgar [2K]

Answer: Mass of CO_2  produced in this reaction was 6.56 grams

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

CaCO_3(s)+2HCl(aq)\rightarrow H_2O(l)+CO_2(g)+CaCl_2(aq)

Mass or reactants =  Mass of CaCO_3+ mass of HCl = 16.00 + 64.80 = 80.80 g

Mass of products  = mass of aqueous solution + mass of CO_2 + = 74.24 + x g

Mass or reactants = Mass of products

80.80 g = 74.24 + x g

x = 6.56 g

Thus mass of CO_2  produced in this reaction was 6.56 grams
