Chemistry
1 answer:
natulia [17]3 years ago
3 0

Explanation:

de Broglie wavelength= h/mv

v=h/m x de Broglie wavelength

v= (6.626× 10^-34)/ (2347× 1.27 × 10^-38)

v= 22.229 m/s(according to Google scientific calculator)

am sorry I don't hv a calculator at hand

Dentify the reagents used to carry out the chlorination of benzene. a. cl2/ccl4 b. cl2/fecl3 c. cl2/nacl d. both b and c e. a, b
algol13

The reagents which are used to carry out the chlorination of benzene are   cl2/fecl3 and cl2/nacl

Chlorination is the process of disinfecting drinking water by introducing chlorine to eradicate viruses, germs, and parasites. To get drinking water with safe levels of chlorine, various techniques can be utilized. Chlorination is the technique of disinfecting and eradicating bacteria from drinking water by adding chlorine to it.

To get drinking water with safe levels of chlorine, various techniques can be utilized. Chlorine can be found as solid calcium hypochlorite (Ca(OCl)2), sodium hypochlorite solution (NaOCl), or compressed elemental gas. Chlorine is added to water as part of the chlorination process, however the chlorinating substance need not be pure chlorine.

What is meant when it is stated that WATER can ""Ionize"" to a certain extent? What are the products that are formed when water
never [62]

Answer:

Ionization is defined as the process by which the atoms accept or donate electrons and form positively or negatively charged species, called ions.

The ionization of water is known as the self-ionization or autoionization of water. This process involves the deprotonation of a water molecule and protonation of another water molecule to give hydroxide ion and hydronium ion, which exist in the state of chemical equilibrium.

H₂O + H₂O ⇌ H₃O⁺ + OH⁻

The pH of pure water is 7, neutral.

A gas occupies a volume of 40.0 milliliters at 20 c if the volume is increased too 80.0 milliliters at constant pressure, the re
Troyanec [42]
Charles law gives the relationship between temperature and volume of gases. It  states that the volume of gas is directly proportional to temperature at constant pressure. 
V / T = k 
where V - volume and T - temperature in Kelvin and k - constant 
\frac{V1}{T1} =  \frac{V2}{T2}
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
T1 - 20 °C + 273 = 293 K
substituting these values in the equation 
\frac{40.0 mL}{293 K}  =  \frac{80.0 mL}{T}
T = 586 K
temperature in celsius = 586 K - 273 = 313 °C
new temperature is 313 °C
