What are the four types of severe storms

1 answer:

8 0

Storms are disturbances in atmospheric conditions. The four severe storms are thunderstorms, lightning, heavy rain, and blizzards.

<h3>What are blizzards?</h3>

Blizzards are the type of storm that includes high wind at 40 km/h and also have snow and cold air that makes the temperature drop and causes poor visibility.

Thunderstorms and lightning occur with high electrical charge release during high wind and rain. Heavy rains are severe types of storms as they can cause a flood.

5.60 g of an unknown gas at STP fills a 500 mL flask. What is the molar mass of the gas

ale4655 [162]

Hey there!

From ideal gas equation we know, PV = nRT

All the terms have their usual significance.

PV =w/M * RT

( where , n is number of moles = w/M, we = weight of gas, M = molecular weight of the gas)

Therefore, PV = wRT/M

At standard conditions , value of pressure, P = 1atm and standard temperature, T = 273K

And value of universal gas constant, R = 0.082 lit. atm. K⁻¹.mol⁻¹

Given that, weight of gas,

w = 5.60g and volume of gas,

V = 500mL = 0.5 Liters

Therefore, substituting all the value, we get :

Molar mass = 5.60 * 0.082 * 273 / 1 * 0.5

Molar mass = 250.7232 g/mole

Which is the noble gas notation for chlorine?

Mandarinka [93]

Answer: The electronic configuration of Chlorine will be $[Ne]3s^23p^5$

Explanation: Chlorine is an element which belongs to the P-block of the periodic table. Its atomic number is 17.

Atomic Number = Number of electrons

Number of electrons = 17

The nearest noble gas which lies to Chlorine is Neon which has 10 electrons. Rest of the 7 electrons are filled in the 3s and 3p orbitals. Hence, the electronic configuration of Chlorine is

$[Cl]=[Ne]3s^23p^5$
