Mercury has a density 13.6 g/mL at room temperature. It is 3:30 PM on Tuesday, and the sky is covered by 70% clouds. The atmospheric temperature is 298K and the pressure is 101.3 kPa. My favorite color is dark brown because it reminds me of dirt, camping, and the outdoors in general. I also like a very light shade of gray, because it looks like fresh fallow snow on a cloudy day (which happens to be my favorite weather). My birthday is July 31st. In college, I had 7 goldfish, and they were all named 'Roger'. If the mercury has a volume of 50.0 mL, what is its mass?

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

your answer would be “dry”

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

lol for the pointsss
