<span>the electrons change their energy states and photons in visible spectrum (and infrared spectrum) are emitted.More the losses, more would be the light, but at the same time, more would be the heat generated.So this necessitates that the metal used should have high resistivity (and hence high losses), good thermmal conductivity and high melting point.

hope it helps

Can you catch coronavirus from F.A.R.Ts?
ZanzabumX [31]

Answer:

No

Explanation:

Droplets or aerosols. When an infected person coughs, sneezes, or talks, droplets or tiny particles called aerosols carry the virus into the air from their nose or mouth. Anyone who is within 6 feet of that person can breathe it into their lungs.

Airborne transmission. Research shows that the virus can live in the air for up to 3 hours. It can get into your lungs if someone who has it breathes out and you breathe that air in.

Surface transmission. Another way to catch the new coronavirus is when you touch surfaces that someone who has the virus has coughed or sneezed on. You may touch a countertop or doorknob that's contaminated and then touch your nose, mouth, or eyes. The virus can live on surfaces like plastic and stainless steel for 2 to 3 days. To stop it, clean and disinfect all counters, knobs, and other surfaces you and your family touch several times a day.

Fecal-oral. Studies also suggest that virus particles can be found in infected people's poop. But experts aren't sure whether the infection can spread through contact with an infected person's stool. If that person uses the bathroom and doesn't wash their hands, they could infect things and people that they touch.

Given n2 (g) + 3 h2 (g) 2 nh3 (g), which scenario will allow you to eventually reach an equilibrium mixture involving these chem
mash [69]

<span>The only scenario that will allow you to reach an equilibrium mixture involving these chemicals is to place NH3 into a sealed vessel. This reaction requires pressures between 2100, 3600 psi, and temperatures between 300 and 550 degree Celsius. With this given temperature and pressure, the ammonia naturally decomposes into nitrogen and hydrogen gas at the same rate. When this happen, the concentrations of these chemicals become constant and the system is said to be at equilibrium.</span>

Ex 1) 45.2 g of Zn = _____ moles Zn<br><br> Ex 2) 0.568 moles Ag = _____ grams Ag
Jlenok [28]

the molar mass of Zn is 65

  • number of mole(n)=reacting mass/molar mass
  • n=45.2/65
  • =0.70g/mol

2.the molar mass of Ag is 108

  • 0.568=m/108
  • then cross multiply
  • m=0.568×108
  • m=61.3g
