Answer:
Are you tryna make a 3d object or you need a drawing?
Explanation:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again
Protons and neutrons have about the same mass. Electrons are the smallest out of the three, in fact, protons weigh 1,836 times more than an electron.
Answer:
CH4+ 2Cl2→CH2Cl2+ 2HCl
Explanation:
mass is 132.8`125
as methane and dichlormethane has the same molar ration 1 to 1
mol of ch4 is 1.5625
so 1.5625 times mr of ch2cl2 is 132.8125
Answer:
A quantum of electromagnetic energy is called photon
Explanation:
A photon corresponds to an elementary particle that composes the light, without any internal structure that is known at the moment. Said particle carries visible, ultraviolet, infrared, X-ray, gamma and other forms of electromagnetic radiation particles. The photon can travel in a vacuum at a constant speed and lacks mass or electric charge.
First you have to look at the mole ratios of the reactants and products and that ratio is 2:2:2 or you can reduce that to 1:1:1. That means an amount of peroxide will produce the same amount of oxygen gas. If there are 8 mol of peroxide will give 8 mol of oxygen gas
