A compound of copper and sulfur contains 88.39 g of metal and 44.61 g of nonmetaL How many grams of copper are in 5264 kg of com

Dahasolnce [82]

Answer :

The mass of copper in 5264 kg of compound are, 3498383.158 g

The mass of sulfur in 5264 kg of compound are, 1765616.842 g

Explanation : Given,

Mass of metal = 88.39 g

Mass of non-metal = 44.61 g

Given mass of compound = 5264 kg = 5264000 g (1 kg = 1000 g)

Now we have to calculate the total mass of compound.

Total mass of compound = Mass of metal + Mass of non-metal

Total mass of compound = 88.39 + 44.61 = 133 g

Now we have to calculate the mass of copper.

As, 133 g of compound contains 88.39 g of copper

So, 5264000 g of compound contains $\frac{5264000}{133}\times 88.39=3498383.158g$ of copper

The mass of copper in 5264 kg of compound are, 3498383.158 g

Now we have to calculate the mass of sulfur.

As, 133 g of compound contains 44.61 g of sulfur

So, 5264000 g of compound contains $\frac{5264000}{133}\times 44.61=1765616.842g$ of sulfur

The mass of sulfur in 5264 kg of compound are, 1765616.842 g

A central atom that is sp3 hybridized could bind up to how many other atoms?

inna [77]

Answer: up to 4 other atoms.

Explanation:

<em>Hybridization sp</em>³ means that the atom has 4 equal orbitals formed by the combination of 1 s and 3 p orbitals.

Each of these sp³ orbitals is a place for a chemical bonding.

Hence, since each orbital is able to bind a different atom, you conclude that <em>a central atom that is sp³ hydridized could bind up to 4 other atoms.</em>

This is precisely the case for carbon (C) atoms.

Carbon has atomic number 6. So its electron configuration is 1s² 2s²p².

The four electrons in the level 2, those shown in 2s² 2p², are in two different orbitals: two are in the orbital 2s and two are in the orbitals 2p.

This diagram shows how those 4 electrons fill the orbitals

2s⇅ 2px↑ 2py↑

The two 2s electrons have lower energy level than the 2px and 2 py electrons, but the difference is not too big.That is why one of the electrons in the 2s ortital can be promoted to the empty 2pz orbital, and you get 4 equal hydridized ortibals, so called sp³.

And that is why, carbon (C) ends up with 4 equal (hydridized) orbitals which can bind up to 4 different atoms, including other carbon atoms, and so, form long chains and, virtually, infinite compounds.

Why does liquid bromine react slowly as compared to bromine vapor

babunello [35]

This has to do with the molecular arrangement of the phases of matter. Since the molecules of a gas are widely dispersed compared to the liquid, it would have a faster rate of reaction because the molecules interact more frequently through rapid collisions. This is the reason why solid substances do not readily react. They need a medium, either in liquid form or gas form.
