The chemical formula of butane is C4H10.
<span>Germane is the chemical compound with the formula GeH₄, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium.
</span>In chemistry, sigma bonds (σ bonds) are the strongest type of covalent chemical bond. They are formed by head-on overlapping between atomic orbitals. Sigma<span> bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups.

Answer:
I think its E. iron and iron oxide have the same properties if it's not e its d for sure
Explanation:
iron + oxygen → iron oxide. 4 Fe + 3 O2 → 2 Fe2O.
Answer:
thermal circulation cells
Explanation:
The three cell model of global wind circulation model is the model that give some us the relationship between the wind patterns that is present on our earth to the sunlight (heat) received from the sun.
Now the sunlight (heat) received from the sun is dependent on the earth axis tilt and on the heating of the earth’s surface due to solar heating therefore these two comes under the global circulation model apart from that the movement of air is also dependent on the Coriolis force and hence it also comes under the global wind circulation model but thermal circulation cells are the cells that are described in this model and hence they don’t come under this model therefore thermal circulation cell is the option which is absent in the three cell model of global circulation. Therefore option “c” is correct.
Answer: Option A) 2 atoms
Explanation:
4Al + 302 ---> 2Al2O3
4 moles of Al reacts with 3 molecules of O2
So 1.10 moles of Al should reacts with Z molecules of O2 (Assume Z is unknown)
i.e 4 moles of Al = 3 molecules of O2
4 moles of Al = 6 atoms of O2 (since 1 molecule of oxygen has two atoms of oxygen)
1.10 atoms of Al = Z atoms of O2
To get the value of Z, cross multiply
Z x 4 moles = 6 atoms x 1.10 moles
4Z = 6.6
Divide both sides by 4
4Z/4 = 6.6/4
Z = 1.65 atoms (approximately 2 atoms)
Thus, 2 atoms of the excess reactant oxygen remains.
