Silicon (si) has two electrons in its outer p orbitals.
Explanation:
For the element of SILICON, you previously know that the atomic number shows the number of electrons. That indicates there are 14 electrons in a silicon atom. Looking at the design, you can see there are two particles in shell one, eight in shell two, and four in shell three. Si which is 4 elements from the left side of the table,first 2 electrons are s orbitals when next two electrons go to Si
Answer:
CoSO₄.7H₂O
Explanation:
Some salts are in its hydrate form to stabilize them. The hydrated form of CoSO₄ is:
CoSO₄.XH₂O
To find the hydration of the COSO₄ you must find the ratio of H₂O and CoSO₄ that is:
0.068921 moles H₂O / 0.0098459 moles CoSO₄ = 7
That means you have 7 moles of water per mol of CoSO₄ and the formula is:
<h3>CoSO₄.7H₂O</h3>
Answer:
Sound needs a medium through which to travel.
Explanation:
In space there is no air or medium. Sound waves need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.
I believe it is spontaneous generation
