Look on the periodic table to find the element number
Answer: water
water can not be organic...but is is took by humans and plants because theur life dpends on it
Explanation:
Answer:
The correct option is: C. tetrahedral, polar
Explanation:
Trifluoromethane, also known as Fluoroform, is a chemical compound with the molecular formula CHF₃.
Since three fluorine atoms and one hydrogen atom is bonded to the central carbon atom and there are zero lone pairs on the carbon atom. Therefore, the<em> molecular geometry and shape of CHF₃ is tetrahedral</em>.
As there are three carbon-fluorine polar bonds in CHF₃ molecule, thus there is a net dipole moment. <em>Therefore, CHF₃ is a polar molecule.</em>
Although your question is incomplete, I believe 'B' is the answer, as the Oxygen separates from the Hydrogen
Answer: 7.07 grams
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require 1 mole of
Thus 0.052 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 1 mole of
Thus 0.052 moles of give = of
Mass of
Thus 7.07 g of will be produced from the given masses of both reactants.
