Answer:
10.80
Explanation:
As per the equation, let us calculate the mole ratio. N2+3H2→2NH3. As per the equation one mole of nitrogen reacts with 1 mol of hydrogen.
In terms of mass. 28.01 g of nitrogen needs 3 mol of hydrogen or 6.048 g of hydrogen.
We can set up the ratio;

Important of Grignard Reagent :
Grignard reactions are main due to their capacity to form carbon-carbon bonds. Grignard reagents are powerful bases and will react with protic compounds which makes them exceptionally valuable implement for organic synthesis.
Grignard reagents react fastly with acidic hydrogen atoms in molecules such as alcohols and water. When a Grignard reagent reacts with water, a proton return back halogen, and the product is an alkane. The Grignard reagent therefore provides a trace for transforming a haloalkane to an alkane in two steps.
When reacted with water,
RMgX + H2O -------> R-H + MgOH X
R ---- Alkyl Group
X --- Halogen

Answer:
Using valence bond theory, HgCl2 is sp hybridized while PCl3 is sp3 hybridized.
Explanation:
sp hybridized molecules are largely covalent and cannot conduct electricity hence the nonconducting nature of HgCl2. PCl3 contains a lone pair and three unpaired electrons in sp3 hybridized orbitals.
Answer:
Transverse waves are known by motion being perpendicular to the waves movements. Longitudinal waves move in a direction parallel to the way the wave moves. Water waves are an example of both as they move in a clockwise motion.
Explanation:
( Sorry if it is not the best answer but I did my best by researching )
To find the number of molecules, you need to first convert the mass into number of mol using the molar mass of SO2, simply add the atomic masses of each element and the number of times each element appears in the formula from the periodic table.
Then divide the mass by that value and then use Avogadro’s number to find the molecules.
Multiply by 6.02 x 10^23 Molecules.
