What is the oxidation number of H4SiO4?
The oxidation number of hydrogen is +1 and the oxidation number of oxygen is -2. Since the compound is neutral, the oxidation number of silicon in H4SiO4 is +4.
How do you balance SiCl4 plus H20 equals H4SiO4 plus HCl?
To balance the equation SiCl4 + 4H2O → H4SiO4 + 4HCl, you first balance the silicon atoms by putting a coefficient of 1 in front of SiCl4 and H4SiO4. Then balance the chlorine atoms by adding a coefficient of 4 in front of HCl. Next, balance the hydrogen atoms by placing a coefficient of 4 in front of H2O. This gives you a balanced equation: SiCl4 + 4H2O → H4SiO4 + 4HCl.
How many atoms of Si are in 237 g of Si?

How many ATOMS of silicon are present in 3.10 moles of silicon dioxide?
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
How many unpaired electrons does Si have?
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.
What is the oxidation number for h2sio4?
You probably mean H2SO4, where H +1; S +6;O-2.H2SiO4 does not exist. If it did the oxidation numbers of the constituent elements would be H +1; Si +6; O -2. The compound silicic acid is H4SiO4 (not isolatable) with H +1, Si +4 and O -2.
