Balance the following chemical equation (if necessary):
SiCI4 (s) + H2O(I) → H4SiO4 (aq) + HCI(aq)
Answer: SiCl₄(s) + 4 H₂O(l) → H₄SiO₄(aq) + 4 HCl(aq)
Explanation:
You can pretend there is an imaginary line splitting the chemical equation into two on the arrow to help balance the equation.
Balance out chlorine on both sides, add the coefficient 4 to HCl
now there are 4 chlorines on the left and the right side.
Then, balance out Hydrogen on both sides, add the coefficient 4 to H₂O
now, there are 4*2=8 hydrogens on the left and 4+4=8 hydrogens on the right.
Counting the total number of atoms on both sides of the arrow, the equation is balanced
1 Si = 1 Si
4 Cl = 4 Cl
4 O = 4 O
8 H = 8 H
[tex]\\ \sf\longmapsto SiCl_4+4H_2O\longrightarrow H_4SiO_4+4HCl[/tex]

explain how the atoms are held together by tge covalent bond in a molecule of hydrogen?
Answer:
A hydrogen molecule forms from two hydrogen atoms, each with one electron in a 1 s orbital. The two hydrogen atoms are attracted to the same pair of electrons in the covalent bond. The bond is represented either as a pair of “dots” or as a solid line. Each hydrogen atom acquires a helium-like electron configuration. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units. The hydrogen molecule is the simplest substance having a covalent bond.

How many grams of nitrogen are in 1.5 moles of nitrogen atoms
Answer:
42 grams
Explanation:
the conversion between moles and grams is by using the molar mass of the substance.
The molar mass for a nitrogen atom is 14.00 g/mol.
N2 has two nitrogen atoms, so its molar mass is 28.00 g/mol
To find how many grams are in 1.5 moles;
[tex]28g/mol*1.5mol[/tex]
the units of mols cancels out, leaving one with units of grams of N2

How many grams of S are in 475 g of SO2?
There are 237. 5 g of Sulfur,S in 475 g of SO2?
Calculation of grams of SulfurFrom the question, we can say that
The molar mass of sulfur = 32 g/molThe molar mass of oxygen = 16 g/molTherefore,
The molar mass for SO2 = 32 + (16 × 2) g/mol = 64 g/mol
Now,
If 1 mole of SO2 contains 1 mole of S
Then 64 g of SO2, will contain 32g of S;
Such that
475 g of SO2 will give { [tex]\frac{ 32g of S) ( 475 g of SO2)}{64 of SO2}[/tex] } = 237. 5 g of Sulfur.

In the given question, 1.3kg is the mass of [tex]\rm O_2[/tex] that will react with 400g of [tex]\rm C_4H_{10}[/tex] and 34.4 moles of [tex]\rm H_2O[/tex] are formed in the reaction.
Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol).
a) To determine the mass of [tex]\rm O_2[/tex]that will react with 400 g of [tex]\rm C_4H_{10}[/tex], we need to use stoichiometry to determine the mole ratio of [tex]\rm C_4H_{10}[/tex] to [tex]\rm O_2[/tex]in the balanced chemical equation.
[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]
From the equation, we can see that 2moles of [tex]\rm C_4H_{10}[/tex] react with 13 moles of [tex]\rm O_2[/tex]. Therefore, we can set up a proportion:
2 mol / 13 mol [tex]\rm O_2[/tex]= 400 g [tex]\rm C_4H_{10}[/tex] / x g [tex]\rm O_2[/tex]
where x is the mass of [tex]\rm O_2[/tex] that will react with 400 g of [tex]\rm C_4H_{10}[/tex] .
Solving for x, we get:
x = (13 mol [tex]\rm O_2[/tex] [tex]\times[/tex] 400 g [tex]\rm C_4H_{10}[/tex] ) / (2 mol [tex]\rm C_4H_{10}[/tex] )
x = 1.3 kg [tex]\rm O_2[/tex]
b) To determine the number of moles of water formed in part a), we need to use stoichiometry again to determine the mole ratio of [tex]\rm C_4H_{10}[/tex] to [tex]\rm H_2O[/tex] in the balanced chemical equation.
[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]
From the equation, we can see that 2moles of [tex]\rm C_4H_{10}[/tex] react with 10 moles of [tex]\rm H_2O[/tex] . Therefore, we can set up another proportion:
2 mol [tex]\rm C_4H_{10}[/tex] / 10 mol [tex]\rm H_2O[/tex] = 400 g [tex]\rm C_4H_{10}[/tex] / x mol [tex]\rm H_2O[/tex]
where x is the number of moles of [tex]\rm H_2O[/tex] formed.
First, we need to convert 400 g of [tex]\rm C_4H_{10}[/tex] to moles:
400 g [tex]\rm C_4H_{10}[/tex] [tex]\times[/tex] (1 mol [tex]\rm C_4H_{10}[/tex] / 58.12 g [tex]\rm C_4H_{10}[/tex] ) = 6.88 mol [tex]\rm C_4H_{10}[/tex]
Now we can solve for x:
2 mol [tex]\rm C_4H_{10}[/tex] / 10 mol [tex]\rm H_2O[/tex] = 6.88 mol [tex]\rm C_4H_{10}[/tex] / x mol [tex]\rm H_2O[/tex]
x = (10 mol [tex]\rm H_2O[/tex] [tex]\times[/tex] 6.88 mol [tex]\rm C_4H_{10}[/tex]) / (2 mol [tex]\rm C_4H_{10}[/tex] )
x = 34.4 mol [tex]\rm H_2O[/tex]
Therefore, 1.3 kg of [tex]\rm O_2[/tex] will react with 400 g of [tex]\rm C_4H_{10}[/tex] .34.4 moles of water are formed when 400 g of [tex]\rm C_4H_{10}[/tex] .

What is mole concept?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
In case of determining the mass of propane at STP , first the number of moles is determined ,
