Hello !

The number to the right of each element represents the number of the atoms of that element.


PO4 is taken twice so you will multiply 1 and 4 by 2.

Now we have 1*2=2 atoms of P


To the left,there is 2,so you will multiply all the elements by 2.It means that you'll multiply 2 (atoms of P) by 2 :


 2*2=4 atoms of phosphorus


ANSWER : 4

With white light, a team measured a 0.7% percent change with 3.5g of plant matter in a one liter container. Convert

Strike441 [17]

moles CO₂ = 5.57.10⁻⁴

<h3>Further explanation </h3>

A mole is a number of particles(atoms, molecules, ions) in a substance

Can be formulated :

$\tt mol=\dfrac{mass}{MW}$

0.7% percent change with 3.5g of plant matter

mass :

$\tt 0.7\%\times 3.5~g=0.0245~g$

moles :

$\tt moles=\dfrac{0.0245}{44}=0.000557=5.57.10^{-4}$

Rewrite the equation below using the correct conventions for stoichiometric coefficients. 2 BaCl2 + 2 H2SO4 → 2 BaSO4 + 4 HCl

vichka [17]

Answer:

$BaCl2+H2SO4 \rightarrow BaSO4+2HCl$

Explanation:

The given equation is:

$2 BaCl2+2H2SO4 \rightarrow2BaSO4+4HCl$

Based on the reaction stoichiometry:

2 moles of barium chloride (BaCl2) reacts with 2 moles of sulfuric acid (H2SO4) to form 2 moles of barium sulfate (BaSO4) and 4 moles of HCl

Although the reaction is balanced, the correct convention is to depict reactions in terms of the lowest molar ratio. Therefore the coefficients (2,2,4 and 4) can be divided by 2 to give:

$BaCl2+H2SO4 \rightarrow BaSO4+2HCl$

At STP, how many liters of oxygen are required to react completely with 3.6 liters of hydrogen to form water?

Delvig [45]

Should be 1.8L.
2 moles of hydrogen react with 1 mole of oxygen. If 2 moles of hydrogen is 3.6L, 1 mole of oxygen should be 1.8L.
