How many moles of oxygen are required to make 4 moles of water?​

Chemistry

Answer:

2 moles of oxygen

Explanation:

Basic Equation (given) :

2H₂ (g) + O₂ ⇒ 2H₂O (g)

  • From this, we understand for every 2 moles of water, 1 mole of oxygen is needed

Taking the number of moles of oxygen and water in proportion :

  • 1 : 2
  • 1 × 2 : 2 × 2
  • 2 : 4

Therefore, 2 moles of oxygen are required to make 4 moles of water.

As per the given equation, we can infer that :

For getting 2 moles mole of water, 1 mole of oxygen gas was required. so to get 4 moles of water we need :

We just have to multiply the whole reaction by 2 on both sides, in order to get 4 moles of H2O on product side.

\qquad \qquad \rm4 \: H_2 + 2 \: O_2  \rightarrow4 \: H_2O

therefore, we need

\qquad \sf  \dashrightarrow \: 2 \times 1 = 2 \: moles \:  \: oxygen \: gas

What mass of Ba3(PO4)2 is contained in 1575 mL of a 0.35 M solution of Ba3(PO4)2?
irina [24]

Answer:

= 331.81 g

Explanation:

Molarity is calculated by the formula;

Molarity = Moles/volume in liters

Therefore;

Moles = Molarity ×Volume in liters

          = 0.35 M × 1.575 L

          = 0.55125 Moles

But; Molar mass of Ba3(PO4)2 is 601.93 g/mol

Thus;

Mass = 0.55125 moles × 601.93 g/mol

         <u>= 331.81 g</u>

Complete combustion of 8.10 g of a hydrocarbon produced 25.9 g of CO2 and 9.27 g of H2O. What is the empirical formula for the h
balu736 [363]

CxHy     +  O2    -->    x CO2     +    y/2  H2O

 

Find the moles of CO2 :     18.9g  /  44 g/mol   =    .430 mol CO2   = .430 mol of C in compound

Find the moles of H2O:      5.79g / 18 g/mol     =     .322 mol H2O   = .166 mol of H in compound

 

Find the mass of C and H in the compound:

                             .430mol  x 12  =  5.16 g C

                              .166mol  x 1g   = .166g H   

 

When you add these up they indicate a mass of 5.33 g for the compound, not 5.80g as you stated in the problem.

Therefore it is likely that either the mass of the CO2 or the mass of H20 produced is incorrect (most likely a typo).

In any event, to find the formula, you would take the moles of C and H and convert to a whole number ratio (this is usually done by dividing both of them by the smaller value).

hi:) anyone able to explain no.2 of what happens to particles of a solid that is heated until it melts? I don’t understand it. T
Viefleur [7K]
In a solid the particles are all really close together and stuck like that. As the solid melts and becomes a liquid the particles spread out. A solid won’t easily change its shape because the particles are bound together but in a liquid the shape is more fluid, take water when you pour it into a container it will change to fit the shape of a container this is because the particles aren’t as close and can move around. The particles of a solid change when it melts because it is changing states to a liquid.
