In the chemical reaction below, what Is the product? C+o2 -> Co2
vlada-n [284]

Answer:

CO₂

Explanation:

The product of the reaction is CO₂.

In a chemical reaction, the product is the substance usually found on the right hand side of the expression.

  Reaction equation is given as;

          C  +  O₂  →  CO₂  

In this reaction, C and O₂ are the reactants

  CO₂ is the product of the reaction.

  • This reaction is called a combination reaction in which two species combines to give a product.

Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?
MAVERICK [17]
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.

Explanation:

2. 2C_2H_6 + 7O_2 \rightarrow 4CO_2 + 6H_2O

First, we need to find the number of moles of CO_2 at 300K and 1.5 atm using the ideal gas law:

n= \dfrac{PV}{RT}= \dfrac{(1.5\:\text {atm})(33\:L)}{(0.082\:\text{L-atm/mol-K})(300K)}

=2.0\:\text{mol}\:CO_2

Now use the molar ratios to find the number of moles of ethane to produce this much CO_2.

2.0\:\text{mol}\:CO_2 \times \left(\dfrac{2\:\text{mol}\:C_2H_6}{4\:\text{mol}\:CO_2}\right)

=1.0\:\text{mol}\:C_2H_6

Finally, convert this amount to grams using its molar mass:

1.0\:\text {mol}\:C_2H_6 \times \left(\dfrac{30.07\:\text g\:C_2H_6}{1\:\text{mol}\:C_2H_6} \right)

=30.1\:g\:C_2H_6

3. 3Zn + 2H_3PO_4 \rightarrow 3H_2 + Zn_3(PO_4)_2

Convert 75 g Zn into moles:

75\:\text g\:Zn \times \left(\dfrac{65.38\:\text g\:Zn}{1\:\text{mol}\:Zn}\right)=1.1\:\text{mol}\:Zn

Then use the molar ratios to find the amount of H2 produced.

1.1\:\text{mol}\:Zn \times \left(\dfrac{3\:\text{mol}\:H_2}{3\:\text{mol}\:Zn}\right)=1.1\:\text{mol}\:H_2

Now use the ideal gas law PV=nRT to find the volume of H2 produced at 23°C and 4 atm:

V= \dfrac{nRT}{P}= \dfrac{(1.1\:\text{mol}\:H_2)(0.082\:\text{L-atm/mol-K})(296K)}{4\:\text{atm}}

=8.9\:\text L\:H_2

I need help asap!!!!
Butoxors [25]

Answer:

2H₂O₂ →  2H₂O + O₂

24.7 L are the liters of formed oxygen.

Explanation:

We state the reaction:

2H₂O₂ →  2H₂O + O₂

2 moles of peroxide decompose to 2 moles of water and 1 mol of oxygen gas.

We convert the mass to moles: 75 g . 1 mol / 34 g = 2.20 moles

As ratio is 2:1, per 2.20 moles of peroxide I would produce the half of moles, of O₂ → 2.20 /2 = 1.10 moles

We convert the moles to mass → 1.10 mol . 32 g / 1 mol = 35.3 g

Let's use oxygen's density to find out the volume

δ O₂ = 1.429 g/L    (mass/volume)

35.3 g . 1L / 1.429g = 24.7 L
