The type of reaction that occur when (CH4) burns in oxygen to produce carbon dioxide and water is combustion reaction

explanation

Combustion reaction is type of chemical reaction in which a compound and oxidant react to produce heat and new product.

when a hydrocarbon for example methane undergoes combustion it produces carbon (iv) oxide, water and heat according to reaction below.

CH4 + 2O2 → CO2 + 2H2O + heat

Acetic acid (CH3CO2H) is the principal component in the vinegar. What is the molarity of an acetic acid solution if a titration

Alexxx [7]

Answer : The molarity of an acetic acid solution is, 0.0338 M

Explanation :

Formula used :

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of acetic acid.

$M_2\text{ and }V_2$ are the molarity and volume of NaOH.

We are given:

$M_1=?\\V_1=50.0mL\\M_2=0.0567M\\V_2=29.80mL$

Putting values in above equation, we get:

$M_1\times 50.0mL=0.0567M\times 29.80mL\\\\M_1=0.0338M$

Hence, the molarity of an acetic acid solution is, 0.0338 M

At 800 K, the equilibrium constant, Kp, for the following reaction is 3.2 × 10–7. 2 H2S(g) ⇌ 2 H2(g) + S2(g) A reaction vessel a

djverab [1.8K]

Answer:

0.008945 atm

Explanation:

In the reaction:

2H2S(g) ⇌ 2 H2(g) + S2(g)

Kp is defined as:

$Kp = P_{H_{2}}^2P_{S_{2}} / P_{H_{2}S}^2$

Where P is the pressure of each compound in equilibrium.

If initial pressure of H2S is 3.00atm, concentrations in equilibrium are:

H2S = 3.00 atm - 2X

H2 = 2X

S2: = X

Replacing:

$3.2x10^{-7} = (2X)^2X / (3-2X)^2$

$3.2x10^{-7} = 4X^3 / 9- 6X+4X^2$

0 = 4X³ - 1.28x10⁻⁶X² + 1.92x10⁻⁶X - 2.88x10⁻⁶

Solving for X:

X = 0.008945 atm

As in equilibrium, pressure of S2 is X, pressure is 0.008945 atm

How does dipping an iron bucket in Molten zinc protect it?

Zigmanuir [339]

Answer:

It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc. The zinc protects its base metal by corroding before iron.
