Answer:

\huge \boxed{\mathrm{C) \ 1, 2,2,1}}

\rule[225]{225}{2}

Explanation:

\sf CH_4+ O_2 \Rightarrow CO_2 + H_2O

Balancing the Hydrogen atoms on the right side,

\sf CH_4+ O_2 \Rightarrow CO_2 +2 H_2O

Balancing the Oxygen atoms on the left side,

\sf CH_4+ 2O_2 \Rightarrow CO_2 +2 H_2O

\rule[225]{225}{2}

Answer:

B

Explanation:

CH4 + O2 →H2O + CO2

Left side

C = 1

H = 4

O = 2

Right side

C = 1

H = 2

O = 3

So find common denominator in this case would be 6 O

CH4 + 3O2 →2H2O + CO2

Left side

C = 1

H = 4

O = 6

Right side

C = 1

H = 4

O = 6

What is the Golden Rule of Solubility? A. polar dissolves nonpolar. B. nonpolar dissolves polar. C. like dissolves unlike D. lik
DerKrebs [107]

Answer: D. like dissolves like

Explanation:

The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Hydrocarbons are non polar in nature due to less difference between the electronegativities of carbon and hydrogen and thus are soluble in non polar solvents only.

Ionic compounds which are formed by elements with high electronegativity difference are polar in nature and thus dissolve in polar solvents.

Example: NaCl in water.

In the reaction K2CrO4 (aq) + PbCl2 (aq) 2KCl (aq) + PbCrO4(s), how many grams of PbCrO4 will precipitate out from the reaction
pashok25 [27]
Reaction equation:
K₂CrO₄(aq) + PbCl₂(aq) → 2KCl(aq) + PbCrO₄(s)

Concentration = moles / Liter
moles(K₂CrO₄) = 3 x 0.025
= 0.075

By the equation, we see that the molar ratio of
K₂CrO₄ : PbCrO₄ is
1 : 1
moles(PbCrO₄) = 0.075

mass = moles x Mr
mass = 0.075 x (207 + 52 + 16 x 4)

mass = 24.2 grams

What is the density of a gas with a molar mass of 28.26 grams per mole at 3.510 ATM in 237 Kelvin​
Vikki [24]
<h3><u>Answer;</u></h3>

= 5.1 g/L

<h3><u>Explanation;</u></h3>

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Number of moles is 1 since one mole has a mass equivalent to the molar mass.

Therefore; We can find the volume and thus get the density.

<em>V = nRT/P</em>

<em>    = (1 × 0.08206 × 237)/3.510</em>

<em>     = 5.5408 L</em>

<em>Hence; Density = mass/volume </em>

<em>                           = 28.26 g/5.5408 L</em>

<em>                           = 5.1 g/L</em>

<em>The Density is 5.1 g/L or 0.005 g/cm³</em>
