Determine the name for aqueous H2CO3. carbonous acid dihydrogen carbonate carbonic acid hydrocarbonic acid hydrocarbide acid
BabaBlast [244]

The name for aqueous H_{2} CO_{3} is carbonic acid.

So, option C is correct one.

Binary hydrogen compounds with non metals may form H+ (proton) and an anion dissolved in water. The acidic solutions are named as if they were molecular acids , using the usual name for the compound itself , replacing hydrogen with hydro- and suffix -ide with ic. The word acid is then use.

The inorganic acid is an acid drive from one or more inorganic compounds. All inorganic acids form hydrogen ions and the conjugate base ions when dissolved in water.

Example: carbonic acid ( H_{2} CO_{3} )

A gas is collected in a 34.3L container at a temperature of 31.5°C. Later, the container has a volume of 29.2L, a temperature of
goldenfox [79]

Answer:

108 kPa  

Step-by-step explanation:

To solve this problem, we can use the <em>Combined Gas Laws</em>:

p₁V₁/T₁ = p₂V₂/T₂             Multiply each side by T₁

   p₁V₁ = p₂V₂ × T₁/T₂      Divide each side by V₁

      p₁ = p₂ × V₂/V₁ × T₁/T₂

Data:

p₁ = ?;                 V₁ = 34.3 L; T₁ = 31.5 °C

p₂ = 122.2 kPa; V₂ = 29.2 L; T₂ = 21.0 °C

Calculations:

(a) Convert temperatures to <em>kelvins </em>

T₁ = (31.5 + 273.15) K = 304.65 K

T₂ = (21.0 + 273.15) K = 294.15 K

(b) Calculate the <em>pressure </em>

p₁ = 122.2 kPa × (29.2/34.3) × (304.65/294.15)  

   = 122.2 kPa × 0.8542 × 1.0357

   = 108 kPa

Given that a 11.00 g milk bar chocolate bar contains 7.500 g of sugar, calculate the percentage of sugar present in 11.00 g of m
alukav5142 [94]

Answer:

68.18%

Explanation:

The question asking for the percentage of sugar present in milk bar chocolate. To find the percentage of a certain molecule, you have to divide the mass of the molecule with the total mass of the product. The calculation will be:

sugar percentage = sugar weight / milk bar chocolate weight * 100%

sugar percentage = 7.5g / 11g * 100%= 68.18%

Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and
Vaselesa [24]

The number of  kilograms  of fuel   that are contained in one  canister  is 1.03 Kilograms


calculation

mass =  density x  volume

Density= 0.710 g/cm³

volume = 1.45 L

convert  1.45 l into cm³  to make the units  uniform

that is     1 L= 1000 cm³

              1.45 L=  cm³

by cross  multiplication

= (1.45 L  x 1000 cm³)  / 1 L  = 1450 cm³


mass is therefore =   0.710g/cm³  x 1450 cm³   =1029.5 grams


convert grams to Kg

1 kg = 1000 grams

  ? kg  =1029.5  grams

by cross  multiplication

= (1 kg  x 1029.5 grams) /1000 grams  = 1.0295 Kg ≅1.03 kg

Ground level ozone is created when sunlight reacts with certain chemicals that come from sources of burning fossil fuels, such as factories or car exhaust. When particles in the air combine with ozone, they create smog. Smog is a type of air pollution that looks like smoky fog and makes it difficult to see. Additionally, Cities located in basins surrounded by mountains may have smog problems because the smog is trapped in the valley and cannot be carried away by wind
