Alex Ar [27]

Answer:

b. 23.3g

Explanation:

Based on the reaction:

CH₄ + 2O₂ → CO₂ + 2H₂O

To find the mass of CO2 produced we must find, as first, the limiting reactant. With limiting reactant we can find the moles and the mass of CO2 as follows:

<em>Limiting reactant:</em>

For a complete reaction of 0.53 moles of CH4 are necessaries:

0.53 moles CH4 * (2mol O2 / 1mol CH4) = 1.06 moles O2.

As there are 1.5 moles, CH4 is limiting reactant.

<em>Moles CO2:</em>

1 mole of CH4 produce 1 mole of CO2. That means the moles of CO2 formed are 0.53 moles.

<em>Mass CO2 (Molar mass: 44.01g/mol)</em>

0.53 moles CO2 * (44.01g / mol) =

A liquid has a density of 1g/mL. If you have 50mL of the liquid, what would its mass be?
Svetlanka [38]

Answer:

<h2>The answer is 50 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of liquid = 50 mL

density = 1g/mL

The mass of the liquid is

mass = 50 × 1

We have the final answer as

50 g

PLZ ANSWER
Taya2010 [7]

Answer:

A. The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants.

Explanation:

In the carbon cycle image, the result of an industry's work releases carbon dioxide into the atmosphere (this is represented by the letter G), this carbon dioxide is stored in the atmosphere (letter C) and then absorbed by plants during the process. of photosynthesis (letter A).

The carbon cycle is constituted by the absorption of carbon dioxide by plants in the photosynthesis process. Half of this absorbed carbon is released into the atmosphere and the other half the vegetable uses to produce sugars (glycoses).  By ingesting the plants, the animals ingest together the carbon to their body, being released through respiration or decomposition. Because some fungi and bacteria are responsible for the decomposition of both animals and vegetables, they ingest part of this carbon, releasing it into the atmosphere and soil.  In addition to bacteria, the burning process also releases carbon dioxide into the soil and atmosphere. Vegetables, through the breathing process, also absorb carbon dioxide and release oxygen unlike animals.
