Meteorology is the scientific study of the atmosphere that focuses on weather processes and forecasting. Meteorological phenomena are observable weather events which illuminate and are explained by the science of meteorology. Those events are bound by the variables that exist in Earth's atmosphere.

The chief factors comprised by the science of meteorology are temperature, barometric pressure, humidity, sunlight and the interactions of each variable, as well as their variability. An example of meteorology would be the NOAA, who study the ocean and the atmosphere.

One of the intermediates in the synthesis of glycine from ammonia, carbon dioxide, and methane is aminoacetonitrile, C2H4N2.

mart [117]

Answer:

You could expect 3.48 grams of C₂H₄N₂

Explanation:

You must start by stating the chemical equation for the reaction of ammonia, carbon dioxide, and methane to produce aminoaceto nitrile.

1. Word equation:

Ammonia + Carbon dioxide + Methane → Aminoacetonitrile + Water

2. Balanced chemical equation:

$8NH_3+5CO_2+3CH_4\rightarrow 4C_2H_4N_2 +10H_2O$

3. Convert the mass of each reactant into number of moles:

Formula:

Number of moles = mass in grams/molar mass

2.11g NH₃

Number of moles = 2.11g / 17.03g/mol = 0.124 mol NH₃

14.9g CO₂

Number of moles = 14.9g/44.01g/mol = 0.339 mol CO₂

1.75g CH₄

Number of moles = 1.75g/16.04g/mol = 0.109 mol CH₄

4. Theoretical mol ratio

From the balanced chemical equation, using the coefficientes:

$8molNH_3:5molCO_2:3molCH_4:4molC_2H_4N_2:10molH_2O$

5. Limiting reagent

The available amounts of the reactants are:

0.124 mol NH₃

0.339 mol CO₂

0.109 mol CH₄

Fom the theoretical mole ration, to react with 0.124 mol of NH₃ you would need:

0.124molNH₃ × (5molCO₂/8molNH₃) = 0.0775 mol CO₂

Since there are 0.339 moles available, this is in excess.

0.124molNH₃ × (3molCH₄/8molNH₃) = 0.0465mol CO₂

Since there are 0.109 moles available, this is in excess too.

Hence, the limiting reagent is NH₃.

6. Yield

Use the theoretical ratio:

0.124molNH₃ × (4molC₂H₄N₂ / 8molNH₃) = 0.0620 mol C₂H₄N₂

Convert to grams:

Mass = number of moles × molar mass

0..0620 mol × 56.068g/mol = 3.48 g of C₂H₄N₂ ← answer

Select all that apply.

Ilya [14]

The definition of heat transfer through convection involves the movement of a fluid that causes heat to move away from a hear source. That being said, convection can take place in a lake, air inside, and air outside since both liquids and gasses are considered to be fluids. I hope this helps. Let me know if anything is unclear.

Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you t

marissa [1.9K]

Answer:

Sample A is a mixture

Sample B is a mixture

Explanation:

For sample A, we are told that the originally yellow solid was dissolved and we obtained an orange powder at the bottom of the beaker. Subsequently, only about 30.0 g of solid was recovered out of the 50.0g of solid dissolved. This implies that the solid is not pure and must be a mixture. The other components of the mixture must have remained in solution accounting for the loss in mass of solid obtained.

For sample B, we are told that boiling started at 66.2°C and continued until 76.0°C. The implication of this is that B must be a mixture since it boils over a range of temperatures. Pure substances have a sharp boiling point.

What is true about energy?

xeze [42]

The correct answer is option A. Energy cannot be created during an ordinary chemical reaction. There is no such thing as an ordinary chemical reaction. Energy cannot be created or destroyed this is according to the law of conservation of energy. It can only be transformed from one form to another form.
