Wait wait wait, did you mistype your question? Water and water would just mix together, agar is thicker than water.

Draw the carboxylic acid produced from the acid hydrolysis of butyl acetate.

Nat2105 [25]

Answer:

Acetic or ethanoic acid.

Explanation:

Hello,

Butyl acetate's hydrolisis is shown below:

$CH_3COOCH_2CH_2CH_2CH_3+H_2O-->CH_3COOH+CH_3CH_2CH_2CH_2OH$

Whereas $CH_3COOCH_2CH_2CH_2CH_3$ is the butyl acetate, $CH_3CH_2CH_2CH_2OH$ butanol and $CH_3COOH$ the required produced acid, acetic or ethanoic acid (attached picture).

Best regards.

Answer:

6.82 moles of Fe2O3

Explanation:

Step 1:

Determination of the number of mole of in 450g of CO2.

This is illustrated below:

Molar Mass of CO2 = 12 + (2x16) = 44g/mol

Mass of CO2 = 450g

Number of mole of CO2 =.?

Number of mole = Mass/Molar Mass

Number of mole of CO2 = 450/44 = 10.23 moles

Step 2:

Determination of the number of mole of Fe2O3 needed for the reaction. This is illustrated below:

2Fe2O3 + 3C—> 4Fe + 3CO2

From the balanced equation above,

2 moles of Fe2O3 reacted to produce 3 moles of CO2.

Therefore, Xmol of Fe2O3 will react to produce 10.23 moles of CO2 i.e

Xmol of Fe2O3 = (2x10.23)/3

Xmol of Fe2O3 = 6.82 moles

Therefore, 6.82 moles of Fe2O3 is required.

What is the total number of nitrogen atoms in two mol of NH4NO3 ?

Fynjy0 [20]

Answer:

2.409 x 10²⁴

Explanation:

There are two nitrogens for every mole of NH₄NO₃

Since there are two moles, that means there are 4 nitrogens

There are 6.022 x 10²³ atoms in every mole of any element

(6.022 x 10²³) x 4 = 2.4088 x 10²⁴

Use sig figs to round it to 2.409 x 10²⁴

Answer:

2.Closed System: A closed system is a thermodynamic system where energy can be exchanged with its surrounding but not matter. Open System: Open systems can exchange matter with the surrounding. Closed System: Closed systems cannot exchange matter with the surrounding. Open System: The mass of the system will vary with time in open systems.

Explanation:

1.The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and steam look the same because they are all water, but in different states of matter. Why do we use the particle model in science?

3.An open system can be defined as a system which can exchange both matter and energy with the surrounding. For example, the earth can be recognized as an open system. In this case, the earth is the system, and space is the surrounding. Sunlight can reach the earth surface and we can send rockets to space.
