CO2(g) + H2O(I) - -> C6H12O6(s) + O2(g)

Chemistry

Lana71 [14]3 years ago

4 0

Answer:

For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are enter reagents only and click 'Balance'. In many cases a complete equation will be suggested.

What are alkenes used to make?

evablogger [386]

Answer:

By far the most important use of alkenes is in the making of plastics as plastics are used in almost everything.

Explanation:

Alkenes themselves aren't used much in everyday life however Alkenes are very important to industrial synthesis as it is relatively easy to turn them into other things.

Alkenes can be turned into polymers or plastics through addition reactions and the most common ethene is turned into everything from plastic bags to bottles.

Alkenes can also be turned into alcohols. most commonly propene is used as a feedstock to produce butanol and other products useful in industry or for production

In the atmosphere, it is more common to find two oxygen molecules joined together than to find a single atom of oxygen. Why? Wha

VLD [36.1K]

Answer:

See explanation

Explanation:

Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.

In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.

An image of the oxygen molecule is attached to this answer.

This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).

Predict the sign for AS for each of the following systems: Water freezing Water evaporating Crystalline urea dissolving Assembly

djyliett [7]

Answer: 1. Water freezing : $\Delta S$ is -ve.

2. Water evaporating : $\Delta S$ is +ve.

3. Crystalline urea dissolving : $\Delta S$ is +ve.

4. Assembly of the plasma membrane from individual lipids: $\Delta S$ is -ve.

5. Assembly of a protein from individual amino acids: $\Delta S$ is -ve.

Explanation:

Entropy is defined as the measurement of degree of randomness in a system.

It is represented by symbol S and we can only measure a change in entropy which is given by $\Delta S$ .

If there is decrease in randomness , the sign for $\Delta S$ is -ve and If there is increase in randomness , the sign for $\Delta S$ is +ve.

1. Water freezing: Entropy decreases as we move from liquid state to to solid state and thus $\Delta S$ is -ve.

2. Water evaporating : Entropy increases as we move from liquid state to gaseous state and thus $\Delta S$ is +ve.

3. Crystalline urea dissolving : The molecules convert from solid and ordered state to aqueous phase and random state. Thus the entropy increases and thus $\Delta S$ is +ve.

4. Assembly of the plasma membrane from individual lipids: random lipids are associating to form a single large polymer and thus entropy decreases and thus $\Delta S$ is -ve.

5. Assembly of a protein from individual amino acids: random amino acids are associating to form a single large polymer and thus entropy decreases and thus $\Delta S$ is -ve.
