Which equation best represents the behavior of glucose in water?

Chemistry
1 answer:
poizon [28]2 years ago
8 0

Answer:

C6H12O6(s) -> C6H12O6(aq)

Explanation:

Glucose, C6H12O6, is a nonelectrolyte, so it will dissolve in water but will not dissociate at all. Strong electrolytes dissociate completely, weak electrolytes dissociate partially, and nonelectrolytes do not dissociate in water.

suppose a student poured equal volumes of water and naoh in two different flasks. he forgets to label his flasks and is confused
ArbitrLikvidat [17]

The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.

<h3>What is volume?</h3>

Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.

Volume is measures in litres.

When water is added to dilute acid like HCl, they become more dilute.

When NaOH is added to HCl, a neutralization reaction occurs.

The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.

The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

Copper has two naturally occurring isotopes. Cu−63 has a mass of 62.939 amu and relative abundance of 69.17%.
fiasKO [112]
The answer is 64.907 amu.

The atomic mass of an element is the average of the atomic masses of its isotopes. The relative abundance of isotopes must be taken into consideration, therefore:
atomic mass of copper = atomic mass of isotope 1 * abundance 1 + atomic mass of isotope 2 * abundance 2

We know:
atomic mass of copper = 63.546 amu
The atomic mass of isotope 1 is: 62.939 amu
The abundance of isotope 1 is: 69.17% = 0.6917
The atomic mass of isotope 1 is: x
The abundance of isotope 2: 100% - 69.17% = 30.83% = 0.3083

Thus:
63.546 amu = 62.939 amu * 0.6917 + x * 0.3083
63.546 <span>amu = 43.535 amu + 0.3083x
</span>⇒ 63.546 amu - 43.535 amu = 0.3083x
⇒ 20.011 amu = 0.3083x
   ⇒ x = 20.011 amu ÷ 0.3083 = 64.907 amu

Select the compound with the lowest lattice energy.
tatyana61 [14]

Answer:

A. CsBr(s)

Explanation:

we will get here compound with the lowest lattice energy

solution

As we know that Lattice energy is always proportional to the charge of ions and it is inversely proportional to the size of ions.

so that by the smallest charge and the largest size give us the lowest lattice energy and that charge and size is express as here as

Charge

Cs (+1), K(+1), Na (+1), Cl(-1), Br(-1), Sr(+2), Ca(+2), O(-2)     .......................1

and

Size

Na+ < Ca2+ < K+ < Sr2+ < Cs+, O2- < Cl- < Br-                ..........................2

so that here

correct answer is A. CsBr

How might cell division help multicellular organisms maintain and repair cells
Komok [63]
Because when the cells divide (resulting in more cells) the multicellular organism mantains its strong cells and when one cell is damaged the other cells compensate for that damaged cell.
