What caused the little puddle of water to appear under the syringe tip?​

Chemistry
1 answer:
Ghella [55]3 years ago
6 0

Answer:

he rise in the temperature from the sunlight results in the expansion of the water inside the syringe given the external temperature is higher than that of the fluid temperature. ... This is the reason for the little puddle of water to appear under the syringe tip after ten minutes in the sun.

D-Fructose is the sweetest monosaccharide. How does the Fischer projection of D-fructose differ from that of D-glucose? Match th
Aleks04 [339]

Answer:

aldehyde

carbon-1

ketone

carbon-2

Explanation:

Monosaccharides are colorless crystalline solids that are very soluble in water. Moat have a swwet taste. D-Fructose is the sweetest monosaccharide.

In the open chain form, monosaaccharides have a carbonuyl group in one of their chains. If the carbonyl group is in the form of an aldehyde group, the monosaccharide is an aldose; if the carbonyl group is in the form of a ketone group, the monosaccharide is known as a ketose. glucose is an aldose while fructose is a ketose.

In D-glucose, there is an aldehyde functional group, and the carbonyl group is at carbon-1 when looking at the Fischer projection.

In D-fructose, there is a ketone functional group, and the carbonyl group is at carbon-2 when looking at the Fischer projection.

How many atoms of sodium are in 3.80 mol of sodium, Na?
vova2212 [387]

Answer:

2.29 × 10²⁴ atoms Na

Explanation:

Step 1: Define

Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.

Step 2: Stoichiometry

3.80 \hspace{3} mol \hspace{3} Na(\frac{6.02(10)^{23} \hspace{3} atoms \hspace{3} Na}{1 \hspace{3} mol \hspace{3} Na} ) = 2.2876 × 10²⁴ atoms Na

Step 3: Simplify

We have 3 sig figs.

2.2876 × 10²⁴ atoms Na ≈ 2.29 × 10²⁴ atoms Na

What best describes the collisions between ideal gas molecules?
Serggg [28]

The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.

A student made a graph to show the chemical equilibrium position of a reaction.
pogonyaev

Answer:

Concentration, because the amounts of reactants and products remain constant after equilibrium is reached.

Explanation:

The rate of reaction refers to the amount of reactants converted or products formed per unit time.

As the reaction progresses, reactions are converted into products. This continues until equilibrium is attained in a closed system.

When equilibrium is attained, the rate of forward reaction is equal to the rate of reverse reaction, hence the concentration of reactants and products in the system remain fairly constant over time.

When deducing the rate of reaction, concentration of the specie of interest is plotted on the y-axis against time on the x-axis.
