When the water inside a living cell freezes, the ice crystals damage the cell. The wood frog is a unique creature that can survi

ve being frozen. In extremely cold
conditions, the frogs liver produces large amounts of glucose (C6H12O6), which becomes concentrated in the frog's cells. How does the glucose help prevent ice

from forming in the frogs cells?

A)The added glucose dissociates and creates faster moving molecules.

B) The added glucose lowers the vapor pressure relative to the pure solvent.

C) The added glucose requires more energy which warms the frog

D)The added glucose lowers the freezing point of the solution within the frog's cells.

The fuel used in many disposable lighters is liquid butane, C4H10
Charra [1.4K]

Answer:

1.45 *10^23 atoms C

Explanation:

3.50 g butane * 1 mol butane/58.1 g butane =0.06024 mol butane

in 1 mol C4H10           -------- 4 mol C

in 0.06024 mol C4H10 -------- 4*0.6024 = 0.241 mol C

0.241 mol C * 6.02*10^23 atoms C/1 mol C = 1.45 *10^23 atoms C

4HCl + O2 ⇌ 2H2O + Cl2
Arada [10]

Answer:

The rate of forward reaction increases.

Explanation:

  • Le Châtelier's principle states that <em>when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

Increasing the volume of oxygen:

will increase the concentration of oxygen (reactants), so the equilibrium will be shifted to the right side (products side) to suppress the effect of increasing the volume of oxygen.

<em>So, the right choice is: The rate of forward reaction increases. </em>

An oceanographer went into the ocean to measure the salinity at different areas. Where would you expect the oceanographer to fin
grigory [225]

Due to high evaporation rate and low precipitation, the oceanographer to find the highest salinity at the tropics.

<h3>What is salinity?</h3>

Salinity refers to the salt content of a water body such as rivers and oceans.

Oceans and seas have high salinity due to the presence of many dissolved minerals.

Different area of the oceans have different salinities.

Salinity is highest at the tropics and equator due to high rate of evaporation and low precipitation.

Therefore, the oceanographer to find the highest salinityat the tropics.
