Answer:

Water spit occurs during release of hydrogen ions,electrons and oxygen.

Explanation:

During photosynthesis,water is required to be occured.The light activated the chlorophyll during light reactions,This activated chlorophyll molecule will results in splitting of water molecules,as a result water splits into hydrogen,oxygen and electrons.This process is known as photolysis.Hence water splitting occurs during light dependent reactions in release of hydrogen ions,electrons and oxygen.

Luke and Sian want to plant a vegetable garden in their yard. A soil testing kit measures the soil pH at 5.0, but the lettuce th

dexar [7]

Answer:

So, Luke and Sian has to increase the pH of the soil by adding base to it.

Explanation:

The pH is defined as the negative logarithm of the hydrogen ion concentration in their aqueous solution.

$pH=-\log[H^+]$

With increase in hydrogen ion concentration the pH value decreases.
With decrease in hydrogen ion concentration the pH value increases.

The pH of the soil after testing it on a kit comes out be 5.0, but they both need pH of the soil to 6.5.

Comparison of pH of soil:

= 5.0 < 6.5

= High hydrogen ion concentration > High hydrogen ion concentration

So, Luke and Sian has to increase the pH of the soil by adding base .Doing so will decrease the hydrogen ion concentration in the soil (where as addition of acid lower the pH of soil).

Which of the following substances is most likely to be a liquid at room temperature?

nikitadnepr [17]

Answer:

The correct answer is d.hydrogen peroxide H₂O₂H₂O₂

Explanation:

Substances can be found in nature in different aggregation states. 

Agreggation states can be liquid, gas or solid.

The problem asks about which substance can be found in room temperature as liquid. Each subtances has different physical and chemical properties that determines in which state you can find them at room temperature.

Hydrogen peroxide is the only substance listed that is in liquid state at room temperature, all other substances are in gas state at room temperature.

Refraction occurs when the speed of light changes as it travels between mediums. T F

Mariana [72]

The answer is true

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light.The wavelength decreases as the light enters the medium and the light wave changes direction.
