a solution is an acid or base and it doesn't react with metal. is it pH more likely to be 4 or 9? explain your answer

1 answer:

6 0

It is more likely 9. pH 4 is acidic and pH 9 is basic, and as the pH of a substance gets closer to 0 or 14, the substance becomes more corrosive or reactive. As 4 is closer to 0 than 9 is to 14, there is a much higher chance the solution has a pH of 9, because pH 4 is less neutral and therefore more corrosive/reactive than pH 9.

STatiana [176]

Some areas of the Earth receive more solar radiation than others and this Sun’s uneven heating of the Earth result in 

i. Climate

ii. Weather

iii. Ocean currents

Further Explanations:

Earth receives varied amount of solar radiation in its different parts. The situation is due to the orbicular shape of the Earth and inclination of the sun during different time of the year. We can see one such example that, during June sun is overheard Tropic of cancer and during September it is overhead Tropic of Capricorn. Because of the inclination,different regions of the Earth experience different climate at the same span of time. This unevenness results in the following phenomenon:

i. Climate:Climate is a continuing average weather condition of a place. Some of the climatological variables commonly measured to determine the climate temperature, moistness, atmospheric pressure, current of air, and precipitation.

ii. Weather: It is defined as the state of atmosphere, describing the degree of heat or coldness, wetness or aridness, calm or stormy. It also refers to daily temperature and rainfall activities.

iii. Ocean Current: It is more or less perpetual or continuous engaged movement of oceanic water flowing on the Earth’s oceans. The current gets created as the resultant of geological forces acting on the oceanic surface.

<h3>What is a model?</h3>

A model is a representation of reality. We use models to understand what the real situation of things is like.

Let us recall that plants are the producers in the ecosystem. Energy flow from plants to animals. Plants obtain energy via the reaction 6CO2 + 6H2O --->C6H12O6 + ATP. This energy is passed along the food chain as organisms feed on each other.
