How would you measure the pH of a coloured substance such as red ink.why?

Answers

Answer 1

Answer: There are 3 possible ways of determining pH.
1. A pH meter, 2. Litmus paper/ pH test strips or 3. Titrations.

1. A pH meter works by sending a small electric current through the solution. An electrical current can only be created if there are free-moving particles such as H+ ions from an acid or OH- ions from a base. The pH meter can determine the pH by how high the conductivity is.

2. Litmus Paper or pH test strips are strips that turn a specific colour under a specific pH. This colour can then be compared to a colour chart which will tell you the pH. The downfall of this method is that the red ink will stain the strip and you will be unable to get an accurate reading.

3. A titration is the best method, if done properly, for determining pH.

Which processes result in the release of carbon? Select three options.Animals break down food molecules to obtain energy.
The remains of producers are broken down by decomposers.
The remains of consumers are broken down by soil decomposers.
Producers take in carbon dioxide.
Producers make sugars and starches.

Answers

The three processes that releasecarbon are as follows:

Animals break down food molecules to obtain energy.

The remains of producers are broken down by decomposers.

The remains of consumers are broken down by soil decomposers.

Carbon moves back and forth from living organisms to the atmosphere in a process summarized by CARBON CYCLE. In the carbon cycle, carbon is either absorbed or released in series of processes.

WAYS THROUGH WHICH CARBON IS RELEASED:

Animals break down food molecules to obtain energy in a process called CELLULAR RESPIRATION. Carbon is released into the atmosphere in form of carbon dioxide (CO2).

The remains of producers (plants) are broken down by decomposers (fungi, bacteria etc). Carbon is returned back to the soil this way.

The remains of consumers, when they die, are broken down by soil decomposers (fungi, bacteria).

Explain the relationship between societyand the technologies of using Earth's
resources.

Answers

Technology is built to give means, tools, and machinery for the preservation of the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials, which is how technology and the environment are interdependent.

What is global warming ?

The gradual increase in the planet's surface temperature is known as global warming. Although this warming trend has been around for a while, the burning of fossil fuels has greatly accelerated its pace over the past century. The amount of fossil fuels burned has increased along with the size of the human population.

The two main ways that these technologies have harmed our planet are through pollution and the depletion of natural resources. When dangerous or excessive levels of gases like carbon dioxide, carbon monoxide, sulfur dioxide, nitric oxide, and methane are released into the earth's atmosphere, air pollution results.

Technology and society have a reciprocal interaction. Technological advancement shapes society, while technological advancement drives it.

Thus, the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials.
