A. the polarity of the water molecule because the balloon is negatively charged and the positive hydrogen end of the water molecules are attracted to it

Fofino [41]3 years ago

Answer is A. The polarity of the water molecule

Water is a polar molecule due to an uneven distribution of electron density. Water has a partial negative charge near the oxygen atom and partial positive charge near the hydrogen atoms. Thus, dipole moment is created when there is a charge separation between the molecules. The dipole moment of water is 1.85. Therefore, when the charged balloon is placed close to the stream of water, it cause all the molecules of water to bend towards the balloon which has static charge on it.

What are the negative consequences of improper disposal of electronic waste?​
Gre4nikov [31]

Answer:

1) Increased probability of hazardous chemical contamination.

2) Air, water, and soil pollution.

3) Mortality in both terrestrial and aquatic organisms.

4) Development of diseases in humans.

Explanation:

The improper disposal of electronic waste can have detrimental consequences for the environment and, as a result, to all living beings including humans.

If electronic waste is thrown away in an open area, it warms up and releases hazardous chemicals that are detrimental for the health of living beings. This occurs because <u>electronic objects contain toxic chemicals such as lead, mercury, cadmium, amongst others</u>.

These chemicals will eventually enter both soil and water, harming thousands to millions of terrestrial and aquatic organisms. Moreover, these chemicals will enter the food chain and, as humans consume these affected organisms, we are also affected in numerous ways. For example, ingesting these chemicals could cause reproductive issues, damage to both the nervous and digestive systems, the development of cancer, etc.

What is the main function of environmental policy? a. prevent the use of natural resources b. reduce human impact on the environ
Sergeeva-Olga [200]

The most important function of the environmental policy is to keep a track of human activities that can impact the environment.

Further explanation:

The environmental policy is a set of rules and regulations, laws, and policies made up by the government or organization regarding environmental issues. Ecosystem management, biodiversity maintenance, and water and air pollution are some of the issues concerning the environment. The policies which involve regulation of substances like pesticides and other industrial wastes also come under environmental policy. One of the most deliberate roles of environmental policy is to regulate and direct human activities so as to prevent the environment and its resources from the harmful effects. These policies also make sure that humans are not affected by the harmful changes in their environments.

The government intervention through policies for the protection of the environment is necessary as natural resources are not owned by any one person and tend to be over-exploited. When the waste products are produced by the factor along with the main product, it is released into the nearby water body, thereby leaving it contaminated. This water might be used by other people for drinking purposes but due to the contamination the society has to bear the extra cost of cleaning the water. Therefore, the environmental policy has provision which states that the dumping of factory waste must be done only when it is free of any hazardous chemicals. Another problem is that the common people have the incentive to utilize natural resources to any extent. With the least interference from the government the resources will be overused.

What is the mass of an atom with seven neutrons and eight electrons
Mrrafil [7]

Answer:

15 AMU, or 15 daltons.

Explanation:

Typically the number of protons matches that of the electrons. So, there's 8 protons and 7 neutrons. The 8 electrons have a total mass of 8/1000 AMU, not significant enough to be counted. So the total mass is 15 AMU.
