The possible negative health effects of television viewing on children and adolescents are violent or aggressive behavior by watching violent films, increase sexual activity, increase in weight, poor body image. Watching more television waste time as well as decreased school performance. The adolescents stay away from physical activities such as sports and outdoor games. While watching TV is not an "evil" thing, it can have some affects in the youth. It can affect behavior with friends, family and other people whom are around you. In addition it could even go as far as affecting academic success and failure. Watching television can interfere with time the adolescents could be using to study or spend time outdoors. It also could show images that would not be appropriate for an adolescent to view. Overall, while television is not evil, and can be an entertaining pasttime, it can affect adolescents negatively.

I believe the ans is (2) pH = 7.

Explanation:

At the equivalence point, the salt of strong acid and strong base is completely hydrolyzed which gives a neutral solution with pH 7 as H+ ion concentration is equal to OH- ion concentration.

Answer:

1257.03 grams

Explanation:

mass=mole*molar mass

mass=7.4*169.87= 1257.03

Answer:

3200

Step-by-step explanation:

Let the number be x:

25 % of x = 800

⇒ 25/100 × x = 800

⇒ 1/4 × x = 800

⇒ x = 800 × 4

∴ x = 3200

Answer:

The reaction can produce 287 grams of iron(II) carbonate

Explanation:

To solve this question we must find the moles of iron(II) chloride that react. Using the chemical equation we can find the moles of iron(II) carbonate and its mass -Molar mass FeCO3: 115.854g/mol-

Moles FeCl2:

1.24L * (2.00mol / L) = 2.48 moles FeCl2

As 1 mol FeCl2 produce 1 mol FeCO3, the moles of FeCO3 = 2.48 moles

Mass FeCO3:

2.48mol * (115.854g / mol) =

Answer:

The Bronsted-Lowery acid is H2O

The Bronsted-Lowery base is CO3

The conjugate acid is HCO3

The conjugate base is OH

Explanation:

Molocules that lose a hydrogen in a reaction act as an acid, and those that recieve one act as a base.

Answer:

D) C5H12

Explanation:

The rate of evaporation of a solution depends on the nature of intermolecular forces in the solution. The stronger the magnitude of intermolecular forces present the lower the rate of evaporation.

If we consider the compounds; C7H15OH, C7H15NH2 and C6H13COOH, the presence of polar groups implies that dipole-dipole interactions are present in the molecule leading to stronger intermolecular interaction and a slower rate of evaporation.

On the other hand; C7H16 and C5H12 are alkanes. The intermolecular forces that exists between their molecules is the weak dispersion forces. However, the magnitude of dispersion forces increases as the molecular mass of the compound increases.

Hence, C5H12 has the fastest rate of evaporation since it has the lowest molecular mass.

Answer:

the four major type of animal tissue are:

connective tissue

nervous tissue

epithelial tissue

muscular tissue

Answer: The options are not given, here are the options from another websites.

A. A +2, B +8

B. A +2, B -4

C.A +5, B +5

The correct option is C.

Explanation:

This is because there is sharing of charge between the two metal objects and are both positive. Normally when two positive objects come together, they repel each other. which means that positively charged object A will exert a repulsive force on the other positively charged object. The repulsive force that is created between them will push the two objects apart.

Answer:

the observation of the third option is correct one.

Answer:

Inverse relationship between number of covalent bonds and bond length.

Explanation:

There is inverse relationship between number of covalent bonds and bond length which means that if one increases the decreases or the one decreases the increases. When the number of covalent bonds between two atoms increases, the bond length decreases because there are more number of electrons present between the two nuclei, the two nuclei can get closer to each other until both nuclei experience their repulsive force of attraction. In bond of H2S has lower electronegativity value as compared to H2O so the bond length decreases due to attraction of shared pair of electrons by both nuclei.

The greenhouse effect refers to global warming as a consequence of the accumulation of greenhouse gases.

Greenhouse gases are different types of gaseous elements that trap solar radiation on the Earth's surface.

The most important greenhouse gases include, among others, methane and carbon dioxide (CO2).

In conclusion, the greenhouse effect refers to global warming as a consequence of the accumulation of greenhouse gases.
