The disease prevention methods are as follows:

Influenza: Avoid close contact with sick people; Cover your mouth and nose, Clean your hands
Salmonella: wash hands properly; keep food area clean; cook food properly
Type 2 Diabetes : exercise regularly; reduce sugar intake; quit smoking
HIV/AIDS: Avoid sharing of unsterilized sharp objects; avoid unprotected sex; screen blood before transfusion
Heart disease: avoid trans fat; exercise regularly; avoid smoking
Whooping cough: wear face masks; wash regularly; get vaccinated

<h3>What is the disease prevention?</h3>

Disease prevention refers to the steps taken to protect oneself from developing a particular disease.

The disease prevention methods for the given diseases is as follows:

Influenza: Avoid close contact with sick people; Cover your mouth and nose, Clean your hands
Salmonella: wash hands properly; keep food area clean; cook food properly
Type 2 Diabetes : exercise regularly; reduce sugar intake; quit smoking
HIV/AIDS: Avoid sharing of unsterilized sharp objects; avoid unprotected sex; screen blood before transfusion
Heart disease: avoid trans fat; exercise regularly; avoid smoking
Whooping cough: wear face masks; wash regularly; get vaccinated

In conclusion, disease prevention is the best policy in health care.

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object does not change. When the forces acting on an object are unbalanced, they do not cancel out one another. An unbalanced force acting on an object results in the object’s motion changing. The object may change its speed (speed up or slow down), or it may change its direction. Friction is a force that resists the motion or the tendency toward motion between two objects in contact with each other. Gravity is a force that pulls objects toward one another. For example, Earth pulls all objects toward it.

An exothermic reaction occurs spontaneously ,why?

Delvig [45]

Answer:

See below

Step-by-step explanation:

An exothermic reaction tends to occur spontaneously because the products are more stable than the reactants.

Nature tries to get to the lowest energy state.

What is the total number of outer (valence) electrons in carbon dioxide, co2? answer?

Anuta_ua [19.1K]

Carbon dioxide has a total of 16 valence electrons.

1. To determine the number of valence electrons of carbon dioxide (CO2), first determine the number of valence electrons of each of the elements in the molecule.

a. We have 1 carbon (C) molecule, and 2 oxygen (O) molecules.

b. The carbon molecule has 4 valence electrons and each oxygen molecule has 6 oxygen molecules.

2. Add up the valence electrons of each of the elements

4 + (2 x 6) = 16
(from C) (2 oxygen molecules, with 6 valence electrons each)

Thus, CO2 has a total of 16 valence electrons.

The number of valence electrons can be more clearly seen from the Lewis structure of the CO2 in the figure below (Source: http://chemistry.tutorvista.com/inorganic-chemistry/bonding-electrons.html). The the dots surrounding the letters represent the valence electrons.

Suppose you have a spherical balloon filled with air at room temperature and 1.0 atm pressure; its radius is 17 cm. You take the

Sladkaya [172]

Answer: 17.8 cm


Explanation:


1) Since temperature is constant, you use Boyle's law:


PV = constant => P₁V₁ = P₂V₂

=> V₁/V₂ = P₂/P₁

2) Since the ballon is spherical:

V = (4/3)π(r)³

Therefore, V₁/V₂ = (r₁)³ / (r₂)³


3) Replacing in the equation V₁/V₂ = P₂/P₁:

(r₁)³ / (r₂)³ = P₂/P₁

And you can solve for r₂: (r₂)³ = (P₁/P₂) x (r₁)³

(r₂)³ = (1.0 atm / 0.87 atm) x (17 cm)³ = 5,647.13 cm³

r₂ = 17.8 cm
