Answer:indirect causes of disease include genetics, lifestyle, and environmental factors

Explanation:

The indirect disease -causing factors include some genetic factors, infections from other persons etc. Thus options A ,C and D are correct.

There are some factors such as infection from other people make us infected also not by directly originating in ourselves. For example, passive smokers may have respiratory disorders.

Some disease can be generated indirectly from the gene types inherited from parents. These may cause imperfect gene coding and some times trigger cancer.

Infections such as flu, cold, different types of fevers, viral and bacterial infection are able to spread and might affect other two-three people.

Therefore, indirect disease -causing factors includes genetic disorders inherited from parents and infections from environment and hence options A, C and D are correct options.

Answer:

A. Li-O

Explanation:

The highest polarization will occur between the atoms of  Li-O because they have the most electronegativity difference between them.

Polarization occurs when there is a separation of charge between the atoms of heteronuclear molecules.

The electronegativity gives the tendency for an atom to attract the electrons within the bond pair to itself.

To know the atom with most polarization, it has to be one with highest electronegativity difference. Li and O have the highest difference. Also, since the bond is between a metal and non-metal, it is obviously the most polarized.

Answer:

The Outer-most Electron shell contains the valence electrons.

Bonus Info:

Valence Electrons are used by atoms to make ionic bonds.

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

the empirical formula for this compound

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.

The empirical formula also shows the simplest mole ratio of the constituent elements of the compound

mol of element A :

[tex]\tt mol=\dfrac{mass}{Ar}\\\\mol=\dfrac{3.5}{7}=0.5[/tex]

mol of element G :

[tex]\tt mol=\dfrac{4}{16}=0.25[/tex]

mol ratio A : G = 0.5 : 0.25 = 2 : 1

Answer:

The pressure of N₂ gas in cylinder B when compressed at constant temperature increases due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container.

Explanation:

Gas helps to explain the behavior of gases when one or more of either temperature, volume or pressure is varying while the other variables are kept constant.

In the gas cylinder B, the temperature of the given mass of gas is kept constant, however, the volume is decreased by pushing the movable piston farther into the cylinder. According to the  gas law by Robert Boyle, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature. This increase in pressure is due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container. As the cylinder becomes smaller, the gas molecules which were spread out further become more packed closely together, therefore, their frequency of collision increases building up pressure in the process.

In terms of collisions between gas molecules and the walls of the container, the reason why pushing the movable piston farther into cylinder B at constant temperature would increase the pressure of the N2 gas is due to the fact that;

Chemical

Explanation:

Answer:

1.75m/s or 6.3km/hr

Explanation:

here,

acceleration (a) = 0.7m/s^2

mass (m) = 30g

time (t) = 2.5s

initial velocity (u) = 0m/s

final velocity (v) = ?

now,

v = u + at

or, v = 0 + 0.7 * 2.5

hence, Final velocity (v) = 1.75 m/s

if u want to convert to km/hr

then,

1.75 * 3.6 (we know that 1m/s = 3.6km/hr)

= 6.3km/hr
