Answer:

The correct answer is B. Less developed countries do not have access to safe and reliable family-planning and health care as do more developed countries.

Explanation:

In general, less developed countries have higher population growth rates than developed countries do. This is because these countries lack developed medical centers capable of guiding their populations in terms of family planning, which means that pregnancy rates are higher due to ignorance and lack of availability of contraceptive methods. Likewise, these countries have high mortality rates, with which life expectancy tends to be lower than that of developed countries; This is also explained in the deficiencies of their health systems.

Explain why the standard enthalpy of formation () for Cl2 (g) is zero, but its standard entropy is larger than zero.
Galina-37 [17]

The standard enthalpy of formation for chlorine is zero but the standard entropy is larger than 0 because it is the elemental state of chlorine.

The standard enthalpy of formation for chlorine is zero because cl2 is the elemental state of chlorine and it does not require any energy for the formation of the standard state of chlorine.

The entropy of any system cannot be negative. It can only be positive or zero.

The entropy of a system will become zero only at a absolute zero temperature.

That's why the entropy of chlorine in elemental state is more than zero because absolutely zero temperature can't be obtained.

What is the volume, in liters, of 5.500 mol of C3H3 gas at STP
ZanzabumX [31]

Answer:

123.2 Liters.

Explanation:

At STP (T = 273K & P = 1atm)<em>, one mol of any gas will occupy 22.4 liters</em>.

With the above information in mind, we can <u>calculate how many liters would 5.500 mol of gas occupy</u>:

5.500 mol * 22.4 L / mol = 123.2 L

So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

The gene for tallness (T) in a pea plant is dominant over the gene for shortness (t).
astra-53 [7]

Answer:

C. 75%

Explanation:

From a heterozygous cross (Tt x Tt) the produced offspring would consist of:

  • 25% TT -it would be tall-.
  • 50% Tt -it would be tall as the gene T is dominant-.
  • 25% tt -it would not be tall-.

Thus the produced offspring that would be tall is (50% + 25%) 75%. The answer is option C.
