Akimi4 [234]3 years ago

The options for the given question are given below.

a) the location where there is zero probability of finding the electron

b) that the electron’s location can be precisely determined

c) that Heisenberg’s uncertainty principle is violated

d) the distance from the nucleus at which the electron is most likely to be found

Answer : The correct option is d "the distance from the nucleus at which the electron is most likely to be found"

Explanation :

The probability distribution curve is the plot of density function ( represented by y axis) vs the distance of electron from the nucleus ( represented by x axis).

The peak of the curve shows the maximum density of finding an electron. The corresponding value on x axis therefore represents the distance at which this maximum density can be located.

Therefore we can say that the peak of a probability curve for an electron in an atom indicate the distance from the nucleus at which the electron is most likely to be found.

A scientist measures the standard enthalpy change for the following reaction to be -327.2 kJ : P4O10(s) 6 H2O(l)4H3PO4(aq) Based
OleMash [197]

Answer:

ΔH°f P4O10(s) = - 3115.795 KJ/mol

Explanation:

  • P4O10(s) + 6H2O(l) ↔ 4H3PO4(aq)
  • ΔH°rxn = ∑νiΔH°fi

∴ ΔH°rxn = - 327.2 KJ

∴ ΔH°f H2O(l) = - 285.84 KJ/mol

∴ ΔH°F H3PO4(aq) = - 1289.5088 KJ/mol

⇒ ΔH°rxn = (4)(- 1289.5088) - (6)(- 285.84) - ΔH°f P4O10(s) = - 327.2 KJ

⇒ ΔH°f P4O10(s) = - 5158.035 + 1715.04 + 327.2

⇒ ΔH°f P4O10(s) = - 3115.795 KJ/mol

A patient needs 40.0 mg of antibiotic per kilogram of body weight each day. If the patient weighs 55 kilograms.
White raven [17]

2200 mg of antibiotic

Explanation:

Given that 40 mg of antibiotic/kg of the bodyweight is given.

If patient is 55 kg then  the dose of antibiotic will be

if 40/1000000 is done then we can get antibiotic in kg/kg of the weight

= 0.00004 kg of antibiotic per kg

0.00004*55 ( to know how much 55 kg person will require)

= 0.0022 kg

This 0.0022 value will be converted to mg

0.0022*10^6

= 2200 mg of antibiotic will be given to a 55kg patient.
