The correct answer is e) atom A becomes a positive ion and atom B becomes a negative ion. Ions are charged particles that result when a neutral atom gains or loses an electron.

Further Explanation:

In a neutral atom, the number of protons is equal to the number of electrons.In a positive ion, the number of protons is greater than the number of electrons.In a negative ion, the number of protons is less than the number of electrons.

In the problem, atom A loses an electron to atom B.

Suppose atom A has 11 protons and 11 electrons and atom B has 9 protons and 9 electrons.

BEFORE TRANSFER OF ELECTRONS

atom A: 11 protons, 11 electrons

atom B: 9 protons, 9 electrons

AFTER TRANSFER OF ELECTRONS

atom A: 11 protons, 10 electrons

atom B: 9 protons, 10 electrons

a) atom A becomes a negative ion and atom B becomes a positive ion FALSE because atom A has more protons than electrons turning it into a positive ion, and atom B now has more electrons making a negative ion.

b) atom A acquires more neutrons than atom B FALSE because only the number of electrons changed. The number of neutrons are unchanged in the formation of ions.

c) atom A becomes more negative than atom B FALSE because atom A becomes more positive since there is more protons (positively charged) than electrons (negatively charged) while atom B, with its extra electron becomes negatively charged

d) atom A acquires less neutrons than atom B FALSE because the number of neutrons does not change. Only an electron was transferred.

e) atom A becomes a positive ion and atom B becomes a negative ion TRUE because there are more protons than electrons in A after the electron transfer and there are more electrons in B than protons after receiving the electron.

the moving of the box is a result of centripetal force. think of that as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.

We want to calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. the air temperature is 20 oc, canaryâ€™s body internal and surface temperature is 33oc, external body surface convective heat transfer coefficient is 25.2 w/m2 .k, temperature difference between the inhaled and exhaled air is 4.3 oc, the ventilation rate is 0.74 cc of air per second, specific heat of air is 1.0066 kj/kg.k and density of air is 1.16 kg/m3 . assume the canaryâ€™s body to be a cylinder with 7 cm diameter and 9 cm length, and heat exchange is from the side as well as the top and bottom of cylinder. calculate 1) the net rate of heat lost by radiation, assuming heat gained by the bird through radiation from the surroundings is 11.5 w; 2) rate of heat transferred by convection to the surrounding air; 3) rate of heat transferred in the exhaling air without considering any internal evaporation; 4) total metabolic power.
