Answer: In joules, Q = (47 kcal) (4186J/kcal) = 197 kJ. Since 47 kcal is released in the burning of 10 g of cookie, a 100-g portion would contain 470 food Calories, or 1970 kJ.
A sloth has both a scientific name and common name to help people know what creature they are. The scientific name is primarily used amongst scientists to understand which animal family they belong to and the common name is to help know what animal it is
<span>It’s
easier to determine the elecron configurations for the p-block elements
in periods 1,2,3 than to determine the electrons configurations for the
rest of the p-block elements in the periodic table beacause
from period 4, specifically from the element 31 (Ga), the atoms start to fill the d orbitals, and the energy levels of the 3d orbitals ara quite similar to the energy levels of 4p orbitals. So, for the elements Cr and Cu the right configurations do not match the configurations predicted using Aufbau method and Hund rules. Those are not the only exceptions but the two first. All is due to the proximity of the energy of the d and p orbitals and the fact that the rearrangement of the electrons result in a lower energy level. </span>
<span>(c) salt particles
</span>These salt particles are the type of condensation nuclei that are most likely to cause clouds to form. <span>Salt particles in the atmosphere provide a good non-gaseous surface where water vapor can transition into liquid. </span>
Germanium (Ge) is an element that has chemical behavior similar to that of silicon (Si) and lead (Pb). As it has an atomic mass greater than that of sulfur (S), but less than that of cadmium (Cd).
<h3>Why does the element of the same group have similar chemical behavior?</h3>
The chemical behavior of elements depends on the number of valence electrons in their outermost shell. Elements placed in the same group have the same number of valence electrons. Therefore, elements placed in the same group of the periodic table have similar chemical properties.
The elements having a similar outer electronic configuration in their atoms are arranged in the same group of the periodic table. These valence electrons are responsible chemical properties and reactivities of the elements.
Therefore, silicon and lead can be replaced by any element belonging to the same group in which Si and Pb are present. So we have germanium and tin. But germanium is the element that has an atomic mass greater than sulfur (S), but less than cadmium (Cd).
