Answer:Comparison of Ionic and Covalent Bonds
In an ionic bond, the atoms are bound together by the electrostatic forces in the attraction between ions of opposite charge. ... For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons.

Answer:
1. 2.510kJ
2. Q = 1.5 kJ
Explanation:
Hello there!
In this case, according to the given information for this calorimetry problem, we can proceed as follows:
1. Here, we consider the following equivalence statement for converting from calories to joules and from joules to kilojoules:
![1cal=4.184J\\\\1kJ=1000J](https://tex.z-dn.net/?f=1cal%3D4.184J%5C%5C%5C%5C1kJ%3D1000J)
Then, we perform the conversion as follows:
![600.0cal*\frac{4.184J}{1cal}*\frac{1kJ}{1000J}=2.510kJ](https://tex.z-dn.net/?f=600.0cal%2A%5Cfrac%7B4.184J%7D%7B1cal%7D%2A%5Cfrac%7B1kJ%7D%7B1000J%7D%3D2.510kJ)
2. Here, we use the general heat equation:
![Q=mC(T_2-T_1)](https://tex.z-dn.net/?f=Q%3DmC%28T_2-T_1%29)
And we plug in the given mass, specific heat and initial and final temperature to obtain:
![Q=236g*0.24\frac{J}{g\°C} (34.9\°C-8.5\°C)\\\\Q=1495.3J*\frac{1kJ}{1000J} \\\\Q=1.5kJ](https://tex.z-dn.net/?f=Q%3D236g%2A0.24%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2834.9%5C%C2%B0C-8.5%5C%C2%B0C%29%5C%5C%5C%5CQ%3D1495.3J%2A%5Cfrac%7B1kJ%7D%7B1000J%7D%20%5C%5C%5C%5CQ%3D1.5kJ)

Answer:
See explaination
Explanation:
The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.

The statement that best describes an advantage of cloning is that it can prevent genetic diseases. DNA cloning is a term used in recombinant DNA technology happens when a DNA strand belonging to one organism is transmitted into a particular type of genetic element having the capacity to self replicate. DNA cloning was developed to offer solutions related to healthcare and medical issues. Illnesses occur mostly because our body fails to produce essential proteins in ample amount is needed, these problems and other inherited problems may be solved using DNA cloning.
