Answer:There are three main properties of chemical bonds that must be considered—namely, their strength, length, and polarity. The polarity of a bond is the distribution of electrical charge over the atoms joined by the bond. Specifically, it is found that, while bonds between identical atoms (as in H2) are electrically uniform in the sense that both hydrogen atoms are electrically neutral, bonds between atoms of different elements are electrically inequivalent. In hydrogen chloride, for example, the hydrogen atom is slightly positively charged whereas the chlorine atom is slightly negatively charged. The slight electrical charges on dissimilar atoms are called partial charges, and the presence of partial charges signifies the occurrence of a polar bond.
Explanation:
The correct answer is (a) wave the fumes toward your nose with your hand. If you smell the chemicals directly, it could be harmful too your health, especially if they are strong. Also remember to <em>never </em>smell chemicals unless you are being told to do so.
Your answer would come out to 18 electrons
Answer:
The mass of titanium displaces 68.6 mL of water is 309.4 g.
Explanation:
Given that:-
Also, 1
= 1 mL
So,
The expression for the calculation of density is shown below as:-
Using the above expression to calculate the mass as:-
Applying the values to calculate the mass as:-
<u>The mass of titanium displaces 68.6 mL of water is 309.4 g.</u>
Answer:
The new volume is 5.92 L, which is approximately 6 L
Explanation:
As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.
So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
- If the temperature increases the volume increases
- If the temperature decreases the volume decreases
Mathematically this is expressed by:

When you want to study two different states, an initial and a final one of a gas, this law is expressed by:

In this case:
- V1: 8 L
- T1: 473 K
- V2: ?
- T2: 350 K
Replacing:

Solving:

V2=5.92 L
<u><em>The new volume is 5.92 L, which is approximately 6 L</em></u>
