<span>When a sound wave reaches near the ear, the outer part of the ear acts like if its a funnel, so it catches the wave and funnels it into the ear. They the wave hits the eardrum. Then the bones in the eardrum cause each other to vibrate. Then they are sensed by nerves and sends signals to the brain to interpret sound. Hope This Helps!</span>

Part d based on your answer to part c, how many bonding electrons and lone pair electrons (nonbonding electrons) are there in th

elena55 [62]

The Lewis Structure of HCN is shown below,

Number of Bonding Electrons:
In HCN Hydrogen is bonded to Carbon through single bond and Nitrogen is bonded to Carbon through Triple Bond. Single bond is formed by two bonding electrons, while, triple bond is formed by six bonding electrons, Hence,

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons:
In HCN there is only one lone pair of electron present on Nitrogen atom which is not taking part in bonding. Hence,
Number of Non-Bonding Electrons = 2

Result:

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons = 2

If you have 5 moles of carbon dioxide at 30degrees C and under 600mmHg of pressure, what will the volume be

trapecia [35]

Answer:

157.64 L

Explanation:

We'll begin by converting 30 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

T(°C) = 30 °C

T(K) = 30 °C + 273

T (K) = 303 K

Next, we shall convert 600 mmHg to atm. This can be obtained as follow:

760 mmHg = 1 atm

Therefore,

600 mmHg = 600 mmHg × 1 atm / 760 mmHg

600 mmHg = 0.789 atm

Finally, we shall determine the volume of the gas. This can be obtained as follow:

Number of mole (n) = 5 moles

Temperature (T) = 303 K

Pressure (P) = 0.789 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) =?

PV = nRT

0.789 × V = 5 × 0.0821 × 303

0.789 × V = 124.3815

Divide both side by 0.789

V = 124.3815 / 0.789

V = 157.64 L

Therefore, the volume of the gas is 157.64 L
