The correct answer is option C. Solutions that have more OH– than H+ ions are bases. These are substances that are slippery to touch and has an astringent taste. It reacts with acids in a neutralization reaction forming salts. It accepts protons. Examples are sodium hydroxide and potassium hydroxide.
Answer:
Explanation:
as we know density is g/ml or d=(g/ml) we will plug in the values in their respective positions and get the answer.
So the density is 0.812(round it according to the sig figs it asks for).
C because ships and other boats has underwater microphones underwater because on most cargo ships the engine is to loud so they use microphones underwater to detect torpedos so your answer is C
Can you show a picture instead so I can see
Answer:
Its pressure will be 0.54 atm at 100 K.
Explanation:
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
Gay-Lussac's law can be expressed mathematically as the quotient between pressure and temperature equal to a constant:
![\frac{P}{T} =k](https://tex.z-dn.net/?f=%5Cfrac%7BP%7D%7BT%7D%20%3Dk)
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
![\frac{P1}{T1} =\frac{P2}{T2}](https://tex.z-dn.net/?f=%5Cfrac%7BP1%7D%7BT1%7D%20%3D%5Cfrac%7BP2%7D%7BT2%7D)
In this case:
- P1= 1.75 atm
- T1= 50 °C= 323 K (being 0 C=273 K)
- P2= ?
- T2= 100 K
Replacing:
![\frac{1.75 atm}{323 K} =\frac{P2}{100 K}](https://tex.z-dn.net/?f=%5Cfrac%7B1.75%20atm%7D%7B323%20K%7D%20%3D%5Cfrac%7BP2%7D%7B100%20K%7D)
Solving:
![P2= 100 k*\frac{1.75 atm}{323 K}](https://tex.z-dn.net/?f=P2%3D%20100%20k%2A%5Cfrac%7B1.75%20atm%7D%7B323%20K%7D)
P2= 0.54 atm
<u><em>Its pressure will be 0.54 atm at 100 K.</em></u>
