Hey there!:
Molarity of NaOH = 6 M or 6 mol/L
Volume of NaOH = 40 mL
Therefore , number of moles of NaOH:
40 mL =( 6 mol / 1000 mL)*40=
6/ 1000 * 40 => 0.24 moles of NaOH
Hope this helps!
Answer:
After the concentration of H₂ is decreased
H₂+↑Br₂⇒↓2HBr
After the concentration of HBr is increased
↑H₂+↑Br₂⇒2HBr
Explanation:
After the concentration of H₂ is decreased, there will not be enough H₂ to from HBr, so the concentration of HBr will decrease, and the concentration of Br will increase.
After the concentration of HBr is increased, there would be more HBr that will give more H₂ and Br₂.
Answer:
- <u>1. Since the temperature of your body is higher than the temperature of the air and of the water, heat will flow from your body to the air and pool.</u>
<u></u>
- <u>2. The pool feels cooler than air because the water can absorb heat energy faster than the air, due to liquids are better conductors than gases.</u>
<u></u>
Explanation:
Heat always flows from warmer substances to colder ones.
The normal body temperature is 98ºF. Therefore, the heat will flow from your body to the air and pool, which are at a lower temperature of 80ºF. In both cases, you will lose thermal energy and the external parts of your body will cool down.
The difference between both cases is in the heat conduction capacity of both air and water.
Liquids (and solids) are better <em>thermal conductors </em>than gases because the conduction of heat occurs as result of the direct contact between the particles of matter: the atoms or molecules in hot matter vibrate faster than their neighbors and transmit them kinetic energy by direct contact.
Therefore, the liquid water in the swimming pool, at the same temperature than the air, will be able to absorb more heat in the same time from the body.
In conclusion, the body will cool down faster in water than in air which is why the pool feels cooler than air.
The answer is option 1. The first ionization energy is the energy required to remove the most loosely held or the outermost electrons from one mole of the atom to 1 mole of ion with a charge of 1+.
