Answer:
2.47 M
Explanation:
Molarity is (mol of solute)/(L of solvent). To find molarity, convert grams of NaCl to moles of NaCl and milliliters of water to liters of water.
72.3 g ÷ 58.44 g/mol = 1.2372... mol
500 mL ÷ 1000 mL = 0.5 L
Molarity = 1.2372/0.5 = 2.47 M
In Silver, the 4d orbitals will be completely filled. That
implies that it does not have two electrons in the 5s orbital. The electronic
configuration of Silver is :
Ag (47) = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1
4d^10
Answer:
See below.
Explanation:
1 H (hydrogen) has a nucleus of just 1 proton.
2 H (deuterium) has a nucleus of 1 proton and 1 neutron
3 H (tritium) has a nucleus of 1 proton and 2 neutrons.
This is the answer to question 19. If it’s not clear, send me a message.
In a hydrocarbon's name,<span> the suffix -yl indicate that the molecule contains a functional group that is also a substituent and that there is another functional group that has a higher priority to it. The last part of the name of the functional group is replaced with -yl. For example, the alcohol functional group becomes hydroxyl.</span>
