Answer: 693 g HNO3
Explanation: solution:
11.0 moles HNO3 x 63 g HNO3 / 1 mole HNO3
= 693 g HNO3
Use this formula which is th opposite of the formula used to find absorbance when you have the %T
(10^(-A))×100
where A=absorbance so
(10^(-0.85))×100
Answer:
Explanation:
Hello!
In this case, since it is observed that hot cadmium is placed in cold water, we can infer that the heat released due to the cooling of cadmium is gained by the water and therefore we can write:
Thus, we insert mass, specific heat and temperatures to obtain:
In such a way, since the specific heat of cadmium and water are respectively 0.232 and 4.184 J/(g °C), we can solve for the equilibrium temperature (the final one) as shown below:
Now, we plug in to obtain:
NOTE: since the density of water is 1g/cc, we infer that 25.00 cc equals 25.00 g.
Best regards!
The number of subshells in any given shell is equal to that shell's number. So the first shell (n=1) contains 1 subshell (1s). The second shell (n=2) contains 2 subshells (2s and 2p). The third shell (n=3) contains 3 subshells (3s, 3p, and 3d), and the fourth shell (n=4) contains 4 subshells (4s, 4p, 4d, and 4f).
<span>All d-type subshells have 5 orbitals, regardless of which shell they're in. s-type subshells contain 1 orbital each, p-type subshells contain 3 orbitals each, and f-type subshells contain 7 orbitals each. The answer would still be "five" even if you'd said 3d, 4d, or 6d...they all have five orbitals. </span>
