I’m pretty sure it would be B
Answer:
spheroidal joint
Explanation:
Ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.
Answer:
B. When it is obtained by rounding, as in 3.0
Explanation:
0.00162 is the Ksp of Ag2CO3 at 10 degrees.
Explanation:
Ag2CO3(s) --- 2Ag+
(aq) + CO3 ^-2(aq)
The product of molar solubility of each ion in moles/litre gives the solubility product.
The molar solubility of Ag2CO3 is 0.074 M at 10 degrees.
From the above reaction we can see that
2 Moles of Ag and 1 mole of carbonate ions,
So, [Ag2CO3]= 2[Ag]^2[CO3^2-]
Ksp of Ag+= 2*0.074
= 0.148
Ksp of CO3^-2= 0.074
= 0.148
Ksp of AgNO3= [0.148]^2 [0.074]
Ksp of AgNO3 = 0.00162 AT 10 degrees
The mass of a proton = 1.6726219 × 10^-27 kg.
It’s almost the exact same number as the mass of a neutron, which is 1.674927471×10^-27 kg. The mass of an electon is much less, even negligible.
I hope this helped you out!
