Answer: Tens place.
Step-by-step explanation: hmm wait one moment
I am thinking the answer is B. I think this because Bohr had a model similar, but his was lacking the cloud of electrons. His just had electrons orbiting the nucleus.
I hope this is right!<span />
Answer:
B) 125 mL
Explanation:
M1V1=M2V2
(0.120M)(x)=(150.0 mL)(0.100M)
x= 125 mL

Answer:
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
Explanation:
Nuclei higher than Bi - 92 naturally are radioactive.
In a transmutation reaction, a new element is produced from an existing one due to radioactivity.
Nuclear fission is the radioactive process by which a heavy nucleus spontaneously decays into lighter ones with the release of a large amount of energy.
One example is the transmutation of uranium into thorium;
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
Answer:
The value is 
Explanation:
From the question we are told that
The mass of saxitoxin is 
The volume of water is 
The osmotic pressure is 
The temperature is 
Generally the osmotic pressure is mathematically represented as
Here R is the gas constant with value
and C is the concentration of saxitoxin
So
Generally the number of moles of saxitoxin is mathematically represented as
=> 
=> 
Generally the molar mass of saxitoxin is mathematically represented as
=> 
=>
