Which equation represents a spontaneous transmutation
Answers
37/20Ca --> 37/19K + 0/+1e
Explanation:
Transmutation, conversion of 1 element into another. A transmutation entails an amendment within the structure of atomic nuclei and thus is also induced by an action (q.v.), like nucleon capture, or occur ad libitum by decay, like disintegration and disintegration(qq.v.)

moles of H+ = 0.5 M * 0.025 L HCl = 0.0125 moles H+
moles of OH- should be equal to 0.0125 moles, so
0.0125 moles = (x) * 0.025 L NaOH
x is the concentration of NaOH, which we want to find.
x = 0.5 M
The correct answer is C) 0.5 M.

here are the steps 2 get the same ans:
(NH4)2 CO3 has 2x N, 8x H, 1x C and 3x O per molecule
so its molecular mass = 2x14 + 8x1 + 1x12 + 3x16
=28+8+12+48
=96g
of that 96g, 8x1=8g is due to Hydrogen
so by ratio n proportion, 1.00g will have 1x8/96 = 1/12g = 0.083g of H

Answer:1 Liter (L) is equal to 1000 milliliters (mL). To convert liters to mL, multiply the liter value by 1000. For example, to convert 2 liters to mL, multiply 2 by 1000, that makes 2000 mL is 2 L.

Because there are 73 Protons and that equals the Atomic Number .. what is the element that is 73 as its atomic number?
Tantalum
Because we know that there are 73 Protons and 108 Neutrons ..we could do this 73+108 = 181
So its name is Tantalum-181
hope this helps.
Final answer:
The mass number of an atom with 92 protons and 108 neutrons is 200.
Explanation:
To calculate the mass number of an atom that has 92 protons and 108 neutrons, you simply add these two numbers together. The mass number of an atom is comprised of the total number of protons and neutrons in its nucleus. So, 92 protons + 108 neutrons = 200. Therefore, the mass number of the atom is 200.
