By definition pH = - log10 [H+], where [H+] = concentration H+ of in mol/L
So at [H+] = 7.0*10-3 the answer will be pH = - log (7.0*10-3) = (2.1549) = 2.15
Around a resting neuron, there is a concentration gradient characterized by higher levels of potassium ions (K+) inside the cell and higher levels of sodium ions (Na+) outside the cell. This gradient is maintained by the sodium-potassium pump, which actively transports Na+ out of the cell and K+ into the cell. As a result, the resting membrane potential is typically around -70 mV, with the inside of the neuron being more negatively charged compared to the outside. This difference in ion concentration and charge is crucial for the generation of action potentials when the neuron is stimulated.
Hydrogen, specifically hydrogen nuclei undergoing nuclear fusion to form helium. This process releases energy in the form of heat and light, which powers the Sun and allows it to emit sunlight.

A concentration of 70% alcohol is generally preferred for sterilization during plant tissue culture. This is because a 70% solution is more effective at penetrating the cell walls of microorganisms, making it a better option for disinfection. Using absolute alcohol may be too harsh and could damage plant tissues.
its drinkable. there is 60% of it in your body. its h20. Which means 2 hydrogen atoms and 1 oxegen atom. it covers 70% of the earth.
70% of 103= 70% * 103= 0.7 * 103= 72.1
The Sun is about 70% hydrogen.
Perhaps Ytterbium, which has 103 neutrons and 70 electrons.

The legal alcohol concentration for most liquors is 70% to 80%. Most of the liquors are 80%.
You are made of approx 70% water, all that water is 2/3 parts hydrogen, so no losing hydrogen is not better for you.

Stars forming in the vicinity of the sun typically have hydrogen as their dominant element, making up about 70-75% of their mass. This high hydrogen content is essential for nuclear fusion processes in their cores, which powers their energy output.
