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
When a cell with a 70% water concentration is placed in a solution with 30% water and 70% salt, water will move out of the cell into the surrounding solution due to osmosis. This occurs because water moves from an area of higher concentration (inside the cell) to an area of lower concentration (the external solution). As a result, the cell will lose water, potentially leading to cell shrinkage or crenation.
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.
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.

70% Hydrogen
Over 9000.
To find the average of 33 and 70, you add the two numbers together and then divide by 2. So, (33 + 70) / 2 = 103 / 2 = 51.5. Therefore, the average of 33 and 70 is 51.5.
When a cell with a 70% water concentration is placed in a solution with 30% water and 70% salt, water will move out of the cell into the surrounding solution due to osmosis.

As a result, the cell will lose water, potentially leading to cell shrinkage or crenation.
You are made of approx 70% water, all that water is 2/3 parts hydrogen, so no losing hydrogen is not better for you.
The legal alcohol concentration for most liquors is 70% to 80%. Most of the liquors are 80%.
