Calculate the quantity (in mmol) of protons that will be released when 2.80 mmol of oxygen bind to deoxyhemoglobin at ph 7.4 and the ph then returns to 7.4, i. e. in going from point a to point b on the curve. step 1: calculate the [hhb]/[hb] ratio at ph 7.4. step 2: calculate the mmol of hhb in 2.80 mmol of deoxyhemoglobin at ph 7.4. step 3: calculate the [hhbo2]/[hbo2] ratio at ph 7.4. step 4: calculate the mmol of hhbo2 in 2.80 mmol of oxyhemoglobin at ph 7.4. step 5: calculate the protons released as the difference between nhhb and nhhbo2.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

idk i'm not smart

explanation:

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
