9 g of hydrogen - 42 g of nitrogen
5 g of hydrogen - x g of nitrogen

The mass of nitrogen in the second sample is 23.33 g.
Answer:
9.25
Explanation:
Let first find the moles of
and 
number of moles of
= 0.40 mol/L × 200 × 10⁻³L
= 0.08 mole
number of moles of
= 0.80 mol/L × 50 × 10⁻³L
= 0.04 mole
The equation for the reaction is expressed as:

The ICE Table is shown below as follows:

Initial (M) 0.08 0.04 0
Change (M) - 0.04 -0.04 + 0.04
Equilibrium (M) 0.04 0 0.04







for buffer solutions
since they are in the same solution


Answer:
42.38875878%
Explanation:
i divided 4.27 g from 1.81g using a percentage calculator but im not sure if its correct
It affects the volume of air you can inhale.
The answer for above statement is:
p4(s)+10hclo(aq)+6h2o(l)→4h3po4(aq)+10hcl(aq) br2(l)+2k(s)→2kbr(s) ch3ch2oh(l)+3o2(g.
Explanation:
An reaction (redox) reaction may be a style of chemical process that involves a transfer of electrons between 2 species. An redox reaction any chemical process during which the oxidation state of a molecule, atom, or particle changes by gaining or losing an electron.
