<u><em>Answer:</em></u>

<u><em>49.98</em></u>

<u><em>Explanation:49.98 should be the correct answer but if you start with 49.98 g H2O2 and decompose all of it you do not get 34.00 g H2O and 15.98 g O2. </em></u>

What is the mole ratio of NH3 to N2?
Ksenya-84 [330]
To answer this question a balanced chemical equation is necessary. The correct equation is: N2 + 3H2 = 2NH3
From this equation, one mole of nitrogen react with 3 moles of hydrogen to give 2 moles of ammonia.
Therefore, the mole ratio of NH3 to N2 is 2:1

This is my chemistry worksheet. It's a new topic my teacher will barely review with us. Help please???
TEA [102]
So to balance an equation, you need to get the same amount of each type of element on either side of the --> . So you pretty much are given the subscripts in the equations and you need to add coefficients (just normal numbers) in front of any formula that needs it, keeping anything balance.
KCl_{3}  + O_{2}  -\ \textgreater \  KCl_{3}
turns into
2KCl_{3}+ 3O_{2} -> 2KCl_{3}

These coefficient numbers are the molar ratios, so 2 moles of KCl3 for every 3 moles of O2   so 1. 3:2

Then you can use these ratios of find out how many moles of one thing are needed if you are given the amount of another.
\frac{moles of element 1}{cofficient 1}  =  \frac{moles of element 2}{cofficient 2}
and use cross multiplication to solve for whatever you don't know

The synthesis of 5-phosphoribosylamine from PRPP is
mel-nik [20]

Answer:

The correct answer is option B: "I, II".

Explanation:

The synthesis of 5-phosphoribosylamine from phosphoribosyl pyrophosphate (PRPP) is inhibited allosterically by ATP and GTP and activated by PRPP via feed forward activation. The enzyme that regulate this process is the enzyme amidophosphoribosyltransferase (AMPRT), which is stimulated by increased PRPP concentrations and is inhibited allosterically by ATP and GTP as well as IMP, AMP, and GMP.

a solution was made by mixing sodium chloride () and water (). given that the mole fraction of water is 0.980 in the solution ob
Mnenie [13.5K]

The mass of sodium chloride used <u>was 1.17 grams</u><u>.</u>

The mole fraction can be calculated by way of dividing the number of moles of 1 factor of an answer via the full variety of moles of all the additives of an answer. it is mentioned that the sum of the mole fraction of all the components inside the solution has to be the same as one.

mass  of NaCl given =  64.9 g

mole  = mass/molar mass

          = 64.9 / 58.5

          =<u> 1.109</u>

a mole fraction of water =  0.980

mole fraction of NaCl = 1 - 0.980

                                   = <u>0.02</u>

1 mole of NaCl =  58.5

mass of NaCl  = 58.5 × 0.02

                       =<u> 1.17 gram</u>

Mole Fraction describes the range of molecules contained within one aspect divided through the whole range of molecules in a given combination. it's miles quite beneficial whilst two reactive-natured components are mixed collectively.
