The reaction of nitric oxide with hydrogen at 1280 c is 2no(g) +2h2(g)n2(g)+2h2o(g) from the following data collected at this temperature, determine the rate law and calculate the rate constant. initial rate (m/s) 1.3 x 10 5.0 x 10 experiment 1 2 3 no 0050 0100 0100 .0020 .0020 0040 10.0 x 105

Rate = 1.23*[NO]^2*[H2]

Explanation:

Data from question is unintelligible, so I'm going to use the table attached (the procedure doesn't change).

From experiments 1 and 2, when [H2] doubles, rate doubles; then, the order of reaction for [H2] is 1.

From experiments 2 and 3, when [NO] doubles, rate quadruples; then, the order of reaction for [NO] is 2.

The formula for the rate law is:

Rate = k*[NO]^2*[H2]

solving for the rate constant and replacing with the initial rate we get:

k = initial rate/([NO]^2*[H2])

k = 1.23*10^-3/(0.1^2*0.1) = 2.46*10^-3/(0.1^2*0.2) = 4.92*10^-3/(0.2^2*0.1)  = 1.23

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
