How I at least figure this problem out is I take a pencil and start on the right side of the 0 and make a loop to the left for each number and count until I get to the first two numbers that are between 1-9 when reading from left to right. This is where you put the decimal point. Some teachers rather you keep the 0's there, while others prefer one to get rid of them. Anyways with that new decimal number, you multiply the decimal by ten to what ever number you counted, which was 7.

The molecular mass of a compound is 92 g/mol. Analysis of the compound shows that it consists of 0.608 g of N and 1.388 g of O.
Pavel [41]

The empirical and molecular formula would be  NO_2 and  N_2O_4 respectively.

<h3>Empirical formula</h3>

The compound contains N and O.

N                                                        O

0.608/14 = 0.0434                        1.388/16 = 0.0867

Divide by the smallest.

N = 1                                             O = 2

Thus, the empirical formula would be NO_2

To get the molecular formula:

Empirical formula mass = 14 + (16x2) = 46

n = molar mass/empirical formula mass

          = 92/46 = 2

Thus, the molecular formula would be N_2O_4

Which statement explains how ATP and it's phosphate groups are relatedto energy that is used in plant processes
Zolol [24]

Hi my dear friend,

The statement that explain how ATP and its phosphate groups are related to energy used in plant process is that ADP gains a phosphate to create ATP, which stores energy for making sugars. These packets of energy in the form of ATP are then broken down to release energy and use that energy in synthesis of glucose.

~Thank you

Consider the reaction: 2NO(g) O2(g) --&gt; 2NO2(g) Suppose that at a particular moment during the reaction nitric oxide (NO) is
poizon [28]

Answer:

a. 0.0022 M/s

b. 0.0011 M/s

Explanation:

Let's consider the following reaction.

2 NO(g) + O₂(g) → 2 NO₂(g)

The rate of disappearance of NO is 0.0022 mol NO. L⁻¹.s⁻¹

<em>a. At what rate is NO₂ being formed?</em>

The molar ratio of NO to NO₂ is 2:2. The rate of formation of NO₂ is:

\frac{0.0022molNO}{L.s} .\frac{2molNO_{2}}{2molNO} =\frac{0.0022molNO_{2}}{L.s}

<em>b. At what rate is molecular oxygen reacting?</em>

The molar ratio of NO to O₂ is 2:1. The rate of disappearance of O₂ is:

\frac{0.0022molNO}{L.s} .\frac{1molO_{2}}{2molNO} =\frac{0.0011molO_{2}}{L.s}
