Answer:

A covalent bond is the force of attraction that holds together two atoms that share a pair of electrons. It forms between atoms of the same or different nonmetals. In polar covalent bonds, one atom attracts the shared electrons more strongly and becomes slightly negative. The other atom becomes slightly positive

Explain why Ra is larger than Be. With 2 points.

igor_vitrenko [27]

Explanation:

<h2>Radium(Ra)=> </h2>

atomic number=88

<h2>BERYLLIUM (Be)=></h2>

atomic number =4

why is Ra larger than Be

<h3>1. since the atomic number of Ra is greater than Be, the number of electrons is more, which means there are more number of shells present in Ra than Be. </h3><h2>(atomic Radius)</h2>

<h2>2. the more the valence electron (excluding fully filled ones) the less is the nuclear attraction force</h2><h3>since Ra has more valence electron in its outermost shell, the nuclear attraction force is less which means that Ra 's size is greater than Be.</h3>

Consider the reaction: 2NO(g) O2(g) --> 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:

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