 carbon monoxide (CO)  <span> is made up of a coordinate covalent bond
</span>coordinate covalent bond is formed when both electrons forming the bonding pair of electrons are provided by the same atom

The correct option is E

Coordinate covalent bond is a type of covalent bond. A coordinate covalent bond is formed when a pair of shared electron comes from a single element. The pair of shared electron are held together by the force of the nucleus of the atom. This type of covalent bond is observed in carbon monoxide.

How many moles of N2O5 are needed<br> to produce 7.90 g of NO2?
Roman55 [17]

Answer:

0.085 moles of  N₂O₅ are needed

Explanation:

Given data:

Mass of NO₂ produces = 7.90 g

Moles of N₂O₅ needed = ?

Solution:

2N₂O₅       →     4NO₂  + O₂

Number of moles of NO₂ produced :

Number of moles = mass/ molar mass

Number of moles = 7.90 g/ 46 g/mol

Number of moles = 0.17 mol

now we will compare the moles of NO₂   with N₂O₅.

                NO₂          :       N₂O₅

                  4            :          2

                0.17          :         2/4×0.17 = 0.085 mol

Thus, 0.085 moles of  N₂O₅ are needed.

-BARSIC- [3]

Option A

The price elasticity of demand measures buyers’ responsiveness to a change in the price of a good.

<u>Explanation:</u>

Price elasticity of demand holds the responsiveness of need subsequent a variation in a product's cost. In different terms, it’s a process to comprehend out the responsiveness of buyers to inconstancies in cost. Price elasticity estimates the responsiveness of the measure necessitated or outfitted of a good to a shift in its demand.

The price elasticity of demand is the rate fluctuation in the amount demanded of a good or assistance distributed by the percentage shift in the price. Considering the quantity demanded habitually declines with value, the price elasticity coefficient is essentially forever negative.

What is happening at the atomic level to give rise to the observed energies in the flame tests and in the emission spectra
irina1246 [14]

Answer:

See explanation

Explanation:

According to the Bohr model of the atom, electrons are found in energy levels. Energy is absorbed or emitted when an electron moves from one energy level to another.

During flame test, electrons absorb energy and move to higher energy levels; they quickly return to ground state and emit the energy previously absorbed as a photon of light. This is seen as the colour imparted to the flame by the metal.

The emission spectrum tells us about the range of wavelengths emitted by an atom or compound when it is excited. At an atomic level, the electrons are moved to higher energy levels and as they return to ground state, they emit the various wavelengths that comprise the emission spectrum of any particular substance.
