Answer: B: Hydrogen bonds

Explanation: Hydrogen bond is a bond formed between a hydrogen atom and a electronegative atom such as fluorine, oxygen or nitrogen. It is a strong bond.

Ionic bond is formed by the transfer of electrons between metals and non metals.

London dispersion force is a temporary attractive force that results when the electrons in adjacent atoms occupy positions that make the atoms form temporary dipoles.

Dipole induced dipole interactions is a weak attraction that results when a polar molecule induces a dipole in a neighboring atom or a non polar molecule by disturbing the arrangement of electrons.

G x mol/g x atoms/mol= what are the units remaining after conversion

antiseptic1488 [7]

Answer:

The "unit" remaining after conversion is atoms.

This is a way to calculate the number of atoms, in an specific mass.

Explanation:

When you have a mass, multiplying the molar mass, "grams" are cancelled, so you finally obtained, number of moles.

Moles . atoms/mol, cancel the word mol so you will find out a number of atoms, present at the mass from, the begining.

For example, how many atoms are in 10 g of NaCl

Molar mass NaCl = Na mass + Cl mass

23 + 35.45 = 58.45 g/m

10 g . 1 / 58.45 mol/g . NA/ 1 mol = 3.42x10²⁰ atoms

NA = Avogadro number

Suppose that CO2 in the atmosphere was held at a constant, natural level for a few thousand years. Then, CO2 was added to double

jasenka [17]

Answer: Temperature before the increase in $CO_2$ was a few degrees lower than temperature after the increase.

Explanation:

According to Charle's Law which states that The volume of gas is directly proportional to the temperature of the gas, when pressure is kept constant.

$(Volume)\propto (Temperature)$
