I believe the answer is: Protons and Neutrons
Protons weigh 1 amu while neutrons also weigh 1 amu. I’m not sure if they are talking about how many there is.

Hydrogen gas reacts with chlorine gas to form hydrogen chloride as shown in the following reaction: H2 (9) + Cl2 (g) + 2HCl (9)

vivado [14]

Answer:

467

Explanation:

ncl2 = 454.4x1/(71.0 g/mol) = 6.40 mols cl2

6.40 mols cl2 x 2molsHCL/1moleCL2 x 36.5g/1moleHCL = 467 g HCL

Adding more than one equivalent of HCl to pent-1-yne will lead to which product:______.

Ket [755]

Answer:

c. 2,2-dichloropentane.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to firstly draw the structure of the reactant, pent-1-yne:

$CH\equiv C-CH_2-CH_2-CH_2$

Now, we infer the halogen is added to the carbon atom with the most carbon atoms next to it, in this case, carbon #2, in order to write the following product:

$CH\equiv C-CH_2-CH_2-CH_2+2HCl\rightarrow CH_3- CCl_2-CH_2-CH_2-CH_2$

Whose name is 2,2-dichloropentane.

Regards!

Suppose a 5.00 l sample of o2 at a given temperature and pressure contains 1.08

arsen [322]

Missing question: A 5.00 L sample of O2 at a given temperature and pressure contains a 1.08x10^23 molecules. How many molecules would be contained in each of the following at the same temperature and pressure? 
a) 5.00 L H2.
b) 5.00 L CO2.
Use Avogadro's Law: The Volume Amount Law: equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. Because hydrogen and carbon(IV) oxide are gases, number of molecules are the same as number of oxygen molecules, so:
a) N(H₂) = 1.08·10²³.
b) N(CO₂) = 1.08·10²³

Which of the following contains the same number of electrons as an atom of neon?

asambeis [7]

Answer:

D. $O^{2-}$

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Oxygen has a total number of eight (8) electrons and as such the $O^{2-}$ is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon that has a total number of ten (10) electrons.

Hence, $O^{2-}$ contains the same number of electrons as an atom of neon.
