Hey there!:

Molar mass CO2 = 44.01 g/mol

44.01 g CO2 ------------------- 6.02*10²² molecules CO2

88 g CO2 ------------------------ y

y = 88 * ( 6.02*10²² ) / 44.01

y = 5.29*10²⁵ / 44.01

y = 1.2 * 10²⁴ molecules of CO2

Answer A


Hope that helps!

Hi, can someone help me balance this chemistry equation:<br> H2SO4 + RbOH -&gt; Rb2SO4 + H2O
zloy xaker [14]

H2SO4 + 2RbOH -> Rb2SO4 + 2H2O

If you want an explanation, keep reading.

In the first portion, there are two hydrogen ions and four sulfate ions.

The second portion has one rubidium ions and one hydroxide ion.

On the other side of the equation, in order to keep those two rubidiums balanced, you'll need to add a two at the beginning of the second portion, but in that process you are giving a second hydroxide value.

Back to the right side, there is there is water (H2O).

On the first portion, there were two hydrogen ions. The second portion also has two hydroxides because of the value change (adding the two to the front).

So on the fourth portion, you'd have to add another two so you could balance the four hydrogen ions (H2 and 2OH) and the two oxygen ions (2OH).

I hope this was easy to understand.

Categorize each hydrocarbon as being saturated or unsaturated.
Bond [772]

Answer :

Saturated hydrocarbon : 3-methyloctane, propane, heptane.

Unsaturated hydrocarbon : cyclopentene, heptyne

Explanation :

Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.

For example : Methane, Ethane, etc.

Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds.

For example : Ethene, Butyne, etc.

Therefore, the saturated and unsaturated hydrocarbons are:

Saturated hydrocarbon : 3-methyloctane, propane, heptane.

Unsaturated hydrocarbon : cyclopentene, heptyne

Describe two types of mechanical weathering
Nuetrik [128]
The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD

The enthalpy of vaporization for water is 40.67 kJ/mol and the enthalpy of fusion for water is
S_A_V [24]

Answer:

\Delta H_{dep}=-46.68kJ/mol

Explanation:

Hello!

In this case, since vaporization is the processes by which a liquid goes to the gas phase, fusion by which a solid goes to liquid and deposition by which a gas goes to solid; we infer that the following set up relates the enthalpies associated to each process:

\Delta H_{fus}+\Delta H_{vap}=-\Delta H_{dep}

Because deposition goes from a state with more energy to a state with less energy, therefore it is negative; in such a way, by plugging in we obtain:

\Delta H_{dep}=-(\Delta H_{fus}+\Delta H_{vap})\\\\\Delta H_{dep}=-(6.01kJ/mol+40.67kJ/mol)\\\\\Delta H_{dep}=-46.68kJ/mol

Best regards!
