Rocks that are found on the moon are similar to those found near volcanoes most likely because the suffocated atmosphere is the same.

What is the hydrogen ion concentration ([H']) of a substance with a pH of 4.91?

Ksenya-84 [330]

Answer:

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

What is the number of moles of glucose (C₆H₁₂O₆) in 0.500 L of a 0.40 M solution?

WITCHER [35]

Answer:

0.20 moles

Explanation:

In order to solve this problem it is necessary to keep in mind the definition of molarity:

Molarity = moles / liters

If we input the data given by the problem we're left with:

0.40 M = moles / 0.500 L

Meaning that we can proceed to calculate the number of moles:

moles = 0.40 M * 0.500 L

moles = 0.20 moles

Please help it is very easy and hard for me to figure out where the words go will give brainliest !!! And this isn't even chemis

GrogVix [38]

Answer:

In the explanation

Explanation:

First of all, make sure you re-read the lesson carefully and memorize the definitions. pls

forces are push and pull.

And just give an example of like someone pushing a sofa into the living room (push).

Another example of pull is pulling a door knob to open a door.

And ANOTHER example can be pushing a tissue box or anything.

Forces can be balanced and unbalanced, that is correct.

When the netforce is equal to 0 then it is balanced, if not then it’s unbalanced.

Balanced which results a netforce equals to 0, there is no change in motion.

Unbalanced which causes in the object's motion changing (For example an tug of war, some guy pulls 10N to the right and the other person 5N to the left, obviously the netforce will be 5N to the right; Unbalanced force)

Last two boxes, maybe add examples as I mentioned? And add another example from ur textbook or something.

[Co(H2O)6]2+(aq) + 4Cl-(aq) ⇌ [CoCl4]2-(aq) + 6H2O(l)

pav-90 [236]

Answer:

For A: The expression for $K_{eq}$ is given below.

For B: The value of $K_{eq}$ at 25°C is 0.0185512

For C: The value of $K_{eq}$ at 65°C is 0.2887886

For D: The reaction is endothermic in nature.

Explanation:

For A:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$

For the given chemical reaction:

$[Co(H_2O)_6]^{2+}(aq.)+4Cl^-(aq.)\rightleftharpoons [CoCl_4]^{2-}(aq.)+6H_2O(l)$
