Answer:

The name of the two parts found on the left side of the equation is <u><em>reactants.</em></u>

Explanation:

Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.

Reactants ⇒ Products

Then, <u><em>the name of the two parts found on the left side of the equation is reactants.</em></u>

Does carbon ever leave the EARTH? Explain.
GrogVix [38]

Answer:

Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.

How many moles is<br> 55 g of Naci?<br> 0.025 g of NaCO3?
mart [117]

Answer:

0.940mol &

0.000301mol respectively.

Explanation:

number of moles = given mass / molar mass

given mass of Nacl = 55g Molar mass = 23 + 35.5

n=m/M = 55g/58.5g/mol = 0.940mol

note- (add the atomic weights of sodium and chlorine to get the molar mass of Nacl.) = 58.5g/mol

similarly, NaCO3 = 23 + 12 + 16*3 = 83g/mol

n=m/M = 0.025g/83g/mol = 3.01 * 10^-4 = 0.000301mol

extra: If you ever get asked to put it in number of particles just use the relation of 1mole = 6.02 * 10^23 particles.

What is the molarity of a solution prepared by dissolving 10.0 grams of NaOH in enough water to make a solution with a total vol
riadik2000 [5.3K]

Solution :

Molecular mass of NaOH is 23 g/mol .

So, number of moles of NaOH is given by :

n = \dfrac{10}{40}\ mole

Now, we know molarity is given by :

Molarity = \dfrac{Number \ of \  moles\ of \ salute}{Volume ( in \  Liter ) }

M = \dfrac{10}{40\times 2.4} \  M\\\\M = 0.104 \ M

Hence, this is the required solution.

You titration 5.0 mL of HCl with 0.010 M NaOH. You find the end point of your titration occurs when 12.0 mL of NaOH has been add
Nookie1986 [14]

your answer is 0.00833M the volume was converted into liters

NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)

Using the molarity equation, we can find the number of moles of HCl that reacted:

molarity=mol soluteL soln

mol solute=(molarity)(L soln)

mol HCl=(0.105molL)(0.0250L)=0.00263 mol HCl

(volume converted to liters)

Now, using the coefficients of the chemical reaction, we can determine the number of moles of NaOH that reacted:

0.00263mol HCl(1lmol NaOH1mol HCl)=0.00263 mol NaOH

Lastly, we'll use the molarity equation (using given volume of NaOH soln) again to determine the molarity of the sodium hydroxide solution:

molarity=mol soluteL soln
