need the names for these asap please ​

In science, literature, and everything, equilibrium has the same meaning. The meaning simply put, is balance. If you wanted a sentence example, it could be something like:

'He sat down to try and recover his equilibrium.'

Or

'They can't maintain enough equilibrium to ride a bike.'

I hope you understand the meaning now?

Answer the first ine made up of 2 or more.....

All mixtures are made up of two or more elements or compounds.

Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.

Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:

1)Molecular compounds where in atoms are joined by covalent bonds.

2) ionic compounds where atoms are joined by ionic bond.

3)Inter-metallic compounds where atoms are held by metallic bonds

4) co-ordination complexes where atoms are held by co-ordinate bonds.

They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

C. Decomposition of potassium permanganate(Heating)

Explanation:

The equation of the reaction is given as;

2KMnO4 -> K2MnO4 + MnO2(s)  + O2(g)

Reactant = 2KMnO4

Products = K2MnO4 + MnO2(s)  + O2(g)

A. Oxygen turned in to carbon dioxide

Incorrect option - Oxygen is not the reactant

B. Sulphate and lithium boiled

Incorrect option -  Sulphate and lithium are not part of this reaction

C. Decomposition of potassium permanganate(Heating)

Correct option - potassium permanganate decomposed to form K2MnO4 + MnO2(s)  + O2(g)

D. None of the above

Incorrect option

➢number of moles. Moles and Chemical Reactions. Chapter 4. 3 H2. + N2. →. 2 NH3 ... How many grams of NH3 would form if 2.11 moles of N2 reacted with ...

Answer: because its more scientific and "formal"? I guess.

Explanation:

Answer:

Limiting reactant: O2

grams NO2 produced = 230.276 g NO2

grams of NO unused = 26.67 gNO

Explanation:

2NO + O2 --> 2NO2

Step 1: Determine the molar ratio NO:O2

molar ratio NO:O2 = 5.895: 2.503 = 2.35

stoichiometric molar ratio NO:O2 = 2:1

So, O2 is the limiting reactant.

Step2: Determine the grams of NO2:

?g NO2 = moles O2 x (2moles NO2/1 mol O2) x (MM NO2/ 1 mol NO2) = 2.503 x 2 x 46 = 230.276 g NO2

Step 3: Determine the amount of excess reagent unreacted

moles excess NO reacted = moles O2 x (2 moles NO/1 mol O2) = 2.503 x 2 = 5.006 moles NO reacted

moles NO unreacted = total moles NO - moles NO reacted = 5.895-5.006 =0.889 moles NO unreacted

mass NO unreacted = moles NO unreacted x MM NO = 0.889 x 30 =26.67 g NO unreacted

Answer:

C

Explanation:

No change.

The total number moles of products = The Total number of reactants

Explanation:

According to the concept of percent yield, the percent yield of carbon dioxide is 72.51%.

Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.

In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .

In the given example, theoretical yield of carbon dioxide is as 32 g oxygen produces 44 g carbon dioxide,thus 32.5 g which is obtained by 2.5 moles of oxygen will require 32.5×44/32=44.68 g

Thus , on substitution in formula of percent yield, 32.4/44.68×100=72.51%.

Hence, the percent yield of carbon dioxide is 72.51%.

The concept of significant figures are mainly used by scientist and engineer to know the significance of digits in a measurement. Therefore, 3,545,530 upto 3 significant figures is 3.54 x 10³.

Significant figures are the figures that indicate the degree of accuracy of a value. It tells about the precision of a value. It gives an idea about the digits that are necessary to indicate the experimental value.

Rules for counting significant figures are:

Number between 1 to 9 is always significant

Zeroes after a number has got no significance

Zeroes before a number has got no significance

Zeroes between number has got significance

3,545,530 upto 3 significant figures is 3.54 x 10³.

Therefore, 3,545,530 upto 3 significant figures is 3.54 x 10³.

Answer:

60 Liters

Explanation:

The equation for this reaction is given as;

N2 + 3H2 → 2NH3  

From the reaction;

3 mol of H2 produces 2 mol of NH3

At STP;

1 mol = 22.4 L

This means

67.2 L ( 3 * 22.4) of H2 produces 44.8 L ( 2 * 22.4) of NH3

How many L of H2 would produce 40 L of NH3

67.2 = 44.8

x = 40

Solving for x;

x = 40 * 67.2 / 44.8

x = 60 L
