Explanation:

Remark

Interesting que8stion. You have to figure out how many mols are present in each reactant. Since all periodic tables are different, I'm going to use rounded numbers. If it is too close, I will go further.

NaCl

Na = 23

Cl = 35.5

1 mol = 58.5 grams

given = 50.0 grams

Mols for the reaction = 50/58.5 = 0.855

H2SO4

H2 = 2*1 2

S = 1 * 32 32

O4 = 4*16 64

1 mol = 98 grams

mols present = 50/98 = 0.510

MnO2

Mn = 1 * 55 = 55

O2 = 2*16 = 32

1 mol = 87 grams

mols available = 50/87 = 0.5747

Discussion

Na Cl and H2SO4 both require 2 moles for every mol of Cl2 produces.

H2SO4 has 0.51 mols available for a reaction

NaCl has 0.855 moles available for a reaction

MnO2 has 0.575 moles available for a reaction.

Given those numbers 0.510 mols of H2SO4 will only produce 0.255 mols of chlorine and the rest will be reduced in a similar manner. H2SO4 is the limiting reagent (reactant).

In other words only 0.510 moles of NaCl will be used and 0.855 - 0.510 moles will be left over on the reactants side.

only 0.575 moles of MnO2 will be used and 0.065 moles will be left over.

The oddity in the result shows up because the balance numbers in the equation give a ratio of 2 to 1 for H2SO4 and NaCl The 2 belongs to the reactants and the 1 for the chlorine.

Do you think flowers are important to mindkind? If yes explain why in your own words please it would mean a lot!!

Gemiola [76]

Answer:

Flowers play a crucial role in our lives; they have been used for generations to express the thoughts and feelings words cannot fully explain. Mother nature is the short term used to describe how nature gives life and nurture as a mother does for her children. As humans, we are part of mother nature's plan. We are also connected to plants and flowers, and some of the benefits have been passed to the next generation and will always be. We can control the air that we breathe, the aura around us, how we feel, and the things we attract in life. Other than only gifting your loved ones with flowers on special occasions, you can make the best and lasting impressions on your loved ones with a flower plant gift. This gesture shows that you understand how flowers are important in our life. To shed light on the importance of flowers in our life, here is a blog that will give five importance of flowers

At what temperature (in C) will a sample of gas occupy 91.3 L if it occupies 45.0 L at 70.0°C? Assume constant pressure.)

sdas [7]

Solution is here,

for initial case,

temperature(T1)=70°C=70+ 273=343K

vloume( V1) =45 L

for final case,

temperature( T2)=?

volume(V2)= 91.3 L

at constant pressure,

V1/V2 = T1/T2

or, 45/91.3 = 343/ T2

or, T2= (343×91.3)/45

or, T2=695.9 K = (695.9-273)°C=422.9°C

What value was a mole originally based upon?

Serggg [28]

I think the correct answer would be the number of atoms in a carbon isotope. This is because before mole was created atomic mass unit was first used to measure molecular stuff. Then, later on mole was created which is based on carbon-12 isotope.
