The balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

<h3>What are balanced chemical equations?</h3>

Balanced chemical equations are equations in wgich the moles of each species on both sides of the reaction are equal.

To balance chemical equations, numerical coefficients are placed in front of the species in the reaction.

The balanced equations of the reaction are as follows:

$3Pd + 4H_3PO_4 \rightarrow Pd_3(PO_4)_4 + 6H_2 \\$

$C_{11}H_{24} + 17O_2 \rightarrow 11CO_2 + 12H_2O \\$

$2Al(HCO_3)_3 + 3H_2SO_4\rightarrow Al_2(SO_4)_3 +6CO_2 +6H_2O \\$

Therefore, the balanced equation of the reaction shows that the mole of atoms on both sides of the reaction are equal.

Given 450.98 g of Cu(NO3)2, how many moles of Ag can be made? Provide your final answer rounded to two decimal places.

vivado [14]

Answer:

4.82 moles of Ag.

Explanation:

We'll begin by calculating the number of mole in 450.98 g of Cu(NO₃)₂. This can be obtained as follow:

Molar mass of Cu(NO₃)₂ = 63.5 + 2[14 + (16×3)]

= 63.5 + 2[14 + 48]

= 63.5 + 2[62]

= 63.5 + 124

= 187.5 g/mol

Mass of Cu(NO₃)₂ = 450.98 g

Mole of Cu(NO₃)₂ =?

Mole = mass /Molar mass

Mole of Cu(NO₃)₂ = 450.98 / 187.5

Mole of Cu(NO₃)₂ = 2.41 moles

Next, we shall determine the number of mole of Cu needed to produce 450.98 g (i.e 2.41 moles) of Cu(NO₃)₂. This can be obtained as follow:

Cu + 2AgNO₃ —> Cu(NO₃)₂ + 2Ag

From the balanced equation above,

1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂.

Therefore, 2.41 moles of Cu will also react to produce 2.41 moles of Cu(NO₃)₂.

Thus, 2.41 moles of Cu is needed for the reaction.

Finally, we shall determine the number of mole of Ag produced from the reaction. This can be obtained as follow:

From the balanced equation above,

1 mole of Cu reacted to produce 2 moles of Ag.

Therefore, 2.41 moles of Cu will react to produce = 2× 2.41 = 4.82 moles of Ag.

Thus, 4.82 moles of Ag were obtained from the reaction.

You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31 kilograms. How would you enter this number

mote1985 [20]

Answer:

The answer is the same as 9.11x10-31kg which is the mass of an electron,

Explanation:

The mass of an electron expressed in standard form is 9.11x10-31, which is the same thing as 0.000000000000000000000000000000911, while the former looks compact and easier to understand, the latter is clumsy,

The concept of three significant figures mean, three non-zero figures, in other words, provide your answer in an approximate form using three figures apart from zero, so you would try to express your answer in such a way that the first digit in your answer is not zero, in this case, its a "nine" - "9", and the other two significant figures are "1" and "1".

A compound with molecular formula C4H8O2, shows absorptions at 2500-3300 cm-1 (broad), 1720 cm-1 and at 1200 cm-1 on the IR spec

xxMikexx [17]

Answer:

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.

Explanation:

Solution:

First of all, we need to calculate the double bond equivalent (DBE) for the compound given:

Compound = C4H8O2

DBE = (C +1) - (H + X - N)/2

C = no. of carbons

H = no. of Hydrogen

X = no. of Halogens

N = no. of Nitrogen

DBE = (4+1) - (8/2)

DBE = 5-4

DBE = 1

It indicates the presence of 1 double bond in the possible structure.

Further structure can be identified by looking the peak values of the spectrum. So, we have,

2500 - 3300 = it indicates the presence of -COOH group

1720 = it indicates the (C=0) stretching

1200 = It indicates the (C-O) stretching

SO, the possible structure is

Butanoic Acid:

I have attached the structure of Butanoic Acid. Please refer to the attachment.
