The correct IUPAC name of the following structure CH3-CH2-CH=CH2 is But - 1 - ene

<h3>IUPAC rules for alkene nomenclature</h3>
  • The parent alkene is chosen to have the longest carbon chain containing the carbon-carbon double bond.
  • The alkane's suffix "ane" is changed to "ene."
  • An alkene is referred to as a diene or triene depending on whether a double bond appears twice or three times in the parent chain.
  • the location of side chains or double bonds denoted by the numbers 1, 2, 3, etc.
  • The carbon atom in the double bond, which is written directly before the suffix "ene," receives the lowest number because it is the longest chain and is numbered from that end.
  • If both sides of a double bond receive the same number as the chain is being numbered, the carbon chain is numbered so that the substituent receives the lowest number.

Hence the structure CH3-CH2-CH=CH2 is named on the basis of the above rule as but - 1 - ene.

Approximately how many formula units of Co2(HPO4)3 are found in 175. g of hydrogenphosphate ion?
marshall27 [118]

Answer:

This question lacks options, the options are:

A. 2.89 x 1022

B. 8.66 x 1022

C. 3.66 x 1023

D. 1.10 x 1024

E. 3.29 x 1024

The answer is C. 3.66 × 10^23

Explanation:

In the chemical compound given as follows: Co2(HPO4)3, hydrogenphosphate ion is (HPO4)3.

Number of moles of hydrogenphosphate ion can be calculated using the formula

mole (n) = mass (m) /molar mass (MM)

Molar mass of (HPO4)3;

{1 + 31 + 16(4)}3

= {32 + 64)3

= (96)3

= 288g/mol

mole = 175/288

mole = 0.6076

mole = 0.607mol

The formula of units of hydrogenphosphate ion can be calculated by multiplying number of moles by Avogadro's number (6.022 × 10²³)

6.022 × 10²³ × 0.607

= 3.655 × 10²³

= 3.66 × 10²³

Unless otherwise instructed, you may use the periodic table in the Chemistry: Problems and Solutions book for this question.
Aleks [24]

Answer:

The electronegativity differences between carbon and oxygen are not very large.

Explanation:

Between the atoms of carbon monoxide exists a covalent bond which attaches the carbon to the oxygen.

In this type of bonding, both atoms shares a given number of valence electrons to attain chemical stability.

A substance is polar when there is a distinct charge separation between the species.

For covalent bonds, the electronegativity difference plays in important role in determining the polarity of the compound. When the difference is large, the compound will be polar but when the difference is very small or zero, no polarity will exist.

In between carbon and oxygen of carbon monoxide, the electronegativity difference is very low.

What are the missing coefficients for H3PO4 + HCl = PCl5 + H2o
grigory [225]

Answer:

H3PO4 + 5 HCl → PCl5 + 4 H2O

Explanation:

The given equation is

H3PO4 + HCl = PCl5 + H2O

The above chemical equation has one P atom on both the sides, hence phosphorus is balanced

There are 5 Cl on the RHS but only one Cl on the LHS. On balancing the chlorine, we get -

H3PO4 + 5HCl = PCl5 + H2O

Now, there are 8 hydrogen atom on the LHS but only two on the RHS. On balancing the hydrogen on both the sides, the new equation become

H3PO4 + 5HCl = PCl5 + 4H2O

Let us check for oxygen

Oxygen on LHS = 4 and oxygen on RHS = 4

Thus, the balanced equation is H3PO4 + 5HCl = PCl5 + 4H2O

What is the reaction if you mix vinegar Ajax bleach together.
Fantom [35]
The combination sounds like it'd be a powerful disinfectant, but the two should never be mixed. "Together, they produce chlorine gas, which even at low levels, can cause coughing, breathing problems, and burning, watery eyes," says Forte.
