1. Hypnosis can help people stop smoking.(Yes)

To what extent does hypnosis work in regards to these behaviors?

A study by McNeilly and colleagues found that hypnosis may help quitters to focus on their own resources to curb cigarette cravings. Other researchers have suggested that success rates are caused by the relaxation effects of hypnosis. These might allow people to cope with nicotine addiction and nicotine withdrawal.

Would you recommend them? Why or why not?

I wouldn't recommend it because, The evidence for hypnosis as a successful smoking cessation method is a mixed bag. Some studies have seen high success rates, whilst others are more modest. A review of 59 different trials found that hypnosis is often better than no support at all.( so its a risk)

Answer:

2. A. solution

3. C The mass is different, but the melting behavior is the same

Melting points of enantiomers will not compare to each other as they have same M.P. and Diastereoisomers are compared on the basis of melting point.

Stereoisomers are those isomers which are having the same molecular formula but different spatial arrangemet of atoms within the molecule.

Hence, only diastereoisomers are compared on the basis of melting point.

Answer:

relative proportions of the elements in a chemical reaction

A molecule or a compound can easily be represented by their formula.Subscripts in chemical formulas are used to indicate the relative proportions of the elements in a compound.

A chemical formula represent the identity and number of elements in a molecule or compound. Each element in periodic table has their own symbols. For example, hydrogen is H, oxygen having O, N for nitrogen, Na for sodium etc.

These chemical symbols are came from the first one or two letters of the Latin names of the elements. The number of these elements in a compound is given as subscripts of their symbols.

For example, there are two hydrogens and one oxygen in  water and the formula is H₂O. Similarly the formula of carbon dioxide is CO₂ where one carbon and two oxygens are present. In this way the compounds can be easily identified and distuinguished using their chemical formulas.

Answer:

The answer is 36 atoms

Explanation: I took the test and i got 100%

There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

We have the expression "6 C₆H₁₂O₆", which represents 6 molecules of C₆H₁₂O₆.

The subscripts are the atomicities of the element, that is, the number of atoms of each element in 1 molecule.

There are 6 atoms of oxygen per molecule of C₆H₁₂O₆. Considering that there are 6 molecules, the total number of atoms of oxygen are:

[tex]6 Molecules \times \frac{6\ O\ atoms}{1Molecule} = 36\ O\ atoms[/tex]

There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".
