Answer:

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 & Explanation:

For the water to H2 and O2 problem:

1) Reactant is H20, it is to the left of the arrow.

2) Products are H2 (gas) and O2 (gas) because it is to the right and what is created.

For the CO2 + water -> Glucose + Oxygen problem:

1) Reactant is CO2 and H2O, it is to the left of the arrow and what is being changed.

2) Products are C6H12O6 (glucose) and O2 (gas) because it is to the right and what is created.

you will divide 36 by 1 and multiply 2 on both sides which makes 72 by 2 so 2into 1 is 2 and 2 into 36 is 72

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 500 g

volume = 67 mL

We have

[tex]density = \frac{500}{67} \\ = 7.462686[/tex]

Adding ice to the liquid decreases the average kinetic energy of the particles of the liquid.

The temperature of a substance is defined as a measure of the average kinetic energy of the molecules of the substance. The average kinetic energy of the molecules of a substance is directly proportional to the temperature of the substance.

This implies that if I increase the temperature of a substance, the average kinetic energy of the molecules of the substance increases and vice versa.

Ice is at a lower temperature than water at room temperature. Thus, adding ice to water at room temperature decreases the temperature of the water and consequently decreases the average kinetic energy of its particles.

hehe I needed some brianliest plz OK

Explanation:

Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.

Glucose and mannose are epimers that differ at the C-2 carbon, while glucose and galactose are epimers that differ at the C-4 carbon, as shown below. When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1.

Answer:

Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
