The sequence of individual steps, or elementary reactions, by which reactants are converted into products during the course of a reaction is called the reaction mechanism. The overall rate of a reaction is determined by the rate of the slowest step, called the rate-determining step.

what happens to the electronegatity when you go from top to bottom on the periodic table?

Answers

Answer:

It decreases

Explanation:

As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.

Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.

Janet is sliding a box across the floor what does she need to know to calculate the force on a box?

Answers

Answer:

She needs to know the Mass and acceleration

Janet needs to know the mass of the box and acceleration .

What is force?

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object  which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton  and is represented by'F'.Newton's second law states that force which acts on an object  is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

1) Sour taste - Put some soda on your tongue

2) Corrode metals - Put a little soda on a clean metal surface

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Does Soda show acidic properties?

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

10. A gas sample that has a mass of 6g occupies 400 mL at 504°C and a pressure of 600 mm Hg. Calculate the gas’s density at STP.

Answers

Answer:

51 g/mol

Explanation:

Whenever you see molar masses in gas law questions, more often than not density will be involved. This question is no different. To solve this, however, we will first need to play with the combined ideal gas equation PV=nRT to make it work for density and molar mass. The derivation is simple but for the sake of time and space, I will skip it. Hence, just take my word for it that you will end up with the equation:

Use the equation below to solve the problem that follows.

2H2 (g) + O2 (g) → 2H2O (g)

Explanation:

The number of moles = given mass / molar mass

The given mass is 66 g and the molar mass is 44 g/molar mass

Substituting the values in, we get that:

the number of moles = 66/44

the number of moles = 1.55

cyclohexane and CH2Cl2


CH3CH2OCH2CH3 and CH3CN

Answers

Answer:

See explanation

Explanation:

1. The Ketone was not sown in the question but i can give you a general idea of how to calculate its molecular weight. A ketone has a general molecular formula of CnH₂nO.

The molecular weight is calculated knowing that the relative atomic mass of carbon is 12, that of hydrogen is 1 while that of oxygen is 16.

Hence from the general molecular formula, the molecular weight of any ketone is calculated from; n(12) + 2n(1) + 16. Where n represents the number of atoms of each element in the ketone.

2. Sublimation of dry ice occurs when the molecules in dry ice absorb sufficient energy in the form of heat such that they now have enough energy for some molecules to overcome the inter molecular forces acting in the solid crystal and transform directly into the vapor phase. This process is endothermic.

3.  

cyclohexane and CH2Cl2 molecules are held together by dispersion forces.

CH3CH2OCH2CH3 and  CH3CN are polar molecules held together by  dipole-dipole forces.

True, Plants don't have brains, but they still adapt to their environments.

What is adaptation?

Adaptation is a process where they are changing their nature to suit the environment.

We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.

Hence, plants have no brains, but they still adapt.
