Two boys, Adam and Bob are pushing a box. They want to move the box to the right. Adam exerts a force of 100 Newtons on the box and Bob exerts a force of 150 Newtons in the same direction.

A. Are the forces working in the same or opposite direction? ___________________
B. Do you add or subtract the forces? ____________________________________
C. What is the combined force (net force) on the box? ________________________
D. Are the forces balanced or unbalanced? ________________________________

Answer:

G) It would speed up evaporation.

Explanation:

As the temperature increases, the rate of evaporation also increases.

The product of the reaction is m-nitrobenzaldehyde, option B.

M-nitrobenzaldehyde, also known as meta-nitrobenzaldehyde is an organic aromatic compound that contains a nitro-group which is meta substituted to an aldehyde. It is soluble in water at 2.34 mg/ml and a temperature of 25° C. It is also soluble in ethanol, benzene and slightly in ether. M-nitrobenzaldehyde production process is prepared by nitration.

The carboxylic group is meta directing and has an ortho-para deactivating group therefore, during nitration of benzaldehyde, meta position gains an attachment from the nitro group forming m-nitrobenzaldehyde as product.

The full question is:

Predict the major product for the reaction shown.

a. o-cyanonitrobenzene & p-cyanonitrobenzene

b. m-nitrobenzaldehyde

c. o-cyanonitrobenzenesulphonic acid & p-cyanonitrobenzenesulphonic  acid

d. m-cyanonitrobenzenesulphonic acid

There are two molecular orbitals are needed to form one bonding molecular orbital and one anti-bonding molecular orbital.

Bond orbitals Electrons that spend most of their time between the nuclei of two atoms are placed in bonding orbitals, and electrons that spend most of their time outside the nuclei of two atoms are placed in anti-bonding orbitals.

Adding up the same number of atomic orbitals gives the same number of molecular orbitals. Two atomic orbitals combine to form two molecular orbitals. An anti-bonding orbital is essentially the opposite of a bonding orbital. They form when atomic orbitals combine in ways that lead to almost destructive interference.

Acids include hydrochloric acid (HCl) and bases include sodium hydroxide (NaOH). As a result, when they combine, they have a neutralization reaction that produces water and sodium chloride.

The pH rises to about 7 as a result of neutralization, which happens when a base and a base combine. It is a useful technique that is applied in daily life, for example when lime is added to acid soils to treat and relieve indigestion. Furthermore, neutralization results in an alkali's pH dropping to about seven.

Taking a base balances out our stomach's excess acid. Due to the formic acid in the ant sting, it can be painful. Using wet baking soda, which really is basic in nature, we can counteract this acid impact and lessen the agony brought on by the sting.

Answer: Yes, it is true, hydrogen bonding is strongest intermolecular forces compare with all. In case of nh3, (N-H bonds makes between molecules) and dipole dipole interaction (interaction between two dipole) and london dispersion forces occur between nh3 molecules. this types of intermolecular forces are generated between nh3 molecules.

Reactivity decreases as you move from left to right. The farther to the left and down the periodic chart you move, easier it is for electrons to be given or taken away, hence resulting in higher reactivity.

Reactivity decreases as we move down the column. As you learn more about the table, you will be able to find that this pattern is true for other families.

The atoms get bigger, as the atomic number increases. The chemical properties change slightly when compared to the element right above them on the table. The non-metal elements in Group 7 that are known as the halogens, get less reactive as you move to the down of the group.

The total time of decay is 8.18 min.

The half life is the time to takes a substance to decay. so, we half to find out the number of half lives that have passed for initial amount of 132.8 g.

         number of half -lives        amount of substances in g

                       0                                    132.8

                        1                                     66.4

                        4                                        8.3

so. it will take 4 half -lives for the substance to decay to 8.3 g.

the total time decay = 4 × 2.045 = 8.18 min.

Thus, A substance has a half-life of 2. 045 minutes. If the initial amount of the substance was 132. 8 grams, half - life will have passed before the substance decays to 8. 3 grams. the total time of decay is 8.18 min.

The wavelength is 241.77m.

What is frequency?

Hertz gives the frequency at which a recurring event occurs once every second (Hz). The number of vibrations or cycles per unit of time is the definition of frequency, as we are all aware.

What is wavelength?

A wave's wavelength is the separation between its successive crests, notably between the points of an electromagnetic wave.

frequency = 1.240*10^6 s^-1

speed of light = 2.998*10^-8 m/s

λ = wavelength

C= λv

λ=c/v

λ= 2.998*10^-8 m/s/1.240*10^6 s^-1

λ= 241.77m

Therefore, wavelength is 241.77m.
