Nuclide, , also called nuclear species, species of atom as characterized by the number of protons, the number of neutrons, and the energy state of the nucleus. ... The term nuclide is not synonymous with isotope, which is any member of a set of nuclides having the same atomic number but differing mass number.

Answer:

The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.

Explanation:

The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.

Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.

Answer:

Air typically moves from areas of lower pressure to areas of higher pressure.

Answer:

There are now two oxygen atoms on the left and four on the right (in one N2O and three H2O's), so we balance the oxygen atoms by placing a 2 in front of the O2.

The numbers before atoms are the coefficients, and they are used to balance chemical reacions. In the provided example, number in front of O₂ is 3.

Note: Since I do not have the proposed reaction, I provided a random example.

A balanced chemical reaction is an equation in which the number and type of atoms are the same on both sides of the arrows.

Following the law of mass conservation, chemical equations should be balanced to ensure that all the reactants appear in the products.

This means that no new atoms appear, and no atoms disappear. The only thing that changes in a chemical reaction is the bond between atoms.

So each side of the equation must be equilibrated concerning the amount and type of atoms.

Coefficients are used to balance reactions. These numbers are located before each atom and indicate the number of units present in the formula.

I do not have the proposed reaction, but I will provide an example using O₂.

Reactants ⇒ 4 Al and 3 O₂

                     3 O₂ = 6 O

Products ⇒ 2 Al₂O₃

                    2 Al₂ = 4 Al

                    2 O₃ = 6 O

On each side of the equation we have 4 Al and 6 O. The only thing that changes are the bonds between atoms.

In this case, the coefficient of O₂ is 3.

Answer: Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Explanation:

Explanation:

Because a large amount of energy is required to break the strong inter-ionic attraction.

Explanation:

Fertilizers are chemically synthesized plant nutrients.

Nitrogen (N), Phosphorus (P) and Potassium (K) are macronutrients and are required in large amounts by plants. So, farmers use fertilizers in order to supply these nutrients. NPK 15:15:15 , NPK 20:20:20, NPK 15:30:15 are examples of fertilizers used to supply N, P, K to crops.

Explanation:

1.Potassium Nitrate(KNO3)

2.Potassium Sulphate(K2SO4)

They provide potassium to plants for making their roots and shoots healthy.

Answer:

In this earthquake-resistant building, two steel supports in the shape of an X (A) help to reinforce walls. Concrete walls with steel bars in them (B) lessen any rocking movements. Shock absorbers (C) take up some of the building’s kinetic energy during a quake. I could use the toothpicks as the two steel in the shape of an X. The concrete walls and the shock absorbers would be the marshmallows.

Features shown by points A, B & C are reinforce walls, concrete walls and shock absorbers respectively.

Earthquake is a kind of natural disaster in which an intense shaing of the earth's outermost layer takes place.

According to the image following points we will consider as:

We can use the toothpicks in the shape of X as the two steel and concrete walls & the shock absorbers as the marshmallows.

Hence, marshmallows are used as the concrete walls and toothpicks are used as two steel rods.

Answer:

4.5 × 1015 J

Explanation:

Energy was released through this form of mass.

The energy released if a sample loses 0.05 kg mass through

radioactive decay is  45 ×10¹⁴ J.

The ability to do work is called energy.

The Einstein's formula can be used to find the energy released. Energy is the product of mass  and  the velocity of light in a vacuum squared.

Given that the mass is 0.05 kg and speed of light in vacuum is 3×10⁸ m/s.

E = 0.05 × (3×10⁸)²

E = 45 ×10¹⁴ J

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

Answer:

Hydrogen (since this is all the info I'm working with)

Explanation:

Since we need to know how which substance has the most amount of molecules, we would need to look at the Atomic masses of these elements. Hydrogen has an atomic mass of 1.01g/mol whereas something like oxygen has an atomic mass of 16.00g/mol. Judging this, we can determine since a mole is made up of 6.02*10^23 molecules(Avogadro's number), and we have 1/1.01grams of hydrogen, we can deduce that Hydrogen would contain the largest amount of molecules

Answer:

Option A:

Dig into the zone of aeration

Explanation:

Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.

Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.

Answer:

1. 9.57 × 10^-9 moles.

2. 7.38mol

Explanation:

1.) To find the number of moles there are in the number of particles in an atom, we divide the number of particles (nA) by Avagadro's constant (6.02 × 10^23)

Hence, to find the number of moles (n) of Manganese (Mn), we say:

5.76 x 10^15 atoms ÷ 6.02 × 10^23

5.76/6.02 × 10^(15-23)

= 0.957 × 10^-8

= 9.57 × 10^-9 moles.

2.) Mole = mass/molar mass

Molar mass of sodium chloride (NaCl) = 23 + 35.5

= 58.5g/mol

mole = 431.6 g ÷ 58.5g/mol

mole = 7.38mol
