Answer:

D. decomposing

General Formulas and Concepts:

Chemistry

Explanation:

A would be incorrect because mixing 2 things together doesn't necessarily create a chemical change. Take oil and water for example. You can mix the 2 and it would not have a chemical change.

B would be incorrect because you are simplify changing the state of matter of the object. Iron in solid form is still iron in liquid form; there is no chemical change.

C would be incorrect for similar reasons as B. You are simply changing the state of matter.

D would be the remaining and correct answer. Decomposing changes one object into a different one by chemically changing.

Answer:

Whether the forces of attraction is strong or weak is explained below in details.

Explanation:

There are three distinct kinds of intermolecular forces in expressions of energy. They are (strongest to weakest) dipole-dipole, hydrogen bonding, and Van der Waals' strengths. Intermolecular forces are weak related to intramolecular forces – the energies which endure a molecule collectively. For instance, the covalent bond, including distributing electron sets among atoms, is much more powerful than the forces impersonate among neighboring molecules.

Answer:

chemical change

Explanation:

particals react to temperature wheteher its cold or warm

The  particles begin to move at a higher speed. It is a physical change.

Temperature is defined as the average kinetic energy of the particles of a body. Hence, when a body is heated, the kinetic energy and consequently the speed of its particles increases.

This increase in particle speed is reversed when the system cools down. Recall that a physical change is easily reversible while a chemical change is not easily reversible.

As such, this increase of particle speed with temperature is a physical and not a chemical change.

Answer:

red beryl

Explanation:

Red Beryls = Density range is 2.63g/cm3 to 2.92 g/cm3

Rubies = Density Range is 3.9 g/cm3 to 4.1 g/cm3

Mass of stone = 4.35 g

Volume of solid = change in water level = 1.5 mL = 1 cm3

Relationship between mass, volume and density is given by;

Density = Mass / Volume

Density = 4.35 / 1.5 = 2.9 g/cm3

The density of the stone falls in the red beryls range hence it is a red beryl.

Answer:

The physician William Murrell was one of the first physicians to recognize the the clinical benefits of nitroglycerin in the treatment of the heart disease known as angina pectoris, a type of chest pain caused by reduced blood flow to the heart.

Explanation:

The physician William Murrell was one of the first physicians to recognize the the clinical benefits of nitroglycerin in the treatment of the heart disease known as angina pectoris, a type of chest pain caused by reduced blood flow to the heart. He also used nitroglycerin to treat and reduce high blood pressure. He used small diluted doses of nitroglycerin to treat patients with angina pectoris. Murrell published his treatment results in the article "Nitro-glycerine as a remedy for angina pectoris," in the journal The Lancet in 1879. Thereafter, the use of nitroglycerin as treatment procedure for angina pectoris soon became generally adopted by other physicians.

Nitroglycerin is a vasodilator which is a medicine that opens blood vessels in order to improve blood flow. Nitroglycerine acts to improve blood flow to the heart by opening up or dilating the coronary arteries in the heart, thereby reducing how hard the heart has to work in pumping blood round the body. It reduces preload by  dilating veins and reduces afterload moderately by dilating arteries.

Nitroglycerin comes in two forms: quick-acting forms and long-acting forms.

The quick-acting forms include tablets or oral sprays.

Long-acting forms include pills, tablets, skin ointment, and skin patches.

Answer:

The relative atomic mass of chlorine depends on the ratio between the abundance of these two naturally-occurring isotopes.

Explanation:

The relative atomic mass of an element is a weighted average of the atomic mass of its naturally-occurring isotopes. The relative abundance of each isotope gives its weight in this weighted average.

For these two naturally-occurring isotopes of chlorine:

[tex]\begin{array}{|c|c|c|}\cline{1-3} \text{Isotope} & \text{Atomic Mass} & \text{Relative Abundance}\\ \cline{1-3} ^{35}{\rm Cl} & \approx 34.968\; \rm Da} & \approx 0.758 \\ \cline{1-3} ^{37}{\rm Cl} & \approx 36.966\; \rm Da & \approx 0.242 \\ \cline{1-3}\end{array}[/tex].

[tex]\begin{aligned}&\text{relative atomic mass of Cl} \\ &= \text{atomic mass of $^{35}{\rm Cl}$} \times \text{relative abundance of $^{35}{\rm Cl}$} \\&\quad + \text{atomic mass of $^{37}{\rm Cl}$} \times \text{relative abundance of $^{37}{\rm Cl}$} \\ &\approx 34.968\; \rm Da \times 0.758 + 36.966\; \rm Da \times 0.242 \\ &\approx 35.45\; \rm Da \end{aligned}[/tex].

The relative abundance of [tex]^{35}{\rm Cl}[/tex] is much higher than that of [tex]^{37}{\rm Cl}[/tex]. Consequently, the relative atomic mass of the element [tex]\rm Cl[/tex] is closer to the atomic mass of [tex]^{35}{\rm Cl}\![/tex] than that of [tex]^{37}{\rm Cl}\![/tex].

Commutator is the answer

Explanation:

The commutator systematically converts the current direction between the rotor and the outer circuit. As the shaft revolves, the commutator converts the course of current in a winding. For a separate armature winding, when a cylinder has reached one-half perfect turn, the winding is now attached so that current passes through it in the reverse of the original direction.

Explanation:

Hydrocarbons are any of a class of natural substance intensifies made distinctly out of the components carbon (C) and hydrogen (H). The carbon particles consolidate to shape the structure of the compound, and the hydrogen molecules append to them in various arrangements.

Hydrocarbons are the chief constituents of oil and gaseous petrol. They fill in as powers and ointments just as crude materials for the creation of plastics, strands, rubbers, solvents, explosives, and modern chemical substances.

All of the compounds given are alkanes and they have the same general formula which is represented by CnH2n+2, where ‘n’ is the number of carbon atoms.

The coefficients and molar masses are used to calculate the amounts of molecules. Hence, option C is correct.

The smallest particle of a substance has physical and chemical properties of that substance. Molecules are made up of one or more atoms.

A molecule can be determined by how much is produced in a reaction through the coefficients and molar masses are used to calculate the amounts of molecules.

Hence, option C is correct.

Answer:

If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

Mass of Magnesium nitrate formed : 731.86 g

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

Mg + 2AgNO₃ → Mg(NO₃)₂ + 2 Ag

moles of silver nitrate, AgNO₃ = 9.87

mole ratio AgNO₃ : Mg(NO₃)₂ = 2 : 1, so mol Mg(NO₃)₂ :

[tex]\tt \dfrac{1}{2}\times 9.87=4.935[/tex]

mass of Mg(NO₃)₂(MW=148,3 g/mol) :

[tex]\tt mass=mol\times MW\\\\mass=4.935\times 148,3\\\\mass=731.86~g[/tex]

Answer:

Because as we move down the group size/ radius of atom increases due to increase in shells and screening effect. The hold of nucleus on valence electrons decreases and effective nuclear charge decreases so it is easy to remove electron from greater sized atoms as compared to smaller sized aroms.

Energy required to remove electron is ionization energy so greater sized atoms have low ionization energy.

Answer:

3 valence electrons

Explanation:

Because aluminum has three, that means three fluorines can bond. The make the formula AlF3, also known as aluminum trifluoride. Each of the fluorine atoms gets an electron to fill their shell, and the aluminum loses three, giving it a filled shell too (remember, aluminum has three extra electrons).

Answer:

The formation of the bond releases energy. This is because the individual hydrogen atoms are more unstable than when they are joined together. Stability brings about the release of energy, and this would be an exothermic reaction.
