Answer: Heat energy is another name for thermal energy.

Explanation:

As thermal energy comes from moving particles, it is a form of kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature.

Answer:

When a substance heats up, the rise in temperature makes these particles move faster and bump into each other. Thermal energy is the energy that comes from the heated up substance. The hotter the substance, the more its particles move, and the higher its thermal energy.

The part that is missing from the product side = 6 oxygen atoms.

Photosynthesis is the process by which green plants traps in energy from the sun, through their chlorophyll, which they use in the manufacture of sugar with oxygen as a by-product.

The balanced equation of photosynthesis;

6CO2 + 6H2O + (energy) → C6H12O6 + 6O2

From the equation given,

6CO2 + 6H20 - CH1206+?

The missing part of the product = 6O2 (-6 oxygen atoms)

4. A material that cannot conduct heat and electricity is called an INSULATOR. Among the given options, WOOD is a poor conductor of heat i.e. it cannot withstand hear. Iron, gold and copper are all metals, hence, very good conductors.

5. Matter which constitutes all substances tend to react with one another, however, when the observed trait or characteristic is called a CHEMICAL PROPERTY.

6. Physical property of matter can either be intensive or extensive. INTENSIVE PHYSICAL PROPERTY is that characteristic or trait of matter that does not depend on the amount. Example is temperature, density etc

7. PHYSICAL PROPERTY is the property of matter that can be observed or perceived with our senses easily without changing its chemical composition or nature. Example of physical property is melting.

8. Matter exists in three states; solid, gas and liquid. In the GASEOUS state of matter, particles are relatively far apart or scattered and practically independent of each other. This allows gas to be able to diffuse.

One mole of or 392 g of chromium sulphate gives 3 moles of sulphate ions. Thus 30 g of chromium gives 0.15 moles of sulphate ions or 9.39 ×10²² ions.

Ions are charged substances formed by electron lose or gain by an atom. If an atom gain an electron it acquire one unit of  negative charge and if it lose an electron it acquires a positive charge.

The ionization of chromium sulphate is written as follows:

[tex]Cr_{2}(SO_{4})_{3} \rightarrow 2Cr^{3+} + 3SO_{4}^{2-}[/tex]

Hence, one moles of chromium sulphate forms 3 moles of sulphate ions. One mole of chromium sulphate is 392.18 g/mol. Thus number of moles 20.4 g of the compounds is 20.4 / 392.18 = 0.052 moles.

The number of moles of sulphate ions produced by 0.052 moles of chromium sulphate is calculated as follows:

0.052 × 3 = 0.15 moles.

One mole of sulphate ion contains 6.022 × 10 ²³ions. Thus number of ions in 0.15 moles is 0.15 ×6.022 × 10 ²³ =  9.39 ×10²² ions.

This problem is providing the mass of gummy bears which are assumed to contain 13 g of sucrose, which undergoes combustion and produces -214.3kJ of heat according to the following:

In chemistry, when a fuel undergoes combustion, a reaction with oxygen, it produces carbon dioxide and water in a complete combustion. In such a way, with the given reaction, we can write the heat of reaction as -11,286 kJ per mole of reaction:

[tex]\Delta H=-11,286\frac{kJ}{mol\ rxn}[/tex]

Which means that if we need the total heat released by 13 g of sucrose, one must apply the following dimensional analysis including this fuel's molar mass (342.3 g/mol):

The molar concentration of benzene is 0.05mol/L

Data;

molar mass of benzene = 78g/mol

molar mass of ethanol = 46g/mol

mole fraction of benzene is

[tex]mole fraction = \frac{moles of benzene}{total mole}[/tex]

Let's substitute the values and find the mole fraction of benzene

[tex]_yC_6H_6 = \frac{\frac{0.005}{78} }{(\frac{0.005}{78})+ (\frac{1-0.005}{46}) }\\ _yC_6H_6 = 0.00295[/tex]

Answer:

Option D. Electron clouds with a total of 7 electrons.

Explanation:

For an atom to be neutral (i.e having a charge of zero), the number of protons and electrons must be equal.

Thus, to know which option is correct, we shall determine the number of protons and electrons in the nitrogen atom as given in the question above.

From the question given above, we obtained the following:

Atomic number = 7

Mass number = 14

Number of protons =?

Number of electrons =.?

Next, we shall determine the number of protons in the nitrogen atom as follow:

Atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically,

Atomic number = proton number

Atomic number = 7

Therefore,

Number of protons = 7

Next, we shall determine the number of electrons in nitrogen atom as follow:

Since the atom is neutral (i.e having a charge of zero), the number of protons and electrons are equal i.e

Number of protons = number of electrons

Number of protons = 7

Therefore,

Number of electrons = 7

Thus, the nitrogen atom must have 7 electrons in order for it to be neutral.

**** Check ****

Charge of atom = Proton – Electron

Charge = 0

Proton = 7

Electron = 7

Charge of atom = Proton – Electron

0 = 7 – 7

0 = 0
