Answer:

They are isotopes of each other ,meaning they are made of chemically the same substance but the number of neutrons is different.

Explanation:

Answer:Accounting for the sizes of protons, neutrons, and electrons, most of the volume of an atom—greater than 99 percent—is, in fact, empty space. ... The electrons that surround all atoms are negatively charged and cause atoms to repel one another, preventing atoms from occupying the same space.

The enthalpy of combustion per mole is -5397.7 kJ/mol.

The term combustion refers to a reaction in which  a substance is burnt in oxygen. Now we know that octane is a hydrocarbon and its combustion follows the general equation for the combustion of hydrocarbons.

[tex]2C_{8}H_{18} (g) + 25O_{2} (g)---- > 16CO_{2} (g) + 18H_{2} O(g)[/tex]

Given that the number of moles in one gram of octane is obtained from;

1g/114 g/mol = 0.0088 moles

If the burning of 0.0088 moles of octane produces  -47.5 kJ

Burning of 1 mole of octane would produce  1 mole * -47.5 kJ/0.0088 moles

= -5397.7 kJ/mol

We can now write is as;

[tex]2C_{8}H_{18} (g) + 25O_{2} (g)---- > 16CO_{2} (g) + 18H_{2} O(g)[/tex] ΔH = -5397.7 kJ/mol

Answer:  C. 6

Explanation:

According to the Law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction for photosynthesis is :

[tex]C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O+energy[/tex]

Thus the coefficient of water is 6.

Answer:

Both the initial and final substances are composed of atoms because all matter is composed of atoms. According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and type of atoms after the chemical change as were present before the chemical change.

The mole fraction of 195 g AlCl3 in 240 mL of water is 0.099.

Mole fraction is the ratio of the number of moles of a particular component to the total number of moles in the mixture. To determine the mole fraction of AlCl3, the mass of AlCl3 will be converted to moles and the number of moles of water must be determined. Since the amount of water used is expressed in volume, we will be using the density of water to determine the mass of water for a given volume.

Solving for the moles of AlCl3:

moles AlCl3 = mass AlCl3 / molar mass of AlCl3

moles AlCl3 = 195 g / 133.33 g/mol

moles AlCl3 = 1.4625 mol

Solving for moles of water:

A commonly used density of water is 1 g/mL.

240 mL of water * (1 g/mL) = 240 g of water

moles water = mass water / molar mass water

moles water = 240 g / 18.02 g/mol

moles water = 13.32 mol of water

Mole fraction = mol AlCl3 / ( mol AlCl3 + mol water)

Mole fraction = 1.4625 / {1.4625 +13.32)

Mole fraction of AlCl3 is 0.099

Answer:

Answer:

[tex]\boxed {\boxed {\sf 6.26 \times 10^{24} \ atoms }}[/tex]

Explanation:

To convert from moles to atoms, we must use a number called Avogadro's Number which is:

[tex]6.022\times10^{23}[/tex]

This number tells us the amount of atoms in a mole.

[tex]1 \ mole = 6.022\times10^{23} \ atoms[/tex]

To convert from moles to atoms, we must multiply Avogadro's number by the amount of moles.

We know there are 10.4 moles of Chlorine. Multiply 10.4 (molar amount) by 6.022 * 10²³ (Avogadro's Number)

[tex]10.4 \ mol *\frac{6.022\times10^{23} \ atoms }{ 1 \ mole}[/tex]

[tex]10.4 * 6.022\times10^{23} \ atoms[/tex]

[tex]1 \ mole = 6.022\times10^{23} \ atoms[/tex]

[tex]6.26288 \times 10^{24} \ atoms[/tex]

Let's round to 3 significant figures, because the original measurement 10.4, has 3 sig figs (1, 0, and 4)

For the number 6.26288, 3 significant figures is the hundredths place. The 2 in the thousandth place tells us to keep the 6 in the hundredths place.

[tex]6.26 \times 10^{24} \ atoms[/tex]

There are about 6.26 × 10²⁴ atoms in 10.4 moles of chlorine.

potassium hydroxide test

Explanation:

The test that uses color change to reveal oil-based paints is the potassium hydroxide test. The correct option is c.

The KOH (potassium hydroxide) approach is used to test for yeast in specimens. Potassium hydroxide acts as an enzymatic agent, breaking down detritus in a specimen, such as epithelial cells and WBCs, allowing yeast or pseudohyphae to be seen.

The potassium hydroxide prep test is used to detect fungal diseases on the skin or in the nails. A scrape of cells from the afflicted area is examined under a microscope for evidence of fungus. The potassium hydroxide skin lesions exam, fungal smear, or skin scraping are other names for the potassium hydroxide test.

Therefore, the correct option is the c, potassium hydroxide test.

By unit conversion,  the distilled water for dialysis in gallons is 68.69 gallons.

We need to know about unit conversion to solve this problem. The unit conversion can be used to convert a unit to another unit. It can be defined as

a = xb

where a is unit a, b is unit b and x is the constant of conversion.

From the question above, we know that

V = 2.6 x 10² liters

The unit conversion that we used is (1 gal = 3.785 liters)

V = 2.6 x 10² liters

V = 2.6 x 10² / 3.785 gal

V = 68.69 gallons

Answer:

See the answer below

Explanation:

From the equation, 1 mole of C requires 1 mole of O2 for a balanced reaction.

1 g of C will not exactly react with 1 g of O2 because the 1 g of each of the reactants contain different amounts of the substance.

The amount (in moles) of a substance is the mass of that substance divided by the molar mass.

Hence, 1 g of C will contain 1/12 moles of the substance while 1 g of O2 will contain 1/32 moles of the substance.
