Explanation:

Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.

Answer:

3428.58 °C

Explanation:

We'll begin by converting 300 KPa to atm. This can be obtained as follow:

101.325 KPa = 1 atm

Therefore,

300 KPa = 300 KPa × 1 atm / 101.325 KPa

300 KPa = 2.96 atm

Next, we shall determine the temperature. This can be obtained as follow:

Number of mole (n) = 0.24 mole

Volume (V) = 25 L

Pressure (P) = 2.96 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Temperature (T) =?

PV = nRT

2.96 × 25 = 0.24 × 0.0821 × T

74 = 0.24 × 0.0821 × T

Divide both side by 0.25 × 0.0821

T = 74 / (0.24 × 0.0821)

T = 3755.58 K

Finally, we shall convert 3755.58 K to °C. This can be obtained as followb:

T(°C) = T(K) – 273

T(K) = 3755.58 K

T(°C) = 3755.58 – 273

T(°C) = 3428.58 °C

Thus, the temperature at which the gas was collected is 3428.58 °C

Answer: Thus there are 88.4 g of calcium bromide.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

Molar mass of = 40.1 (1)+ 2(79.9) = 199.9  

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

[tex]0.442=\frac{x}{199.9}[/tex]

[tex]x=88.4g[/tex]

Thus there are 88.4 g of calcium bromide.

Answer:

3.7mL is the volume of the object

Explanation:

To convert the mass of any object to volume we must use density that is defined as the ratio between mass of the object and the space that is occupying. For an object that weighs 7.9g and the density is 2.28g/mL, the volume is:

7.9g * (1mL / 2.28mL) =

Dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large.  The variety is because of selective breeding. Hence option 1 is correct.

Selective breeding is defined as the method by which people pick which male and female animals or plants would reproduce sexually and create offspring together in order to selectively acquire specific phenotypic features.  The goal of selective breeding is to produce cattle with desirable features that are strongly heritable and can thus be passed down from generation to generation.

Despite the fact that all dogs are descended from wolves, people have significantly changed the appearance of dogs through the use of artificial selection. Dogs have been bred for various desirable traits for ages, resulting in a vast variety of canines, from the little Chihuahua to the enormous Great Dane.

Thus, dogs are derived from wolves. Dogs are very diverse, varying in size from very small to very large.  The variety is because of selective breeding. Hence option 1 is correct.

Answer:

B; 4 L

Explanation:

From the Boyle’s law of gases, the volume occupied by a given mass of gas is inversely proportional to the pressure exerted by the gas

Mathematically, we have this as;

PV = K

Given;

P1 = 2 atm

V1 = 12 l

P2 = 6 atm

V2 = ?

We have that;

P1V1 = P2V2

2 * 12 = 6 * V2

V2 = (2 * 12)/6

V2 = 24/6

V2 = 4 L

Answer:

he Paleozoic, Mesozoic, and Cenozoic.

Explanation:

For this one, you can use the formula:

# of atoms = # of moles * Avogadro's number

# of atoms = (0.256 mol) * (6.02 * 10^23)

# of atoms = 1.54 * 10^23 atoms

Hope It helped you!

Atoms are the smallest unit of molecules. In 0.256 mol of iron, there are  1.54 × 10²³ atoms.

Atoms are small entities of the compound or the molecule that can be measured by Avogadro's number. The number of atoms can be given as the product of the moles and the Avogadro's number.

If 1 mole of iron = 6.02 × 10²³

Then, 0.256 moles = 0.256 × 6.02 × 10²³

Therefore,  1.54 × 10²³ atoms of iron are present in 0.256 moles.

Answer:

a, c are true statements

Explanation:

First statement concludes that only the slower stage or the rate deciding phase of the reaction allows for the rate law to be calculated. This is true

The second declaration is not valid in all regards, because we can not evaluate the correct rate law by just observing the net equation. It needs to be determined experimentally.

In the third statement, most of the bimolecular reactions are second order in general, since two reactants exist. Hence, it is true

The fourth declaration is wrong. To measure the rate of each elemental phase accompanying the response, we must observe the rates

Answer:

pH = 5.54

Explanation:

The pH of a buffer solution is given by the Henderson-Hasselbach (H-H) equation:

For acetic acid, pKa = 4.75.

We calculate the original number of moles for acetic acid and acetate, using the given concentrations and volume:

The number of CH₃COO⁻ moles will increase with the added moles of KOH while the number of CH₃COOH moles will decrease by the same amount.

Now we use the H-H equation to calculate the new pH, by using the new concentrations:
