Answer:

option 1. Two substances in a mixture differ in density and particle size. These properties can be used to separate the substances. These properties can be manipulated in order to have a better separation between the two substances.

Explanation:

Answer:

Two substances in a mixture differ in density and particle size. These properties can be used to separate both of them using the separating funnel or using filtration (filter paper).

Explanation:

Since their densities are different, one substance should float above the other in the mixture which allows for the separating funnel to let the substance sinking below (with the heavier density) to flow out first before changing the beaker to let the lighter substance flow out.

The substance with a bigger particle size would not be able to pass through the filter paper unlike the substance with the smaller particle size as the filter paper's pores is not big enough for it to pass through, separating both substances (with one on the paper and the other outside the filter paper, preferably in the beaker placed below the paper).

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Answer:

0.17×10⁻³ mol

Mass = 0.00476 g

Explanation:

Given data:

Number of molecules of N₂ = 1 ×10²⁰ molecules

Number of moles of N₂ = ?

Mass in gram of N₂ = ?

Solution:

1 mole of any substance contain 6.022×10²³ molecules

1 ×10²⁰ molecules× 1 mol /6.022×10²³ molecules

0.17×10⁻³ mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.17×10⁻³ mol × 28 g/mol

Mass = 4.76×10⁻³  g

Mass = 0.00476 g

Answer:

12 protons and 12 neutrons are present in Mg and

38 protons and 50 neutrons are present in Sr

Explanation:

Answer:

For ²⁴Mg

1. Proton number = 12

2. Neutron number = 12

For ⁸⁸Sr:

1. Proton number = 38

2. Neutron number = 50

Explanation:

For ²⁴Mg:

1. Determination of the number of proton.

The atomic number of an element is simply defined as the number protons in the atom of the element. The atomic number of ²⁴Mg is 12 since no two elements have the same atomic number.

Atomic number = 12

Proton number = Atomic number

Proton number = 12

2. Determination of the Neutron number.

Mass number = 24

Proton number = 12

Neutron number =?

Mass number = Proton + Neutron

24 = 12 + Neutron

Collect like terms

Neutron = 24 – 12

Neutron number = 12

For ⁸⁸Sr:

1. Determination of the number of proton.

The atomic number of ⁸⁸Sr is 38.

Atomic number = 38

Proton number = Atomic number

Proton number = 38

2. Determination of the Neutron number.

Mass number = 88

Proton number = 38

Neutron number =?

Mass number = Proton + Neutron

88 = 38 + Neutron

Collect like terms

Neutron = 88 – 38

Neutron number = 50

Explanation:

Chemical then thermal because the carbon emissions produce heat

Then kinetic because there is energy transfer then electric because that's the finished result

Explanation:

Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.

Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.

An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.

Intermolecular forces are classified into five types namely,

Between ions and polar dipole molecules, ion-dipole forces exist.

Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.

This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.

Thus, this is the reason of using types of intermolecular forces present.

Answer:

1.4 g CaO

Explanation:

Given data:

Mass of calcium carbonate = 2.5 g

Mass of Cao remain in tube = ?

Solution:

Chemical equation:

CaCO₃    →     CaO + CO₂

Number of moles of CaO:

Number of moles = mass/molar mass

Number of moles = 2.5 g/ 100 g/mol

Number of moles = 0.025 mol

now we will compare the moles of CaO with CaCO₃.

                    CaCO₃        :          CaO

                        1              :             1

                    0.025         :         0.025

Mass of CaO:

Mass = number of moles × molar mass

Mass = 0.025 mol × 56 g/mol

Mass = 1.4 g

Answer:

1.4g CaO

Explanation:

The correct order of the chemical elements from highest to lowest electronegativity is: C. Br, Zn, Sc, Ca, K.

Electronegativity refers to a measure of the ability of an atom of a chemical element to attract any shared pair of electrons.

Generally, the electronegativity of a chemical element typically increases across the period from left to right.

In Chemistry, the electronegativity of some of the chemical element are:

Explanation:

Explanation:

Weathering occurs one of three ways: through physical processes such as freezing and thawing, because of live organisms whose roots break rocks or through chemical processes that occur when carbon dioxide in the soil and air and mixes with water and specific minerals in rocks to form a weak acid that reduces rocks into silt, soil and sediment.

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.
