The magma deep below Earth's surface cool slowly.Large crystals form results from magma cooling deep below Earth's surface. Therefore, option A is correct.
What is magma ?Magma is the molten or semi-molten natural material that gives rise to all igneous rocks. Magma can be found beneath the Earth's surface, and evidence of magmatism has been discovered on other terrestrial planets and natural satellites.
When magma slowly cools deep within the crust, the resulting rock is known as intrusive or plutonic. Because of the slow cooling, crystals can grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture. Individual crystals in phaneritic texture can be seen with the eye.
Intrusive igneous rocks form when magma slowly cools and solidifies beneath the Earth's surface. Large, well-formed crystals are found in intrusive igneous rocks such as granite, gabbro, diorite, and dunite.
Thus, option A is correct.

Which property or properties can change when the pressure of a gas changes?
Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand
Explanation:
According to this law, a gas's volume and temperature are directly correlated: When pressure is held constant, volume rises as temperature rises. The kinetic energy of the particles in a gas increases when it is heated, which causes the gas to expand.
What rules apply to gases?According to Boyle's Law, when the temperature and mass are both constant, the volume of a given volume of gas sustained at a constant temperature varies inversely with the applied pressure.
The quantity of gas particles, the volume of the container, and the temperature of the gas all affect the pressure of a gas that is confined. The pressure will rise as the amount of gas particles in a container increases. The pressure will rise as a container's volume increases.

A. they remain level since densities in both plates are equal.
B. they both push back down into the mantle
C. one plate rides over the other one and forms a trench
D.they buckle upward and form mountains
Answer:
D. They buckle upward and form mountains.

Whic statements explain why rocks weather at different rates? Check all that apply
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.

What is the molecule that formed between B and F?
Answer:
Hydrogen bond strengths range from 4 kJ to 50 kJ per mole of hydrogen bonds. In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

A student heats a 2.5 g sample of calcium carbonate in a test tube. What mass of calcium oxide remains in the test tube when the reaction is complete?
CaCO3(s) = CaO(s) + CO2(g)
Select one:
a. 1.4 g CaO
b. 2.1 g CaO
c. 2.5 g CaO
d. 1.0 g CaO
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

What are some ways that propane, butane, gasoline, diesel, and kerosene can be compared?
Answer:
Propane and butane are pure substances, which means that each one of them is made of only one type of molecule—propane molecules or butane molecules. In contrast, gasoline, diesel, and kerosene are not pure substances; they are mixtures of more than one substance.
Explanation:
Hope it is helpful...
Propane, butane, gasoline, diesel and kerosene are all hydrocarbons. They can be produced from petroleum. All these are used as fuels.
What are hydrocarbons ?Hydrocarbons are organic compounds containing C-C backbone and C-H bonds, These compounds are composed of carbons and hydrogens. Different function groups can be added to the hydrocarbons to form various organic compounds such as acids, esters , aldehydes, ketones etc.
Methane is the first hydrocarbon in the hierarchy based on number of carbons. Propane is third in this series since it contains 3 carbons and butane is 4th one. Gasoline, diesel and kerosene are all hydrocarbons with different carbon numbers.
All these are obtained as a byproduct of petroleum. These are used as fuel in vehicles and house holds. The difference in them is the number of carbon and hydrogen.

2. How many liters of propane gas (C3H8) will undergo complete combustion with 34.0 L of oxygen gas? ___ C3H8 (g) + ___ O2 (g → ___ CO2 (g + ___ H2O(g
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.

Aluminum nitrate reacts with sodium hydroxide to form a precipitate of aluminum hydroxide. What mass of aluminum hydroxide will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide?
Answer:
The mass of aluminum hydroxide that will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide is approximately 0.247 grams
Explanation:
The given parameters are;
The volume of 0.145 mol/L aqueous aluminum nitrate in the reaction = 35.5 mL
The volume of 0.215 mol/L aqueous sodium hydroxide in the reaction = 44.2 mL
The balanced chemical equation for the reaction is given as follows;
Al(NO₃)₃ (aq) + 3NaOH (aq) → Al(OH)₃ (s) + 3NaNO₃ (aq)
Therefore;
1 mole of Al(NO₃)₃, reacts with 3 moles of NaOH to form 1 mole Al(OH)₃, and 3 moles of NaNO₃
The number of moles of aqueous aluminum nitrate in the reaction = 35.5/1000 L × 0.145 mol/L = 0.0051475 moles
The number of moles of aqueous sodium hydroxide in the reaction = 44.2/1000 L × 0.215 mol/L = 0.009503 moles
Therefore, 0.009503 moles NaOH will react with 0.009503/3 moles Al(NO₃)₃ to form 0.009503/3 moles of aluminum hydroxide precipitate
The molar mass of aluminum hydroxide = 78 g/mol
Therefore, 0.009503/3 moles of aluminum hydroxide weighs 78 × 0.009503/3 = 0.247078 grams
The mass of aluminum hydroxide that will precipitate out ≈ 0.247 grams.
