The magma is heated and becomes less dense by the core moving it toward the crust.

Explanation:

Magma is a molten or partially molten rock form. Magma consists of silicate liquid, although carbonate and sulfide melts occur as well. It moves either to depth or to Earth’s surface and is ejected as lava. Suspended crystals and fragments of un-melted rock get transported in the magma dissolved volatiles may separate as bubbles and some liquid get crystallize during movement.

Several interrelated physical properties determine the characteristics of magma, including chemical composition, viscosity, dissolved gases, and temperature.Magma also form igneous rock.

Therefore the magma is heated and becomes less dense by the core moving it toward the crust.

What specifically determines how much energy is available in a molecular

HACTEHA [7]

C The number and types of bonds within the molecule.

Explanation:

In a molecule, the number and types of bonds present determines the amount of available energy therein.

When bonds are broken or formed, energy is usually released.

Elements combine with one another in order to attain stability in this state.
Through this process, they form bonds by attraction.
Where atoms exchange their valence electrons by losing or gaining it, electrovalent bonds form.
In covalent molecules, electrons are usually shared between atoms.
An attraction result from this type of interaction.
The bond formed stores energy in the process.
When bonds are broken, energy is usually released. The energy accrues when the bond was being formed.
In molecules, we have covalent bond.

When 91.5 g of isopropyl alcohol which has an empirical formula of C3H8O is burned in excess oxygen gas, how many grams of H2O a

Kobotan [32]

Answer:

109.7178g of H2O

Explanation:

First let us generate a balanced equation for the reaction. This is illustrated below:

2C3H8O + 9O2 —> 6CO2 + 8H2O

Next we will calculate the molar mass and masses of C3H8O and H20. This is illustrated below:

Molar Mass of C3H8O = (3x12.011) + (8x1.00794) + 15.9994 = 36.033 + 8.06352 + 15.9994 = 60.09592g/mol.

Mass of C3H8O from the balanced equation = 2 x 60.09592 = 120.19184g

Molar Mass of H2O = (2x1.00794) + 15.9994 = 2.01588 + 15.9994 = 18.01528g/mol

Mass of H2O from the balanced equation = 8 x 18.01528 = 144.12224g

From the equation,

120.19184g of C3H8O produced 144.12224g of H20.

Therefore, 91.5g of C3H8O will produce = (91.5 x 144.12224) /120.19184 = 109.7178g of H2O

Diamonds are composed of __________ in a ___________lattice. A. silicon, trigonal planar B. quartz, octahedral lattice C. carbon

Nata [24]

Diamonds are composed of carbon in a tetrahedral lattice. That is option C.

<h3>What is a diamond?</h3>

A diamond of defined as an allotrope or one of the major forms of the element, carbon in nature.

These carbon atoms are arranged within the diamond in a face centered cubic tetrahedral lattice shape.

Therefore, Diamonds are composed of carbon in a tetrahedral lattice.

musickatia [10]

Answer:

$T_2=335.42K=62.27^oC$

Explanation:

Hello,

In this case, by using the general gas law, that allows us to understand the pressure-volume-temperature relationship as shown below:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

Thus, solving for the temperature at the end (considering absolute units of Kelvin), we obtain:

$T_2=\frac{P_2V_2T_1}{P_1V_1}=\frac{1.8L*0.75atm*(25+273.15)K}{1.2L*1.0atm} \\\\T_2=335.42K=62.27^oC$

Best regards.
