Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock
Sloan [31]

Material from this sedimentary rock ever forms igneous rock, <u>Option D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form </u><u>igneous rock.</u>

Sedimentary rocks are shaped from pre-existing rocks or pieces of soon-as-dwelling organisms. They form from deposits that collect on this planet's floor. Sedimentary rocks regularly have special layering or bedding.

Igneous rock, or magmatic rock, is one of the 3 primary rock kinds, the others being sedimentary and metamorphic. Igneous rock is shaped via the cooling and solidification of magma or lava. The magma may be derived from partial melts of existing rocks in either a planet's mantle or crust.

Every day on his ride to school, Max sees some sedimentary rock. He starts to wonder: Could material from this sedimentary rock ever form igneous rock?

A. No, igneous rock can only form out of other igneous rocks. Sedimentary rock cannot change into igneous rock.

B. No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but the sedimentary rock is only at Earth’s surface.

C. Yes, if the sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

D. Yes, if the sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.

Please help 35 points
stealth61 [152]
First one is balanced because all of the elements in reactant and product have equal number of atoms.

second one is not balanced therefore you need to add coefficient to balance it. so its CaCl2 + 2NaHCO3 = CO2 + CaCO3 + H2O + 2NaCl

both of them seem double replacement reaction

Hope it helps!

What will be the equilibrium temperature when a 245 g block of lead at 300oC is placed in 150-g aluminum container containing 82
loris [4]

Answer:

The correct approach is "12.25°C".

Explanation:

Given:

Mass of lead,

mc = 245 g

Initial temperature,

tc = 300°C

Mass of Aluminum,

ma = 150 g

Initial temperature,

ta = 12.0°C

Mass of water,

mw = 820 g

Initial temperature,

tw = 12.0°C

Now,

The heat received in equivalent to heat given by copper.

The quantity of heat = m\times s\times t \ J

then,

⇒ 245\times .013\times (300-T) = 150\times .9\times (T-12.0) + 820\times 4.2\times (T-12.0)

⇒             3.185(300-T) = 135(T-12.0) + 3444(T-12.0)

⇒             955.5-3.185T=135T-1620+3444T-41328

⇒                         43903.5 = 3582.185 T

⇒                                  T = 12.25^{\circ} C
