Answer:


D) Heat flows from the copper cube to the iron cube.  


Step-by-step explanation:


The reason comes from the second law of thermodynamics:


Heat energy will flow spontaneously from an area of high temperature to one of low temperature.


When you bring two objects of different temperature into contact, heat energy always moves from the hotter to the cooler object.


The copper cube is hotter than the iron, so heat flows from the copper cube to the iron cube.


here hope this helps

What is the volume, in liters, of 576 grams of so2 gas at stp?
katen-ka-za [31]
The volume  in  liters  of  576 grams  of SO2  gas  at STP  is   calculated as below

calculate the moles of SO2 = mass/molar  mass

= 576 g/64 g /mol  = 9 moles

At  STP  1mole =22.4 L
what  9 mole =? liters

by cross  multiplication

= 22.4 L x  9 moles/ 1moles = 201.6 liters

Balance the following chemical equation (with all steps)
WARRIOR [948]

Answer:

Balanced chemical equation:

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Explanation:

Chemical equation:

Al + H₂SO₄  →  Al₂(SO₄)₃ + H₂

Balanced chemical equation:

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Steps:

Let balance the SO₄ first.

Al + 3H₂SO₄  →  Al₂(SO₄)₃ + H₂

There are three H₂ on left so put the coefficient three on right too.

Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

Two Al  on right and one on left so we will put the coefficient two on left.

2Al + 3H₂SO₄  →  Al₂(SO₄)₃ + 3H₂

All atoms are correctly balanced.
