How do you balance this equation?
Margarita [4]

Answer:

Al4C3 + 12H2O = 3CH4 + 4Al(OH)3

Explanation:

Not sure if any explanation is needed but always start with the most complex compound. In this case it is Al(OH)3. You can see that there is 4 Aluminiums on the other side so I would start by putting a 4 next to the Al(OH)3. This now gives me 12 Hydrogens and 12 Oxygens on the right side. I put a 3 next to the CH4 to balance the Carbons on the left side. This leaves me with 12 Oxygens and 24 Hydrogens on the right side. This ends up being perfect because I can put a 12 next to the H2O.

What amount of ice must be added to 250 g of water at 15°c to cool the water to 0°c and have no ice left
Juliette [100K]

Answer:

\mathbf{m= 47 \ g}

Explanation:

The heat needed to melt ice (q_1) + heat needed to cool water (q_2) = 0

m\Delta H_{fusion} + mc \Delta T = 0

m \times 333.55 J g^{-1} + 250 \ g \times 4.184 \ Jg^{-1 \ 0 } \times (-15.0 \ ^0 C) = 0

m \times 333.55 J g^{-1} =15690

m=\dfrac{15690 \ J }{333.55 J g^{-1} }

\mathbf{m= 47 \ g}

Why do atoms tend to be bonded to other atoms?
Aleks04 [339]

Answer:

Atoms are often more stable when bonded to other atoms

Explanation:

Like for example let's say ionic bonds..... Since one atom has to lose specific electrons to be stable and the other needs the electrons from the other atom to be stable.....
