Answer:
B:A metal surface is acting as a catalyst and lowers the activation energy of bond breaking of hydrogen gas.
Answer:
0.826 g/cm³
Explanation:
density = mass/volume
density = 715 g/866 cm³
density = 0.82564 g/cm³
Rounded to 3 significant figures: 0.826 g/cm³
No, they do not. Carbon dioxide has a linear geometry because the lone pair and bond pair repulsion cancels out; however, water has a bent structure because only the oxygen atom possesses a lone pair which brings the bonding electron pairs closer.
Answer:
This is because the carbon dioxide gas that dissolved in the water is not very soluble. ... After the citric acid solution and baking soda react, carbon dioxide gas is formed, along with other products.
