What is true about the statement is that it is equal to the same root as the formation of the carbon
Answer:
LiOH + KCl —> LiCl + KOH
Explanation:
LiOH + KCl —> LiCl + KOH
The equation is balanced since we have the same number atoms of the different elements on both side of the equation
Answer:
142.82 g
Explanation:
The following data were obtained from the question:
Volume of water = 12 mL
Volume of water + gold = 19.4 mL
Density of gol= 19.3 g/cm³
Mass of gold =.?
Next, we shall determine the volume of the gold. This can be obtained as follow:
Volume of water = 12 mL
Volume of water + gold = 19.4 mL
Volume of gold =.?
Volume of gold = (Volume of water + gold) – (Volume of water)
Volume of gold = 19.4 – 12
Volume of gold = 7.4 mL
Finally, we shall determine the mass of the gold as follow:
Note: 1 mL is equivalent to 1 cm³
Volume of gold = 7.4 mL
Density of gol= 19.3 g/cm³ = 19.3 g/mL
Mass of gold =?
Density = mass /volume
19.3 = mass of gold /7.4
Cross multiply
Mass of gold = 19.3 × 7.4
Mass of gold = 142.82 g
Therefore, the mass of the gold pebble is 142.82 g
Answer:
4.13 moles of Fe will be produced in the reaction
Explanation:
To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.
The reaction is:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.
We assume, the Fe₂O₃ in excess, so we propose this rule of three
3 moles of CO can produce 2 moles of Fe
Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe
Answer:
TRUE
Explanation:
The youngest rocks on the ocean floor are located at the oceanic ridge, an underwater mountain range formed from the spreading of tectonic plates
