Answer:
1.852 g of CO2 were produced in the chemical reaction
Explanation:
The problem is pretty simple. We can write down the chemical reaction that is involved to help us understand better what is going on in the process:
CaCO3 (aq) + HAc (aq) → CaAc (aq) + CO2 (g) + H2O (l)
Let's think this through: we have a tablet that has an active compound (CaCO3) and an inert substance that weighs 0.833 g. When we add 58.072 g of an acid solution (represented in the equation as HAc because we are not told specifically which acid is being added), CO2 is formed and released from solution as gas leaving us with an aqueous solution that weighs 57.053 g.
Having said that, we know that the only mass lost during the reaction is due to the formation of CO2 gas. Therefore, we sum the reactants (the tablet + the acid solution) and subtract the mass of the remnant solution. This value will indicate us the amount of CO2 formed:
0.833 g of the Tablet + 58.072 g from the Acid solution = 58.905 g
58.905 g of reactants - 57.053 g of remnant solution = 1.852 g of produced CO2.
Answer:
Fahrenheit
Explanation:
Scientists would use Kelvin, and occasionally, Celsius scales. They do this because they need a scale that goes Sub-zero. Sub-zero temperatures are below 0° centigrade or, in the United States, below 0° Fahrenheit.
Answer:
False. It is soluble in water.

Answer:</h2>
<h3>From the equation it is evident that 2 moles of Sodium metal produces 1 mole of hydrogen gas.</h3><h3>At STP 1mole of any gas occupies a volume of 22.4 litres.</h3><h3>Therefore, 7.80 gives---(7.80x1)/22.4 moles = 0.3482 moles</h3><h3>Since the mole ratio of Sodium to hydrogen is 2:1, then the number of moles of sodium that reacted is given by the following expression.</h3><h3>(0.3482 * 2) / 1 moles which gives 0.6964 moles.</h3><h3>The atomic mass of sodium is 23 thus the mass of sodium that reacted is given by:</h3><h3>mass=no. of Monogram</h3><h3>0.6964 * 23 = 16.02 grams.</h3><h2>
