Chemistry
1 answer:
Oxana [17]3 years ago
3 0

Answer:

CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)

Explanation:

According to this question, sodium carbonate reacts with sulfuric acid to form aqueous sodium sulfate, carbon dioxide and water. The balanced chemical equation is as follows:

Na2CO3(aq) + H2SO4(aq) → Na2SO4(aq) + CO2(g) + H2O(l)

- Next, split compounds that are aqueous into ions.

2Na+(aq) + CO32-(aq) + 2H+(aq) + SO42-(aq) → 2Na+(aq) + SO42-(aq) + CO2(g) + H2O(l)

- Next, we cancel out the spectator ions, which are ions that remain the same in the reactants and products side of a chemical reaction. The spectator ions in this equation are 2Na+(aq) and SO42-(aq).

CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)

- Hence, the balanced ionic equation is as follows:

CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)

Diamonds are measured in carats, and 1 carat=0.200 g. The density of diamond is 3.51 g/cm^3. What is the volume of a 5.0 - carat
Blizzard [7]

Answer:- Volume of the 5.0 carat diamond is 0.28cm^3 .

Solution:- It is a unit conversion problem. Need to convert carat to grams and then using grams and density the volume could easily be calculated.

We have 5.0 carat diamond and asked to calculate it's volume. Density of diamond is given as 3.51\frac{g}{cm^3} and 1 carat = 0.200 g. Let's do this step by step:

First step is the conversion of carat to grams:

5.0carat(\frac{0.200g}{1carat}) = 1.0 g

In second step, grams are converted to volume using the given density as:

volume=\frac{mass}{density}

volume=1.0g(\frac{1cm^3}{3.51g})

volume=0.28cm^3

So, the volume of the 5.0 carat diamond is 0.28cm^3 .

The third number on a fertilizer analysis indicates the amount of which element as being present in the product
Elza [17]
<span>Most fertilizer bags are marked with three numbers, which represent the amounts of the following chemicals: nitrogen, phosphorus, and potassium. The third number represents the amount of potassium in the fertilizer. All three of these chemicals are important for plants, but different plants require different amounts of these chemicals, so the label helps consumers determine which product to buy.</span>

How many joules are required to raise the temperature of 15.0 grams of water by 10 degrees Celsius?
tester [92]
The question is based on the Thermodynamic principle of Specific Heat Capacity. Now, Specific Heat Capacity refers to the amount of heat needed per unit mass t raise the temperature by one degree Celsius

The formula that can be used to find the answer is the following:
   Q = C · m · ΔT ( where Q is the heat added/required; C is the specific heat capacity [4.186 joule/gram °C]; ΔT is the change in temperature)

Based on the question, what needs to be found is Q, and what is known is that C = 4.186 J/g °C; m = 15 g;  ΔT = 10 °C

so,           Q = C · m · ΔT
                Q = (4.186 J/g °C) (15 g) (10 °C)
                Q = 627.9 J

Thus, the number of <span>joules required to raise the temperature of 15.0 grams of water by 10 degrees Celsius is 627.9 J</span>
