Answer:
2HNO3 (aq) + Na2CO3 (aq) → 2NaNO3 (aq) + CO2 (g) + H2O (l)
Explanation:
This question is asking to write and balance an equation between between aqueous sodium carbonate (Na2CO3) and aqueous nitric acid (HNO3). The equation is as follows:
HNO3 (aq) + Na2CO3 (aq) → NaNO3 (aq) + CO2 (g) + H2O (l)
However, this equation is not balanced as the number of atoms of each element must be the same on both sides of the equation. To balance the equation, one will make use of coefficients as follows:
2HNO3 (aq) + Na2CO3 (aq) → 2NaNO3 (aq) + CO2 (g) + H2O (l)
Answer:
bio diesel
Explanation:
bio diesel is a recent development to supplement fossil fuels
The trend of electronegativity in the periodic table is increasing from left to right and from bottom to top. In the period 4 which is horizontal, the element which has the highest electronegativity is the right most element except the noble gas. This element is bromine.
B. The heat from the reaction turns water to steam, which runs a generator.
<h3>Explanation</h3>
Here's what's going on within a <em>typical</em> nuclear power plant.
- The fuel bundle undergoes fission to release heat.
- A coolant such as molten salt flows across the reactor and transfers heat away from the fuel.
- The coolant is then passed into a heat exchanger. Cold water goes through the heat exchanger to absorb the heat. The coolant cools down and is recycled. Water heats up and boils to produce steam.
The rest of this process resembles that of a coal power plant.
- Steam from the heat exchanger goes through a turbine, which drives a generator.
- Some water condenses and is recycled.
