Answer: 12.5 moles NaNO3
Explanation: solution attached.
First balance predict the products
Na+ Mg( NO3)2 => Mg + NaNO3
Next balance the chemical equation
2 Na + Mg(NO3)2 => Mg + 2 NaNO3
Solve for the moles of Na
175 g Na x 1 mole Na/ 14 g Na
Next compare the mole ratios of Na and NaNO3 based from the balanced equation.
2 moles Na : 2 moles NaNO3
Mass of calcium carbonate (in grams) can be dissolved by 4.1 g of Hcl is 5.62g.
<h3>What is balanced equation?</h3>
A balanced equation is one for a chemical reaction in which the overall charge and the number of atoms for each component are the same for both the reactants and the products. In other words, the mass and charge of both sides of the reaction are equal.
The reaction between calcium carbonate and hydrochloric acid can be expressed through the chemical reaction,
CaCO₃ + 2HCl --> CaCl₂ + H₂O + CO₂
Hydrochloric acid has a molecular weight of 36.45 g/mol compared to calcium carbonate's molecular weight of 100 g/mol. According to the equation above, 72.9 g of hydrochloric acid may dissolve 100 g of calcium carbonate.
x = (4.1 g HCl)(100 g CaCO3 / 72.9 HCl)
x = 5.62 g.

One of the key differences is that of the waysin which electrons are utilized. Metals form ionic solids, as well as metallic solids. This has todo with the hold that metals have on their electrons. This hold is quite weak, ranging from no desire to hold them, as observed in the large number of ionic solids, to a low affinity as observed in metallic solids, such as copper wire, tin sheets, and iron bars. Nonmetals have a desire for electrons, ranging from quite strong, as observed in ionic solids, to moderately weak, as observed in countless molecular and covalent solids, such as sucrose, napthalene, and diamond. This difference in types of solids revolves around the electron conduction among the atoms/ions of the solids. This conduction is highest in metallic substances and lowest in nonmetallic substances.

When the cold areas are warmed up, their density drops and they arise. Finally, they cool, sink and replicate the manner all over anew. The decision is a circular motion or current in the running part of the mantle. This method is described as convection.
<h3>Explanation:</h3>
The great point to retain is that heat flows from heated areas to cool areas. In the asthenosphere, you have unusual areas that are warmer than others. Convection is also subject for currents in the air. Hot air (a gas) increases near the equator and continues to the poles, where it cools, grows thicker and descends.
