Double replacement :

2Na₃PO₄+3CaCl₂⇒6NaCl + Ca₃(PO₄)₂

<h3>Further explanation</h3>

1. A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

2. Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

3. Combination/syntesis : 2 or more reactants combine to form a new compound

4. Decomposition : the reactant is decomposed into 2/more products

If we look at the reaction options available, all of them can be included in the double replacement reaction, but we only choose the reaction from Sodium phosphate and Calcium chloride which leads to options: C because it is balanced (from the number of atoms in the same reactant and product) and is in accordance with the chemical formula of each compound (both products and reactants)

One cup of milk contains 318 mg of calcium. A student drinks 0.318 L of milk in one day. How many mg of calcium does the student
loris [4]

Answer:

426 mg = 4.26 x 10² mg

Explanation:

1 cup = 237.6 mL x 1 L/1000 mL = 0.2376 L

We divide the liters of milk the student drinks into the volume in liters of a cup to calculate the number of cups the student drinks per day:

number of cups per day = 0.318 L/0.2376 L = 1.34 cup

Now, we multiply the number of cups by the amount of calcium that a cup of milk has:

amount of calcium = 1.34 cup x 318 mg = 426 mg = 4.26 x 10² mg

Therefore, the student gets 426 mg (or 4.26 x 10² mg) of calcium in one day.
