Answer:
Magnesium bromide, MgBr2, and water, H2O.
Explanation:
Hello!
In this case, since HBr is an acid and Mg(OH)2 is a base, an acid-base reaction is undergone, by which a salt and water are produced as neutralization products:
However, it need to be balanced since two bromine atoms are produced, therefore we write:
Thus, the products are magnesium bromide, MgBr2, and water, H2O.
Best regards!

The volume increases to 1.009 L.
<em>V</em>= <em>V</em>_0 +βΔ<em>T</em>
The thermal expansion coefficient (β) of water changes with temperature, so we must calculate the volume change over small (10 °C) intervals.
20 °C to 30 °C: <em>V</em> = 1 L + 0.000 207 L·°C^(-1) × 10 °C = 1.002 07 L
30 °C to 40 °C: <em>V</em> = 1.002 07 L + 0.000 303 L·°C^(-1)] × 10 °C = 1.005 10 L
40 °C to 50 °C: <em>V</em> = 1.005 10 L + 0.000 385 L·°C^(-1)] × 10 °C = 1.008 95 L
The volume increases by about 9 mL when the temperature increases from 20 °C to 50 °C.
Yes, it <span>is possible for a particular element to have various number of neutrons, and that would make it have an isotope. </span>
