What is the balanced equation for the reaction of magnesium with hydrochloric acid?

Back

Mg + 2 HCl -> MgCl2 + H2

Front

What is La Niña?

Back

La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the Pacific Ocean, which can affect weather patterns globally.

Front

How many atoms are in one formula unit of Na3PO4?

Back

One formula unit of Na3PO4 contains 5 atoms (3 Na, 1 P, 4 O).

Front

What is the coefficient of NO when balancing the equation N2 + O2 -> NO?

Back

The coefficient is 2, so the balanced equation is N2 + O2 -> 2 NO.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when neutrons emitted from a nuclear fission reaction strike other nuclei, causing them to split and release more neutrons.

Front

What is the role of HCl in the reaction with magnesium?

Back

HCl provides hydrogen ions (H+) that react with magnesium to produce hydrogen gas and magnesium chloride.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What are the products of the reaction between magnesium and hydrochloric acid?

Back

The products are magnesium chloride (MgCl2) and hydrogen gas (H2).

Front

What is the effect of La Niña on marine life?

Back

La Niña increases marine life due to colder, nutrient-rich waters along the Pacific coast.

Front

How do you calculate the total number of atoms in a compound?

Back

To calculate the total number of atoms, multiply the subscript of each element by the number of formula units and sum them up.
