H+ refer to acid solution HCI (aq). the presence of H+ ions in a solution cause : b. a reaction with magnesium to release hydrogen gas.
the equation H+ react with magnesium to release hydrogen gas is Mg + 2H + --> Mg(2+) H2(g)
hope this help
Answer:
The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 
Explanation:
Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:

In this case, you know:
Replacing:

Solving:

<u><em>The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 </em></u>

Answer:
328 ml
Explanation:
We have given final volume =575.2 ml=0.575 L
Final concentration = 0.8012 M
We know that moles of copper(II) nitrate = final volume ×final concentration =0.8012×.0575=0.4606 moles
We have to find initial volume
So initial volume
Answer:
Anhydride, any chemical compound obtained, either in practice or in principle, by the elimination of water from another compound. Examples of inorganic anhydrides are sulfur trioxide, SO3, which is derived from sulfuric acid, and calcium oxide, CaO, derived from calcium hydroxide
