Write a full chemical equation for the reactions between magnesium and sulfuric acid

melamori03 [73]

Answer:

magnesium + hydrochloric acid → hydrogen gas + magnesium chloride

explanation:

the nitrogen in HNO3 is in the +5 oxidation state and is easily reduced. The reduction would result in the oxidation of the hydrogen gas, forming the water once again.The sulfur in H2SO4 is also in its highest oxidation state, +6.

Hope this helps :)

You are given a cube of lead that is 1.000 cm on each side. The density of lead is 11.35. How many atoms of lead are in the samp

aliya0001 [1]

11.35 g atoms of lead are in the sample.

What does density mean?

The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
Divide the number of objects by the area's measurement to determine density.
A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.

We can calculate the volume of the cube by cubing the side of the cube.

Volume of cube = ( 1.000 cm)³

= 1.000 cm³

We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.

= ( 1.000 cm³) ( 11.35 $\frac{g}{cm^{3} }$ )
