crimeas [40]

Answer:

2. Copper (II) carbonate plus sulfuric acid produces copper (II) sulfate and carbon dioxide and water.

  • We need the "II" after copper to specify what charge it is. It's +2 because carbonate is -2.

3. Calcium hydroxide plus carbon dioxide gas produces calcium carbonate and water.

The density of a certain type of steel is 8.1 g/cm3. What is the mass of a 124 cm3 chunk of this steel? Show
posledela

Mass of the steel is 1004.4 g

  • density of a substance can be regarded as the ratio of the mass of that substance to that of it's volume.

  • Mass of substance can be regarded as the quantitative measure of inertia, it can be simply explained as a fundamental property of all matter

<em> We can express this mathematically as ;</em>

  • Density=  \frac{ mass  }{volume  }

Given :

Density of this steel= 8.1g/cm3

Mass=  124 cm^{3}

If we make Mass subject of formula,

Mass= ( density *volume)

Then let us substitute the values into the expression

Mass= (124*8.1)

= 1004.4 g

Therefore, mass of the steel is 1004.4 g
