Answer:

Scientists believe the batteries (if that is their correct function) were used to electroplate items such as putting a layer of one metal (gold) onto the surface of another (silver), a method still practiced in Iraq today.

mixer [17]

Answer:

34.6 cm³

Explanation:

<em>A chemistry student needs 55.0 g of carbon tetrachloride for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of carbon tetrachloride is 1.59 g/cm³. Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.</em>

Step 1: Given data

  • Mass of carbon tetrachloride (m): 55.0 g
  • Density of carbon tetrachloride (ρ): 1.59 g/cm³

Step 2: Calculate the required volume of carbon tetrachloride

Density is an intrinsic property of matter. It can be calculated as the quotient between the mass of the sample and its volume.

ρ = m/V

V = m/ρ

V = 55.0 g/(1.59 g/cm³)

V = 34.6 cm³

The chemistry student should pour 34.6 cm³ of carbon tetrachloride.

It is dangerous to have over 1.3 ppm of copper (Cu) in drinking water. A small town investigates their water supply and finds th
lianna [129]

Answer:

The town should find a new source of water.

Explanation:

Step 1: Convert the mass of copper to milligrams

We will use the conversion factor 1 g = 1000 mg.

0.002 g × (1000 mg/1 g) = 2 mg

Step 2: Convert the mass of solution to kilograms

We will use the conversion factor 1 kg = 1000 g.

1000 g × (1 kg/1000 g) = 1 kg

Step 3: Calculate the concentration of Cu in ppm (mg/kg)

2 mg/1 kg = 2 ppm

This is over 1.3 ppm, so the town should find a new source of water.

Match each element or compound with the appropriate symbol or molecular formula. Carbon dioxide CO2 carbon o oxygen Н H water с
Furkat [3]

Answer:

Carbon dioxide ---> CO₂

Water ----> H₂O

Carbon ---> C

Oxygen ----> O₂

Hydrogen ----> H₂

Explanation:

The molecular formula of an element or compound is a formula which represents the composition of a molecule of that element or compound. It consists of the formula representing the atoms present as well as the number of atoms of each element innthe compound written as subscript innthe formula of the element or compound.

The molecular formula of the given elements and compounds are given below:

Carbon dioxide ---> CO₂

Water ----> H₂O

Carbon ---> C

Oxygen ----> O₂

Hydrogen ----> H₂

The molecular formula of carbon dioxide shows that in a molecule of carbon dioxide, there are two atoms of oxygen and one atom of carbon present in a molecule of carbon dioxide.

The molecular formula of water shows that are two atoms of hydrogen and one atom of oxygen present in a molecule of water.

The molecular formula of carbon shows that there are one carbon atoms in a molecule of carbon.

The molecular formula of oxygen shows that there are two oxygen atoms in a molecule of oxygen gas.

The molecular formula of hydrogen shows that there are two molecules of hydrogen in a molecule of hydrogen gas.
