Answer:

<u>  Translation:</u>

Classify the following elements into metals, nonmetals, metalloids, or gases, noble : fluorine, sulfur, nitrogen, chlorine, magnesium, helium, sodium, bromine, silicon, tellurium.

  • Metals: magnesium and sodium.
  • Nonmetals: fluorine, chlorine, bromine, sulfur and nitrogen.
  • Metalloids: silicon and tellurium.
  • Noble gases: helium.

Explanation:

Metals: They occupy the left and central areas of the Periodic Table; therefore, they constitute a majority group of the elements.

Nonmetals: They are located in the upper right region of the Periodic Table.

Within the Periodic Table, the metalloids lie diagonally from boron to polonium. Items above on the right are nonmetals, and items below on the left are metals.

The noble gases are located in group 18 of the Periodic Table.

Answer:

fluorine: it is a gas at room temperature

sulfur: it is a metal

nitrogen: it is a diatomic gas

chlorine: it is a halogen

helium: it is a gas

sodium: alkali metal

magnesium: metal

bromine: halogen

silicon: metalloid

tellurium: it is a semi-metal

Explanation:

the grouping of the chemical compounds respect a location in the periodic table, and this classification exists since all the compounds have different behaviors, different melting and boiling temperatures and even different valence, oxidation, atomic masses.

How many grams of copper (II) nitrate would be produced from 0.80 g of copper metal reacting with excess nitric acid?
zaharov [31]

Answer:

m_{Cu(NO_3)_2}=2.36 gCu(NO_3)_2

Explanation:

Hello!

In this case, since the chemical reaction between copper and nitric acid is:

2HNO_3+Cu\rightarrow Cu(NO_3)_2+H_2

By starting with 0.80 g of copper metal (molar mass = 63.54 g/mol) and considering the 1:1 mole ratio between copper and copper (II) nitrate (molar mass = 187.56 g/mol) we can compute that mass via stoichiometry as shown below:

m_{Cu(NO_3)_2}=0.80gCu*\frac{1molCu}{63.54gCu} *\frac{1molCu(NO_3)_2}{1molCu} *\frac{187.56gCu(NO_3)_2}{1molCu(NO_3)_2} \\\\m_{Cu(NO_3)_2}=2.36 gCu(NO_3)_2

However, the real reaction between copper and nitric acid releases nitrogen oxide, yet it does not modify the calculations since the 1:1 mole ratio is still there:

4HNO_3+Cu\rightarrow Cu(NO_3)_2+2H_2O+2NO_2

Best regards!

A dose of aspirin of 5.0 mg per kilogram of body weight has been prescribed to reduce the fever of an infant weighing 8.5 pounds
Tanya [424]
<h3><u>Answer</u>;</h3>

19 mg

<h3><u>Explanation</u>;</h3>

dose = 5.0 mg/kg  

weight of infant = 8.5 pounds

Convert 8.5 pounds to kg: 8.5 pounds = 3.86 kg

Therefore;

The dose to give the infant is:  

= (5.0 mg/kg) x (3.86 kg)

= 19.3 mg  

<u>≈ 19 mg</u>
