Magnesium is a group 2 metal which exists as a number of isotopes and forms many compounds.

Chemistry

HACTEHA [7]4 years ago

Answer:

Traces of sodium impurity

Explanation:

Metal ions are identified by a characteristic colour imparted to flame by the metal ion solution. Various metals have various colours which they impart to a flame.

The energy of a flame is not sufficient for the excitation of electrons of Mg to a higher energy level. As a result of this, Mg do not give any color in Bunsen flame.

However, a few tinges of yellow-orange colour which is characteristic of sodium metal do appear when magnesium ions are exposed to a flame as a consequence of traces of sodium impurity in the magnesium ion solution.

muminat

Answer:

Explanation:

The missing image is attached below.

The objective of this question is to draw the major product formed from the diagram attached below.

From the diagram attached, we will see the reaction of a tertiary alkyl halide together with a weak nucleophile (ch3ch2oh) undergoing a nucleophilic substitution (SN₁) mechanism to yield a racemic mixture(i.e., compound that is not optically active but contains an equal amount of dextrorotatory and levorotatory stereoisomers) as a product.

Three examples of simple distillation​
hram777 [196]

Answer:

1. Water can separate from salt solution by simple distillation

2. Simple distillation happens through a process heating and cooling liquids in order to separate the purify them, first, a liquid is heated producing a vapor, then, that vapor is cooled in a small tube called a condenser in order to form a separate liquid that liquid, sometimes referred to as the distillate, falls from the condenser into a separate container, the process works because it to liquids in the original vaporized a different point, meaning, the vapor that is created is comprised entirely of just one of the liquids in order for a simple work the 2 liquids boiling point must have been between at least 25 degrees Celsius about 77 degrees Fahrenheit

Explanation:

ig u can get info from the 2. to help u srry I don't feel like correcting my grammar but I hope that makes sense :)

If the pressure, volume, and temperature of a gas are known, which can most lik
morpeh [17]

Answer:

The molar amount of the gas.

Explanation:

If the pressure, volume, and temperature of a gas are known than molar amount can be determine.

Formula:

PV = nRT

P = pressure

V = volume

R = general gas constant

T = temperature

n = number of moles

Example:

V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K

n = PV/RT

n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K

n = 2 / 22.413 /mol

n = 0.09 mol

Common salt besides being used in kitchen can also be used as the raw material for making.
Anon25 [30]

Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.

The overall balanced reaction for washing soda preparation:

2NaCl + CaCO3 → Na2CO3 + CaCl2

NaCl is sodium chloride or common salt

Na2CO3 is sodium carbonate or washing soda

CaCO3 is calcium carbonate or limestone

The overall balanced reaction for baking soda preparation:

NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl

Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.

NH3 is ammonia

CO2 is carbon (II) oxide

Britta traveled 1250 km on her road trip and used 209 L of gasoline, filling her tank atan average of 1.14 euros per liter. Pier
icang [17]

Answer:

  • Britta paid more per kilometer driven

Explanation:

<u>1) Britta:</u>

  • Distance traveled: 1,250 Km
  • Gasoline used: 209 liter
  • Gasoline price: 1.23 euros / liter

Cost per km = total cost of gasoline / distance traveled

Cost per km = gasoline used × gasoline price / distance traveled

Cost per km = 209 liter × 1.14 (euro / liter) / 1,250 km =  0.19 euro / km

<u>2) Pierce:</u>

  • Distance traveled: 1,405 km
  • Gasoline used: 175 liter
  • Gasoline price = 1.23 euros / liter

Cost per km = 175 liter × 1.23 (euro / liter) / 1,405 km =  0.15 euro / km

<u>3) Comparison:</u>

  • 0.19 > 0.15 ⇒ Britta paid more per kilometer driven
