Oxygen because it is one the table of elements and none of the others are.
Answer:
612 K
Explanation:
From the question given above, the following data were obtained:
Initial temperature (T₁) = 306 K
Initial pressure (P₁) = 150 kPa
Final pressure (P₂) = 300 kPa
Volume = 4 L = constant
Final temperature (T₂) =?
Since the volume is constant, the final (i.e the new) temperature of the gas can be obtained as follow:
P₁ / T₁ = P₂ / T₂
150 / 306 = 300 / T₂
Cross multiply
150 × T₂ = 306 × 300
150 × T₂ = 91800
Divide both side by 150
T₂ = 91800 / 150
T₂ = 612 K
Thus, the new temperature of the gas is 612 K
Answer:
NaHCO3 + HCl ——-> NaCl + H2O + CO2
Explanation:
A neutralization reaction is a chemical reaction between an alkali and an acid to give salt and water as the product.
In the case of carbonates and bicarbonates, an additional product is added. This additional product is carbon iv oxide.
Hence a neutralization reaction involving an acid and a carbonate or bicarbonate would yield water, carbon iv oxide and a salt as the product.
When brioschi reacts with hydrochloric acid, the products are sodium chloride, water and carbon iv oxide.
The equation of the reaction is shown below:
NaHCO3 + HCl ——> NaCl + H2O + CO2
Heat can be transferred from one material to another by direct touch (conduction), by differences in density of a fluid (temperature difference), and by RADIATION
Answer:
- <u><em>Both fitth electons are located on a 2p orbital.</em></u>
Explanation:
The electrons fill the orbitals of the atom in increasing order of energy level. Using Aufbau's mnemonic rule you can find the order of filling:
- 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ . . .
Thus, the firs two electrons are located on the 1s orbital, the next two electrons are on the 2s orbital, and the <em>the fifth, electron of </em>both <em>boron and carbon is located </em>on a 2p orbital.
