Answer:
The answer is 375.54 g of AgBr
Explanation:
Mass (g) = Concentration (mol/L) x volume (L) x Molecular Weight of AgBr (g/mol)
Mass = 2M x 1L x 187.77 g/mol
Mass = 375.54g
The number of oxygen atoms are 6 atoms
<u><em>Explanation</em></u>
According to the law of mass conservation the number of reactant atoms is equal to number of product atoms.
For given equation to obey the law of mass conservation it need to be balanced as below
4 Al + 3 O₂ → 2 Al₂O₃
Al₂O₃ is the product,therefore the number of oxygen atom
= coefficient in front of Al₂O₃ × subscript of O
=2 x 3 = 6 atoms
Answer:
3.54 mol
Explanation:
Step 1: Given data
- Temperature (T): 45.00 °C
Step 2: Convert "T" to Kelvin
We will use the following expression.
K = °C + 273.15
K = 45.00°C + 273.15 = 318.15 K
Step 3: Calculate the number of moles (n) of argon gas
We will use the ideal gas equation.
P × V = n × R × T
n = P × V/R × T
n = 2.50 atm × 37.0 L/(0.0821 atm.L/mol.K) × 318.15 K = 3.54 mol
The human activity creating water pollution and depletion are uses of fertilizers, detergents and chloro flouro carbon many other things.
<h3>What is water pollution?</h3>
Water pollution is defined as the contamination of water bodies, usually as a result of human activity, in such a way that their lawful uses are harmed.
The activities of human that creating water pollution are:
- Uses of fertilizers
- Harmful chemical in agriculture
- Detergents for washing clothes
- Wastes from industries
And depletion in the ozone layer are due to halogen source gases, which contain chlorine and bromine atoms, are produced by human activities. These emissions into the atmosphere eventually contribute to ozone depletion in the stratosphere.
Hence human activities are uses of fertilizers, detergents and many other things.
