Answer:
The answer to your question is: 1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃
Explanation:
Single replacement reaction:
2Fe + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂
M Fe = 55.8 g/mol
M H₂SO₄ = 98.1 g/mol
M Fe₂(SO₄)₃ = 399.9 g/mol
M H₂ = 2.0 g/mol
Fe₂(SO₄)₃ = 3.21 x 10¹² mol
Fe₂(SO₄)₃ = ? g
1 mol of Fe₂(SO₄)₃ ----------------- 399.9 g/mol of Fe₂(SO₄)₃
3.21 x 10¹² mol Fe₂(SO₄)₃ -------- x
x = (3.21 x 10¹² x 399.9 ) / 1
x = 1.28 x 10 ¹⁵ g of Fe₂(SO₄)₃
I was going to say third quarter but since its not an answer maybe First quarter?
Answer:
the answer is According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge. The electrons are like plums in a pudding.
Explanation:
Water stores energy more efficiently than air under equal conditions.
It requires more energy to heat water than it does to heat air because water has a significantly larger heat capacity and specific heat than air. Compared to air, which has a specific heat of 1.005 J/g degreesC, water has a specific heat of 4.186 J/g degreesC.
Specific heat:
The amount of heat required to raise the temperature per unit mass is known as specific heat capacity. The heat in Joules required to increase the temperature of 1 gram of sample by 1 Kelvin or degree Celsius is often stated. Water is an excellent temperature regulator since it has a very high specific heat capacity.
