Answer:
Urban sprawl is the development in urban areas
Due to which people are migrating from rural areas to urban areas to get the jobs or their income sources due to the opportunities.
So, as population is increasing in the urban areas. The food consumption and water consumption will also increase.
So, this is how urban sprawl affect water consumption.
Balanced chemical reaction:
MgSO₄(aq) + Sr(NO₃)₂(aq) → Mg(NO₃)₂(aq) + SrSO₄(s).
Ionic reaction:
Mg²⁺(aq) + SO₄²⁻(aq) + Sr²⁺(aq) + 2NO₃⁻(aq) → Mg²⁺(aq) + 2NO₃⁻(aq) + SrSO₄(s).
Net ionic reaction:
Sr²⁺(aq) + SO₄²⁻(aq) → SrSO₄(s).
Magnesium sulfate (MgSO₄), strontium nitrate (Sr(NO₃)₂ and magnesium nitrate (Mg(NO₃)₂) are soluble in water. Strontium sulfate (SrSO₄) is not soluble in water.
This chemical reaction is double displacement reaction - cations and anions of the two reactants switch places and form two new compounds.
Lets find the electronegativity difference between the bonded atoms;
C-H = 2.6-2.2 = 0.4
C-F = 4.0-2.6 = 1.4
F-F = 4.0-4.0 = 0
H-O = 3.4-2.2 = 1.2
Here the electronegativity difference is highest for C-F bond hence C-F bond is most polar.
Answer:
1.23 × 10³ N
Explanation:
Step 1: Given and required data
- Mass of the person (m): 125 kg
- Acceleration due to the gravitational force (g): 9.81 m/s²
Step 2: Calculate the force acting between the Earth and a 125-kg person standing on the surface of the Earth
We will use Newton's second law of motion.
F = m × g
F = 125 kg × 9.81 m/s²
F = 1.23 × 10³ N
