False, many chemicals can be toxic to the drainage systems, and can make their way into the ocean harming sea life.
Answer:
92.9 °C
Explanation:
Step 1: Given data
- Initial volume (V₁): 450. mL
- Initial temperature (T₁): 55.0 °C
- Final volume (V₂): 502 mL
Step 2: Convert 55.0 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 55.0 + 273.15 = 328.2 K
Step 3: Calculate the final temperature of the gas
If we assume constant pressure and ideal behavior, we can calculate the final temperature of the gas using Charles' law.
T₁/V₁ = T₂/V₂
T₂ = T₁ × V₂/V₁
T₂ = 328.2 K × 502 mL/450. mL = 366 K = 92.9 °C
Answer:
(i) Cl₂ is a limiting reactant
(ii) The amount of excess reactant = 4.8 g
Explanation:
Br₂(g) + Cl₂(g) → 2 BrCl(g) ---------------------------(i)
Calculation of no. of moles
Using mole ratio method to find the limiting reactant and Excess reactant.
So 
is a limiting reactant and Br₂ is excess reactant.
The amount of excess reactant = 0.18 - 0.15 = 0.03 mole = 4.8 g
Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.
