Answer:

1.22 mL

Explanation:

Let's consider the following balanced reaction.

2 AgNO₃ + BaCl₂ ⇄ Ba(NO₃)₂ + 2 AgCl

The molar mass of silver chloride is 143.32 g/mol. The moles corresponding to 0.525 g are:

0.525 g × (1 mol/143.32 g) = 3.66 × 10⁻³ mol

The molar ratio of AgCl to BaCl₂ is 2:1. The moles  of BaCl₂ are 1/2 × 3.66 × 10⁻³ mol = 1.83 × 10⁻³ mol.

The volume of 1.50 M barium chloride containing 1.83 × 10⁻³ moles is:

1.83 × 10⁻³ mol × (1 L/1.50 mol) = 1.22 × 10⁻³ L = 1.22 mL

At STP, it is at 273 K and 1.00 atm.
Use PV=nRT to and solve for n (number of mol of N2)
1.00 atm • 4.40L / 0.08206 Latm/molK • 273 K = 0.196 mol N2
There are two mol of N2 for every two mol of NH4NO2 (the number of mol of both are equal)
Find the molar mass of NH4NO2 = 64.1 g
Multiply the number of mol by the molar mass
0.196 mol • 64.1 = 12.6 g NH4NO2

How many grams of a solution that is 50% by weight NaOH
kkurt [141]

Answer:

12 g

Explanation:

We want to prepare 1 L of a 0.15 M NaOH solution. The moles of NaOH required are:

0.15 mol/L × 1 L = 0.15 mol

The molar mass of NaOH is 40.00 g/mol. The mass corresponding to 0.15 mol is:

0.15 mol × (40.00 g/mol) = 6.0 g

The starting solution is 50% by weight. The mass of solution that contains 6.0 g of NaOH is:

6.0 g NaOH × (100 g solution/50 g NaOH) = 12 g solution

malfutka [58]

The answer to this question depends on the specific context in which urban and industrial development is taking place. However, in general, these sectors often practice improper and mismanaged sewage systems due to a lack of understanding or awareness of the potential environmental impacts of their activities.

Urban and Industrial development:
An agrarian economy becomes a manufacturing economy through the process of industrialization. Manual and specialised employees are replaced by assembly lines and mass production. In the past, this process has sparked urbanisation by generating economic expansion and employment possibilities that entice people to live in cities.

When one or more factories are built in an area, urbanisation usually starts since there is a great need for factory workers. The factories are subsequently followed by other enterprises, like those that produce buildings, sell goods online, and offer services to consumers. As a result, there are more occupations created and housing needs are increased, creating an urban area.

In many cases, engineers and other technical professionals are present in these sectors but are not consulted or involved in the decision-making process regarding sewage systems. This can lead to a situation in which the systems are not designed or operated in an environmentally sustainable manner.
