Yes, carbonic acid is hygroscopic, meaning it has the ability to attract and hold water molecules from the surrounding environment. This property is due to the presence of hydrogen bonds in the structure of carbonic acid, which allows it to interact with water molecules. As a result, carbonic acid can easily dissolve in water and form a solution. **

Polylactides are hydrophilic, meaning they have an affinity for water and can absorb moisture from the environment. This property makes them suitable for applications such as absorbable sutures and drug delivery systems. However, their hygroscopic nature can also lead to degradation and loss of mechanical properties if not properly controlled during processing and storage. **

Silica gel is more hygroscopic than NaOH. This means that silica gel has a greater ability to absorb and hold onto water molecules from the surrounding environment. This property makes silica gel a popular desiccant for controlling humidity and moisture in various products and environments. On the other hand, while NaOH can also absorb moisture, it is not as effective as silica gel in this regard. **

Not all apartments in rental properties are typically tested for Legionella. Testing for Legionella is not a standard requirement for rental properties, but some landlords or property managers may choose to conduct testing as a precautionary measure. If there is a suspected or confirmed case of Legionnaires' disease in a rental property, testing for Legionella may be recommended to ensure the safety of the residents. **

Housing cooperatives allocate their apartments based on a variety of criteria, including financial stability, community involvement, and housing needs. Prospective members are often required to demonstrate their ability to pay the cooperative's monthly fees and contribute to the maintenance of the property. Additionally, some cooperatives prioritize applicants who are committed to participating in the cooperative's decision-making processes and community activities. Finally, housing cooperatives may also consider the specific housing needs of applicants, such as family size or accessibility requirements, when allocating apartments. **

Social housing apartments are allocated to individuals with a WBS (Waiting List for Social Housing) certificate based on their level of need and eligibility. The WBS certificate is issued to individuals who have applied for social housing and have been assessed as meeting the eligibility criteria. The allocation process takes into consideration factors such as household size, income, and specific needs, with priority given to those in the greatest need. Once an individual is allocated a social housing apartment, they are required to sign a tenancy agreement and pay rent based on their income. **

If the government controlled the apartments, there could potentially be a housing shortage. Government control could lead to inefficiencies and lack of incentives for investment and maintenance, which could result in a decrease in the overall housing supply. Additionally, government control may also lead to bureaucratic red tape and slow decision-making processes, further exacerbating the shortage. However, it is also possible that government control could lead to more equitable distribution of housing and better affordability for low-income individuals, potentially mitigating the shortage in some areas. **

In a cooperative housing society, the allocation of apartments typically works through a membership system. Individuals or families who want to live in the cooperative must become members by purchasing shares in the cooperative. The number of shares purchased often determines the size or type of apartment that the member is eligible for. The allocation process may also take into account factors such as seniority, need, or other criteria set by the cooperative's governing body. Once an apartment becomes available, it is allocated to a member based on these factors and the member's shareholding in the cooperative. **
