Yes! Conservation of mass applies for all just like conservation of energy. The explanation; if you weigh the burnt stuff its weight might be greater or less than its original weight, and this never violates the cons. of mass law as if you actually counted the masses of all the products like CO2 and reactants like O2, that is if you keep your system a closed system, you will actually get the same masses before and after the burning process.
The diagram shows an age structure for the population of Thailand in the 1960s.From the diagram we can conclude that -The population has a large proportion of youth under the age of 25.The population is in a period of rapid growth.The population has a large proportion of seniors over the age of 65.
Explanation:
The diagram shows an age structure for the population of Thailand in the 1960s. The following conclusions about the population are supported by the age structure
- The population has a large proportion of youth under the age of 25.
- The population is in a period of rapid growth.
- The population has a large proportion of seniors over the age of 65.
From the diagram given we can see that during the year 1960 the population of the individual under the age group of 25 years was more which clearly indicates that the population is under the period of rapid growth .From the image we can also conclude that as the age of an individual increases from 25 to 65 and then 105 years the number of individuals decline(A steep decline in the population is visible as the individual age starts increasing from 65-105 years)
Answer: evaporation i believe
Methane (CH4) is symmetrical because the bonds connecting hydrogen with carbon form a tetrahedron (pyramid) shape as shown in the attached image.
