The thrust is not the type of plate boundary.
The outer surface of the earth has been said to be composed of tectonic plates. The tectonic plates give rise to the shape of the zigzag puzzle. The puzzled plate boundaries are present in varying forms based on their shape.
The plate boundaries can be convergent. In this type of boundary, the earth's crust has been coming towards each other. They have been found between the Indian Plate and the Eurasian Plate.
The divergent plate boundary arises in the form of the earth crust moving away from each other. This will give rise to the mountain ranges.
The transform type of plate boundary has been formed when the tectonic plates slide over each other. This type of boundary has resulted in the San Andreas Fault.
The thrust is not the type of plate boundary.

Answer: The given statement is true.
Explanation:
When solid state of water changes directly into vapor state then this process is known as sublimation.
For example, when dry ice is placed at room temperature then it converts into vapor state without undergoing liquid state.
Also when we apply very high pressure or temperature at the solid state of water, it will change directly into vapor state.
Therefore, the statement ice does not need to melt into liquid water before it can return to the atmosphere as water vapor is true.
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.
What volume of oxygen gas is released at STP if 10.0 g of potassium chlorate is decomposed? (The molar mass of KClO3 is 122.55 g/mol.)
0.914 L
1.83 L
2.74 L
3.66 L
Answers
1. The balanced reaction would be:
2KClO3 --> 2KCl + 3O2
We are given the amount of potassium chlorate for the reaction. This will be the starting point of our calculation.
10.0 g KClO3 ( 1 mol KClO3 / 122.55 g KClO3) (3 mol O2 / 2 mol KClO3) = 0.1224 mol O2
V = nRT/P =0.1224 mol O2 x 273 K x 0.08206 atm L/mol K / 1 atm
V=2.74 L
Answer:
third option 2.74L

To determine whether a chemical formula represents a compound or element that will not combust, you need to consider the elements present in the formula and their respective properties.
How we can determine combustibility?
First, check if the formula contains only one type of element. If it does, then it represents an element, and the question of whether it will combust or not is irrelevant, as elements do not combust.
If the formula contains two or more different elements, then it represents a compound. To determine if the compound will combust, you need to look at the properties of its constituent elements.
Some elements, such as noble gases (e.g., helium, neon, argon), have very low reactivity and are unlikely to combust under normal conditions. Therefore, if the compound contains only noble gases, it is unlikely to combust.
Other elements, such as metals, are more reactive and can combust under certain conditions, such as exposure to heat or oxygen. Therefore, if the compound contains a metal, you need to check the reactivity of that metal to determine if the compound will combust.
Similarly, non-metals can also be combustible under certain conditions, such as exposure to heat or other reactive substances. Therefore, if the compound contains a non-metal, you need to check the reactivity of that non-metal to determine if the compound will combust.
Overall, to determine if a compound or element will combust, you need to consider the properties of its constituent elements and any external conditions that may affect its reactivity.
