Answer:
The volume of cupboard is 2.0043 m³.
Explanation:
Given data:
width of cupboard = 1.31 m
length of cupboard = 0.9 m
height of cupboard = 1.70 m
Volume = ?
Solution:
Volume = length × width × height
Volume = 0.9 m × 1.31 m × 1.70 m
Volume = 2.0043 m³
The volume of cupboard is 2.0043 m³.
Pressure<span> with </span>Height<span>: </span>pressure<span> decreases with increasing </span>altitude<span>. The </span>pressure<span> at any level in the </span>atmosphere<span> may be interpreted as the total weight of the </span>air<span> above a unit area at any </span>elevation<span>. At higher elevations, there </span>are<span> fewer </span>air<span> molecules above a given surface than a similar surface at lower levels.</span>
B and C are the correct answers
Balanced equation
So we see from inspection that H is not balanced. And by balancing H we have to add 2(NO2) and 2H
So the balanced equation is;
2HNO2 + CaCO3 = H2CO3 + Ca(NO2)2
