Answer:
<em>The first three options given out of the five options are correct.</em>
- <em>It collects chemical data.
</em>
- <em>It records real-time sampling data.
</em>
- <em>It processes and stores chemical data.</em>
Explanation:
An electronic air sampler is a device that is used by people to check apprehension of contamination having individuals with the help of certain volume of air sampling.
The Device is used for recording the chemical data of contamination and the real-time data is sampled and recorded and the data is processed and stored. The air sampling is done in two ways.
P is pressure V is volume T is temperature N is number of moles and R is 8.314
According to Charles' law for ideal gases, at constant pressure, the volume and temperature of a given mass of gas with same number of moles are directly proportional to each other. This means, if volume increases then temperature will also increase whereas, if volume decreases then temperature will also decrease. For this reason, a small increase in volume will increase the temperature of the gas.
Therefore,
Volume ∝ Temperature in Kelvin scale.
V ∝ T
Answer:
Explanation:
The question states that the chemical equations should be balanced and the phases should also be indicated. The abbreviations of the phases have been indicated in the question with
i) (s) meaning the compound is in solid
ii) (aq) meaning the compound is in aqueous form
iii) (l) meaning the compound is in liquid
iv) (g) meaning the compound is in gaseous form
Balanced chemical equation is that in which the number of individual atoms on the reactant side is equivalent to the number of the same individual atoms on the product side.
Only the answer (the balanced chemical equations) will be written below.
A) This reaction is balanced
Mg(s) + Br₂(l) ⇒ MgBr₂(s)
B) P₄(s) + 5O₂(g) ⇒ P₄O₁₀ (s)
C) Ba(OH)₂(aq) + 2HNO₃(aq) ⇒ Ba(NO₃)₂(aq) + 2H₂O
D) Cr₂O₃(s) + 3C(s) ⇒ 2Cr(s) + 3CO(g)
