Answer:
Water has high heat capacity to act as a thermal buffer against freezing.
The specific heat capacity of water = 4.2 joules per gram per degree Celsius or 1 calorie per gram per degree Celsius.
So, the vats of water will help in preventing the freezing of the materilas inside.
Explanation:
To calculate for the number of moles of SnO2 in the sample, we need the value of the products from the reaction. Since we do not have that data, we can assume that all of the sample is SnO2. Then, we are given the molecular mass of the sample, 151g/mol.
So, the number of moles is 3g / 151 g/mol = 0.0199 moles SnO2
Answer:
X is sodium hydroxide (caustic soda, NaOH)
y is sodium (Na)
Explanation:
The process of industrial electrolysis of sodium chloride solution by which chlorine and sodium hydroxide (caustic soda) can be produced is known as the chlor-alkali process as follows;
2NaCl + 2H₂O → Cl₂ + H₂ + 2NaOH
Given that the compound X is formed from a element y which is in the form of a pellet, we have;
The element in the above reaction that can exist as pellet is the silver white metallic sodium pellet
Therefore, the compound X is NaOH and the element y is sodium, Na.
