Answer:
Explanation is given below.
Explanation:
The cold pack is applied on the injured part of body only the place where the type of injury is Sprain, swelling, or any other internal small injury. This is applied to lower the flow of blood in that particular area which reduces the further inflammation of that area.
For the applied pack the direction of the flow of the heat will be towards the cold pack which will absorb the heat of the injured part as the heat always flows from higher temperature to the lower temperature.
This method of treatment of an injury is the instant way of treating an injury which prevents further problem to the injury by reducing the blood flow to the site and cooling the affected area.

Answer:
25%
Explanation:
Half life means that 50% of the sample is gone at 3.3 years. This means that an additional 3.3 years (total 6.6 years) will reduce the sample a further 50% from the point at 3.3 years. In numbers, this means 50% of 50% (0.50*0.50), which is 25%.
Answer:
2) Gas molecules do not have preferred direction of motion, their motion is completely random. 3) Gas molecules travels in straight line. 4) The time interval of collision between any two gas molecules is very small. 5) The collision between gas molecules and the walls of container is perfectly elastic.
<h2>Hello!</h2>
The answer is: C2H6
<h2>Why?</h2>
First, we need to find the empirical formula of the compound:
Looking for the relative atomic mass for each element:
Finding the number of moles for each element:
Then, we need to determinate the mole ratio by dividing each result into the smallest number:
So, the empirical formula would be CH3
We are given the molar mass of the compound is equal to 30 g/mol
We need to compare the empirical formula molecular mass and the molecular formula molar mass in order to find the number of atoms of the compound:
Empirical formula molar mass:
Molecular formula molar mass = 30.0 g/mol
So, by dividing the molecular formula molar mass by the empirical formula molar mass we have the number of atoms of the compound:
Therefore,
The molecular formula will be: (CH3)2= C2H6
Have a nice day!
