The correct statements are b, c, and e.
A hypothesis is defined as a tentative or proposed explanation for the occurrence of any phenomenon.
It is usually based on a very less number of pieces of evidence and provides the first step for further classification.
The hypothesis must be testable so that it can be accepted or rejected on the basis of scientific methods.
Thus, the correct statements are b, c, and e.
<h3>Answer:</h3>
C6H12O6
Explanation:
To find empirical formular you write out the element
Carbon Hydrogen Oxygen
3.96 769 5.28
then u althrough divide by their atomic numbers
3.96÷ 12 769÷1 5.28÷16
=0.33 =769 =0.33
also divide althrough by the lowest number
the lowest number is 0.33 so we use it to divide
0.33÷0.33. 769÷0.33. 0.33÷0.33
= 1 = 2 = 1
empirical formular= CH2O
To find the Molecular formular
Molecular number = molar mass
(CH2O)n = 182
(12+1×2+16)n = 182
30n = 182
n = 6
therefore the Molecular formular is C6H12O6
If your collecting at STP, you can use the converting constant of 22.4 litters/ One Mole. So, you would have convert ml to L and then go from there.
Also, when working with grams, you usually need to know the gas your working with. As one mole equals the atomic mass of an element in grams.
The number of moles and the mass (in kg) of copper(II) carbonate needed to decompose in order to produce 1.500 kg of copper(II) oxide, where CO2 is the other product.
