Cake is a fluffy tasty dessert with frosting, while pie is a crusty, hardish dessert with fillings such as cherries or apples. Can I plz have brainliest?
Answer:
Explanation:
Mixture: is combination of one or more substances mix together.
• The properties of the mixture are not same and contains the properties of all those component present in it.
• it is a combination of one or more Pure substances and can be separated by simple physical methods.
• it have varying boiling and melting point
Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.
The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.
Examples are:
• Salt water is mixture of water and NaCl and can be separated by physical mean.
• Air: mixture of gases
Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.
The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture
Examples is
• mixture of salt and sand
• mixture of water and sand
Mass of MnO2 = 25 g
The reaction would be 3MnO2 + 4Al --> 3Mn(s) + 2Al2O3
Molar mass of Al = 26.982 g/mol
Molar mass of MnO2 = 54.938 + 2(15.999) = 86.936 g/mol
Calculating the moles = 25 / 86.936 = 0.2876 mol.
Mole ratio MnO2 and Al considering the equation = 3 mol of MnO : 4 mol of Al
Calculating the moles of Al = 0.2876 mol MnO2 x (4 mol of Al / 3 mol of MnO)
Number of moles of Al = 0.3834
Getting the mass in grams as asked = 0.3834 mol x 26.982 g/mol = 10.34 grams.
Answer:
The answer is 102.3!
Explanation:
you get this by multiplying 34.1 x 3 to get 102.3.
Wondering why you multiply 34.1 times 3?
WELLLLLLLLLLL...
when you get 1 mole of h202, you get 34.1 so if you ask for 3 moles of H202, you get 102.3!
