Answer:
462g
Explanation:
First, let us calculate the molar mass of Cu(CN)2. This is illustrated below:
Molar Mass of Cu(CN)2 = 63.5 + 2(12+14) = 63.5 + 2(26) = 63.5 + 52 = 115.5g/mol
Number of mole of Cu(CN)2 given from the question = 4moles
Mass = number of mole x molar Mass
Mass of Cu(CN)2 = 4 x 115.5
Mass of Cu(CN)2 = 462g
Answer: 5.84x10^4
Explanation: You start with (9.00x10^26 atoms)x(1 mol/ 6.022x10^23)x(39.10 g/1 mol)
Answer:
The energy consumed by animals in the form of glucose is conserved because it is transformed into chemical energy as carbon dioxide is produced during respiration.
Explanation:
There's no diagram....but I kinda figured it from the description.
Maple syrup, which comes from the sap of maple trees, contains water and natural sugars. It's a clear, brown liquid and the sugars can’t be separated by <span>filtration. It should be categorized as a homogeneous mixture since the sugar is homogeneously </span>dispersed<span> or mixed in water. It is completely dissolved resulting to uniform properties of the mixture.</span>
B. A mixture of flour, sugar, eggs, and butter is baked to become a cake.
