Explanation:
1kg x 0,37=370gHCL
370g/36,5g/mol=10,137mol/kg
1l=1,185kg
10,137 x 1,185kg/l =12,0mol/l
(x/ml(12mol HCL)*12mol/L)/100ml=0,025mol/L
x=
Answer:
Hydrogen peroxide is a very pale blue liquid at room temperature. A French scientist called Louis Auguste Thenard discovered the compound in 1818. Hydrogen peroxide can easily break down, or decompose, into water and oxygen by breaking up into two very reactive parts – either 2OHs or an H and HO2:
Explanation:
Strawberry, bread, bananas/ lemonade, milk, water/ nitrogen, oxygen, carbon dioxide
Answer:
1280J are required.
Explanation:
Heat of fusion is defined as the amount of heat required to change its state from liquid to solid at its melting point at constant pressure.
As heat of fusion of gold is 64J/g, there are required 64J to melt 1g of gold at its melting point. The energy required to melt 20g is:
20g * (64J/g) =
1280J are required
answer: A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases.
