Explanation
To find the mass from the given number of moles of the compound or molecule or atom.Use this formula
mass = moles x MM
where MM is the molar mass of the compound .To find the molar mass of CaCl2, consider the number of atoms of each element in the formula then multiply the number of elements with their atomic masses then finally add all the molecular weight.
CaCl2 has 1 Ca atom , 2 Cl atoms.
Ca = 1 x 40.07 = 40.07
Cl = 2 x 35.45 = 70.9
40.07 + 70.9 = 110.97 g / mol
mass = 0.89 x 110.97 = 98.76 g
Answer
98.76 g
I would explain that by stirring the sugar it would dissolve and go into the drink. I would show her the dissolved sugar by boiling the lime drink and collecting the excess sugar from boiling theliquid
Answer:
Each of these organelles performs a specific function critical to the cell's survival. For example, biochemical reactions in a cell's mitochondria transfer energy from fatty acids and pyruvate molecules into an energy-rich molecule called adenosine triphosphate (ATP).
Explanation:
Potential energy U= k*Q*q/r
doubling the charge Q doubles the potential energy. Since this will just be converted into kinetic energy u will double tht
P1=836kPa
T1=54.7+273=327.7K
P2=836+79.9=915.9kPa
T2=?
T2=T1*P2/P1
=327.7*915.9/836
=359K=86 degree celsius
