A chef is testing out new iron cookware. He knows that iron has a specific heat of 445 J/kg°C. He heats a 2 kg iron skillet on stove for 5 minutes and finds that the
temperature of the iron skillet has increased by 250°C. What change in
temperature will the Chef observe when he heats his 4 kg iron skillet on the same
stove for the same amount of time?
A. An increase of 125°C
B. An increase of 250°C
C. An increase of 325°C
O D. An increase of 445°C

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material

The identities of substances are the same before and after which type of change

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
