A solution containing a mixture of 0.0333 M0.0333 M potassium chromate ( K2CrO4K2CrO4 ) and 0.0532 M0.0532 M sodium oxalate ( Na2C2O4Na2C2O4 ) was titrated with a solution of barium chloride ( BaCl2BaCl2 ) for the purpose of separating CrO2−4CrO42− and C2O2−4C2O42− by precipitation with the Ba2+Ba2+ cation. The solubility product constants ( KspKsp ) for BaCrO4BaCrO4 and BaC2O4BaC2O4 are 2.10×10−102.10×10−10 and 1.30×10−61.30×10−6 , respectively. A) Which barium salt will precipitate first? O BaC204 O BaCrO4
B) What concentration of Ba2+ must be present for BaCrO4 to begin precipitating? Number [Ba2+]=
C) What concentration of Ba is required to reduce oxalate to 10% of its original concentration? Number 2+
D) What is the ratio of oxalate to chromate (IC204CrO4) when the Ba2 concentration is 0.0050 M? Number C, O Cro,

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
