Answer:
tissue
Explanation:
cell→tissue→organ→systems→organism
No, water does not heat up or cool down faster than soil. This is because soil has lower specific heat. Specific heat is how long it takes for a substance to <span>heat up or cool down</span>
Answer: i have not 1 idea
Explanation:
Answer:
Kp = 13.3
Explanation:
Partition coefficient is used to extract or purify a solute from a solvent selectively to avoid interference from other substances. The formula is:
Kp = Concentration of solute in organic solvent / Concentration of solute in H₂O
As the CH₂Cl₂ is containing 31mg, water is containing 4mg. Replacing in the formula:
Kp = (31mg/7mL) / (4mg/12mL)
<h3>Kp = 13.3</h3>
The theoretical yield of BaCO3 is 5.5
<h3>What is theoretical yield?</h3>
The theoretical yield is the yield calculated from the stoichiometry of the reaction. The equation of the reaction is;
Ba(NO3)2(aq) + Na2CO3 (aq) ------> BaCO3(s) + 2NaNO3(aq)
Number of moles of limiting reactant: 0.4 M × 70/1000 = 0.028 moles
Since the reaction is 1:1,om;y 1 mole of BaCO3 is formed. Hence, mass of BaCO3 = 0.028 moles × 197 g/mol = 5.5g
