The normal range of creatinine in human blood is between 0.50 mg/dL and 1.1 mg/dL. The patient's blood has a concentration of 0.0082 g/L. Let's convert that value into mg/dL.
We kwnot that there are 1000 mg in 1 g. And there are 10 dL in 1 L. We have to use those conversions.
1000 mg = 1 g 10 dL = 1 L
0.0082 g/L = 0.0082 g/L * 1000 mg/g = 8.2 mg/L * 1 L/ (10 dL) = 0.82 mg/dL
0.0082 g/L = 0.82 mg/dL
0.50 mg/dL < 0.82 mg/dL < 1.1 mg/dL
Answer: The concentration of creatinine = 0.82 mg/dL. It is in the normal range.
Answer: The correct answer is "B" two bonding domains(or bonding pairs) or two non bonding domains(or lone pairs)
Explanation:
Molecular geometry/structure is a three dimensional shape of a molecule. It is basically an arrangement of atoms in a molecule.It is determined by the central atom, its surrounding atoms and electron pairs.According to VSEPR theory, there are 5 basic shapes of a molecule: linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral.
A)Four bonding domains and zero non bonding domains: shape is tetrahedral and bond angle is 109.5°
B)Two bonding domains and two non bonding domains(lone pairs): shape is bent and bond angle is 104.5°
C)Three bonding domains and one non bonding domain: shape is trigonal pyramidal and bond angle is 107°
D)Two bonding domain and zero non bonding domain: shape is linear and bond angle is 107°
E)Two bonding domain and one non bonding domain: bent shape and bond angle is 120°
F)Three bonding domains and zero nonbonding domain: shape is trigonal planar and bond angle is 120°
Hence Two bonding domains and two non bonding domains have the smallest bond angle.
Answer:
C) Conjugate Acid
Explanation:
H3O is the conjugate acid of H2O and X is the conjugate base of HX. The reaction going forward is the reaction of an acid and a base.
Answer:
B. 6m/s southeast
Explanation:
velocity= distance / time
= 180/ 30
6m/s southeast
One
molar mass NaCl
Na = 23
Cl =35.5
Molar mass = 58.6
mols = 450 / 58.5
mols = 7.69 mols
Concentration = mols / L
mols = 7.69
Volume = 4.5 kg = 4.5 L [1 liter weighs 1 kg]
C = 7.69 mol / 4.5 L
C = 1.71 mol/L
The question is unclear. I'm taking this to mean that you don't change the number of moles; you merely add 0.5 L to the volume.
Answer C = 7.69 / 5L = 1.54 mol / L
Two
I'm going to leave this. The wording just is not clear.
Three
More than you could grow in the entire planet earth for many centuries.
Ratio of sugar = 10 / (40 + 10 + 500) = 10 / 550 = 1:55 or 0.0182 to 1

Guava Juice = (36 / 100 ) * 100% = 36%
Water = (64/100 ) * 100 = 64%
