Answer:
C
Explanation
Because My teacher told me that for an example Florida is hot but in Central America is cold or hot and you don’t need a jacket. I don’t remember much
Answer:
Temperature at which molybdenum becomes superconducting is-272.25°C
Explanation:
Conductor are those hard substances which allows path of electric current through them. And super conductors are those hard substances which have resistance against the flow of electric current through them.
As given, molybdenum becomes superconducting at temperatures below 0.90 K.
Temperature in Kelvins can be converted in °C by relation:
T(°C)=273.15-T(K)
Molybdenum becomes superconducting in degrees Celsius.
T(°C)=273.15-0.90= -272.25 °C
Temperature at which molybdenum becomes superconducting is -272.25 °C
Answer: 65.7 grams
Explanation:
1) ratio
Since 1 mole of CaF2 contains 1 mol of F2, the ratio is:
1 mol CaF2 : 1 mol F2
2) So, to produce 8.41 * 10^ -1` mol of F2 you need the same number of moles of CaF2.
3) use the formula:
mass in grams = molar mass * number of moles
molar mass of CaF2 = 40.1 g/mol + 2 * 19.0 g/mol = 78.1 g/mol
mass in grams = 78.1 g/mol * 8.41 * 10^ -1 mol = 65.7 grams
Answer:
B) hyperbolic curve; saturated with substrate
Explanation:
Enzymatic kinetics studies the speed of enzyme catalyzed reactions. These studies provide direct information about the mechanism of the catalytic reaction and the specificity of the enzyme. The speed of a reaction catalyzed by an enzyme can be measured with relative ease, since in many cases it is not necessary to purify or isolate the enzyme. The measurement is always carried out under the optimal conditions of pH, temperature, presence of cofactors, etc., and saturating substrate concentrations are used. Under these conditions, the reaction rate observed is the maximum speed (Vmax). The speed can be determined either by measuring the appearance of the products or the disappearance of the reagents.
Following the rate of appearance of product (or disappearance of the substrate) as a function of time, the so-called reaction progress curve is obtained, or simply, the reaction kinetics. This curve is represented by a hyperbolic curve
Answer:
=37.83783784
Explanation:
Find the total sum of all coins,
which is 37, take the number of pennies and the total of all coins put in parenthesis( 14/37) like so and than * times them by 100
you equation should look like this
(14/37)* 100= and than the answer shown above should be the one you received. I have checked this with multiple calculators, it should be accurate.
