schepotkina [342]

Imatinib is a small molecule kinase inhibitor. The BCR-ABL kinase can phosphorylate a series of downstream substrates, leading to proliferation of mature granulocytes. Bcr-Abl kinase substrate is the tyrosine. The Protein Tyrosine Kinase activity is an important requirement for malignant transformation, and that it cannot be complemented by any downstream effector, though not all interactions of BCR-ABL with other proteins are phosphotyrosine dependent.

The pH of a saturated solution of a metal hydroxide MOH is 10.15. Calculate the Ksp for this compound.
Airida [17]

Answer:

Ksp=2.00x10^{-8}

Explanation:

Hello!

In this case, since the pH of the given metal is 10.15, we can compute the pOH as shown below:

pOH=14-pH=14-10.15=3.85

Now, we compute the concentration of hydroxyl ions in solution:

[OH^-]=10^{-pOH}=10^{-3.95}=1.41x10^{-4}M

Now, since this hydroxide has the form MOH, we infer the concentration of OH- equals the concentration of M^+ at equilibrium, assuming the following ionization reaction:

MOH(s)\rightarrow M^+(aq)+OH^-(aq)

Whose equilibrium expression is:

Ksp=[M^+][OH^-]

Therefore, the Ksp for the saturated solution turns out:

Ksp=1.41x10^{-4}*1.41x10^{-4}\\\\Ksp=2.00x10^{-8}

Best regards!

A substance registers a temperature change from 20 to 40 to what incremental temperature change does this correspond
ss7ja [257]

<u>Given:</u>

Initial temperature, T1 = 20 C

Final temperature, T2 = 40 C

<u>To determine:</u>

The temperature change

<u>Explanation:</u>

Convert degree C to Kelvin

Temperature in Kelvin = degree C + 273

T1 = 20 + 273 = 293 K

T2 = 40 + 273 = 313 K

Incremental temperature change = T2 - T1 = 313-293 = 20 K

Ans: The temperature change in kelvin is 20 K
