You were making a cream based sauce for your pasta and decided to add some freshly canned tomatoes to the sauce. It tasted fine,
soldier1979 [14.2K]

Answer & explanation:

Canned fruits and vegetables generally have a high acidity and salinity content, in order to prevent the product from spoiling, in addition to enhancing its flavor.

The cream-based sauce started to curdle due to the acidity present in the canned tomatoes.

By lowering the pH of dairy products, a protein in them called casein begins to clot. It is this clotting of the casein that causes the cream-based sauce to curdle.

Directions: Use the words in the word box to complete the following sentences.
NeX [460]

Explanation:

When the forces acting on an object are balanced , there is no change in the object's motion.

A force acting on a resting object can cause the object to move.

On Earth, gravity pulls all objects toward the ground.

When a force acts in the opposite direction of another force, the forces counteract each other.

More than one force acting on a falling object can reduce its downward acceleration

Air resistance is caused by molecules of air pushing against a moving object

A reasonable pka for a weak base is:<br><br> 10.3<br><br> 0.9<br><br> 5.8<br><br> 7.4<br><br> 13.1
andriy [413]

Answer:

0.9

Explanation:

The pka represents the force by which the molecules need to dissociate for the acids ,

Hence , lower the pka stronger will be the acid and that therefore will  dissociate completely and vice versa , for a weak acid higher the pka .

And in case of a base , it will be completely reversed , lower pKa , weaker base ,

and higher pKa , stronger base .

From the data of the question ,

0.9 is the lowest value of the pKa , hence , weakest base .
