.A pH meter is divided into two. The numbers that are lesser than 7 are the pH numbers of acids. The lesser the number, the stronger is the acid. Further, the numbers greater than 7 are for the bases and the stronger the base, the higher is the value for the pH. Thus, the answer to this item is the fourth choice, strong base.

Why do elements in the same group have a similar reactivity?
katrin2010 [14]
Elements in the same group have the same number of outer-shell electrons or "valence" electrons, so they tend to react similarly, as they can form similar bonds.

How many moles of calcium are there in 5.74 x 1022 atoms of calcium?
igor_vitrenko [27]

Answer:

0.095 moles of Calcium is there in 5.74 x 1022 atoms of calcium.

Explanation:

  • As we know, 6.023*10^23 atoms of an element is equal to its atomic weight.

       And, 6.023*10^23 atoms of an element is also equal to 1 mole of the             element.

We have,

  • 6.023*10^23 atoms of element calcium equals to 1 mole of Calcium
  • 5.74*10^22 atoms of element calcium equals to

         (1/(6.023*10^.23)) * 5.74*10^22 moles of calcium

Therefore,

  • 5.74 x 1022 atoms of calcium= 0.095 moles of calcium.

The picture shows two containers filled with a gas.
Irina18 [472]

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

<h3>What is temperature?</h3>

The term temperature refers to a measure of the average kinetic energy of the molecules of  body. This means that molecules that are at high temperature tend to move faster than the molecules that are at low temperature.

As such, the higher temperature of the molecules of the gas in B shows that the molecules in B are faster than those in A thus the correct statement is; "the average kinetic energy of the gas particles is greater in container B because it has a higher temperature."

#SPJ1

Missing parts;

The picture shows two containers filled with a gas.

Two equally sized containers are shown with tight lids and each container has a thermometer. The container on the le is labeled A and the one on the right is labeled B. The thermometer inside container B shows a higher temperature than the thermometer inside container A.

Which statement is correct?

The average kinetic energy of the gas particles is greater in container A because it has a lower temperature.

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

The gas particles in both containers have the same average kinetic energy because t have the same volume.

The gas particles in both containers have the same average kinetic energy because t have equal number of particles.

Pls i need help with this
gregori [183]

Answer:

C

Explanation:

A physical change is one in which no new substance is formed. The moistening of food by saliva is purely a physical change because no new substance is formed in the process.

A chemical change leads to the formation of a new substance. The action of the enzyme converts starch into sugar which means that a new substance is formed. This is a chemical change.
