What is a dry climate?

The areas which are very dry and where the water escapes and leaves the area drier than other places is known as the dry climate. Most dry climates have summers very hot, winters cool and warm and the air is very dry.

The main characteristic feature of the dry climate is the low and infrequent rainfall. Arid and semi desert areas have only about 35 cm rainfall per year.

Answers

Answer:

The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products

Explanation:

How many atoms of the element with atomic number 11 are in the reactants of the given formula?

2 NaCl + H2SO4 → 2 HCl + Na2SO4

Answers

The number of Na atoms in the reactants = 2

Further explanation

Every chemical reaction involves compounds that can act as reactants or products

The reactants will react to produce products

The reactants are usually written on the left side of the reaction, while the products on the right side of the reaction

Reaction

2 NaCl + H₂SO₄ → 2 HCl + Na₂SO₄

The element with atomic number 11  = Na(Natrium)

The number of atoms of the element that reacts or is produced can be seen from the reaction coefficient and the number of atoms in the compound

Na in NaCl = 1 atom

From equation, cofficient for NaCl = 2, so number of atoms of Na=2 x 1 = 2

If you leave your home at noon, and the speed limit is 50 km/h on the highway, what is the approximate time will you get to Atlantic City if Atlantic City is 150 km away? (obeying the speed limit of course)

Answers

Answer:

The time you will get to Atlantic City is 3 pm

Explanation:

Given;

speed limit, v = 50 km/h

distance to be traveled, d = 150km

The time of the motion is given as;

time = distance / speed

t = (150 km) / (50 km/h)

t = 3 hours

Thus, if you leave your home at noon, the time you will get to Atlantic City is given as;

time to get home = 12 pm + 3hours = 3 pm

Therefore, the time you will get to Atlantic City is 3 pm

The object which is most likely to be damaged by an acid is Choice D: An aluminium can.

When an acid undergoes ionization in an aqueous solution, the positively charged ion released is; Hydroxonium ion, H30+.

In essence, the hydrogen ion of an acid can be displaced by the Aluminium ion in the aluminium can.

This phenomenon is evident in the arrangement of metals in the electrochemical series.

Aluminium is more reactive than the hydrogen ion. As such, an Aluminium can is most likely to be damaged by an acid.

EXPLAIN What is one way that the thermal energy of a system can be changed?

Answers

Answer:

When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.

Explanation:

BTW I GOT THE ANSWER FROM KRISTINA

The thermal energy of a system is the amount of heat energy in it.

One way to change thermal energy is by alter the system by introducing a new object to the system.

The thermal energy of a system is calculated using:

[tex]E = \frac 12 mc\theta[/tex]

Assume the mass of the system remains unchanged.

When an object is introduced to the system, the thermal energy becomes:

[tex]E_2 = \frac 12 mc(\theta + \alpha)[/tex]

Where:

[tex]\alpha \ne 0[/tex] --- the temperature of the object.

Expand:

[tex]E_2 = \frac 12 mc(\theta) + \frac 12 mc (\alpha)[/tex]

Substitute: [tex]E = \frac 12 mc\theta[/tex]

[tex]E_2 = E + \frac 12 mc (\alpha)[/tex]

This means that the thermal energy of the system will change by the thermal energy of the object that is being introduced to the system.

Hence, one way the thermal energy can be changed is to introduce a new object (or matter).

When atoms form ions, they usually loose or gain enough electrons to achieve the electronic configuration of a noble gas. Metal atoms loose electrons while nonmetal atoms gain electrons.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Which two reactions are slower than the others?
A. Silver tarnishes in air that contains hydrogen sulfide.
B. Lead nitrate and potassium iodide react to form a yellow
precipitate.
C. Black powder in fireworks burns explosively to produce white
light
D. Iron metal reacts with oxygen in air to form rust.

Answers

Answer:

A and D takes much slower

Explanation:

Here, we want to select, out of the four given reactions, the one that is slower than the other two

The answers in these case are reactions 1 and 4 ( A and D)

The two reactions show what is called rust (as directly seen in reaction 4)

When we speak of rust, we simply mean a reaction that occurs over time

For example, non coated roofings of houses doesn’t get to change color at an instant

The color degradation that occurs is something that takes some time from the initial time they were used to roof the house

Hence, from these analogy, we can see that these reactions need an an external support to thrive or to come into existence

These external supports are natural forces and they contributing efforts occur over time and cannot be seen immediately

These reactions are thus ones that take much slower time than conventional laboratory reactions in the case of the formation of the precipitate or a reaction that requires a low flash point temperature such as that of black powder to produce such explosive effects

So in conclusion, what we are saying is that the two selected reactions are subjected to the availability of some conditions and may take time to manifest and these absolutely differentiates them from reactions that are spontaneous such as the one having an explosive effect or the other one leading to the formation of a precipitate which takes far less times
