compare the activity of sodium and iron with water and dilute acid​

Answers

Answer:

Reactions of sodium with water and dilute acid

Sodium reacts explosively with dilute HCl(aq) to produce NaCl(aq) and H₂(g)

2Na (s) + 2HCl(aq) → 2NaCl(aq) + H₂(g)

Sodium reacts violently with cold water to produce NaOH(aq) and H₂(g)

2Na (s) + H₂O(l)  → 2Na(OH)(aq) + H₂(g)

The produced hydrogen may become ignited and explode

Reactions of iron with water and dilute acid

Iron reacts very slowly with dilute acid to produce iron (II) chloride and hydrogen gas

Fe (s) + 2 HCl (aq) →  FeCl₂ (aq) + H₂ (g)

Iron does not react with cold water. Iron reacts only with steam

Answers

Answer:

occur if two of the ions form an insoluble ionic compound, which precipitates out of solution

Explanation:

When two ionic compounds are dissolved in water, a double replacement reaction takes place if two of the ions form an insoluble ionic compound, which precipitates out of solution. In double displacement reaction ions switch partners. And hence, produce an insoluble precipitate.

PLZ HELP! TIMED TEST Which of the following groups of elements are likely to have elements in the three states of matter? (1 point)
Alkali metals
Actinides
Halogens
Lanthanides

Answers

Answer:

Halogens

Explanation:

Matter is defined as a substance which has mass and occupies volume. The three states of matter are solid, liquid and gas.

Elements which are present in group 17 are known as halogens.

Elements present in this group are fluorine, chlorine, bromine and iodine.

At room temperature, both fluorine and chlorine exists as a gas.

Bromine exists as a liquid and iodine exists as a solid.

Therefore, we can conclude that halogen groups are likely to have elements in three states of matter.

When an object falls toward the ground due to gravity, what type of energy becomes kinetic energy?

Answers

Answer:

potential energy (gravitational)

Explanation:

Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. If we think of the ground as the zero height, the height of the object is coming down from a positive height.  Wherever it is relative to the zero height, it is stored at that height, meaning that it is potential energy at that particular height.  When it moves to the ground, it becomes kinetic, by gravitational means.

The pH of a solution decreases by 2.0. How does the hydronium ion concentration of the solution change? Increases to 2 times the original concentration increases to 100 times the original concentration decreases to one one hundredth. Of the original concentration decreases to one half. Of the original concentration

Answers

Answer:

The hydronium ion concentration increases to 100 times the original concentration

Explanation:

The pH of a solution is defined as the negative logarithm of the hydrogen or hydronium ion concentration of that solution. It is given by the expression below:

pH = -log[H₃O⁺] = log[H₃O⁺]⁻¹

Assuming the solution was at neutral with original pH = 7;

The new pH of the solution will be = 7 - 2 = 5

At pH = 7;

log[H₃O⁺]⁻¹ = 7

[H₃O⁺]⁻¹ = 10⁷

[H₃O⁺] = 10⁻⁷

At pH = 5

log[H₃O⁺]⁻¹ = 5

[H₃O⁺]⁻¹ = 10⁵

[H₃O⁺] = 10⁻⁵

10⁻⁵ = 10⁻⁷ * 10²

But 10² = 100

Therefore, the hydronium ion concentration increases to 100 times the original concentration

calculate the weight of 3.491 into 10 to the power 19 molecules of cl2​

Answers

Answer:

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ is 4.11 × 10⁻³ grams

Explanation:

The number of particles in one mole of a substance id=s given by the Avogadro's number which is approximately 6.023 × 10²³ particles

Therefore, we have;

One mole of Cl₂ gas, which is a compound, contains 6.023 × 10²³ individual molecules of Cl₂

3.491 × 10¹⁹ molecules of Cl₂ is equivalent to (3.491 × 10¹⁹)/(6.023 × 10²³) = 5.796 × 10⁻⁵ moles of Cl₂

The mass of one mole of Cl₂ = 70.906 g/mol

The mass of 5.796 × 10⁻⁵ moles of Cl₂ = 70.906 × 5.796 × 10^(-5) = 4.11 × 10⁻³ grams

Therefore;

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ = 4.11 × 10⁻³ grams.

Extrusion is the feature form at Earth's surface from the cooling of lava.

What are extrusive igneous rocks?

They are the ones that originate from a sudden cooling of the incandescent magma when it comes to the surface, which means that there is no time for crystals to form, either partially or totally.

Characteristics of extrusive igneous rocks

These are rocks formed mainly by silicate minerals.

Pyroclastics are the product of explosive volcanic eruptions and contain rock fragments of different origins, they can be of many shapes and sizes.

Cultural absolutism is the term for the belief that one's own culture is superior to other cultures.

What is cultural absolutism?

Cultural absolutism is one of the perspectives which is common in anthropology, but it can  also be applied to non-scientific thoughts also. It assumes that there is a set of universal values which are objectively valid in every  situation.

Today, pure cultural absolutism is seen as a harmful effect of ethnocentrism focusing on  the belief that one's own culture is superior and the practice of holding other's cultures to the standard of our own. However, purely relativist anthropologists have also been critiqued for going too far, by  denying any common humanity and being too lenient towards morally questionable practices. Contemporary approaches try to find a balance between  the universal values, such as human dignity, and a more inclusive and relativistic side  of culture.

Answers

Answer:

Explanation:

If we are to add 9.7300x10^2 + 9.8700x10^3, we must first make the powers of the both to be be the same so that we can carry out any mathematical manipulation of interest. So we can have;

9.7300x10^2 + 98.700x10^2

When we now add the both we have (9.7300 + 98.700)×10^2.

This now gives us the result, 108.43×10^2 which is correctly written as 1.0843×10^4, according to the rules of writing in scientific notation.

why there are two chloride ions for every calcium ion

Answers

Answer:

The valency of calcium is +2

Explanation:

Calcium is in group two. The members of group two are divalent metals that loose two electrons to form M^2+.

Since they form M^2+, they form ionic bonds with two uninegative ions. Chlorine is in group 17. This implies that its valency is -1 and it accepts one electron when it participates in an ionic bond.

Hence it will take two chlorine atoms to receive two electrons from one calcium atom in an ionic bond making the ratio of calcium to chlorine in the compound 2:1.

Answers

Answer:

603000 J

Explanation:

The following data were obtained from the question:

Energy required (Q) =...?

Mass (M) = 10000 g

Specific heat capacity (C) = 2.01 J/g°C

Overheating temperature (T2) = 121°C

Working temperature (T1) = 91°C

Change in temperature (ΔT) =.?

Change in temperature (ΔT) =T2 – T1

Change in temperature (ΔT) = 121 – 91

Change in temperature (ΔT) = 30°C

Finally, we shall determine the energe required to overheat the car as follow:

Q = MCΔT

Q = 10000 × 2.01 × 30

Q = 603000 J

Therefore, 603000 J of energy is required to overheat the car.
