Is The Following Nuclear Equation Balanced?NoYes

Answers

Answer 1

Answer:

Yes.

The nuclear equation {226/88 Ra → 222/26 Rn + 4/2 He} is balanced. As we know that an alpha particle is identical to a helium atom. This implies that if an alpha particle is eliminated from an atom's nucleus, an atomic number of 2 and a mass number of 4 is lost.

Therefore, the equation will be reduced to:

226 - 4 = 222

88 - 2 = 86

Hence, the equation is balanced.

Answers

The question is: WHAT DATA OF THE ELECTRONIC CONFIGURATION ALLOWS YOU TO LOCATE THE CHEMICAL ELEMENTS IN THE PERIODIC TABLE?

Explanation:

Elements which have same number of valence electrons tend to show similar chemical properties due to which they are placed in the same group.

Hence, electronic configuration of an element tells us the number of valence electrons present in an element. As a result, it becomes easy to locate the element in its respective group.

As the ZnCl2 dissolved, it separated into zinc ions and chloride ions. Choose the correct reaction.


A. Zinc was oxidized, chlorine was reduced.


B. Zinc was reduced, chlorine was oxidized.


C. This was not a redox reaction.

Answers

Answer:

This was not a redox reaction

Explanation:

A redox reaction is one in which a specie is oxidized and another specie is reduced. This means that one specie gains electrons while the other specie looses electrons.

Zinc chloride solid is composed of zinc ions and chloride ions. The ions only become free in solution. There is no change in the oxidation numbers of the ions as they dissolve in water.

Since the oxidation numbers of the species do not change, the process is not a redox reaction

A gas mixture contains 1.52 atm of Ne, 766 mmHg of He and Ar. What is the partial pressure, in atmospheres, of At if the gas mixture has a total pressure of 3.27atm

Answers

Answer:

0.74 atm.

Explanation:

From the question given above, the following data were obtained:

Pressure of Ne (Pₙₑ) = 1.52 atm

Pressure of He (Pₕₑ) = 766 mmHg

Total pressure (Pₜ) = 3.27 atm

Pressure of Ar (Pₐᵣ) =?

Next, we shall convert the pressure of He from mmHg to atm. This can be obtained as follow:

760 mmHg = 1 atm

Therefore,

766 mmHg = 766 mmHg × 1 atm / 760 mmHg

766 mmHg = 1.01 atm

Finally, we shall determine the partial pressure of Ar. This can be obtained as follow:

Pressure of Ne (Pₙₑ) = 1.52 atm

Pressure of He (Pₕₑ) = 1.01 atm

Total pressure (Pₜ) = 3.27 atm

Pressure of Ar (Pₐᵣ) =?

Pₜ = Pₙₑ + Pₕₑ + Pₐᵣ

3.27 = 1.52 + 1.01 + Pₐᵣ

3.27 = 2.53 + Pₐᵣ

Collect like terms

3.27 – 2.53 = Pₐᵣ

Pₐᵣ = 0.74 atm

Thus the partial pressure of Ar is 0.74 atm.

Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions?
Boyle’s law
Charles’s law
Dalton’s law
Gay-Lussac’s law

Answers

Answer:

Gay-Lussac’s law

Explanation:

Gay-Lussac’s law is one of the gas laws discovered and proposed by a French scientist called Joseph Gay Lussac (1778 - 1850). In this law, it is stated that the pressure (P) of a gas varies directly with the absolute temperature (T) at a constant volume.

That is;

: P ∝ T

: P/T = K

Where:

P = pressure exerted by the gas

T = absolute temperature of the gas

K = the constant.

Hence, according to this question, the law that states that "the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions" is Gay-Lussac’s law.

D. Move less

E. Become further apart

F. Become closer together

G. Overcome the attractive forces

H. The forces between them hold them more in place

Answers

Answer:

B, C, E, G

Explanation:

B - As particles are heated, they gain heat energy (or thermal energy, Q) from whatever the source may be.

C - Thermal energy particles gain is converted into kinetic, and the more KE/kinetic energy particles have, the more energy they have to move around.

E - When particles have more energy to move around more, they slide and move past each other and create more space; hence, they become further apart.

G - Eventually, particles will have enough energy and will move around so much that the attracting forces holding them together in the first place will be lesser than the particle's energy to break free and move from the attractive forces.

Given the following reaction:

If you start with 8.3 mL of 9.9M sulfuric acid, what is the theoretical yield of alum?

Answers

Answer:

19.4 g of alum, will be its theoretical yield

Explanation:

The reaction is:

2 Al + 2 KOH + 4 H₂SO₄ + 22H₂O → 3H₂ + 2KAl(SO₄)₂•12H₂O

Let's determine the amount of acid.

M are the moles contained in 1 L of solution or it can be mmoles that are contained in 1 mL of solution

M = mmol /mL

M . mL = mmol

We replace: 8.3 mL . 9.9 M = 82.17 mmoles

We convert to moles: 82.17 mmol . 1 mol / 1000mmol = 0.082 moles

Ratio is 4:2

4 moles of sulfuric acid can make 2 moles of alum

By the way, 0.082 moles of acid may produce ( 0.082 . 2) /4 = 0.041085 moles.

We convert moles to mass:

Molar mass of alum is: 473.52 g/mol.

0.041085 moles . 473.52 g/mol = 19.4 g

1.1 Define the concept risky behaviour?​

Answers

Answer:

Risky behavior or risk-taking behavior is defined according to Trimpop (1994) as “any consciously, or non-consciously controlled behavior with a perceived uncertainty about its outcome, and/or about its possible benefits, or costs for the physical, economic or psycho-social well-being of oneself or others.” In addition to this broad definition, there are other definitions of risky behavior depending on the field of research. While in the economic view, risk is defined in terms of the variability of possible monetary outcomes, in the clinical literature, the risk is generally defined as exposure to possible loss or harm (Schonberg, Fox, & Poldrack, 2011). Turner et al. (2004) described risk-taking behavior further as either a socially unacceptable volitional behavior with a potentially negative outcome in which precautions are not taken, such as speeding, drinking and driving, drugs abuse, unprotected sex and so on.

What volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution?​

Answers

So you add 1.4 L of 12M NaOH to 0.6 L of 2M NaOH to get 2 L of 9M NaOH.

The volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution is 1.4 L and 0.6 L

What is Concentration ?

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture.

Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

Amount of stuff = concentration x volume.

We can set up 2 equations:

V₁ = volume 12M NaOH.V₂ =  volume 2M NaOH.

(12×V₁) + (2×V₂) = 9×2 = 18

12V₁ + 2V₂ = 18 (1)

V₁ + V₂ = 2 (2)

From (2) we get:

V₁ = (2 − V₂)

Substituting  V₁ back into (1)  ⇒

12 (2−V₂) + 2V₂ = 18

24 − 12V₂ + 2V₂ = 18

10V₂ = 6

V₂ = 0.6L

From (2) we can say:

V₁ + 0.6 = 2

V₁ = 2 − 0.6 = 1.4L

Therefore, The volume of 12 M NaOH and 2 M NaOH should be mixed to get 2 litres of 9 M NaOH solution is 1.4 L and 0.6 L
