Explanation:

Answer:

friction

Explanation:

The other terms honestly just don't make any sense in this context. Round objects experience less friction, since they have less of their surface touching the ground at a time. Imagine a bowling bowl: only a small part of the ball is ever touching the ground at one instant. Now imagine a waffle: almost all of the surface is touching the ground.

.Answer:

2kclo3 --> 2kcl + 3o2 is a decomposition reaction because it is breaking apart (thinks decompose- to break apart/down)

H2 + I2 --> 2HI is a synthesis reaction because synthesis is like creation/ building

think DNA synthesis or the book of genesis in the bible about creation

2 Na + 2 H20 --> NaOH + H2 --- not balanced at all

other one is a balanced equation- the Zn + 2HCl one

Explanation:

Answer:

A. The reaction proceeds in the forward and reverse directions at the same rate.

B. Both the forward and the reverse reactions are achievable.

D. There is no net change in concentrations of reactants and products.

Explanation:

Chemical equilibrium can be defined as the state of a reversible reaction in which the concentration (rate) of the forward reaction is equal to the concentration (rate) of the backward or reverse reaction. Thus, both the reactants and products of the chemical equation don't have the tendency to change with respect to time.

Hence, the options that are true of chemical equilibria include the following;

I. The reaction moves in both forward and reverse directions simultaneously i.e at the same rate.

II. The chemical equation can attain both forward and reverse reactions.

III. The concentrations of both reactants and products are the same i.e there's no net change.

Explanation:

Answer:

1.1 × 10² g

Explanation:

Step 1: Given data

Step 2: Calculate the moles of Mg(NO₃)₂ (solute)

Molarity is equal to the moles of solute (n) divided by the liters of solution.

C = n/V

n = C × V

n = 0.50 mol/L × 1.500 L = 0.75 mol

Step 3: Calculate the mass corresponding to 0.75 moles of Mg(NO₃)₂

The molar mass of Mg(NO₃)₂ is 148.3 g/mol.

0.75 mol × 148.3 g/mol = 1.1 × 10² g

Answer:

One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo E1 or E2 mechanisms to lose water and form a double bond. The dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high tempera (sorry if this is wrong )

Kc = [H3O+][HCO3-] / [H2CO3]

Remember that Kc is products over reactants. Also, you do not include liquid water in a Kc expression, since liquid water has no concentration.

Answer:C and D

Explanation:Just did it

Increasing the pressure and Decreasing the temperature are the two changes would make this reaction product-favored.

It is a state when a reaction is reversible and both forward and reverse reaction occur simultaneously at the same rate .

In the process of manufacture of Ammonia , both forward and reverse reaction are taking place

N₂(g) + 3H₂ (g) →  2NH₃ (g)

2NH₃(g)  →  N₂ (g) + 3H₂ (g)

when these reaction occur at same rate , the state is called equilibrium and is represented by

N₂ (g) + 3H₂(g) ⇔ 2NH₃(g) +Heat

As we can see from the equation , heat is produced in the forward reaction so if we increase the temperature the reverse reaction will be favored ,

On decreasing temperature the reaction will become product favored .

While on increasing the Pressure the manufacture of Ammonia increases.

Therefore Option C and Option D are the two changes would make this reaction product-favored.

Answer:

Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body.

Explanation:

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Answer:

A reduction potential measures the tendency of a molecule to be reduced by taking up new electrons. ... Standard reduction potentials can be useful in determining the directionality of a reaction. The reduction potential of a given species can be considered to be the negative of the oxidation potential.

Answer:

In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material.

The symbols for three different cations with 14 protons are Si²⁺, Si⁴⁺, and Si³⁺. An element with 14 protons must be silicon, Si. Its electron configuration is [Ne] 3s²3p², so it could lose up to four valence electrons. The most likely cations are Si²⁺, Si⁴⁺, and Si³⁺ (or Si⁺)

In this case, since the second-order integrated law is given by the following equation:

[tex]\frac{1}{[H_2O_2]} =\frac{1}{[H_2O_2]_0}+kt[/tex]

Thus, given the initial and final concentration of hydrogen peroxide and the rate constant, we obtain the following time:

[tex]\frac{1}{[0.0170M]}-\frac{1}{0.0800M}=0.650M^{-1}s^{-1}t\\\\t=\frac{46.32M^{-1}}{0.650M^{-1}s^{-1}} \\\\t=71.3s[/tex]

Answer:

3.27*(10^-5) M

Explanation:

For 25°C:

[H3O+] *[OH-] =(10^-14)-->

[OH-]=(10^-14)/[H3O+]-->

[OH-]=(10^-14)/(3.06*10^-10)-->

[OH-]=3.27*(10^-5) M

Answer:

8.44 atm

Explanation:

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

Initial volume (V₁) = 2.25 L

Initial temperature (T₁) = 350 K

Initial pressure (P₁) = 1.75 atm

Final volume (V₂) = 1 L

Final temperature (T₂) = 750 K

Final pressure (P₂) =?

The final pressure of the gas can be obtained as illustrated below:

P₁V₁/T₁ = P₂V₂/T₂

1.75 × 2.25 / 350 = P₂ × 1 / 750

3.9375 / 350 = P₂ / 750

Cross multiply

350 × P₂ = 3.9375 × 750

350 × P₂ = 2953.125

Divide both side by 350

P₂ = 2953.125 / 350

P₂ = 8.44 atm

Thus, the final pressure of the gas is 8.44 atm.

Explanation:

Hello there!

In this case, for these types of acid-base neutralizations, it is crucial to firstly set up the chemical reaction taking place between the acid and the base; in this case HCl and Mg(OH)2 respectively, whose products are obtained by switching around the anions and cations as shown below:

[tex]HCl(aq)+Mg(OH)_2(aq)\rightarrow MgCl_2(aq)+H_2O(l)[/tex]

Which must be balanced to accurately predict the mole ratio on the reactants side:

[tex]2HCl(aq)+Mg(OH)_2(aq)\rightarrow MgCl_2(aq)+2H_2O(l)[/tex]

Whereas we can see a 2:1 mole ratio of the acid to the base; thus, the moles of Mg(OH) required for the neutralization of 6.0 moles of HCl turn out to be:

[tex]6.0molHCl*\frac{1molMg(OH)_2}{2molHCl} \\\\=3.0molMg(OH)_2[/tex]

Answer: Yes

Explanation: Because the color changed and one of the ways to see if a chemical reaction occured is color change.

First, make sure to balance your equation.

3H2(g) + N2(g) ⇄ 2NH3(g)

Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.

Kc = [NH3]^2 / [H2]^3[N2]

The reaction between nitrogen and hydrogen is called the Haber process. Kc for the reaction is the ratio of the concentration of ammonia to nitrogen and hydrogen.

An equilibrium constant, kc is the concentration proportion of the products to the concentration of the reactants raised by their respective coefficients.

The balanced chemical Haber process is given as:

[tex]\rm 3H_{2}(g) + N_{2}(g) \leftrightharpoons 2NH_{3}(g)[/tex]

Now, the equilibrium constant for the reaction can be given as:

[tex]\rm Kc = \rm \dfrac{[NH_{3}]^{2}}{[H_{2}]^{3}[N_{2}]}[/tex]

Therefore, the ratio of the concentration of ammonia to hydrogen and nitrogen gives the equilibrium constant.
