Answer:

They attract each other

Explanation:

A magnet has two poles;

North pole and south pole

When two opposite poles are placed close to each other, they attract each other. The short rule is opposite opes attract.

When two like poles are placed close to each other, they repel each other. The short rule is like poles repel.

Answer:

1090 grams Sulfur (3 sig-figs)

Explanation:

Given 2.05 x 10²⁵ molecules CaSO₄ => 2.05 x 10²⁵ Sulfur atoms (subscript = 1 mole).

Converting 2.05 x 10²⁵ sulfur atoms to moles, divide by Avogadro's Number

(= 6.023 x 10²³ sulfur atoms / mole sulfur) => 2.05 x 10²⁵ sulfur atoms/6.023 x 10²³ sulfur atoms/mole sulfur atoms = 34.036 moles sulfur atoms.

Converting 34.036 moles sulfur to grams sulfur multiply by formula wt. of sulfur (=32g/mole S)

=> 34.036moles S x 32g/mole S = 1089.158 grams S ≅ 1090 g S (3 sig-figs)

Answer:

"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."

Explanation:

Answer:

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

Explanation:

Answer:

Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction is known as electrophilic addition.

Explanation:

Ethene will readily react with bromine, so the colour of the bromine water changes from red-brown to colourless. Bromine atoms will add across the double bond in ethene to produce just one product; 1,2-dibromoethane.

Complete Question:

Give one word for the following.

a. An undesirable constituent of air

b. The constituent of air that helps in burning

c. The thick layer of air surrounding the earth

d. Carbon dioxide does not support this process​

Answer:

a. Pollutant.

b. Oxygen.

c. Atmosphere.

d. Combustion.

Explanation:

a. Pollutant: an undesirable constituent of air. Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances known as pollutants. Some examples of pollutant are carbon monoxide, nitrogen dioxide, ozone, etc.

b. Oxygen: the constituent of air that helps in burning. Oxygen is an element that aids in the combustion (burning) process because it is an oxidizing agent.

c. Atmosphere: the thick layer of air surrounding the earth. It comprises of nitrogen, oxygen, carbon dioxide, argon and other gases in very small proportion.

d. Combustion (burning): Carbon dioxide does not support this process but it is an end product of the process.

Combustion can be defined as an exothermic chemical reaction between physical substances, usually in the presence of oxygen and hydrocarbons to produce heat, light and carbon.

Answer:

4.82 x 10^-4

Explanation:

7.23 x 10^-4 mol H2   l    2 mol NH3

------------------------------------------------------- =  

                                   l    3 mol H2

(7.23 x 10^-4) x 2   /  3 =

4.82 x 10^-4

Hope this helped! ;)

The mole of ammonia produced from 7.23 x 10⁻⁴ moles of the hydrogen reactant when there is sufficient nitrogen to react is 4.82×10⁻⁴.

Moles is a unit which is used to estimate the amount of any substance and it is represented as:
n = W/M , where

W = given mass

M = molar mass

Given chemical reaction is:
N₂(g) + 3H₂(g) → 2NH₃(g)

In the question it is given that sufficient moles of N₂ is present, so the formation of product depends on the moles of H₂. From the stoichiometry of the reaction, it is clear that:

3 moles of H₂ = produce 2 moles of NH₃

7.23×10⁻⁴ moles of H₂ = produce 2/3 × 7.23×10⁻⁴=4.82×10⁻⁴ moles of NH₃

Hence, option (C) is correct i.e. 4.82×10⁻⁴.

Answer:

5 Mg (magnesium), 2 N (nitrogen), and 6 O (oxygen) -- total of 13 atoms

There are 45 as 1 mg(NO3)2 = 9 atoms.

Explanation:

1. Find the empirical formula of a compound that has 36.84% of Nitrogen (N), 63.16% of Oxygen (O).

Secondly, Find molar mass of each component: N=14.0067, O=15.9994

Thirdly, convert to moles: N=2.6301698472874, O=3.9476480368014

Then find smallest mole value: 2.6301698472874

Divide all components my smallest value: N=1, O=1.5009099282591

Then divide by fractional component of each mole value: N=1.9963668986866, O=2.9963668986866

Round to closest whole numbers: N=2, O=3

Lastly, combine to get the empirical formula:N2O3

Answer:

500kg.

Explanation:

Newton's Second Law relates force, mass and acceleration to one another through the equation:

F = ma

We can rearrange this equation algebraically to solve for mass:

m = F/a

Substituting our known values for the variables, we get:

m = 1500N/3m/s2

So mass of the object is 500kg.

We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)

Answer:

The gas will occupy a volume of 1.702 liters.

Explanation:

Let suppose that the gas behaves ideally. The equation of state for ideal gas is:

[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)

Where:

[tex]P[/tex] - Pressure, measured in kilopascals.

[tex]V[/tex] - Volume, measured in liters.

[tex]n[/tex] - Molar quantity, measured in moles.

[tex]T[/tex] - Temperature, measured in Kelvin.

[tex]R_{u}[/tex] - Ideal gas constant, measured in kilopascal-liters per mole-Kelvin.

We can simplify the equation by constructing the following relationship:

[tex]\frac{P_{1}\cdot V_{1}}{T_{1}} = \frac{P_{2}\cdot V_{2}}{T_{2}}[/tex] (2)

Where:

[tex]P_{1}[/tex], [tex]P_{2}[/tex] - Initial and final pressure, measured in kilopascals.

[tex]V_{1}[/tex], [tex]V_{2}[/tex] - Initial and final volume, measured in liters.

[tex]T_{1}[/tex], [tex]T_{2}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]P_{1} = 121\,kPa[/tex], [tex]P_{2} = 202\,kPa[/tex], [tex]V_{1} = 2.7\,L[/tex], [tex]T_{1} = 288\,K[/tex] and [tex]T_{2} = 303\,K[/tex], the final volume of the gas is:

[tex]V_{2} = \left(\frac{T_{2}}{T_{1}} \right)\cdot \left(\frac{P_{1}}{P_{2}} \right)\cdot V_{1}[/tex]

[tex]V_{2} = 1.702\,L[/tex]

The gas will occupy a volume of 1.702 liters.

The elements found in the human body would be the following:

1. hydrogen,

2. oxygen,

3. carbon

4. nitrogen

They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA, and carbohydrates.

Answer:

1/4

Explanation:

Incomplete dominance is when the dominant ("R") gene is not completely dominant and cannot fully mask or cover the recessive ("r") gene. This means that it will result in both genes expressing and a mix of traits appearing. In the case of a flower with "R" genes for red and "r" genes for white, the following possibly combinations exist:

RR = all red, no white "r" gene

Rr = pink, as both the "R" and "r" genes are expressed

rr = white, no red "R" gene

The Punnett Square shows that only one of the four phenotypes is RR and red.

we know that the given mol is 8.23 mol and they are 2NaI and I2 so we will write the equation like this.

8.23mol NaI x 1mol of I2 ÷ 2molNaI = 4.115≅ 4.12 mol of I2

we placed NaI at the bottom to cancel out with the 8.23 mol of NaI
