Answer:

The Food Chain: The answer has to do with trophic levels. As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.

The correct response is "9.313 M".

Explanation:

According to the question, the values are:

Moles of solute,

= 0.57 moles

Liters of solution,

=  61.2 mL

or,

= 0.0612 L

Now,

The molarity will be:

= [tex]\frac{Moles \ of \ solute}{Liters \ of \ solution}[/tex]

On putting the given the values in the above formula, we get

= [tex]\frac{0.57}{0.0612}[/tex]

= [tex]9.313 \ M[/tex]

Answer:

The stable ion the sulfur would form is the sulfide ion,

Explanation:

When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.

Sulfur is an elemental atom that has an atomic number of 16 and an atomic mass of 32.065 amu. If the sulfur atom gains three protons then potassium will be formed.

A proton has been a sub-atomic particle that has been known to carry a positive charge and are tend to remain inside the nucleus with the neutrons bonded together by the nuclear force.

The proton of the atom is the characteristic property of the element in the periodic table. They are the sole sub-atomic particle that gives the atomic number of the elemental atom.

The sulfur atom has the atomic number 16 which means it has 16 protons, so if three protons are added to it then the number f protons become 19 which is an atomic number of the potassium (K) element.

Therefore, a potassium element is formed.

Answer:

A)Trial 1 because the average rate of reaction is lower.

Explanation:

I accidentally gave myself low rating my bad

The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.

When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases

Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Answer:

74.99g

Explanation:

Mass of a substance can be calculated by using the formula;

mole = mass ÷ molar mass

mass = molar mass × mole

According to this question, 37.2 moles of hydrogen gas is given.

Molar mass of hydrogen gas (H2) = 1.008(2) = 2.016g/mol

mass = 2.016 × 37.2

Mass of H2 = 74.995

Mass = 74.99g

Answer:

101.62 grams of water is given o when 62.1 g of propane burns.

Explanation:

Propane gas (C₃H₈) burns with oxygen gas and products carbon dioxide gas and liquid water. The balanced reaction is:

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

By stoichiometry, the following amounts of moles of each compound participate in the reaction:

Being the molar mass of each compound:

By stoichiometry, the following mass quantities of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 44 grams of propane produces 72 grams of water, 62.1 grams of propane how much mass of water does it produce?

[tex]mass of water=\frac{62.1 grams of propane*72 grams of water}{44 grams of propane}[/tex]

mass of water= 101.62 grams

101.62 grams of water is given o when 62.1 g of propane burns.

Answer:

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Explanation:

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to Q = m*L, where L is called the latent heat of the substance and depends on the type of phase change.

During the evaporation process, a substance goes from a liquid to a gaseous state and needs to absorb a certain amount of heat from its immediate surroundings, which results in its cooling. The heat absorbed is called the heat of vaporization.

So, it is called "heat of vaporization", the energy required to change 1 gram of substance from a liquid state to a gaseous state at the boiling point.

In this case, being:

and replacing in the expression Q = m*L you get:

Q=172 g*84 [tex]\frac{J}{g}[/tex]

Q=14,448 J

14,448 J of heat would it take to completely vaporize 172 g of this liquid at its boiling point.

Answer:

116.88 g

Explanation:

Step 1: Write the balanced equation for the synthesis of NaCl

Na + 1/2 Cl₂ ⇒ NaCl

Step 2: Calculate the moles corresponding to 45.978 g of Na

The molar mass of Na is 22.990 g/mol.

45.978 g × 1 mol/22.990 g = 1.9999 mol

Step 3: Calculate the number of moles of NaCl formed from 1.9999 moles of Na

The molar ratio of Na to NaCl is 1:1. The moles of NaCl formed are 1/1 × 1.9999 mol  = 1.9999 mol.

Step 4: Calculate the mass corresponding to 1.9999 moles of NaCl

The molar mass of NaCl is 58.443 g/mol.

1.9999 mol × 58.443 g/mol = 116.88 g

Answer:

1. It is stoichiometric.

2. O2 is the limiting reactant.

3. 9.0 g of C2H6 remain unreacted.

4. 17.6 g of CO2.

5. 85.2%.

Explanation:

Hello there!

In this case, for the given chemical reaction:

[tex]2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O[/tex]

We can see that:

1. It is stoichiometric and is balanced because the reactants yields the products according to the law of conservation of mass.

2. In this part, it is possible to calculate the moles of ethane by using its molar mass:

[tex]n_{C_2H_6}=15g*\frac{1molC_2H_6}{30.08g} =0.50molC_2H_6[/tex]

And the moles of oxygen by knowing that one mole is contained in 22.4 L at STP:

[tex]n_{O_2}=\frac{1mol}{22.4L} *15.68L=0.7molO_2[/tex]

Thus, by calculating the moles of carbon dioxide product by each reactant, we can identify the limiting one:

[tex]n_{CO_2}^{by\ C_2H_6}=0.50molC_2H_6*\frac{4molCO_2}{2molC_2H_6} =1.0molCO_2\\\\n_{CO_2}^{by\ O_2}=0.70molO_2*\frac{4molCO_2}{7molO_2} =0.4molCO_2\\[/tex]

Thus, since oxygen yields the fewest moles of CO2 product, we infer it is the limiting reactant.

3. In this part, we calculate the mass of C2H6 that actually react first:

[tex]m_{C_2H_6}^{reacted}=0.4molCO_2*\frac{2molC_2H_6}{4molCO_2}*\frac{30.08gC_2H_6}{1molC_2H_6} =6.0gC_2H_6[/tex]

Thus, the leftover of ethane (C2H6) as the excess reactant is:

[tex]m_{C_2H_6 }^{leftover}=15g-6.0g=9.0g6.0C_2H_6[/tex]

4. Since 0.4 moles of carbon dioxide were produced, we use its molar mass to calculate the mass as its theoretical yield:

[tex]m_{O_2}^{theoretical}=0.4molCO_2*\frac{44gCO_2}{1molCO_2}=17.6gCO_2[/tex]

5. Finally, the percent yield is gotten by dividing the actual yield by the theoretical one:

[tex]Y=\frac{15g}{17.6}*100\%\\\\Y=85.2\%[/tex]

A cubic centimeter of water weighs 1 gram. Since a cubic centimeter of vegetable oil weighs less than 1 gram, oil will float on water. Corn syrup is more dense than water so 1 cubic centimeter of corn syrup weighs more than 1 gram. Therefore, corn syrup sinks in water.

Answer:

1.5 m/s²

Explanation:

From the diagram,

F-F' = ma............... Equation 1

Where F = Forward force of the vehicle, F' = Frictional force, m = mass of the electric car, a = acceleration of the car.

make a the subject of the equation

a = (F-F')/m........... Equation2

Given: F = 3500 N, F' = 500 N, m = 2000 kg

Substitute into equation 2

a = (3500-500)/2000

a = 3000/2000

a = 1.5 m/s²
