Answer:

1.66x10⁶kJ of energy are produced

Explanation:

...Produces 45kJ... Has a density of 0.77g/mL... By burning 48L of gasoline...

To solve this question we need to calculate the mass in grams of gasoline in 48L using its density.

With the mass and knowing 1gram produces 45kJ of energy we can find the energy produced by burning 48L of gasoline, thus:

mL of gasoline:

48L * (1000mL / 1L) = 48000mL of gasoline

g of gasoline:

48000mL * (0.77g/mL) = 36960g of gasoline

Energy produced:

36960g of gasoline * (45kJ / g) =

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{7 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{7}{6.02} \\ = 1.162790....[/tex]

We have the final answer as

Answer:  Protons

Explanation:

Answer:

Oxygen

Explanation:

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

Number of electrons = 8

Number of protons = 8

Number of Neutrons = 8

Name of element =?

Next, we shall determine the atomic number of the element. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons in the atom of the element. Mathematically, it is expressed as:

Atomic number = proton number

From the question given above,

Number of protons = 8

Therefore,

Atomic number = 8

Comparing the atomic number of the element (i.e 8) with those in the periodic table, we can conclude that the element is oxygen since no two elements have the same atomic number.

Answer:

4.46 °C

Explanation:

Step 1: Given and required data

Step 2: Calculate the temperature change

We will use the following expression.

Q = c × m × ΔT

ΔT = Q / c × m

ΔT = 4430 J / (4.186 J/g.°C) × 237 g

ΔT = 4.46 °C

The temperature change is 4.46 °C.

Seismic waves can move through both empty space and matter. Electromagnetic waves differ from sound waves in this regard because they do not require molecules to move.

Answer:

Ethanol.

Explanation:

Hello!

In this case, since the Fischer esterification stand for the organic acid-base reactions, we infer that the alcohol is related to the -yl part on the name (ethyl propanoate) as the alcohol is likely to lose the -OH and provide a carbocation for the carboxyl group of the carboxylic acid.

In such a way, since the -yl part is given as ethyl, we infer the used alcohol is ethanol:

Answer:

102.4 g

Explanation:

The equation of the reaction is;

2SO2(g) + O2(g) -----> 2SO3(g) --------ΔH = -198 KJ/mol

Now, given that;

If 2 moles of SO2 evolves 198 KJ/mol of heat

x moles of SO2 evolves 163 KJ/mol of heat

x = 2 * 163/198

x = 1.6 moles of SO2

molar mass of SO2 = 64 g/mol

mass of SO2 = 1.6 moles * 64 g/mol = 102.4 g

Explanation:

The volume of avocado here is 250 ml as per the given data i.e., mass of 215 g and a density of 0.86 g/mL.

The density of an artifact is delineated as its mass divided by the volume. Density is commonly expressed in grams per cubic centimeter.

The grams are a unit of mass and indeed cubic centimeters are a unit of volume. A box with more particles will be denser than a box with fewer particles.

The density of a solid, liquid, or gas illustrates how closely packed the particles can be. The amount of mass per unit volume is defined as density.

Density is defined as d = M/V, where d is density, M is mass, and V is volume. Density is commonly measured in grams per cubic centimetre.

We know that,

Density = mass/volume.

Volume = mass/density.

Here, it is given that

Density = 0.86 g/mL.

Mass = 215 g.

Volume = 215/0.86 mL.

Volume = 250 mL.

Thus, the answer is 250 mL.

Answer:

Fewer bubbles will be produced because of fewer collisions of reactant molecules

Explanation:

As the solid dissolves into the solution after the liquid has been vigorously bubbled, if the temperature of the liquid is reduced a little, what will happen is that fewer bubbles will be produced as a result of lesser amount of collisions occurring between the reactant molecules

Answer:

11x³ – 2x² + 3x + 11

Explanation:

From the question given above:

We are to find the sum of:

4x³ + 2x² – 4x + 3 and 7x³ – 4x² + 7x + 8

To add the above polynomials together we must recognise that we can only add like terms together. The sum of the above polynomials can be obtained as follow:

. 4x³ + 2x² – 4x + 3

+ 7x³ – 4x² + 7x + 8

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

= 11x³ – 2x² + 3x + 11

Thus, the sum of 4x³ + 2x² – 4x + 3 and 7x³ – 4x² + 7x + 8 is 11x³ – 2x² + 3x + 11
