If Captain America exerted a force of 50N and Iron Man exerted a force of 65N in the opposite direction, what would the outcome be? What is the net force? Who would be pushed backward?

Answer:

Option (2)

Explanation:

Boyle's states that at constant temperature, volume of a gas is inversely proportional to the pressure exerted by the gas.

In other words, at constant temperature, multiplication of pressure and volume of the gas is constant.

PV = k

Here 'k' = constant

From the graph attached,

[tex](V_3,P_3)[/tex] represents (0.5, 200).

0.5 × 200 = k

k = 100

For pressure 'P' = 150 kPa

150 × V = 100

V = [tex]\frac{100}{150}[/tex]

V = 0.67 L

Option (2) is the answer.

Hi!there are 8 planets in the solar system they are=

(there was one more planet Pluto but in 2006 scientists said that Pluto was not a planet but a drawf planet)

Answer:

Ye,,it is true that Mars is bigger than mercury.

Explanation:

Actually,Mercury is the smallest planet in the solar system.

Answer:

It is Sample 3, so C

Explanation:

This is because most metals would be solid but this is probualy mercury and it has a pretty low boiling point, and all the other samples are either weak/break easily with a hammer which metals dont do that, and theres a gas, obviously not so if you use process of elimation and common sense, its C

Answer:

3*0.35L = 1.05L

Explanation:

For part A, we need the ratio of moles of propane to moles of oxygen to get the volume of oxygen required.

The equation tells us there are 5 moles of oxygen gas required to combust 1 mole of propane.

So the required volume of oxygen is 5*0.35L = 1.75L

The equation also tells us that 3 moles of carbon dioxide are produced from the combustion of one mole of propane.

Therefore the produced volume of carbon dioxide is 3*0.35L = 1.05L

Answer: It requires heat as a reactant.

Answer:

0.43 M

Explanation:

Use the dilution equation: M1V1 = M2V2

M1 = 13 M

V1 = 10 mL

M2 = ?

V2 = 300 mL

Solve for M2 --> M2 = M1V1/V2

M2 = (13 M)(10 mL) / (300 mL) = 0.43 M

Answer: To solve this question, we need to use the Avogadro's Number, which is a constant first discovered by Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are 6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:

So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent 14,12 moles of Na₂SO₃

Explanation:

The number of moles is equal to 14.1 moles in 8.5 × 10²⁴ molecules of Na₂SO₄.

Avogadro’s number can be demonstrated as the number of particles in one mole of any substance. Generally, these units can be ions, molecules, atoms, electrons, or protons, depending upon the reaction or reactant and product.

The value of Avogadro’s constant is calculated approximately equal to 6.022 × 10²³ per mole. This number was named after the name of scientist Amedeo Avogadro.

Given, the molecules of the sodium sulfate =  8.5 × 10²⁴

One mole of sodium sulfate (Na₂SO₄) has molecules = 6.022 × 10²³

So, 6.022 × 10²³ molecules of sodium sulfate  = 1 mole

8.5 × 10²⁴molecules of Na₂SO₄ has moles =8.5 × 10²⁴/6.022 × 10²³

The number of moles of sodium sulfate = 14.2 mol

Therefore, 14.1 moles of sodium sulfate in 8.50 × 10²⁴ molecules of Na₂SO₄.

#SPJ2

Answer:

An example of heatwaves showing physical and chemical change is with a burning candle, when a candle burns, there is both a physical and chemical reaction.

The physical change is quite obvious and in fact, it can be seen. When the candle burns, the wax slowly melts and the candle gets smaller and smaller. This wax, as can be seen, will drip onto the candle and stick to it. When this wax forms back into a solid and stays on the candle, that is another physical change that can occur.

The chemical reaction can be a little less obvious. The first is that the heat produced by the candle consumes both the oxygen around it, as well as the fuels coming from the flame. This will then lead to carbon dioxide emissions produced by the flame, which by the way should never be inhaled. This is the chemical change that takes place in the reaction.

Answer: Salt is a chemical compound with a number of interesting properties: Crystals or white crystalline powder. Transparent and colourless in crystalline form – rather like ice. Crystallises in the isometric system, usually in the form of cubes.

Explanation:

A decreasing temperature indicates that the dissolution process for the ammonium chloride requires input of energy from surroundings. That is, the process is essentially 2 parts => system (object of interest - NH₄Cl) and the surroundings (everything else - solvent - H₂O). The surroundings (water) solvent is showing a measured decrease in temperature or loss of energy (exothermic to surroundings) which flows into the system (NH₄Cl) and effects dissolution of salt into solution (endothermic to system).
