Answer:

v₁ = 7.5mL

Explanation:

using the formula

m₁v₁=m₂v₂

given m₁=10x m₂=1x v₁=? v₂=75mL

10x × v₁ = 1x × 75mL

v₁ = 1x × 75mL / 10x

v₁ = 7.5mL

So, 7.5mL of 10x PBS should be added with 67.5mL of water

Consider the reaction C2H4(g) + H2O(g) --> CH3CH2OH(g)
arsen [322]

Answer:

K = 361.369

Explanation:

C2H4(g) + H2O(g) → CH3CH2OH(g)

∴ ΔG°f(298.15K) CH3CH2OH(g) = - 174.8 KJ/mol

∴ ΔG°f(298.15) C2H4(g) =  68.4 KJ/mol

∴ ΔG°f(298.15) H2O(g) = - 228.6 KJ/mol

⇒ ΔG°f(298.15) = - 174.8 - ( - 228.6 + 68.4 ) = - 14.6 KJ/mol

  • K = e∧(-ΔG°f / RT)

∴ R = 8.314 E-3 KJ/mol.K

∴ T = 298.15 K

⇒ K = e∧(-(-14.6)/((8.314 E-3)(298.15)))

⇒ K = e∧(5.889)

⇒ K = 361.369

A room that is 500 cm x 400 cm x 250 cm contains 65 kg of air. Determine the volume of air in the room and its density.
seropon [69]

Answer:

1.3g/L is the density of the air

Explanation:

The room is full of air, the space that the air occupy is:

500 cm x 400 cm x 250 cm = 5.00x10⁷ cm³

The density of a substance is defined as the ratio between the mass of the substance and the space that occupy. We can express the density of air in g/L:

<em>Grams air:</em>

65 kg  * (1000g / 1kg) = 65000g

<em>Liters:</em>

5.00x10⁷ cm³ * (1L / 1000cm³) = 50000L

<em>Density:</em>

65000g / 50000L =

<h3>1.3g/L is the density of the air </h3>

An unknown hydrocarbon reacts with oxygen to produce carbon dioxide and water. The number of oxygen molecules in the reactants i
zavuch27 [327]

Explanation:

Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat. Hydrocarbons are molecules consisting of both hydrogen and carbon. They are most famous for being the primary constituent of fossil fuels, namely natural gas, petroleum, and coal. For this reason, fossil fuel resources are often referred to as hydrocarbon resources.[1] Energy is obtained from fossil fuels through combustion (burning) of the fuel. Although impurities exist in fossil fuels, hydrocarbon combustion is the primary process in the burning of fossil fuel.

What are ions and how do they work please send me answer​
PolarNik [594]

Answer:

hope it helps

please mark me brainliest

Explanation:

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
