How does an igneous or metamorphic rock become a sedimentary rock?

ella [17]

Answer: Usually, the rock pieces, called sediments, drop from the wind or water to make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be cemented together to make sedimentary rock. In this way, igneous rock can become sedimentary rock.

A 10.0-gram sample of which element has the smallest volume at STP?

DaniilM [7]

(4) zinc

Explanation:

Given parameters:

Mass of the sample = 10g

Condition = STP

Unknown:

Element with the least volume = ?

Solution:

The number of moles of substance as STP can be derived using the equation below;

Volume of substance = number of moles x 22.4

Number of moles = $\frac{mass}{molar mass}$

since mass = 10g

Number of moles of Al = $\frac{10}{27}$ = 0.37mole

Number of moles of Ti = $\frac{10}{47.9}$ = 0.29mole

number of moles of Mg = $\frac{10}{24}$ = 0.47mole

Number of moles of Zn = $\frac{10}{65.5}$ = 0.15mole

Zinc has the least number moles and it will have the lowest volume at STP because the volume directly proportional to number of moles.

A room is a cube that measures 4 meters in each dimension. If the temperature changes from 10 C to 30 C, and the pressure decrea

Katen [24]

Answer:

More air will enter the room since the volume of the room increases.

Explanation:

We'll begin by calculating the initial volume (V₁) of the room. This can be obtained as follow

Length (L) of room = 4 m

Initial volume (V₁) =..?

V₁ = L³

V₁ = 4³

V₁ = 64 m³

Next, we shall determine if there is an increase in the volume of the room or not. This can be obtained as follow:

Data obtained from the question include:

Initial volume (V₁) = 64 m³

Initial temperature (T₁) = 10 °C + 273 = 283 K

Final temperature (T₂) = 30 °C + 373 = 303 K

Initial pressure (P₁) = 760 mmHg

Final pressure (P₂) = 718 mmHg

Final volume (V₂) =?

P₁V₁/T₁ = P₂V₂/T₂

760 × 64 / 283 = 718 × V₂ / 303

48640 / 283 = 718 × V₂ / 303

Cross multiply

283 × 718 × V₂ = 48640 × 303

203194 × V₂ = 14737920

Divide both side by 203194

V₂ = 14737920 / 203194

V₂ = 72.53 m³

SUMMARY

Initial volume (V₁) of room = 64 m³

Final volume (V₂) of room = 72.53 m³

From the calculations made above, we can see that the volume of the room increases from 64 m³ to 72.53 m³. Thus more air will enter the room since the volume of the room increases.

Imagine you created a toxin such that when a neuron fired an action potential, the toxin would bind immediately to the sodium-po

loris [4]

Answer:Maintaining resting potential and returning to resting potential after the hyperpolarization phase of an action potential

Explanation:TOXINS are chemical substances which are known to be POISONOUS produced with living organisms that causes harm to other organisms, examples include Venom from snakes which when a person is bitten by a Snake it will possibly lead to death if not adequate treated.

HYPERPOLARIZATION is a term that explains the change in membrane potential due to toxin,it make the membrane more electronegative. When the toxin has hyped the level of Sodium-Potassium level returning to a rest state will be most affected.
