Answer: exothermic

EXPLANATION: any process in which heat energy is released is called an exothermic process. For example burning of wood produces heat, so combustion of wood is an exothermic process.

When chemicals were not mixed they were at room temperature and when we mix them exothermic reaction took place and heat was released which raised the temperature of mixture.

Using the van der Waals equation, determine the pressure of 500.0 g of SO2(g) in a 6.30-L vessel at 633 K. For SO2(g), a = 6.865
dem82 [27]

Answer:

The pressure is 58.75 atm.

Explanation:

From Vanderwaal's equation,

P = nRT/(V-nb) - n^2a/V^2

n is the number of moles of SO2 = mass/MW = 500/64 = 7.81 mol

R is gas constant = 0.0821 L.atm/mol.K

T is temperature of the vessel = 633 K

V is volume of the vessel = 6.3 L

a & b are Vanderwaal's constant = 6.865 L^2.atm/mol^2 and 0.0567 L/mol respectively.

P = (7.81×0.0821×633)/(6.3 - 7.81×0.05679) - (7.81^2 × 6.865)/6.3^2 = 69.30 - 10.55 = 58.75 atm

What vesicular transport process do you think is involved in the toxin entering the neuron?
Masja [62]
There are two types of vesicular transport processes, exocytosis and endocytosis. Endocytosis is the process which is involved in the toxin entering the neuron. This process is where cells intake waste or chemical transmitters which are suspended or dissolved in the extracellular fluid around the cell. <span />

After precipitation falls, the water moves into the lithosphere through
Pie

After precipitation falls, the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.

Therefore, Option C is the correct option.

<h3>What is Evaporation? </h3>

Evaporation is defined as the process of conversion of liquid into vapours.

For example: Conversation of water into water vapours.

But int he question, there is no conversion. So this option is incorrect option.

<h3>What is Sublimation?</h3>

Sublimation is the process of conversion of solid directly into the vapour phase

Since, there is no conversion of of solid into vapours. So, this option also incorrect option.

<h3>What is Mineralization? </h3>

Mineralization is defined as the process through which chemicals which is present in organic matter are decomposed or oxidized easily in the available forms to plants.

As there is no decomposition of minerals. So, this is also incorrect option.

<h3>What is Percolation? </h3>

Percolation is defined as the process in which liquid slowly allow to pass through a filter.

So, this is correct option.

Thus, we concluded that the water moves into the lithosphere through openings in the rock or soil. This process is called percolation.
