Explanation:

Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.

Answer:

Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2

Explanation:

On the left you have an original balance of Ca - 1, N - 2, O - 6, Na - 1, and Cl - 2, and on the right you have a balance of Ca - 1, N - 1, O - 3, Na - 1, Cl - 2.

Ca - 1 Ca - 1

N - 2 N - 1

O - 6 O - 3

Na - 1 Na - 1

Cl - 1 Cl - 2

In order to balance these, you'll have to make both sides equal. To get the N on the right to be equal to the N on the left, you'll have to multiply NaNO3 by 2, thus making it 2NaNO3. By doing this, you will offset the balance of both Na and O.

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 1 Na - 2

Cl - 1 Cl - 2

To balance the rest of the equation, you'll have to multiply both Na and Cl by 2. This will change NaCl to 2NaCl, making the balance look like this:

Ca - 1 Ca - 1

N - 2 N - 2

O - 6 O - 6

Na - 2 Na - 2

Cl - 2 Cl - 2

You will now be left with your final equation Ca(NO3)2 + 2 NaCl = 2 NaNO3 + CaCl2.

c

Explanation:

Answer:

a and c

Explanation:

The given reaction is an example of displacement reaction. Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen.

Displacement reactions are a kind of reactions where one element or group is displaced with other element or group. There are both single displacement and double displacement reaction.

The reaction of sulfur oxide with metallic copper producing copper oxide and copper sulphide is an example of single displacement reaction. The prior reaction for this is the combination of sulfur and oxygen.

Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen. Thus each is reacting in 1 :1 ratio and giving the oxide of sulfur.

Answer:

Most substances on earth are compounds and most interesting chemistry is done with compounds. Most interesting chemistry is done with mixtures of compounds although they often start with pure compounds and then do reactions as mixtures. Most chemistry is carried out in liquid solutions made up of compounds that are solids, liquids, or gases in their pure form.

Explanation:

Here, we are required to determine which of these methods of classifying substances is most important to chemists.

First classification of substances involves categorising them as pure substances (elements and compounds) or mixtures.

The second classification of substances is categorisation with respect to their state of matter. In essence, we can have solid, liquid or gas.

This is so because, the type of matter present in Elements are distinct for each element, same as for Compounds and Mixtures formed from a combination of pure substances.

Answer:

By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.

A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.

It is the degree of acidity or alkalinity of solutions.

pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.

Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.
