When ionic solids dissolve in water, they produce soluble aqueous cations and anions. For example, adding MgBr2 solids to water

will produce ions according to the dissolution reaction below.MgBr2(s) ? Mg2+(aq) + 2 Br?(aq)
solid cation anionIn this lab, you will be mixing two solutions containing soluble ions and observing any reactions that occur. Please write the dissolution reaction for the ionic solid Al(NO3)3.(Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer. Explain each step.)

Answer:

Al(NO3)3(s)--------> Al^3+(aq) + 3NO3^-(aq)

Explanation:

The equation shown above describes the dissolution of Al(NO3)3 in water using the lowest coefficients.

This occurs when solid Al(NO3)3 is added to water. It dissolves to give rise to ions as shown. This is a property of all ionic substances.

PLEASE HELP QUICK!! WILL MARK BRAINLIEST ANSWER!! When water is diffused across a selectively permeable membrane, scientists ref
xxTIMURxx [149]

Answer :

During diffusion, when the concentration of the molecules on both sides of the membrane is the same, the molecules will continue to move across the membrane in both the direction.

Answer 3 : It allows single-celled organism to reproduce, and other organism to repair damage tissues and grow.

Answer 4: The nucleus is an organelle that is surrounded by the cytoplasm, a jelly-like fluid.

Explanation :

Diffusion : It is a process where liquid moves from higher concentration to the lower concentration through permeable membrane.

When the concentration of the molecules on both sides of the membrane is same and the membrane is permeable membrane then diffusion will occur and the molecules will moves continuously across the membrane in both the direction.

Answer 3 :

Mitosis : It is a process of cell division. In this process, nucleus divides into two daughter cell and each daughter cell contains same number of chromosomes as present in parent nucleus.

The main purpose of the mitosis is to repair damaged tissues and growth.

Answer 4 :

Nucleus is a type of cell organelle. It is present in both animal and plant cells and it is the brain of the cell. It is present only in eukaryotic cell.

Nucleus is an organelle which is surrounded by the cell membrane which protects its from the other cells.

Cytoplasm is a jelly-like fluid which is present in the cell membrane which is made up of salt and water.

2. Extract the relevant information from the question: NaOH V = 30 mL , M = 0.10 M HCl V = 25.0 mL, M = ?
Andrei [34K]

Answer:

0.12M

Explanation:

A balanced equation for the reaction will go a great deal in obtaining our desired result. So, let us write a balanced equation for the reaction

HCl + NaOH —> NaCl + H2O

From the above equation,

nA (mole of the acid) = 1

nB (mole of the base) = 1

Data obtained from the question include:

Vb (volume of the base) = 30mL

Mb (Molarity of the base) = 0.1M

Va (volume of the acid) = 25mL

Ma (Molarity of the acid) =?

The molarity of the acid can be obtained as follow:

MaVa/MbVb = nA/nB

Ma x 25/ 0.1 x 30 = 1

Cross multiply to express in linear form

Ma x 25 = 0.1 x 30

Divide both side by 25

Ma = (0.1 x 30) / 25

Ma = 0.12M

The molarity of the acid is 0.12M

Predict the missing product of this equation<br><br><br>1 MgF2 + 1 Li2CO3 -&gt; 1 ______ +2LiF
ch4aika [34]

Answer:

MgCO₃

Explanation:

From the question given above, we obtained:

MgF₂ + Li₂CO₃ —> __ + 2LiF

The missing part of the equation can be obtained by writing the ionic equation for the reaction between MgF₂ and Li₂CO₃. This is illustrated below:

MgF₂ (aq) —> Mg²⁺ + 2F¯

Li₂CO₃ (aq) —> 2Li⁺ + CO₃²¯

MgF₂ + Li₂CO₃ —>

Mg²⁺ + 2F¯ + 2Li⁺ + CO₃²¯ —> Mg²⁺CO₃²¯ + 2Li⁺F¯

MgF₂ + Li₂CO₃ —> MgCO₃ + 2LiF

Now, we share compare the above equation with the one given in the question above to obtain the missing part. This is illustrated below:

MgF₂ + Li₂CO₃ —> __ + 2LiF

MgF₂ + Li₂CO₃ —> MgCO₃ + 2LiF

Therefore, the missing part of the equation is MgCO₃
