A mass of 2.20 kg of sodium phosphate is converted into the following number of moles

Molarity is the molar concentration of the solution with respect to the moles and the volume. The molarity of the magnesium ion will be 0.339 M, and the Bromium ion will be 0.678M.

Molarity is the proportion of the moles of the solute to the volume in liters of the solution present. The compound magnesium bromide completely dissociates as:

MgBr² ⇆  Mg⁺² + 2Br⁻

The molarity of the magnesium ion will be equal to the M of the magnesium bromide and hence, will be 0.339 M.

The molarity of the bromide ions will be equal to two times the M of the magnesium bromide species and hence is 0.678 M.

Therefore, the molarity of the magnesium ion will be 0.339 M, and the Bromium ion will be 0.678M.

Answer:

Only A., the stick structure with no branches and five vertices between the two endpoints.

Explanation:

An alkane is a saturated hydrocarbon compound with no branches- just a series of carbon atoms connected with [tex]{\rm C}-{\rm C}[/tex] single bonds. Heptane is the name for an alkane with [tex]7[/tex] carbon atoms (the prefix "[tex]\verb!hept-![/tex]" means "seven".)

Notice that there are only [tex]6[/tex] carbon atoms in the alkane with the condensed structure formula [tex]{\rm CH_{3}}({\rm CH_{2})_{4}{\rm CH_{3}}[/tex]. The name for that structure would be hexane, not heptane.

In general, the condensed structure formula of an alkane with [tex]n[/tex] carbon atoms ([tex]n > 2[/tex]) is [tex]{\rm CH_{3}}({\rm CH_{2}})_{n-2} {\rm CH_{3}}[/tex]. The correct condensed structure formula for heptane ([tex]n = 7[/tex]) would be [tex]{\rm CH_{3}}({\rm CH_{2}})_{5} {\rm CH_{3}}[/tex].

The structure in choice A is represented as a line-angle formula. As long as no letter is present in the formula, each vertex in the line-angle formula (including the endpoints) represents a carbon atom. Hence, the line-angle formula in choice A would represent a hydrocarbon with [tex]7[/tex] carbon atoms.

A single line denotes a single bond between atoms. All [tex]7[/tex] carbon atoms in this structure are thus joined in a line with [tex]{\rm C}-{\rm C}[/tex] single bonds. Hence, this structure denotes an alkane with [tex]7[/tex] carbon atoms- heptane.

Answer:

: The conductivity of electrolyte solutions: (a) 0.1 M NaCl (b) 0.05 M NaCl (c) 0.1 M HgCl2. An electrolyte solution conducts electricity because of the movement of ions in the solution (see above). The larger the concentration of ions, the better the solutions conducts. Weak electrolytes, such as HgCl2, conduct badly because they produce few ions when dissolved (low concentration of ions) and exist mainly in the form of molecules.

Explanation:

From The Ideal Gas Equation,

Therefore,

I think that when the temperature decreases, the pressure will decrease. When things are cooled, pressure decreases.

The new pressure of the gas would be 505.58 torr

According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.

This can be mathematically represented as: P1V1 = P2V2

In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL

Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr

The difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane

A cell is the structural and functional unit of an organism which is capable of existing alone as it contains organelles that perform specific functions.

The plant cell is covered by a rigid cell wall which contains cellulose as its outer covering.

The animal cell contains not cellulose cell wall at its out covering but instead it is covered by a cell membrane.

Therefore, the difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane.

Answer:

I think the answer might be yes..

Answer:

30N to the left.

Explanation:

There is no net vertical force as the 45N force upwards and the 45N force downwards cancel each other out.

Horizontally, the resultant force is the 30N to the left as the 45N force to the left is in opposite direction to the 15N force to the right, so they are subtracted:

                                          45N - 15N = 30N

Explanation:

The volume of water needed to prepare the solution given the data is 2.16 L

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

Mole = mass / molar mass

Mole of CaCO₃ = 756 / 100.1

Mole of CaCO₃ = 7.55 moles

Volume = mole / molarity

Volume = 7.55 / 3.5

Avogadro's numbers are used to convert the moles, atoms, and molecules. There are 51.17 × 10²¹ molecules in 8.5 x 10⁻² moles of HF.

Avogadro's number converts the moles into molecules with the help of the value of the Avogadro's number as 6.02 x 10²³.

We know that 1 mole of HF has 6.02 x 10²³ molecules

Then, 8.5 x 10⁻² moles of HF will have:

(8.5 x 10⁻²) × 6.02 x 10²³ = 51.17 × 10²¹ molecules.

Therefore, 51.17 × 10²¹ molecules are present in 8.5 x 10⁻² moles of HF.
