water is a ____ molecule meaning the positive hydrogen end attracts the negative oxygen ends of another

A. balance
B.universal
C. wet
D.polar

please answer! will give brainliest

Answers

Water is a polar molecule that gives rise to this phenomenon.

Water is a polar molecule where,  the positive hydrogen end attracts the negative oxygen ends of another water molecule. Thus, option D is correct.

What is polarity ?

Polarity is ability of charge separation in a molecule. In some molecules, the positive and negative ends exists separately and both ends remains reactive towards the counter charged end of other molecule.

The charge separation  in molecules results in a  dipole moment. Permanent dipole moment make the molecule polar. Water is a polar molecule.

The shared pair of electrons in water are more attracted towards the electronegative oxygen atom leads the charge separation. This polarity helps to the formation of strong intermolecular hydrogen bonding.

___Li + ___AlPO4 --> ___Al + ___Li3PO4

If 2.3 moles of Aluminum Phosphate are reacted, how many grams of Lithium Phosphate are produced?

Answers

Answer:

266.3 g

Explanation:

__Li + __AlPO₄ → __Al + __Li₃PO₄

The balanced reaction is:

3Li + AlPO₄ → Al + Li₃PO₄

First we convert 2.3 moles of AlPO₄ to moles of Li₃PO₄, using the stoichiometric coefficients:

2.3 mol AlPO₄ * [tex]\frac{1molLi_3PO_4}{1molAlPO_4}[/tex] = 2.3 mol Li₃PO₄

Then we convert Li₃PO₄ moles into grams, using its molar mass:

2.3 mol Li₃PO₄ * 115.79 g/mol = 266.3 g

A tank of gas is found to exert 8.6 atm at 38°C. What would be the required
temperature to change the pressure to standard pressure?

Answers

Answer:

36.2 K

Explanation:

Step 1: Given data

Initial pressure of the gas (P₁): 8.6 atmInitial temperature of the gas (T₁): 38°CFinal pressure of the gas (P₂): 1.0 atm (standard pressure)Final temperature of the gas (T₂): ?

Step 2: Convert T₁ to Kelvin

We will use the following expression.

K = °C +273.15

K = 38 °C +273.15 = 311 K

Step 3: Calculate T₂

We will use Gay Lussac's law.

P₁/T₁ = P₂/T₂

T₂ = P₂ × T₁/P₁

T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K
